    The aim of this study was to examine logical positivist statistical probability statements used to support and justify "evidence-based" prescribing rules in psychiatry when viewed from the major philosophical theories of probability, and to propose "phenomenological probability" based on Maurice Merleau-Ponty's philosophy of "phenomenological positivism" as a better clinical and ethical basis for psychiatric prescribing. The logical positivist statistical probability statements which are currently used to support "evidence-based" prescribing rules in psychiatry have little clinical or ethical justification when subjected to critical analysis from any of the major theories of probability and represent dangerous "spin" because they necessarily exclude the individual , intersubjective and ambiguous meaning of mental illness. A concept of "phenomenological probability" founded on Merleau-Ponty's philosophy of "phenomenological positivism" overcomes the clinically destructive "objectivist" and "subjectivist" consequences of logical positivist statistical probability and allows psychopharmacological treatments to be appropriately integrated into psychiatric treatment.

    Background: “Dhat syndrome” is believed to be a culture-bound syndrome of the Indian subcontinent. Although many studies have been performed, many have methodological limitations and there is a lack of agreement in many areas. Aims: The aim is to study the phenomenology of “Dhat syndrome” in men and to explore the possibility of subtypes within this entity. Settings and Design: It is a cross-sectional descriptive study conducted at a sex and marriage counseling clinic of a tertiary care teaching hospital in Northern India. Materials and Methods: An operational definition and assessment instrument for “Dhat syndrome” was developed after taking all concerned stakeholders into account and review of literature. It was applied on 100 patients along with socio-demographic profile, Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, Mini International Neuropsychiatric Interview, and Postgraduate Institute Neuroticism Scale. Statistical Analysis: For statistical analysis, descriptive statistics, group comparisons, and Pearson's product moment correlations were carried out. Factor analysis and cluster analysis were done to determine the factor structure and subtypes of “Dhat syndrome.” Results: A diagnostic and assessment instrument for “Dhat syndrome” has been developed and the phenomenology in 100 patients has been described. Both the health beliefs scale and associated symptoms scale demonstrated a three-factor structure. The patients with “Dhat syndrome” could be categorized into three clusters based on severity. Conclusions: There appears to be a significant agreement among various stakeholders on the phenomenology of “Dhat syndrome” although some differences exist. “Dhat syndrome” could be subtyped into three clusters based on severity.

    While small at very high temperature, the bulk viscosity of Quantum Chromodynamics is expected to grow in the confinement region. Although its precise magnitude and temperature-dependence in the cross-over region is not fully understood, recent theoretical and phenomenological studies provided evidence that the bulk viscosity can be sufficiently large to have measurable consequences on the evolution of the quark-gluon plasma. In this work, a Bayesian statistical analysis is used to establish probabilistic constraints on the temperature-dependence of bulk viscosity using hadronic measurements from RHIC and LHC.

    An important problem in precision cosmology is the determination of the effects of averaging and backreaction on observational predictions, particularly in view of the wealth of new observational data and improved statistical techniques. In this paper, we discuss the observational viability of a class of averaged cosmologies which consist of a simple parametrized phenomenological two-scale backreaction model with decoupled spatial curvature parameters. We perform a Bayesian model selection analysis and find that this class of averaged phenomenological cosmological models is favored with respect to the standard ΛCDM cosmological scenario when a joint analysis of current SNe Ia and BAO datamore » is performed. In particular, the analysis provides observational evidence for non-trivial spatial curvature.« less

    The physical properties of granular materials have been extensively studied in recent years. So far, however, there exists no theoretical framework which can explain the observations in a unified manner beyond the phenomenological jamming diagram. This work focuses on the case of static granular matter, where we have constructed a statistical ensemble which mirrors equilibrium statistical mechanics. This ensemble, which is based on the conservation properties of the stress tensor, is distinct from the original Edwards ensemble and applies to packings of deformable grains. We combine it with a field theoretical analysis of the packings, where the field is the Airy stress function derived from the force and torque balance conditions. In this framework, Point J characterized by a diverging stiffness of the pressure fluctuations. Separately, we present a phenomenological mean-field theory of the jamming transition, which incorporates the mean contact number as a variable. We link both approaches in the context of the marginal rigidity picture proposed by Wyart and others.

  7. Statistical turbulence theory and turbulence phenomenology

    1973-01-01

    The application of deductive turbulence theory for validity determination of turbulence phenomenology at the level of second-order, single-point moments is considered. Particular emphasis is placed on the phenomenological formula relating the dissipation to the turbulence energy and the Rotta-type formula for the return to isotropy. Methods which deal directly with most or all the scales of motion explicitly are reviewed briefly. The statistical theory of turbulence is presented as an expansion about randomness. Two concepts are involved: (1) a modeling of the turbulence as nearly multipoint Gaussian, and (2) a simultaneous introduction of a generalized eddy viscosity operator.

    Twelve senior Kundalini (Chakra) meditators were assessed during meditation session and non-meditation or control session using Phenomenology of Consciousness Inventory. The data has been analyzed using structural analysis to measure the altered state of consciousness and the identity state by comparing meditative state with non-meditative state. The structural analysis of pattern of consciousness during the meditative state revealed altered experience in perception (percentile rank PR = 90), meaning (PR = 82) and time sense (PR = 87), while positive affect dimension showed increased joy (PR = 73) and love (PR = 67). The imagery vividness (PR = 72), self-awareness (PR = 77), rationality (PR = 73) and arousal (PR = 69) were found to be structurally different from the ordinary state. With regards to identity state meditative experience was found to produce statistically significant changes in terms of intensity in meaning (P < 0.05), time sense (P < 0.05), joy (P < 0.05), love (P < 0.05) and state of awareness (P < 0.01). Our results indicate that long term practice of meditation appears to produce structural as well as intensity changes in phenomenological experiences of consciousness.

    We present a by-product of our long term photometric monitoring of cataclysmic variables. 2MASS J18024395 +4003309 = VSX J180243.9 +400331 was discovered in the field of the intermediate polar V1323 Her observed using the Korean 1-m telescope located at Mt. Lemmon, USA. An analysis of the two-color VR CCD observations of this variable covers all the phase intervals for the first time. The light curves show this object can be classified as an Algol-type variable with tidally distorted components, and an asymmetry of the maxima (the O'Connell effect). The periodogram analysis confirms the cycle numbering of Andronov et al. (2012) and for the initial approximation, the ephemeris is used as follows: Min I. BJD = 2456074.4904+0.3348837E . For phenomenological modeling, we used the trigonometric polynomial approximation of statistically optimal degree, and a recent method "NAV" ("New Algol Variable") using local specific shapes for the eclipse. Methodological aspects and estimates of the physical parameters based on analysis of phenomenological parameters are presented. As results of our phenomenological model, we obtained for the inclination i=90°, M1=0.745M⊙, M2=0.854M⊙, M=M1+M2=1.599M⊙, the orbital separation a=1.65°109m=2.37R⊙ and relative radii r1=R1/a=0.314 and r2=R2/a=0.360. These estimates may be used as preliminary starting values for further modeling using extended physical models based on the Wilson & Devinney (1971) code and it's extensions

    This multimethod, qualitative study provides results for educators of nursing doctoral students to consider. Combining the expertise of an empirical analytical researcher (who uses statistical methods) and an interpretive phenomenological researcher (who uses hermeneutic methods), a course was designed that would place doctoral students in the midst of multiparadigmatic discussions while learning fundamental research methods. Field notes and iterative analytical discussions led to patterns and themes that highlight the value of this innovative pedagogical application. Using content analysis and interpretive phenomenological approaches, together with one of the students, data were analyzed from field notes recorded in real time over the period the course was offered. This article describes the course and the study analysis, and offers the pedagogical experience as transformative. A link to a sample syllabus is included in the article. The results encourage nurse educators of doctoral nursing students to focus educational practice on multiple methodological perspectives. Copyright 2014, SLACK Incorporated.

    2008-10-01

    The problem of characterizing damage evolution in a generic material is addressed with the aim of tracing it back to existing growth models in other fields of research. Based on energetic considerations, a system evolution equation is derived for a generic damage indicator describing a material system subjected to an increasing external stress. The latter is found to fit into the framework of a recently developed phenomenological universality (PUN) approach and, more specifically, the so-called U2 class. Analytical results are confirmed by numerical simulations based on a fiber-bundle model and statistically assigned local strengths at the microscale. The fits with numerical data prove, with an excellent degree of reliability, that the typical evolution of the damage indicator belongs to the aforementioned PUN class. Applications of this result are briefly discussed and suggested.

    In a recent paper, we proposed a ``paronic'' field-theory framework for possible small deviations from the Pauli exclusion principle. This theory cannot be represented in a positive-metric (Hilbert) space. Nonetheless, the issue of possible small violations of the exclusion principle can be addressed in the framework of quantum mechanics, without being connected with a local quantum field theory. In this paper, we discuss the phenomenology of small violations of both Fermi and Bose statistics. We consider the implications of such violations in atomic, nuclear, particle, and condensed-matter physics and in astrophysics and cosmology. We also discuss experiments that can detect small violations of Fermi and Bose statistics or place stringent bounds on their validity.

    2010-03-01

    This article contributes to the debate about phenomenology as a research approach in nursing by providing a systematic review of what nurse researchers hold as phenomenology in published empirical studies. Based on the assumption that presentations of phenomenological approaches in peer-reviewed journals have consequences for the quality of future research, the aim was to analyze articles presenting phenomenological studies and, in light of the findings, raise a discussion about addressing scientific criteria. The analysis revealed considerable variations, ranging from brief to detailed descriptions of the stated phenomenological approach, and from inconsistencies to methodological clarity and rigor. Variations, apparent inconsistencies, and omissions made it unclear what makes a phenomenological study phenomenological. There is a need for clarifying how the principles of the phenomenological philosophy are implemented in a particular study before publishing. This should include an articulation of methodological keywords of the investigated phenomenon, and how an open attitude was adopted.

    In the high energy limit, perturbative QCD predicts that hard scattering amplitudes should follow simple scaling laws. For hard scattering at 90°, we show that experiments support this prediction even in the “medium energy” regime of 2.3 GeV<=sqrt(s)<=2.84 GeV, as long as there are no s-channel resonances present. Our data consists of high statistics measurements for five different exclusive meson photoproduction channels (pomega, peta, peta[prime], K+Lambdaand K+[summation]0) recently obtained from CLAS at Jefferson Lab. The same power-law scaling also leads to “saturated” Regge trajectories at high energies. That is, at large -t and -u, Regge trajectories must approach constant negativemore » integers. We demonstrate the application of saturated Regge phenomenology by performing a partial wave analysis fit to the gammayp-->peta[prime]differential cross sections.« less

  20. Probabilistic risk assessment for a loss of coolant accident in McMaster Nuclear Reactor and application of reliability physics model for modeling human reliability

    NASA Astrophysics Data System (ADS)

    Ha, Taesung

    A probabilistic risk assessment (PRA) was conducted for a loss of coolant accident, (LOCA) in the McMaster Nuclear Reactor (MNR). A level 1 PRA was completed including event sequence modeling, system modeling, and quantification. To support the quantification of the accident sequence identified, data analysis using the Bayesian method and human reliability analysis (HRA) using the accident sequence evaluation procedure (ASEP) approach were performed. Since human performance in research reactors is significantly different from that in power reactors, a time-oriented HRA model (reliability physics model) was applied for the human error probability (HEP) estimation of the core relocation. This model is based on two competing random variables: phenomenological time and performance time. The response surface and direct Monte Carlo simulation with Latin Hypercube sampling were applied for estimating the phenomenological time, whereas the performance time was obtained from interviews with operators. An appropriate probability distribution for the phenomenological time was assigned by statistical goodness-of-fit tests. The human error probability (HEP) for the core relocation was estimated from these two competing quantities: phenomenological time and operators' performance time. The sensitivity of each probability distribution in human reliability estimation was investigated. In order to quantify the uncertainty in the predicted HEPs, a Bayesian approach was selected due to its capability of incorporating uncertainties in model itself and the parameters in that model. The HEP from the current time-oriented model was compared with that from the ASEP approach. Both results were used to evaluate the sensitivity of alternative huinan reliability modeling for the manual core relocation in the LOCA risk model. This exercise demonstrated the applicability of a reliability physics model supplemented with a. Bayesian approach for modeling human reliability and its potential usefulness of quantifying model uncertainty as sensitivity analysis in the PRA model.

    Higgs pair production is a crucial phenomenological process in deciphering the nature of the TeV scale and the mechanism underlying electroweak symmetry breaking. At the Large Hadron Collider, this process is statistically limited. Pushing the energy frontier beyond the LHC's reach will create new opportunities to exploit the rich phenomenology at higher centre-of-mass energies and luminosities. In this work, we perform a comparative analysis of the hh+ {jet} channel at a future 100 TeV hadron collider. We focus on the hh→ b\\bar{b} b\\bar{b} and hh → b\\bar{b} τ ^+τ ^- channels and employ a range of analysis techniques to estimate the sensitivity potential that can be gained by including this jet-associated Higgs pair production to the list of sensitive collider processes in such an environment. In particular, we observe that hh → b\\bar{b} τ ^+τ ^- in the boosted regime exhibits a large sensitivity to the Higgs boson self-coupling and the Higgs self-coupling could be constrained at the 8% level in this channel alone.

  2. Free will: A case study in reconciling phenomenological philosophy with reductionist sciences.

    PubMed

    Hong, Felix T

    2015-12-01

    Phenomenology aspires to philosophical analysis of humans' subjective experience while it strives to avoid pitfalls of subjectivity. The first step towards naturalizing phenomenology - making phenomenology scientific - is to reconcile phenomenology with modern physics, on the one hand, and with modern cellular and molecular neuroscience, on the other hand. In this paper, free will is chosen for a case study to demonstrate the feasibility. Special attention is paid to maintain analysis with mathematical precision, if possible, and to evade the inherent deceptive power of natural language. Laplace's determinism is re-evaluated along with the concept of microscopic reversibility. A simple and transparent version of proof demonstrates that microscopic reversibility is irreconcilably incompatible with macroscopic irreversibility, contrary to Boltzmann's claim. But the verdict also exalts Boltzmann's statistical mechanics to the new height of a genuine paradigm shift, thus cutting the umbilical cord linking it to Newtonian mechanics. Laplace's absolute determinism must then be replaced with a weaker form of causality called quasi-determinism. Biological indeterminism is also affirmed with numerous lines of evidence. The strongest evidence is furnished by ion channel fluctuations, which obey an indeterministic stochastic phenomenological law. Furthermore, quantum indeterminacy is shown to be relevant in biology, contrary to the opinion of Erwin Schrödinger. In reconciling phenomenology of free will with modern sciences, three issues - alternativism, intelligibility and origination - of free will must be accounted for. Alternativism and intelligibility can readily be accounted for by quasi-determinism. In order to account for origination of free will, the concept of downward causation must be invoked. However, unlike what is commonly believed, there is no evidence that downward causation can influence, shield off, or overpower low-level physical forces already known to physicists. Quasi-determinism offers an escape route: The possibility that downward causation arising from hierarchical organization of biological structures can modify dispersions of physical laws remains open. Empirical evidence in support of downward causation is scanty but nevertheless exists. Still, origination of free will must be considered an unsolved problem at present. It is demonstrated that objectivity does not guarantee scientific rigor in the study of complex phenomena, such as human creativity. In its replacement, universality and overall consistency between a theory and empirical evidence must be maintained. Visual thinking is proposed as a reasoning tool to ensure universality and overall consistency through inference to the best explanation. Copyright © 2015. Published by Elsevier Ltd.

  3. Phenomenology in Its Original Sense.

    PubMed

    van Manen, Max

    2017-05-01

    In this article, I try to think through the question, "What distinguishes phenomenology in its original sense?" My intent is to focus on the project and methodology of phenomenology in a manner that is not overly technical and that may help others to further elaborate on or question the singular features that make phenomenology into a unique qualitative form of inquiry. I pay special attention to the notion of "lived" in the phenomenological term "lived experience" to demonstrate its critical role and significance for understanding phenomenological reflection, meaning, analysis, and insights. I also attend to the kind of experiential material that is needed to focus on a genuine phenomenological question that should guide any specific research project. Heidegger, van den Berg, and Marion provide some poignant exemplars of the use of narrative "examples" in phenomenological explorations of the phenomena of "boredom," "conversation," and "the meaningful look in eye-contact." Only what is given or what gives itself in lived experience (or conscious awareness) are proper phenomenological "data" or "givens," but these givens are not to be confused with data material that can be coded, sorted, abstracted, and accordingly analyzed in some "systematic" manner. The latter approach to experiential research may be appropriate and worthwhile for various types of qualitative inquiry but not for phenomenology in its original sense. Finally, I use the mythical figure of Kairos to show that the famous phenomenological couplet of the epoché-reduction aims for phenomenological insights that require experiential analysis and attentive (but serendipitous) methodical inquiry practices.

  6. Hermeneutic phenomenological analysis: the 'possibility' beyond 'actuality' in thematic analysis.

    PubMed

    Ho, Ken H M; Chiang, Vico C L; Leung, Doris

    2017-07-01

    This article discusses the ways researchers may become open to manifold interpretations of lived experience through thematic analysis that follows the tradition of hermeneutic phenomenology. Martin Heidegger's thinking about historical contexts of understandings and the notions of 'alētheia' and 'techne' disclose what he called meaning of lived experience, as the 'unchanging Being of changing beings'. While these notions remain central to hermeneutic phenomenological research, novice phenomenologists usually face the problem of how to incorporate these philosophical tenets into thematic analysis. Discussion paper. This discussion paper is based on our experiences of hermeneutic analysis supported by the writings of Heidegger. Literature reviewed for this paper ranges from 1927 - 2014. We draw on data from a study of foreign domestic helpers in Hong Kong to demonstrate how 'dwelling' in the language of participants' 'ek-sistence' supported us in a process of thematic analysis. Data were collected from December 2013 - February 2016. Nurses doing hermeneutic phenomenology have to develop self-awareness of one's own 'taken-for-granted' thinking to disclose the unspoken meanings hidden in the language of participants. Understanding the philosophical tenets of hermeneutic phenomenology allows nurses to preserve possibilities of interpretations in thinking. In so doing, methods of thematic analysis can uncover and present the structure of the meaning of lived experience. We provide our readers with vicarious experience of how to begin cultivating thinking that is aligned with hermeneutic phenomenological philosophical tenets to conduct thematic analysis. © 2017 John Wiley & Sons Ltd.

    Summary Background Auditory hallucinations—or voices—are a common feature of many psychiatric disorders and are also experienced by individuals with no psychiatric history. Understanding of the variation in subjective experiences of hallucination is central to psychiatry, yet systematic empirical research on the phenomenology of auditory hallucinations remains scarce. We aimed to record a detailed and diverse collection of experiences, in the words of the people who hear voices themselves. Methods We made a 13 item questionnaire available online for 3 months. To elicit phenomenologically rich data, we designed a combination of open-ended and closed-ended questions, which drew on service-user perspectives and approaches from phenomenological psychiatry, psychology, and medical humanities. We invited people aged 16–84 years with experience of voice-hearing to take part via an advertisement circulated through clinical networks, hearing voices groups, and other mental health forums. We combined qualitative and quantitative methods, and used inductive thematic analysis to code the data and χ2 tests to test additional associations of selected codes. Findings Between Sept 9 and Nov 29, 2013, 153 participants completed the study. Most participants described hearing multiple voices (124 [81%] of 153 individuals) with characterful qualities (106 [69%] individuals). Less than half of the participants reported hearing literally auditory voices—70 (46%) individuals reported either thought-like or mixed experiences. 101 (66%) participants reported bodily sensations while they heard voices, and these sensations were significantly associated with experiences of abusive or violent voices (p=0·024). Although fear, anxiety, depression, and stress were often associated with voices, 48 (31%) participants reported positive emotions and 49 (32%) reported neutral emotions. Our statistical analysis showed that mixed voices were more likely to have changed over time (p=0·030), be internally located (p=0·010), and be conversational in nature (p=0·010). Interpretation This study is, to our knowledge, the largest mixed-methods investigation of auditory hallucination phenomenology so far. Our survey was completed by a diverse sample of people who hear voices with various diagnoses and clinical histories. Our findings both overlap with past large-sample investigations of auditory hallucination and suggest potentially important new findings about the association between acoustic perception and thought, somatic and multisensorial features of auditory hallucinations, and the link between auditory hallucinations and characterological entities.

    The relative biological effectiveness (RBE) of protons varies with the radiation quality, quantified by the linear energy transfer (LET). Most phenomenological models employ a linear dependency of the dose-averaged LET (LET d ) to calculate the biological dose. However, several experiments have indicated a possible non-linear trend. Our aim was to investigate if biological dose models including non-linear LET dependencies should be considered, by introducing a LET spectrum based dose model. The RBE-LET relationship was investigated by fitting of polynomials from 1st to 5th degree to a database of 85 data points from aerobic in vitro experiments. We included both unweighted and weighted regression, the latter taking into account experimental uncertainties. Statistical testing was performed to decide whether higher degree polynomials provided better fits to the data as compared to lower degrees. The newly developed models were compared to three published LET d based models for a simulated spread out Bragg peak (SOBP) scenario. The statistical analysis of the weighted regression analysis favored a non-linear RBE-LET relationship, with the quartic polynomial found to best represent the experimental data (P = 0.010). The results of the unweighted regression analysis were on the borderline of statistical significance for non-linear functions (P = 0.053), and with the current database a linear dependency could not be rejected. For the SOBP scenario, the weighted non-linear model estimated a similar mean RBE value (1.14) compared to the three established models (1.13-1.17). The unweighted model calculated a considerably higher RBE value (1.22). The analysis indicated that non-linear models could give a better representation of the RBE-LET relationship. However, this is not decisive, as inclusion of the experimental uncertainties in the regression analysis had a significant impact on the determination and ranking of the models. As differences between the models were observed for the SOBP scenario, both non-linear LET spectrum- and linear LET d based models should be further evaluated in clinically realistic scenarios. © 2017 American Association of Physicists in Medicine.

  9. A phenomenological calculus of Wiener description space.

    PubMed

    Richardson, I W; Louie, A H

    2007-10-01

    The phenomenological calculus is a categorical example of Robert Rosen's modeling relation. This paper is an alligation of the phenomenological calculus and generalized harmonic analysis, another categorical example. Our epistemological exploration continues into the realm of Wiener description space, in which constitutive parameters are extended from vectors to vector-valued functions of a real variable. Inherent in the phenomenology are fundamental representations of time and nearness to equilibrium.

  10. Developing a cosmic ray muon sampling capability for muon tomography and monitoring applications

    NASA Astrophysics Data System (ADS)

    Chatzidakis, S.; Chrysikopoulou, S.; Tsoukalas, L. H.

    2015-12-01

    In this study, a cosmic ray muon sampling capability using a phenomenological model that captures the main characteristics of the experimentally measured spectrum coupled with a set of statistical algorithms is developed. The "muon generator" produces muons with zenith angles in the range 0-90° and energies in the range 1-100 GeV and is suitable for Monte Carlo simulations with emphasis on muon tomographic and monitoring applications. The muon energy distribution is described by the Smith and Duller (1959) [35] phenomenological model. Statistical algorithms are then employed for generating random samples. The inverse transform provides a means to generate samples from the muon angular distribution, whereas the Acceptance-Rejection and Metropolis-Hastings algorithms are employed to provide the energy component. The predictions for muon energies 1-60 GeV and zenith angles 0-90° are validated with a series of actual spectrum measurements and with estimates from the software library CRY. The results confirm the validity of the phenomenological model and the applicability of the statistical algorithms to generate polyenergetic-polydirectional muons. The response of the algorithms and the impact of critical parameters on computation time and computed results were investigated. Final output from the proposed "muon generator" is a look-up table that contains the sampled muon angles and energies and can be easily integrated into Monte Carlo particle simulation codes such as Geant4 and MCNP.

  11. Service user involvement enhanced the research quality in a study using interpretative phenomenological analysis - the power of multiple perspectives.

    The aim of this study was to examine how service user involvement can contribute to the development of interpretative phenomenological analysis methodology and enhance research quality. Interpretative phenomenological analysis is a qualitative methodology used in nursing research internationally to understand human experiences that are essential to the participants. Service user involvement is requested in nursing research. We share experiences from 4 years of collaboration (2012-2015) on a mental health promotion project, which involved an advisory team. Five research advisors either with a diagnosis or related to a person with severe mental illness constituted the team. They collaborated with the research fellow throughout the entire research process and have co-authored this article. We examined the joint process of analysing the empirical data from interviews. Our analytical discussions were audiotaped, transcribed and subsequently interpreted following the guidelines for good qualitative analysis in interpretative phenomenological analysis studies. The advisory team became 'the researcher's helping hand'. Multiple perspectives influenced the qualitative analysis, which gave more insightful interpretations of nuances, complexity, richness or ambiguity in the interviewed participants' accounts. The outcome of the service user involvement was increased breadth and depth in findings. Service user involvement improved the research quality in a nursing research project on mental health promotion. The interpretative element of interpretative phenomenological analysis was enhanced by the emergence of multiple perspectives in the qualitative analysis of the empirical data. We argue that service user involvement and interpretative phenomenological analysis methodology can mutually reinforce each other and strengthen qualitative methodology. © 2016 The Authors.

    PubMed

    Vellone, E; Sinapi, N; Rastelli, D

    2000-01-01

    Phenomenology is a thought movement the main aim of which is to study human fenomena as they are experienced and lived. Key concepts of phenomenology are: the study of lived experience and subjectivity of human beings, the intentionality of consciousness, perception and interpretation. Phenomenological research method has nine steps: definition of the research topic; superficial literature searching; sample selection; gathering of lived experiences; analysis of lived experiences; written synthesis of lived experiences; validation of written synthesis; deep literature searching; writing of the scientific document. Phenomenology and phenomenological method are useful for nursing either to develop knowledge or to guide practice. Qualitative-phenomenological and quantitative-positivistic research are complementary: the first one guides clinicians towards a person-centered approach, the second one allows the manipulation of phenomena which can damage health, worsen illness or decrease the quality of life of people who rely on nursing care.

    2007-10-05

    We inquire into the scaling properties of the 2D Navier-Stokes equation sustained by a force field with Gaussian statistics, white noise in time, and with a power-law correlation in momentum space of degree 2 - 2 epsilon. This is at variance with the setting usually assumed to derive Kraichnan's classical theory. We contrast accurate numerical experiments with the different predictions provided for the small epsilon regime by Kraichnan's double cascade theory and by renormalization group analysis. We give clear evidence that for all epsilon, Kraichnan's theory is consistent with the observed phenomenology. Our results call for a revision in the renormalization group analysis of (2D) fully developed turbulence.

    The plasma environment encountered by the Next Generation Space Telescope satellite in a halo orbit about L2 can include the Earth's magnetotail and magnetosheath in addition to the solar wind depending on the orbital radius chosen for the mission. Analysis of plasma environment impacts on the satellite requires knowledge of the average and extreme plasma characteristics to assess the magnitude of spacecraft charging and materials degradation expected for the mission lifetime. This report describes the analysis of plasma data from instruments onboard the IMP 8 and Geotail spacecraft used to produce the plasma database for the LRAD engineering-level phenomenology code developed to provide the NGST L2 environment definition.

  19. Tip-of-the-tongue phenomena: an introductory phenomenological analysis.

    PubMed

    Brown, S R

    2000-12-01

    The issue of meaningful yet unexpressed background-to language and to our experiences of the body-is one whose exploration is still in its infancy. There are various aspects of "invisible," implicit, or background experiences which have been investigated from the viewpoints of phenomenology, cognitive psychology, and linguistics. I will argue that James's concept of the phenomenon of fringes, as explicated by Gurwitsch, provides a structural framework from which to investigate and better understand ideas and concepts that are indeterminate, particularly those experienced in the sense of being sought-after. Johnson's conception of the image-schematic gestalt (ISG) provides an approach to bridging the descriptive gap between phenomenology and cognitive psychology. Starting from an analysis of the fringes, I will turn to a consideration of the tip-of-tongue (TOT) state, as a kind of feeling-of-knowing (FOK) state, from a variety of approaches, focusing mainly on cognitive psychology and phenomenology. I will then integrate a phenomenological analysis of these experiences, from the James/Gurwitsch structural viewpoint, with a cognitive/phenomenological analysis in terms of ISGs, and further integrate that with a cognitive/functional analysis of the relation between consciousness and retrieval, employing Anderson et al's theory of inhibitory mechanisms in cognition. This synthesis of these viewpoints will be employed to explore the thesis that the TOT state and similar experiences may relate to the gestalt nature of schemas, and that figure/ground and other contrast-enhancing structures may be both explanatory and descriptive characterizations of the field of consciousness.

    2014-01-01

    This report documents the phenomenology of the subjective experiences of 15 healthy psychedelic experienced volunteers who were involved in a functional magnetic resonance imaging (fMRI) study that was designed to image the brain effects of intravenous psilocybin. The participants underwent a semi-structured interview exploring the effects of psilocybin in the MRI scanner. These interviews were analysed by Interpretative Phenomenological Analysis. The resultant data is ordered in a detailed matrix, and presented in this paper. Nine broad categories of phenomenology were identified in the phenomenological analysis of the experience; perceptual changes including visual, auditory and somatosensory distortions, cognitive changes, changes in mood, effects of memory, spiritual or mystical type experiences, aspects relating to the scanner and research environment, comparisons with other experiences, the intensity and onset of effects, and individual interpretation of the experience. This article documents the phenomenology of psilocybin when given in a novel manner (intravenous injection) and setting (an MRI scanner). The findings of the analysis are consistent with previous published work regarding the subjective effects of psilocybin. There is much scope for further research investigating the phenomena identified in this paper.

  7. Statistical mechanics of simple models of protein folding and design.

    1997-01-01

    It is now believed that the primary equilibrium aspects of simple models of protein folding are understood theoretically. However, current theories often resort to rather heavy mathematics to overcome some technical difficulties inherent in the problem or start from a phenomenological model. To this end, we take a new approach in this pedagogical review of the statistical mechanics of protein folding. The benefit of our approach is a drastic mathematical simplification of the theory, without resort to any new approximations or phenomenological prescriptions. Indeed, the results we obtain agree precisely with previous calculations. Because of this simplification, we are able to present here a thorough and self contained treatment of the problem. Topics discussed include the statistical mechanics of the random energy model (REM), tests of the validity of REM as a model for heteropolymer freezing, freezing transition of random sequences, phase diagram of designed ("minimally frustrated") sequences, and the degree to which errors in the interactions employed in simulations of either folding and design can still lead to correct folding behavior.

    2006-11-01

    This paper is concerned with illuminating how emotion (anger) and emotion-related phenomena such as feelings, thoughts and expressions appear to the individual person. In particular, it focuses on the role of feelings in emotion experience. It does this through the qualitative analysis of interview material from a single person case study using interpretative phenomenological analysis. The paper examines how the participant feels and experiences anger, the defining characteristics of anger episodes, and how the typical pattern of these episodes is disrupted by life-changes. The findings are examined in light of phenomenological ideas and the utility of these ideas for psychology's understanding of emotion argued for.

  9. Low energy peripheral scaling in nucleon-nucleon scattering and uncertainty quantification

    NASA Astrophysics Data System (ADS)

    Ruiz Simo, I.; Amaro, J. E.; Ruiz Arriola, E.; Navarro Pérez, R.

    2018-03-01

    We analyze the peripheral structure of the nucleon-nucleon interaction for LAB energies below 350 MeV. To this end we transform the scattering matrix into the impact parameter representation by analyzing the scaled phase shifts (L + 1/2) δ JLS (p) and the scaled mixing parameters (L + 1/2)ɛ JLS (p) in terms of the impact parameter b = (L + 1/2)/p. According to the eikonal approximation, at large angular momentum L these functions should become an universal function of b, independent on L. This allows to discuss in a rather transparent way the role of statistical and systematic uncertainties in the different long range components of the two-body potential. Implications for peripheral waves obtained in chiral perturbation theory interactions to fifth order (N5LO) or from the large body of NN data considered in the SAID partial wave analysis are also drawn from comparing them with other phenomenological high-quality interactions, constructed to fit scattering data as well. We find that both N5LO and SAID peripheral waves disagree more than 5σ with the Granada-2013 statistical analysis, more than 2σ with the 6 statistically equivalent potentials fitting the Granada-2013 database and about 1σ with the historical set of 13 high-quality potentials developed since the 1993 Nijmegen analysis.

  10. The phenomenology of the psychotic break and Huxley's trip: substance use and the onset of psychosis.

    PubMed

    Nelson, Barnaby; Sass, Louis A

    2008-01-01

    While considerable research attention has been devoted to the causal relationship between substance use and psychosis, the phenomenology of the association between the two has largely been ignored. This is a significant shortcoming, because it blinds researchers to the possibility that there may be elements of the subjective experience of substance use and psychosis that contribute to their apparent relationship in empirical studies. The current paper examines the phenomenology of the onset of psychosis and the phenomenology of substance intoxication through consideration of two texts: Sass's account of the phenomenology of psychosis onset and Huxley's account of the experience of hallucinogenic intoxication. Sass's account of psychosis onset includes four components: Unreality, Fragmentation, Mere Being, and Apophany. The analysis reveals significant parallels - and also some differences - between this account and the phenomenology of substance intoxication. We discuss the implications of this for the causal relationship between psychosis and substance use and suggest several ways of understanding the overlapping phenomenologies. This includes the suggestion of a shared factor, perhaps best described as psychotic-like experience, which seems to involve a breakdown of the sign-referent relationship and relationship with the common-sense, practical world. However, in the onset of psychosis, this breakdown is primarily experienced as a sense of alienation from self and world, whereas in the hallucinogenic state a sense of mystical union and revelation seems predominant. Further research may extend this analysis by looking at experiences with other drugs, particularly cannabis, and by examining the phenomenology of psychotic disorder beyond the first episode.

    2015-11-01

    In materials science and many other research areas, models are frequently inferred without considering their generalization to unseen data. We apply statistical learning using cross-validation to obtain an optimally predictive coarse-grained description of a two-dimensional kinetic nearest-neighbor Ising model with Glauber dynamics (GD) based on the stochastic Ginzburg-Landau equation (sGLE). The latter is learned from GD "training" data using a log-likelihood analysis, and its predictive ability for various complexities of the model is tested on GD "test" data independent of the data used to train the model on. Using two different error metrics, we perform a detailed analysis of the error between magnetization time trajectories simulated using the learned sGLE coarse-grained description and those obtained using the GD model. We show that both for equilibrium and out-of-equilibrium GD training trajectories, the standard phenomenological description using a quartic free energy does not always yield the most predictive coarse-grained model. Moreover, increasing the amount of training data can shift the optimal model complexity to higher values. Our results are promising in that they pave the way for the use of statistical learning as a general tool for materials modeling and discovery.

    Phenomenological models that invoke catalyst sites with different adsorption constants and rate constants are well-established, but computational and experimental methods are just beginning to provide atomically resolved details about amorphous surfaces and their active sites. This letter develops a statistical transformation from the quenched disorder distribution of site structures to the distribution of activation energies for sites on amorphous supports. We show that the overall kinetics are highly sensitive to the precise nature of the low energy tail in the activation energy distribution. Our analysis motivates further development of systematic methods to identify and understand the most reactive members of the active site distribution.

    PubMed

    Gustin, Lena Wiklund

    2017-08-01

    The purpose of this article is to reflect on being mindful as a phenomenological attitude rather than on describing mindfulness as a therapeutic intervention. I will also explore the possibilities that being mindful might open up in relation to nursing research and holistic nursing. I will describe and interpret mindfulness as a state of being by means of van Manen's phenomenological method, using the language of phenomenology rather than the language of reductionist science. Thus, this article can be considered a reflective narrative, describing both the process of orienting to the phenomenon, making preunderstandings-including own experiences of mindfulness-visible, and a thematic analysis of nine scientific articles describing the phenomenon. Being mindful as a phenomenological attitude can be described as a deliberate intentionality, where the person is present in the moment and open to what is going on, bridling personal values and accepting the unfamiliar, thus achieving a sense of being peacefully situated in the world, and able to apprehend one's being-in-the-world. Being mindful as a phenomenological attitude can contribute not only to phenomenological nursing research but also support nurses' presence and awareness.

  5. Statistical physics approach to earthquake occurrence and forecasting

    NASA Astrophysics Data System (ADS)

    de Arcangelis, Lucilla; Godano, Cataldo; Grasso, Jean Robert; Lippiello, Eugenio

    2016-04-01

    There is striking evidence that the dynamics of the Earth crust is controlled by a wide variety of mutually dependent mechanisms acting at different spatial and temporal scales. The interplay of these mechanisms produces instabilities in the stress field, leading to abrupt energy releases, i.e., earthquakes. As a consequence, the evolution towards instability before a single event is very difficult to monitor. On the other hand, collective behavior in stress transfer and relaxation within the Earth crust leads to emergent properties described by stable phenomenological laws for a population of many earthquakes in size, time and space domains. This observation has stimulated a statistical mechanics approach to earthquake occurrence, applying ideas and methods as scaling laws, universality, fractal dimension, renormalization group, to characterize the physics of earthquakes. In this review we first present a description of the phenomenological laws of earthquake occurrence which represent the frame of reference for a variety of statistical mechanical models, ranging from the spring-block to more complex fault models. Next, we discuss the problem of seismic forecasting in the general framework of stochastic processes, where seismic occurrence can be described as a branching process implementing space-time-energy correlations between earthquakes. In this context we show how correlations originate from dynamical scaling relations between time and energy, able to account for universality and provide a unifying description for the phenomenological power laws. Then we discuss how branching models can be implemented to forecast the temporal evolution of the earthquake occurrence probability and allow to discriminate among different physical mechanisms responsible for earthquake triggering. In particular, the forecasting problem will be presented in a rigorous mathematical framework, discussing the relevance of the processes acting at different temporal scales for different levels of prediction. In this review we also briefly discuss how the statistical mechanics approach can be applied to non-tectonic earthquakes and to other natural stochastic processes, such as volcanic eruptions and solar flares.

    The phenomenological approach has a quasi-monopoly in the individual and subjectivity analyses in social sciences. However, the conceptual apparatus associated with this approach is very restrictive. The human being has to be understood as rational, conscious, intentional, interested, and autonomous. Because of this, a large dimension of human activity cannot be taken into consideration: all that does not fit into the analytical categories (nonrational, nonconscious, etc.). Moreover, this approach cannot really move toward a relational analysis unless it is between individuals predefined by its conceptual apparatus. This lack of complexity makes difficult the establishment of links between phenomenology and systemic analysis in which relation (and its derivatives such as recursiveness, dialectic, correlation) plays an essential role. This article intends to propose a way for systemic analysis to apprehend the individual with respect to his complexity.

    Background: Authors of the Diagnostic and Statistical Manual, Fifth Edition (DSM-V) have recommended to “integrate dimensions into clinical practice.” The epidemiology and associated phenomenology of formal thought disorder (FTD) have been described but not reviewed. We aimed to carry out a systematic review of FTD to this end. Methods: A systematic review of FTD literature, from 1978 to 2013, using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Results: A total of 881 abstracts were reviewed and 120 articles met inclusion criteria; articles describing FTD factor structure (n = 15), prevalence and longitudinal course (n = 41), role in diagnosis (n = 22), associated clinical variables (n = 56), and influence on outcome (n = 35) were included. Prevalence estimates for FTD in psychosis range from 5% to 91%. Dividing FTD into domains, by factor analysis, can accurately identify 91% of psychotic diagnoses. FTD is associated with increased clinical severity. Poorer outcomes are predicted by negative thought disorder, more so than the typical construct of “disorganized speech.” Conclusion: FTD is a common symptom of psychosis and may be considered a marker of illness severity. Detailed dimensional assessment of FTD can clarify diagnosis and may help predict prognosis. PMID:25180313

  10. [Rating scales based on the phenomenological and structural approach].

    PubMed

    Schiltz, L

    2006-01-01

    A current tendency of research in clinical psychology consists in using an integrated quantitative and qualitative methodology. This approach is especially suited to the study of the therapeutic intervention where the researcher is himself part of the situation he is investigating. As to the tools of research, the combination of the semi-structured clinical interview, of psychometric scales and projective tests has proved to be pertinent to describe the multidimensional and fluctuating reality of the therapeutic relationship and the changes induced by it in the two partners. In arts therapeutic research the investigation of the artistic production or of the free expression of people may complete the psychometric and projective tools. The concept of "expressive test" is currently being used to characterise this method. In this context, the development of rating scales, based on the phenomenological and structural or holistic approach allows us making the link between qualitative analysis and quantification, leading to the use of inferential statistics, providing that we remain at the nominal or ordinal level of measurement. We are explaining the principle of construction of these rating scales and we are illustrating our practice with some examples drawn from studies we realized in clinical psychology.

    The life-review experience (LRE) is a most intriguing mental phenomenon that fascinated humans from time immemorial. In LRE one sees vividly a succession of one's own life-events. While reports of LRE are abundant in the medical, psychological and popular literature, not much is known about LRE's cognitive and psychological basis. Moreover, while LRE is known as part of the phenomenology of near-death experience, its manifestation in the general population and in other circumstances is still to be investigated. In a first step we studied the phenomenology of LRE by means of in-depth qualitative interview of 7 people who underwent full LRE. In a second step we extracted the main characters of LRE, to develop a questionnaire and an LRE-score that best reflects LRE phenomenology. This questionnaire was then run on 264 participants of diverse ages and backgrounds, and the resulted score was further subjected to statistical analyses. Qualitative analysis showed the LRE to manifest several subtypes of characteristics in terms of order, continuity, the covered period, extension to the future, valence, emotions, and perspective taking. Quantitative results in the normal population showed normal distribution of the LRE-score over participants. Re-experiencing one's own life-events, so-called LRE, is a phenomenon with well-defined characteristics, and its subcomponents may be also evident in healthy people. This suggests that a representation of life-events as a continuum exists in the cognitive system, and maybe further expressed in extreme conditions of psychological and physiological stress.

  14. Non-extensivity and complexity in the earthquake activity at the West Corinth rift (Greece)

    2013-04-01

    Earthquakes exhibit complex phenomenology that is revealed from the fractal structure in space, time and magnitude. For that reason other tools rather than the simple Poissonian statistics seem more appropriate to describe the statistical properties of the phenomenon. Here we use Non-Extensive Statistical Physics [NESP] to investigate the inter-event time distribution of the earthquake activity at the west Corinth rift (central Greece). This area is one of the most seismotectonically active areas in Europe, with an important continental N-S extension and high seismicity rates. NESP concept refers to the non-additive Tsallis entropy Sq that includes Boltzmann-Gibbs entropy as a particular case. This concept has been successfully used for the analysis of a variety of complex dynamic systems including earthquakes, where fractality and long-range interactions are important. The analysis indicates that the cumulative inter-event time distribution can be successfully described with NESP, implying the complexity that characterizes the temporal occurrences of earthquakes. Further on, we use the Tsallis entropy (Sq) and the Fischer Information Measure (FIM) to investigate the complexity that characterizes the inter-event time distribution through different time windows along the evolution of the seismic activity at the West Corinth rift. The results of this analysis reveal a different level of organization and clusterization of the seismic activity in time. Acknowledgments.

  15. Aging in the Shadow of Violence: A Phenomenological Conceptual Framework for Understanding Elderly Women Who Experienced Lifelong IPV.

    PubMed

    Band-Winterstein, Tova

    2015-01-01

    This article suggests a heuristic framework for understanding elderly women's "lived experience" of lifelong intimate partner violence (IPV). This framework is based on the phenomenological qualitative studies of 31 women, aged 60-83, using a semistructured interview guide. From the results, a matrix emerged built on two axes. The first axis consists of three phenomenological dimensions: suffering, a "ticking clock," and life wisdom. The second axis consists of four themes that emerged from the content analysis: loneliness, regret, being in a state of waiting, and being a living monument to perpetual victimhood. The practical implications of these phenomenological findings are then discussed.

  16. Unspoken phenomena: using the photovoice method to enrich phenomenological inquiry.

    2013-06-01

    Photovoice is a powerful method that is gaining momentum in nursing research. As a relatively new method in nursing science, the situatedness of photovoice within or alongside various research methodologies in a single study remains in a stage of early development. The purpose of this paper is to discuss the photovoice method as a means to elicit phenomenological data when researching the lived experience. While the foundational bases of phenomenology and photovoice differ substantially, the argument presented in this paper suggests that the photovoice method can be successfully used in phenomenological inquiry provided that significant rigour checks are pursued. This includes reflecting upon the origins and understandings of both methodology and method to promote methodological congruency. Data collection and analysis approaches that contribute to phenomenological inquiry using the photovoice method in addition to rigour and ethical considerations are discussed. The use of data generated from photovoice in phenomenological inquiry may fill a void of understanding furnished by limitations of traditional phenomenological inquiry and of spoken language and can enhance understanding of the lived experience, which may not always be best understood by words alone. © 2012 John Wiley & Sons Ltd.

    1979-01-01

    Cumulative rain fade statistics are used by space communications engineers to establish transmitter power and receiver sensitivities for systems operating under various geometries, climates, and radio frequencies. Space-diversity performance criteria are also of interest. This work represents a review, in which are examined the many elements involved in the employment of single nonattenuating frequency radars for arriving at the desired information. The elements examined include radar techniques and requirements, phenomenological assumptions, path attenuation formulations and procedures, as well as error budgeting and calibration analysis. Included are the pertinent results of previous investigators who have used radar for rain-attenuation modeling. Suggestions are made for improving present methods.

    2017-01-01

    It is critical for psychiatry as a field to develop approaches to define the molecular, cellular, and circuit basis of its brain diseases, especially for serious mental illnesses, and then to use these definitions to generate biologically based disease categories, as well as to explore disease mechanisms and illness etiologies. Our current reliance on phenomenology is inadequate to support exploration of molecular treatment targets and disease formulations, and the leap directly from phenomenology to disease biology has been limiting because of broad heterogeneity within conventional diagnoses. The questions addressed in this review are formulated around how we can use brain biomarkers to achieve disease categories that are biologically based. We have grouped together a series of vignettes as examples of early approaches, all using the Bipolar and Schizophrenia Network on Intermediate Phenotypes (BSNIP) biomarker database and collaborators, starting off with describing the foundational statistical methods for these goals. We use primarily criterion-free statistics to identify pertinent groups of involved genes related to psychosis as well as symptoms, and finally, to create new biologically based disease cohorts within the psychopathological dimension of psychosis. Although we do not put these results forward as final formulations, they represent a novel effort to rely minimally on phenomenology as a diagnostic tool and to fully embrace brain characteristics of structure, as well as molecular and cellular characteristics and function, to support disease definition in psychosis.

  9. Seeing number using texture: How summary statistics account for reductions in perceived numerosity in the visual periphery.

    PubMed

    Balas, Benjamin

    2016-11-01

    Peripheral visual perception is characterized by reduced information about appearance due to constraints on how image structure is represented. Visual crowding is a consequence of excessive integration in the visual periphery. Basic phenomenology of visual crowding and other tasks have been successfully accounted for by a summary-statistic model of pooling, suggesting that texture-like processing is useful for how information is reduced in peripheral vision. I attempt to extend the scope of this model by examining a property of peripheral vision: reduced perceived numerosity in the periphery. I demonstrate that a summary-statistic model of peripheral appearance accounts for reduced numerosity in peripherally viewed arrays of randomly placed dots, but does not account for observed effects of dot clustering within such arrays. The model thus offers a limited account of how numerosity is perceived in the visual periphery. I also demonstrate that the model predicts that numerosity estimation is sensitive to element shape, which represents a novel prediction regarding the phenomenology of peripheral numerosity perception. Finally, I discuss ways to extend the model to a broader range of behavior and the potential for using the model to make further predictions about how number is perceived in untested scenarios in peripheral vision.

  10. A method for phenomenological analysis of ecological data.

    NASA Technical Reports Server (NTRS)

    Huang, H.-W.; Morowitz, H. J.

    1972-01-01

    The experimental meaning of the phenomenological differential equations for a competing population is reviewed. It is concluded that it is virtually impossible to construct the differential equations precise enough for studying stability. We consider instead a method of phenomenological analysis which can be applied to a set of population curves. We suggest an ecological index calculated from the population curves, which indicates a group property of the entire system. As a function of time, the index is presumably insensitive to Volterra type fluctuations. A marked increase of the index's value however indicates a marked change of the environmental conditions. It is not easy to deduce the group property from the population curves alone, because a change in population is in general due to the superposition of external disturbances and Volterra fluctuations.

    Flessner, Christopher A; Woods, Douglas W

    2006-11-01

    In this study, the authors collected data on the demographic characteristics, phenomenology, and social and economic impact of skin picking. A total of 92 participants completed an anonymous, Internet-based survey through a link to the Trichotillomania Learning Center's home page. Results indicated that skin pickers experienced social, occupational, and academic impairment, a number of medical or mental health concerns, and financial burdens, which they attributed to skin picking. Results also revealed moderate, statistically significant relationships between skin picking severity and symptoms of depression, anxiety, and experiential avoidance. Subsequent mediational analyses demonstrated that the relationship between skin picking severity and symptoms of anxiety and depression was partially mediated by experiential avoidance. Implications, conclusions, and future areas of research are discussed.

    Phenomenology is a useful methodological approach in qualitative nursing research. It enables researchers to put aside their perceptions of a phenomenon and give meaning to a participant's experiences. Exploring the experiences of others enables previously unavailable insights to be discovered. To delineate the implementation of Colaizzi's ( 1978 ) method of data analysis in descriptive phenomenological nursing research. The use of Colaizzi's method of data analysis enabled new knowledge to be revealed and provided insights into the experiences of nurse academics teaching on satellite campuses. Local adaptation of the nursing curriculum and additional unnoticed responsibilities had not been identified previously and warrant further research. Colaizzi's ( 1978 ) method of data analysis is rigorous and robust, and therefore a qualitative method that ensures the credibility and reliability of its results. It allows researchers to reveal emergent themes and their interwoven relationships. Researchers using a descriptive phenomenological approach should consider using this method as a clear and logical process through which the fundamental structure of an experience can be explored. Colaizzi's phenomenological methodology can be used reliably to understand people's experiences. This may prove beneficial in the development of therapeutic policy and the provision of patient-centred care. ©2018 RCN Publishing Company Ltd. All rights reserved.

    2010-01-01

    Nine percent of new mothers in the United States who participated in the Listening to Mothers II Postpartum Survey screened positive for meeting the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for posttraumatic stress disorder after childbirth. Women who have had a traumatic birth experience report fewer subsequent children and a longer length of time before their second baby. Childbirth-related posttraumatic stress disorder impacts couples' physical relationship, communication, conflict, emotions, and bonding with their children. The purpose of this study was to describe the meaning of women's experiences of a subsequent childbirth after a previous traumatic birth. Phenomenology was the research design used. An international sample of 35 women participated in this Internet study. Women were asked, "Please describe in as much detail as you can remember your subsequent pregnancy, labor, and delivery following your previous traumatic birth." Colaizzi's phenomenological data analysis approach was used to analyze the stories of the 35 women. Data analysis yielded four themes: (a) riding the turbulent wave of panic during pregnancy; (b) strategizing: attempts to reclaim their body and complete the journey to motherhood; (c) bringing reverence to the birthing process and empowering women; and (d) still elusive: the longed-for healing birth experience. Subsequent childbirth after a previous birth trauma has the potential to either heal or retraumatize women. During pregnancy, women need permission and encouragement to grieve their prior traumatic births to help remove the burden of their invisible pain.

    2011-06-01

    Our aim was to develop a clinimetric scale evaluating motor phenomena, associated features, and severity of psychogenic nonepileptic seizures (PNES). Sixty video/EEG-recorded PNES induced by suggestion maneuvers were evaluated. We examined the relationship between results from this scale and results from the Clinical Global Impression (CGI) scale to validate this technique. Interrater reliabilities of the PNES scale for three raters were analyzed using the AC1 statistic, Kendall's coefficient of concordance (KCC), and intraclass correlation coefficients (ICCs). The relationship between the CGI and PNES scales was evaluated with Spearman correlations. The AC1 statistic demonstrated good interrater reliability for each phenomenon analyzed (tremor/oscillation, tonic; clonic/jerking, hypermotor/agitation, atonic/akinetic, automatisms, associated features). KCC and the ICC showed moderate interrater agreement for phenomenology, associated phenomena, and total PNES scores. Spearman's correlation of mean CGI score with mean total PNES score was 0.69 (P<0.001). The scale described here accurately evaluates the phenomenology of PNES and could be used to assess and compare subgroups of patients with PNES. Copyright © 2011 Elsevier Inc. All rights reserved.

  17. Chapter 3 – Phenomenology of Tsunamis: Statistical Properties from Generation to Runup

    USGS Publications Warehouse

    Geist, Eric L.

    2015-01-01

    Observations related to tsunami generation, propagation, and runup are reviewed and described in a phenomenological framework. In the three coastal regimes considered (near-field broadside, near-field oblique, and far field), the observed maximum wave amplitude is associated with different parts of the tsunami wavefield. The maximum amplitude in the near-field broadside regime is most often associated with the direct arrival from the source, whereas in the near-field oblique regime, the maximum amplitude is most often associated with the propagation of edge waves. In the far field, the maximum amplitude is most often caused by the interaction of the tsunami coda that develops during basin-wide propagation and the nearshore response, including the excitation of edge waves, shelf modes, and resonance. Statistical distributions that describe tsunami observations are also reviewed, both in terms of spatial distributions, such as coseismic slip on the fault plane and near-field runup, and temporal distributions, such as wave amplitudes in the far field. In each case, fundamental theories of tsunami physics are heuristically used to explain the observations.

    In order to establish transmitter power and receiver sensitivity levels at frequencies above 10 GHz, the designers of earth-satellite telecommunication systems are interested in cumulative rain fade statistics at variable path orientations, elevation angles, climatological regions, and frequencies. They are also interested in establishing optimum space diversity performance parameters. In this work are examined the many elements involved in the employment of single non-attenuating frequency radars for arriving at the desired information. The elements examined include radar techniques and requirements, phenomenological assumptions, path attenation formulations and procedures, as well as error budgeting and calibration analysis. Included are the pertinent results of previous investigators who have used radar for rain attenuation modeling. Suggestions are made for improving present methods.

    1989-01-01

    Ceramic matrix composites offer significant potential for improving the performance of turbine engines. In order to achieve their potential, however, improvements in design methodology are needed. In the past most components using structural ceramic matrix composites were designed by trial and error since the emphasis of feasibility demonstration minimized the development of mathematical models. To understand the key parameters controlling response and the mechanics of failure, the development of structural failure models is required. A review of short term failure models with potential for ceramic matrix composite laminates under monotonic loads is presented. Phenomenological, semi-empirical, shear-lag, fracture mechanics, damage mechanics, and statistical models for the fast fracture analysis of continuous fiber unidirectional ceramic matrix composites under monotonic loads are surveyed.

  8. “Stringy” coherent states inspired by generalized uncertainty principle

    Coherent States with Fractional Revival property, that explicitly satisfy the Generalized Uncertainty Principle (GUP), have been constructed in the context of Generalized Harmonic Oscillator. The existence of such states is essential in motivating the GUP based phenomenological results present in the literature which otherwise would be of purely academic interest. The effective phase space is Non-Canonical (or Non-Commutative in popular terminology). Our results have a smooth commutative limit, equivalent to Heisenberg Uncertainty Principle. The Fractional Revival time analysis yields an independent bound on the GUP parameter. Using this and similar bounds obtained here, we derive the largest possible value of the (GUP induced) minimum length scale. Mandel parameter analysis shows that the statistics is Sub-Poissonian. Correspondence Principle is deformed in an interesting way. Our computational scheme is very simple as it requires only first order corrected energy values and undeformed basis states.

  9. A mathematical model to describe the nonlinear elastic properties of the gastrocnemius tendon of chickens.

    Foutz, T L

    1991-03-01

    A phenomenological model was developed to describe the nonlinear elastic behavior of the avian gastrocnemius tendon. Quasistatic uniaxial tensile tests were used to apply a deformation and resulting load on the tendon at a deformation rate of 5 mm/min. Plots of deformation versus load indicated a nonlinear loading response. By calculating engineering stress and engineering strain, the experimental data were normalized for tendon shape. The elastic response was determined from stress-strain curves and was found to vary with engineering strain. The response to the applied engineering strain could best be described by a mathematical model that combined a linear function and a nonlinear function. Three parameters in the model were developed to represent the nonlinear elastic behavior of the tendon, thereby allowing analysis of elasticity without prior knowledge of engineering strain. This procedure reduced the amount of data needed for the statistical analysis of nonlinear elasticity.

    2018-03-01

    Some couples find in infertility the bonding opportunities that reinforce their relationship. Using an interpretative phenomenological analysis, this study examined marital benefits in three couples seeking fertility treatment. Interviews revealed five types of benefits: being engaged in a shared hardship, feeling closer to one another, feeling reassured in the relationship, developing a satisfying communication and support behaviors, and having faith in the couple's capacity to face adversity. A dyadic analysis also illustrated how marital benefits developed in each couple. Marital benefits nourished marital satisfaction, thus underscoring their importance to help couples cope through fertility treatment.

    2014-01-01

    A comprehensive understanding of the phenomenology of auditory hallucinations (AHs) is essential for developing accurate models of their causes. Yet, only 1 detailed study of the phenomenology of AHs with a sample size of N ≥ 100 has been published. The potential for overreliance on these findings, coupled with a lack of phenomenological research into many aspects of AHs relevant to contemporary neurocognitive models and the proposed (but largely untested) existence of AH subtypes, necessitates further research in this area. We undertook the most comprehensive phenomenological study of AHs to date in a psychiatric population (N = 199; 81% people diagnosed with schizophrenia), using a structured interview schedule. Previous phenomenological findings were only partially replicated. New findings included that 39% of participants reported that their voices seemed in some way to be replays of memories of previous conversations they had experienced; 45% reported that the general theme or content of what the voices said was always the same; and 55% said new voices had the same content/theme as previous voices. Cluster analysis, by variable, suggested the existence of 4 AH subtypes. We propose that there are likely to be different neurocognitive processes underpinning these experiences, necessitating revised AH models. PMID:23267192

    2015-01-01

    To evaluate the importance of phenomenological aspects of the cognitive rumination (CR) construct in current empirical psychiatric research. We searched SciELO, Scopus, ScienceDirect, MEDLINE, OneFile (GALE), SpringerLink, Cambridge Journals and Web of Science between February and March of 2014 for studies whose title and topic included the following keywords: cognitive rumination; rumination response scale; and self-reflection. The inclusion criteria were: empirical clinical study; CR as the main object of investigation; and study that included a conceptual definition of CR. The studies selected were published in English in biomedical journals in the last 10 years. Our phenomenological analysis was based on Karl Jaspers' General Psychopathology. Most current empirical studies adopt phenomenological cognitive elements in conceptual definitions. However, these elements do not seem to be carefully examined and are indistinctly understood as objective empirical factors that may be measured, which may contribute to misunderstandings about CR, erroneous interpretations of results and problematic theoretical models. Empirical studies fail when evaluating phenomenological aspects of the cognitive elements of the CR construct. Psychopathology and phenomenology may help define the characteristics of CR elements and may contribute to their understanding and hierarchical organization as a construct. A review of the psychopathology principles established by Jasper may clarify some of these issues.

  7. Toward a Phenomenological Account of Embodied Subjectivity in Autism.

    PubMed

    Boldsen, Sofie

    2018-06-18

    Sensorimotor research is currently challenging the dominant understanding of autism as a deficit in the cognitive ability to 'mindread'. This marks an emerging shift in autism research from a focus on the structure and processes of the mind to a focus on autistic behavior as grounded in the body. Contemporary researchers in sensorimotor differences in autism call for a reconciliation between the scientific understanding of autism and the first-person experience of autistic individuals. I argue that fulfilling this ambition requires a phenomenological understanding of the body as it presents itself in ordinary experience, namely as the subject of experience rather than a physical object. On this basis, I investigate how the phenomenology of Maurice Merleau-Ponty can be employed as a frame of understanding for bodily experience in autism. Through a phenomenological analysis of Tito Mukhopadhyay's autobiographical work, How can I talk if my lips don't move (2009), I illustrate the relevance and potential of phenomenological philosophy in autism research, arguing that this approach enables a deeper understanding of bodily and subjective experiences related to autism.

    2006-05-01

    The subject of euthanasia divides both people and nations. It will always continue to do so because the arguments for and against this issue are intrinsically related to each other. This paper offers an analysis of the interrelation of the arguments, departing from a phenomenology of boundaries. From the participant perspective the boundary of euthanasia appears as a limit. From a helicopter perspective it appears as a border. Reflecting on both perspectives they turn out to complement each other: the positive effects of the former correspond to the negative effects of the latter. In order to see how this interrelation of viewpoints works out in the case of euthanasia a paradigmatic case is analysed from the perspective of the patient, the doctor, and the family. This phenomenological analysis does not directly lead to normative conclusions. It helps by both paying attention to, and dealing with, the complexity of the issue with intellectual honesty.

    2017-10-01

    A body of research suggests compromise of autobiographical memory in Korsakoff's syndrome (KS). The present paper extends this literature by investigating the subjective experience of autobiographical recall in the syndrome. Patients with KS and controls were asked to retrieve autobiographical memories. After memory retrieval, participants were asked to rate phenomenological characteristics of their memories (i.e., reliving, back in time, remembering, realness, visual imagery, auditory imagery, language, emotion, rehearsal, importance, spatial recall and temporal recall). Analysis showed lower "Mean Phenomenological Experience" in the Korsakoff patients than in controls. However, the Korsakoff patients attributed relatively high emotional value and importance to their memories. Although our findings suggest compromised phenomenological reliving of autobiographical memory in patients with KS, affective characteristics such as emotion and importance are likely to play a main role in the subjective experience of the past in these patients.

    PubMed

    2015-09-01

    Cognitive control is accompanied by observable negative affect. But how is this negative affect experienced subjectively, and are these feelings related to variation in cognitive control? To address these questions, 42 participants performed a punished inhibitory control task while periodically reporting their subjective experience. We found that within-subject variation in subjective experience predicted control implementation, but not neural monitoring (i.e., the error-related negativity, ERN). Specifically, anxiety and frustration predicted increased and decreased response caution, respectively, while hopelessness accompanied reduced inhibitory control, and subjective effort coincided with the increased ability to inhibit prepotent responses. Clarifying the nature of these phenomenological results, the effects of frustration, effort, and hopelessness-but not anxiety-were statistically independent from the punishment manipulation. Conversely, while the ERN was increased by punishment, the lack of association between this component and phenomenology suggests that early monitoring signals might precede the development of control-related subjective experience. Our results indicate that the types of feelings experienced during cognitively demanding tasks are related to different aspects of controlled performance, critically suggesting that the relationship between emotion and cognitive control extends beyond the dimension of valence. © 2015 Society for Psychophysiological Research.

    I have sometimes thought that what makes a man's work classic is often just this multiplicity [of interpretations], which invites and at the same time resists our craving for a clear understanding. Wright (1982, p. 34), on Wittgenstein's philosophy Small-scale turbulence has been an area of especially active research in the recent past, and several useful research directions have been pursued. Here, we selectively review this work. The emphasis is on scaling phenomenology and kinematics of small-scale structure. After providing a brief introduction to the classical notions of universality due to Kolmogorov and others, we survey the existing work on intermittency, refined similarity hypotheses, anomalous scaling exponents, derivative statistics, intermittency models, and the structure and kinematics of small-scale structure - the latter aspect coming largely from the direct numerical simulation of homogeneous turbulence in a periodic box.

  19. Phenomenology as a resource for patients.

    PubMed

    Carel, Havi

    2012-04-01

    Patient support tools have drawn on a variety of disciplines, including psychotherapy, social psychology, and social care. One discipline that has not so far been used to support patients is philosophy. This paper proposes that a particular philosophical approach, phenomenology, could prove useful for patients, giving them tools to reflect on and expand their understanding of their illness. I present a framework for a resource that could help patients to philosophically examine their illness, its impact on their life, and its meaning. I explain the need for such a resource, provide philosophical grounding for it, and outline the epistemic and existential gains philosophy offers. Illness often begins as an intrusion on one's life but with time becomes a way of being. I argue that this transition impacts on core human features such as the experience of space and time, human abilities, and adaptability. It therefore requires philosophical analysis and response. The paper uses ideas from Husserl and Merleau-Ponty to present such a response in the form of a phenomenological toolkit for patients. The toolkit includes viewing illness as a form of phenomenological reduction, thematizing illness, and examining illness as altering the ill person's being in the world. I suggest that this toolkit could be offered to patients as a workshop, using phenomenological concepts, texts, and film clips to reflect on illness. I conclude by arguing that examining illness as a limit case of embodied existence deepens our understanding of phenomenology.

    Although there are an increasing number of qualitative studies investigating the benefits of music therapy interventions in cancer care settings, few studies have adopted a phenomenological approach to explore how and why such interventions work. The aim of this study was to explore the psychological processes involved in an improvisational music therapy program for cancer patients. Nine individuals took part in an improvisational music therapy program and participated in semi-structured interviews. Interpretative Phenomenological Analysis (IPA) was employed as a theoretical and methodological framework for the analysis of the interviews. Recurrent themes revealed a variety of social and psychological benefits related to the experience of music therapy, such as facilitating peer support and group interaction, increasing self-confidence, relaxation, the generation of positive feelings, stress relief and feelings of enhanced communication through music. There was also an emphasis upon the importance of social interaction and communication. This paper highlights a number of key benefits connected with music therapy for patients with cancer and the effectiveness of IPA in applied health psychology research.

    Elastic and inelastic proton scattering has been measured in inverse kinematics on the unstable nucleus 40S. A phenomenological distorted wave Born approximation analysis yields a quadrupole deformation parameter β2=0.35+/-0.05 for the 2+1 state. Consistent phenomenological and microscopic proton scattering analyses have been applied to all even-even sulfur isotopes from A=32 to A=40. The second analysis used microscopic collective model densities and a modified Jeukenne-Lejeune-Mahaux nucleon-nucleon effective interaction. This microscopic analysis suggests the presence of a neutron skin in the heavy sulfur isotopes. The analysis is consistent with normalization values for λv and λw of 0.95 for both the real and imaginary parts of the Jeukenne-Lejeune-Mahaux potential.

    The Schrödinger–Langevin equation (SLE) is considered as an effective open quantum system formalism suitable for phenomenological applications involving a quantum subsystem interacting with a thermal bath. We focus on two open issues relative to its solutions: the stationarity of the excited states of the non-interacting subsystem when one considers the dissipation only and the thermal relaxation toward asymptotic distributions with the additional stochastic term. We first show that a proper application of the Madelung/polar transformation of the wave function leads to a non zero damping of the excited states of the quantum subsystem. We then study analytically and numerically themore » SLE ability to bring a quantum subsystem to the thermal equilibrium of statistical mechanics. To do so, concepts about statistical mixed states and quantum noises are discussed and a detailed analysis is carried with two kinds of noise and potential. We show that within our assumptions the use of the SLE as an effective open quantum system formalism is possible and discuss some of its limitations.« less

    Turbulence is ubiquitous in plasmas, leading to rich dynamics characterized by irregularity, irreversibility, energy fluctuations across many scales, and energy transfer across many scales. Another fundamental and generic feature of turbulence, although sometimes overlooked, is the inhomogeneous dissipation of energy in space and in time. This is a consequence of intermittency, the scale-dependent inhomogeneity of dynamics caused by fluctuations in the turbulent cascade. Intermittency causes turbulent plasmas to self-organize into coherent dissipative structures, which may govern heating, diffusion, particle acceleration, and radiation emissions. In this paper, we present recent progress on understanding intermittency in incompressible magnetohydrodynamic turbulence with a strongmore » guide field. We focus on the statistical analysis of intermittent dissipative structures, which occupy a small fraction of the volume but arguably account for the majority of energy dissipation. We show that, in our numerical simulations, intermittent structures in the current density, vorticity, and Elsässer vorticities all have nearly identical statistical properties. We propose phenomenological explanations for the scalings based on general considerations of Elsässer vorticity structures. Finally, we examine the broader implications of intermittency for astrophysical systems.« less

    The diagnostic criteria for the attentional deficit hyperactivity disorder (ADHD), were defined by the American Psychiatric Association in the Diagnostic and Statistical Manual of Mental Disorders fourth version (DSM-IV) and World Health Organization in the ICD-10. The American Psychiatric Association used an internal validity analysis to select specific behavioral symptoms associated with the disorder and to build five cross-cultural criteria for its use in the categorical diagnosis. The DSM has been utilized for clinicians and researchers as a valid and stable approach since 1968. We did a systematic review of scientific literature in Spanish and English, aimed to identify the historical origin that supports ADHD as a psychiatric construct. This comprehensive review started exploring the concept of minimal brain dysfunction, hyper-activity, inattention, impulsivity since 1932 to 2011. This paper summarize all the DSM versions that include the definition of ADHD or its equivalent, and it point out the statistical and methodological approach implemented for defining ADHD as a valid epidemiological and psychometric construct. Finally the paper discusses some considerations and suggestions for the new versions of the manual.

    We perform a definitive analysis of Bianchi VIIh cosmologies with Wilkinson Microwave Anisotropy Probe (WMAP) observations of the cosmic microwave background (CMB) temperature anisotropies. Bayesian analysis techniques are developed to study anisotropic cosmologies using full-sky and partial-sky masked CMB temperature data. We apply these techniques to analyse the full-sky internal linear combination (ILC) map and a partial-sky masked W-band map of WMAP 9 yr observations. In addition to the physically motivated Bianchi VIIh model, we examine phenomenological models considered in previous studies, in which the Bianchi VIIh parameters are decoupled from the standard cosmological parameters. In the two phenomenological models considered, Bayes factors of 1.7 and 1.1 units of log-evidence favouring a Bianchi component are found in full-sky ILC data. The corresponding best-fitting Bianchi maps recovered are similar for both phenomenological models and are very close to those found in previous studies using earlier WMAP data releases. However, no evidence for a phenomenological Bianchi component is found in the partial-sky W-band data. In the physical Bianchi VIIh model, we find no evidence for a Bianchi component: WMAP data thus do not favour Bianchi VIIh cosmologies over the standard Λ cold dark matter (ΛCDM) cosmology. It is not possible to discount Bianchi VIIh cosmologies in favour of ΛCDM completely, but we are able to constrain the vorticity of physical Bianchi VIIh cosmologies at (ω/H)0 < 8.6 × 10-10 with 95 per cent confidence.

  6. Meaning, lived experience, empathy and boredom: Max van Manen on phenomenology and Heidegger.

    PubMed

    Paley, John

    2018-07-01

    Phenomenology as Qualitative Research: A Critical Analysis of Meaning Attribution has attracted the attention of Max van Manen, who has published a highly critical review article. Anyone reading this article, but unfamiliar with the book, will get a distorted view of what it is about, whom it is addressed to, what it tries to achieve, and how it goes about presenting its arguments. Not mildly distorted, in need of the odd correction here and there, but systematically misrepresented. One problem is that van Manen appears to have an idée fixe which prevents him from recognizing that the book is not about a certain philosophical tradition (known as "phenomenology"), but about a particular type of qualitative research (also known, unfortunately and confusingly, as "phenomenology"). A second idée fixe disposes him to misread an earlier article of mine and (much more seriously) three works by Heidegger. My aim in this article is to describe these two idées fixes, and exhibit their consequences. In doing so, I will examine what van Manen has to say on four crucial topics: meaning, lived experience, empathy, and Heidegger's analysis of boredom in The Fundamental Concepts of Metaphysics. © 2018 John Wiley & Sons Ltd.

    The "Photochemical Phenomenology Model for the New Millennium" project tackles the issue of reengineering and extension of validated physics-based modeling capabilities ("legacy" computer codes) to application-oriented software for use in science and science-support activities. While the design and architecture layouts are in terms of general particle distributions involved in scattering, impact, and reactive interactions, initial Photochemical Phenomenology Modeling Tool (PPMT) implementations are aimed at construction and evaluation of photochemical transport models with rapid execution for use in remote sensing data analysis activities in distributed systems. Current focus is on the Composite Infrared Spectrometer (CIRS) data acquired during the CASSINI flyby of Jupiter. Overall, the project has stayed on the development track outlined in the Year 1 annual report and most Year 2 goals have been met. The issues that have required the most attention are: implementation of the core photochemistry algorithms; implementation of a functional Java Graphical User Interface; completion of a functional CORBA Component Model framework; and assessment of performance issues. Specific accomplishments and the difficulties encountered are summarized in this report. Work to be carried out in the next year center on: completion of testing of the initial operational implementation; its application to analysis of the CASSINI/CIRS Jovian flyby data; extension of the PPMT to incorporate additional phenomenology algorithms; and delivery of a mature operational implementation.

    With a substantial number of individuals diagnosed with Hand-Arm Vibration Syndrome (HAVS) and the preponderance of research focused on the medical and paramedical issues, the psychological and mental health sequelae of HAVS are largely neglected within the published literature. A series of focus groups and interviews were conducted involving nine people who had been diagnosed with HAVS. Transcripts of these interviews were analysed using Interpretative Phenomenological Analysis. Four key themes were identified within the discourse of individuals affected by HAVS: machismo; coping; psychological impacts; and the development of support services for HAVS. Clinical implications are briefly discussed.

    Micelle cluster distributions from molecular dynamics simulations of a solvent-free coarse-grained model of sodium octyl sulfate (SOS) were analyzed using an improved method to extract equilibrium association constants from small-system simulations containing one or two micelle clusters at equilibrium with free surfactants and counterions. The statistical-thermodynamic and mathematical foundations of this partition-enabled analysis of cluster histograms (PEACH) approach are presented. A dramatic reduction in computational time for analysis was achieved through a strategy similar to the selector variable method to circumvent the need for exhaustive enumeration of the possible partitions of surfactants and counterions into clusters. Using statistics from a set of small-system (up to 60 SOS molecules) simulations as input, equilibrium association constants for micelle clusters were obtained as a function of both number of surfactants and number of associated counterions through a global fitting procedure. The resulting free energies were able to accurately predict micelle size and charge distributions in a large (560 molecule) system. The evolution of micelle size and charge with SOS concentration as predicted by the PEACH-derived free energies and by a phenomenological four-parameter model fit, along with the sensitivity of these predictions to variations in cluster definitions, are analyzed and discussed.

  12. Statistical Characterization and Classification of Edge-Localized Plasma Instabilities

    2013-04-01

    The statistics of edge-localized plasma instabilities (ELMs) in toroidal magnetically confined fusion plasmas are considered. From first principles, standard experimentally motivated assumptions are shown to determine a specific probability distribution for the waiting times between ELMs: the Weibull distribution. This is confirmed empirically by a statistically rigorous comparison with a large data set from the Joint European Torus. The successful characterization of ELM waiting times enables future work to progress in various ways. Here we present a quantitative classification of ELM types, complementary to phenomenological approaches. It also informs us about the nature of ELM processes, such as whether they are random or deterministic. The methods are extremely general and can be applied to numerous other quasiperiodic intermittent phenomena.

  13. Chapter two: Phenomenology of tsunamis II: scaling, event statistics, and inter-event triggering

    Geist, Eric L.

    2012-01-01

    Observations related to tsunami catalogs are reviewed and described in a phenomenological framework. An examination of scaling relationships between earthquake size (as expressed by scalar seismic moment and mean slip) and tsunami size (as expressed by mean and maximum local run-up and maximum far-field amplitude) indicates that scaling is significant at the 95% confidence level, although there is uncertainty in how well earthquake size can predict tsunami size (R2 ~ 0.4-0.6). In examining tsunami event statistics, current methods used to estimate the size distribution of earthquakes and landslides and the inter-event time distribution of earthquakes are first reviewed. These methods are adapted to estimate the size and inter-event distribution of tsunamis at a particular recording station. Using a modified Pareto size distribution, the best-fit power-law exponents of tsunamis recorded at nine Pacific tide-gauge stations exhibit marked variation, in contrast to the approximately constant power-law exponent for inter-plate thrust earthquakes. With regard to the inter-event time distribution, significant temporal clustering of tsunami sources is demonstrated. For tsunami sources occurring in close proximity to other sources in both space and time, a physical triggering mechanism, such as static stress transfer, is a likely cause for the anomalous clustering. Mechanisms of earthquake-to-earthquake and earthquake-to-landslide triggering are reviewed. Finally, a modification of statistical branching models developed for earthquake triggering is introduced to describe triggering among tsunami sources.

    The nonlinearity of fibre-reinforced polymer (FRP) composites have significant effects on the analysis of composite structures. This article proposes a phenomenological intralaminar plasticity model to represent the nonlinearity of FRP composite materials. Based on the model presented by Ladeveze et al., the plastic potential and hardening functions are improved to give a more rational description of phenomenological nonlinearity behavior. A four-parameter hardening model is built to capture important features of the hardening curve and consequently gives the good matching of the experiments. Within the frame of plasticity theory, the detailed constitutive model, the numerical algorithm and the derivation of the tangent stiffness matrix are presented in this study to improve model robustness. This phenomenological model achieved excellent agreement between the experimental and simulation results in element scale respectively for glass fibre-reinforced polymer (GFRP) and carbon fibre-reinforced polymer (CFRP). Moreover, the model is capable of simulating the nonlinear phenomenon of laminates, and good agreement is achieved in nearly all cases.

  15. Toward a phenomenology of trance logic in posttraumatic stress disorder.

    PubMed

    Beshai, J A

    2004-04-01

    Some induction procedures result in trance logic as an essential feature of hypnosis. Trance logic is a voluntary state of acceptance of suggestions without the critical evaluation that would destroy the validity of the meaningfulness of the suggestion. Induction procedures in real and simulated conditions induce a conflict between two contradictory messages in experimental hypnosis. In military induction the conflict is much more subtle involving society's need for security and its need for ethics. Such conflicts are often construed by the subject as trance logic. Trance logic provides an opportunity for therapists using the phenomenology of "presence" to deal with the objectified concepts of "avoidance," "numbing" implicit in this kind of dysfunctional thinking in Posttraumatic Stress Disorder. An individual phenomenology of induction procedures and suggestions, which trigger trance logic, may lead to a resolution of logical fallacies and recurring painful memories. It invites a reconciliation of conflicting messages implicit in phobias and avoidance traumas. Such a phenomenological analysis of trance logic may well be a novel approach to restructure the meaning of trauma.

    2018-01-01

    The analysis of photon count data from the standard nitrogen vacancy (NV) measurement process is treated as a statistical inference problem. This has applications toward gaining better and more rigorous error bars for tasks such as parameter estimation (e.g. magnetometry), tomography, and randomized benchmarking. We start by providing a summary of the standard phenomenological model of the NV optical process in terms of Lindblad jump operators. This model is used to derive random variables describing emitted photons during measurement, to which finite visibility, dark counts, and imperfect state preparation are added. NV spin-state measurement is then stated as an abstract statistical inference problem consisting of an underlying biased coin obstructed by three Poisson rates. Relevant frequentist and Bayesian estimators are provided, discussed, and quantitatively compared. We show numerically that the risk of the maximum likelihood estimator is well approximated by the Cramér-Rao bound, for which we provide a simple formula. Of the estimators, we in particular promote the Bayes estimator, owing to its slightly better risk performance, and straightforward error propagation into more complex experiments. This is illustrated on experimental data, where quantum Hamiltonian learning is performed and cross-validated in a fully Bayesian setting, and compared to a more traditional weighted least squares fit.

    To establish the prevalence of psychological dependency in the Jamaican society in order to examine the relationship between the psychological correlates of dependency and socio-political dependency in this post-colonial country. A total of 1506 adult individuals were sampled from 2150 households using a stratified sampling method and assessed using the 17 questions of the Jamaica Personality Disorder Inventory (JPDI) on the phenomenology of dependency that are grouped into the psychological features of physiological dependency, financial dependency, and psychological dependency. The database of responses to the demographic and JPDI questionnaires was created and analysed using the Statistical Package for the Social Sciences (SPSS) version 17. Of the national population sampled, 77.1% denied having any of these phenomenological symptoms of dependence while 22.63% of the population admitted to having some phenomenology of dependency, ranging from mild (5.6%), to moderate (12.1), or severe (4.9%). Substance use (physiological dependency) responders accounted for 21.23%, financial dependency responders for 43.45%, and psychological dependency responders for 15.96%. Significant gender and socio-economic class patterns of dependency were revealed. This substantial swathe of the Jamaican population acknowledged their own dependency and behavioural withdrawal response to physical or emotional loss in their life, and reported having dependency problems in managing their financial and monetary affairs. Three-quarters of the Jamaican responders of this survey ostensibly are free of the phenomenology of dependency while a more vulnerable one-quarter has insight that they are still locked in a struggle for psychological independence. The political and economic relations between psychological dependency and socio-political dependency are discussed.

    In order to examine the experience of parental divorce for adult women, a phenomenological method was used. Ten women were interviewed and the interviews were transcribed verbatim and thematized. The themes that came from the texts of the interviews transcripts and the researchers' reflections on the phenomenological research group analysis were: Before the Divorce, During the Divorce, and After the Divorce. These themes were centered on a contextual ground of Time Frame of the Divorce. The results of this study can provide individuals with a context for understanding their own experiences of parental divorce. These results could also be helpful for mental health clinicians in anticipating the themes that clients will discuss relative to the stages of their parents' divorce.

    To understand older adults' experiences of moving into extra care housing which offers enrichment activities alongside social and healthcare support. A longitudinal study was conducted which adopted a phenomenological approach to data generation and analysis. Semi-structured interviews were conducted in the first 18 months of living in extra care housing. Interpretative phenomenological analysis was used because its commitment to idiography enabled an in-depth analysis of the subjective lived experience of moving into extra care housing. Themes generated inductively were examined against an existential-phenomenological theory of well-being. Learning to live in an extra care community showed negotiating new relationships was not straightforward; maintaining friendships outside the community became more difficult as capacity declined. In springboard for opportunity/confinement, living in extra care provided new opportunities for social engagement and a restored sense of self. Over time horizons began to shrink as incapacities grew. Seeking care illustrated reticence to seek care, due to embarrassment and a sense of duty to one's partner. Becoming aged presented an ontological challenge. Nevertheless, some showed a readiness for death, a sense of homecoming. An authentic later life was possible but residents required emotional and social support to live through the transition and challenges of becoming aged. Enhancement activities boosted residents' quality of life but the range of activities could be extended to cater better for quieter, smaller scale events within the community; volunteer activity facilitators could be used here. Peer mentoring may help build new relationships and opportunities for interactive stimulation. Acknowledging the importance of feeling-empathic imagination-in caregiving may help staff and residents relate better to each other, thus helping individuals to become ontologically secure and live well to the end.

  2. "Phenomenology" and qualitative research methods.

    PubMed

    Nakayama, Y

    1994-01-01

    Phenomenology is generally based on phenomenological tradition from Husserl to Heidegger and Merleau-Ponty. As philosophical stances provide the assumptions in research methods, different philosophical stances produce different methods. However, the term "phenomenology" is used in various ways without the definition being given, such as phenomenological approach, phenomenological method, phenomenological research, etc. The term "phenomenology" is sometimes used as a paradigm and it is sometimes even viewed as synonymous with qualitative methods. As a result, the term "phenomenology" leads to conceptual confusions in qualitative research methods. The purpose of this paper is to examine the term "phenomenology" and explore philosophical assumptions, and discuss the relationship between philosophical stance and phenomenology as a qualitative research method in nursing.

    2012-10-01

    The problem of existence of long-range order in the isotropic quantum Heisenberg model on the D=1 lattice is reconsidered in view of the possibility of sufficiently slow decaying exchange interaction with infinite effective radius. It is shown that the macrosopic arguments given by Landau and Lifshitz and then supported microscopically by Mermin and Wagner fail for this case so that the non-zero spontaneous magnetization may yet exist. This result was anticipated by Thouless on the grounds of phenomenological analysis, and we give its microscopic foundation, which amounts to the generalization of Mermin-Wagner theorem for the case of the infinite second moment of the exchange interaction. Two well known in lattice statistics models - i.e., Kac-I and Kac-II - illustrate our results.

    An exploratory, qualitative, phenomenological study focused on the experience of pain while participating in sexual masochistic acts. Semi-structured interviews were conducted with nine individuals (four female, five male) who regularly participate in sexually masochistic acts and point to pain as central to their experience. Qualitative analysis of the data revealed several key characteristics of the participant's experience: the first time, intoxication, craving and withdrawal, tolerance, pain as control, and the pain inducing partner. The findings indicate that the way pain is experienced while mitigated through masochistic behavior creates an addictive process that coincides with a chronic behavioral spin contextualization. This article presents a preliminary model of addiction to physical pain in light of the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) definition of substance-related and addictive disorders and the behavioral spin theory.

    Interactions between dark matter and dark energy which result in a power-law behavior (with respect to the cosmic scale factor) of the ratio between the energy densities of the dark components (thus generalizing the ΛCDM model) have been considered as an attempt to alleviate the cosmic coincidence problem phenomenologically. We generalize this approach by allowing for a variable equation of state for the dark energy within the CPL-parametrization. Based on analytic solutions for the Hubble rate and using the Constitution and Union2 SNIa sets, we present a statistical analysis and classify different interacting and non-interacting models according to the Akaikemore » (AIC) and the Bayesian (BIC) information criteria. We do not find noticeable evidence for an alleviation of the coincidence problem with the mentioned type of interaction.« less

  6. Measuring technical and mathematical investigation of multiple reignitions at the switching of a motor using vacuum circuit breakers

    NASA Astrophysics Data System (ADS)

    Luxa, Andreas

    The necessary conditions in switching system and vacuum circuit breaker for the occurrence of multiple re-ignitions and accompanying effects were examined. The shape of the occurring voltages was determined in relationship to other types of overvoltage. A phenomenological model of the arc, based on an extension of the Mayr equation for arcs was used with the simulation program NETOMAC for the switching transients. Factors which affect the arc parameters were analyzed. The results were statistically verified by 3000 three-phase switching tests on 3 standard vacuum circuit breakers under realistic systems conditions; the occurring overvoltage level was measured. Dimensioning criteria for motor simulation circuits in power plants were formulated on the basis of a theoretical equivalence analysis and experimental studies. The simulation model allows a sufficiently correct estimation of all effects.

    2015-03-01

    We review some recent developments in the statistical mechanics of isolated quantum systems. We provide a brief introduction to quantum thermalization, paying particular attention to the eigenstate thermalization hypothesis (ETH) and the resulting single-eigenstate statistical mechanics. We then focus on a class of systems that fail to quantum thermalize and whose eigenstates violate the ETH: These are the many-body Anderson-localized systems; their long-time properties are not captured by the conventional ensembles of quantum statistical mechanics. These systems can forever locally remember information about their local initial conditions and are thus of interest for possibilities of storing quantum information. We discuss key features of many-body localization (MBL) and review a phenomenology of the MBL phase. Single-eigenstate statistical mechanics within the MBL phase reveal dynamically stable ordered phases, and phase transitions among them, that are invisible to equilibrium statistical mechanics and can occur at high energy and low spatial dimensionality, where equilibrium ordering is forbidden.

    Little is known about the experiences of fathers of children with congenital heart disease. Using interpretative phenomenological analysis, the lived experiences of six fathers were explored. Two master themes emerged: 'relinquishing and reclaiming control' and 'living in the shadow of illness'. Subordinate themes included playing the support act, a pragmatic/emotional dichotomy, and becoming the child's protector. Other themes included living in limbo and redefining 'normality' to encompass the condition. Theoretical links are made between these findings and existing literature while clinical implications include the need to involve fathers in decision-making and to respect their need to maintain control.

    This study explored six women's experiences of primary dysmenorrhoea using semi-structured interviews analysed using interpretative phenomenological analysis. Rather than focusing on pain, participants broadened the study focus to coping with the menstrual process as a whole. This was seen to be mediated by menstrual taboos and by the theme of 'order', arising from a strong feeling of a menstrual timetable and the need for rational explanation. Another theme was pain as a separate entity, which was connected to the theme of order. Placing dysmenorrhoea in its context may be useful for health-care professionals treating women with the condition. © The Author(s) 2013.

    This paper aims to analyze Michel Foucault's position toward phenomenological psychology and psychopathology during the 1950s, in light of the new documentary sources available today. Our investigation is especially focused on one of the courses given by Foucault at the University of Lille between 1952 and 1954, namely, the course on "Binswanger and phenomenology" (1953-54). The analysis of this course, which was conceived by Foucault within the context of a philosophical reflection on the anthropological problem of psychopathology, will finally allow us to re-ascribe Foucault the place he deserves in the field of "philosophy of psychiatry".

The findings are conceptualized into three areas: first, the encounter 'at the crossroads between remission and relapse'; second, the way that 'anorexia reveals itself'; and finally, the way the 'ménage à trois' works, including the illness fully as part of the couple. Psychotherapists should take into account the context of the couple and the complex interaction between the couple and the illness to support both partners' development of appropriate responses.

  15. On the statistics of increments in strong Alfvenic turbulence

    In-situ measurements have shown that the solar wind is dominated by non-compressive Alfvén-like fluctuations of plasma velocity and magnetic field over a broad range of scales. In this work, we present recent progress in understanding intermittency in Alfvenic turbulence by investigating the statistics of Elsasser increments from simulations of steadily driven Reduced MHD with numerical resolutions up to 2048^3. The nature of these statistics guards a close relation to the fundamental properties of small-scale structures in which the turbulence is ultimately dissipated and therefore has profound implications in the possible contribution of turbulence to the heating of the solar wind. We extensively investigate the properties and three-dimensional structure of probability density functions (PDFs) of increments and compare with recent phenomenological models of intermittency in MHD turbulence.

  16. Revision of the Phenomenological Characteristics of the Algol-Type Stars Using the Nav Algorithm

    NASA Astrophysics Data System (ADS)

    Tkachenko, M. G.; Andronov, I. L.; Chinarova, L. L.

    Phenomenological characteristics of the sample of the Algol-type stars are revised using a recently developed NAV ("New Algol Variable") algorithm (2012Ap.....55..536A, 2012arXiv 1212.6707A) and compared to that obtained using common methods of Trigonometric Polynomial Fit (TP) or local Algebraic Polynomial (A) fit of a fixed or (alternately) statistically optimal degree (1994OAP.....7...49A, 2003ASPC..292..391A). The computer program NAV is introduced, which allows to determine the best fit with 7 "linear" and 5 "nonlinear" parameters and their error estimates. The number of parameters is much smaller than for the TP fit (typically 20-40, depending on the width of the eclipse, and is much smaller (5-20) for the W UMa and β Lyrae-type stars. This causes more smooth approximation taking into account the reflection and ellipsoidal effects (TP2) and generally different shapes of the primary and secondary eclipses. An application of the method to two-color CCD photometry to the recently discovered eclipsing variable 2MASS J18024395 + 4003309 = VSX J180243.9 +400331 (2015JASS...32..101A) allowed to make estimates of the physical parameters of the binary system based on the phenomenological parameters of the light curve. The phenomenological parameters of the light curves were determined for the sample of newly discovered EA and EW-type stars (VSX J223429.3+552903, VSX J223421.4+553013, VSX J223416.2+553424, USNO-B1.0 1347-0483658, UCAC3-191-085589, VSX J180755.6+074711= UCAC3 196-166827). Despite we have used original observations published by the discoverers, the accuracy estimates of the period using the NAV method are typically better than the original ones.

  17. Living With Chronic Lower Pulmonary Disease: Disruptions of the Embodied Phenomenological Self.

    PubMed

    Pooler, Charlotte

    2014-01-01

    In this article, I present a phenomenological study of individuals' experiences of living with moderate to very severe chronic lower pulmonary disease (chronic obstructive pulmonary disease, asthma, or both). Phenomenology is a philosophy, distinct from descriptive or thematic research, which is useful as a foundation for scientific inquiry. In this study, I used the lens of Merleau-Ponty to understand and interpret participants' experiences of living with pulmonary disease, and the approach of van Manen for analysis. I conclude that in chronic pulmonary disease, awareness of breathing and the body is experienced in the sounds, sensations, and signals of breathing and the body, and in the experiences of the body-in-the-world. Central themes of being-in-the-world from the study describe the disruption of the embodied phenomenological self: Participants experienced slowing down, doing less, and having to stop due to shortness of breath. Both chronic and acute dyspnea were prevalent and the taken-for-granted aspects of daily activities were disrupted. Findings of this study have implications for public and patient education, and opportunities for integration of experiential aspects within nursing education and practice.

    This paper traces the development of phenomenology as a philosophy originating from the writings of Husserl to its use in phenomenological research and theory development in nursing. The key issues of phenomenological reduction and bracketing are also discussed as they play a pivotal role in the how phenomenological research studies are approached. What has become to be known as "new" phenomenology is also explored and the key differences between it and "traditional" phenomenology are discussed. van Manen's phenomenology is also considered in light of its contemporary popularity among nurse researchers.

    There are several basic structures upon which anorexia nervosa could develop: hostility between mother and daughter, feministic protest, abandonnism, the ascetic structure, the reluctance against the being-thrown-on-the-world, asw. The phenomenological analysis reveals, through these different structures, a common distress. The patient feels the others, and also, the existence, as a violence. Yet, she feels help ass in her fight against this violence. So she takes her own body as hostage in order to delay her entry in the existence.

Patients with nonrheumatic paroxysmal AF (n=105) and 100 patients with panic attacks (n=100). Clinical, cardiological and neurological examination, analysis of patients complaints during attacks of AF, and comparison them with diagnostic criteria for panic attack. It was found that clinical picture of attacks of AF comprised vegetative, emotional and functional neurological phenomena similar to those characteristic for panic attacks. This similarity as well as positive therapeutic effect of clonazepam allowed to propose a novel pathogenic mechanism of AF attacks. Severity of psychovegetative disorders during paroxysm of AF could be evaluated by calculation of psychovegetative iudex: Psychovegetative index should be used for detection of panic attack-like component in clinical picture of AF paroxysm and thus for determination of indications for inclusion of vegetotropic drugs, e. g. clonazepam, in complex preventive therapy.

    Leisure is an important quality of life factor for older Korean immigrants. The purpose of this study was to explore leisure benefits associated with health among older Korean immigrants. A total of 18 individuals participated in the study. Using interpretative phenomenological analysis (IPA), three themes emerged from participants' personal statements and experiences: (a) experiencing psychological benefits, (b) strengthening social connections, and (c) coping with acculturative stress. The findings indicate that leisure provided a context in which older Korean immigrants created an emotional and social support system that helped them to experience psychological and social benefits. This research suggested that older Korean immigrants used leisure as a coping mechanism that results in health and well-being.

    This study aims to explore the individual experience of living with cancer pain. This qualitative study was performed by using a phenomenological research design. In-depth and open interviews with participants were conducted to collect the data and a qualitative Colaizzi method of analysis was performed. Following the analysis of the data, the expressions made by the cancer patients during the interviews were grouped under 5 themes. Consistent with the questionnaire format, 5 themes and 19 subthemes of responses were determined describing the pain of the cancer patients. The results of our study have demonstrated that cancer patients go through negative physical, psychological, and social experiences due to the pain they suffered.

    The occupations of mothering have gained attention in occupation-based research and literature; however, many aspects of mothering remain unexplored. PURPOSE; The purpose of this study was to gain insight into mothers' perceptions of their occupations when mothering a child with feeding difficulties. Study design used mixed methodology utilizing the Parental Stress Scale (PSS), Life Satisfaction Index for Parents (LSI-P), and phenomenological interviews. Comparison of the datasets illuminated the quantitative findings with the words of the women interviewed. Although there was only one statistically significant finding in the quantitative data in terms of satisfaction with leisure and recreation, the qualitative data provided rich descriptions of mothers' perceptions of stress and life satisfaction. Mixed methods data analysis revealed the complex nature of the interaction between mothering occupations and mothering a child with feeding concerns as well as how these concerns might influence occupational therapy practice.

  5. Skyscape Archaeology: an emerging interdiscipline for archaeoastronomers and archaeologists

    Henty, Liz

    2016-02-01

    For historical reasons archaeoastronomy and archaeology differ in their approach to prehistoric monuments and this has created a divide between the disciplines which adopt seemingly incompatible methodologies. The reasons behind the impasse will be explored to show how these different approaches gave rise to their respective methods. Archaeology investigations tend to concentrate on single site analysis whereas archaeoastronomical surveys tend to be data driven from the examination of a large number of similar sets. A comparison will be made between traditional archaeoastronomical data gathering and an emerging methodology which looks at sites on a small scale and combines archaeology and astronomy. Silva's recent research in Portugal and this author's survey in Scotland have explored this methodology and termed it skyscape archaeology. This paper argues that this type of phenomenological skyscape archaeology offers an alternative to large scale statistical studies which analyse astronomical data obtained from a large number of superficially similar archaeological sites.

    22q11.2 deletion syndrome (22q11.2DS) is the most common microdeletion syndrome. However, there is little research examining the effect of this multisystem disorder on the family, particularly siblings. The current study was a phenomenological exploration of sense-making in siblings of a person with 22q11.2DS. Interpretative phenomenological analysis informed a detailed and open examination of being a sibling of a person with 22q11.2DS. Using in-depth semistructured interviews, five typically developing siblings (two men, three women) of people with 22q11.2DS were individually interviewed, providing the data set for transcription and thematic analysis. The theme 'They are the priority' overarched two subordinate themes that emerged from participants' descriptions of the struggle with acceptance and finding positive meaning. Participants oscillated between conflicting feelings about their sibling with 22q11.2DS always taking centre stage. For example, they felt anger, guilt and resentment; yet, they also embraced patience, empathy and gratitude. This phenomenological study provides a foundation for future research relating to 22q11.2DS and fostering family wellbeing, particularly around acceptance and psychological growth. The siblings in this study actively withdrew from their family to allow prioritisation of their affected sibling. However, this does not mean that their needs should be overlooked. There are easily accessible resources to support siblings of individuals with disabilities, and it is important for health professionals and parents to consider these options. © 2017 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

    Phenomenology was born with the mission to give foundations for science of experience and to open consciousness to scientific study. The influence of phenomenology initiated in the works of Husserl and continued in a wide range of works of others was immense, but mainly within the confines of philosophy and the humanities. The actual attempts to develop a scientific discipline of the study of consciousness and to carry out research on cognition and consciousness were always based on the methods of traditional science in which elimination of the subjective has been always a primary tenet. Thus, focus was mainly on neurological correlates of conscious phenomena. The present paper is an attempt to initiate an extension and revision of phenomenological methodology with the use of philosophical and scientific experience and knowledge accumulated in a century of inquiry and research in relevant disciplines. The question which disciplines are relevant is crucial and our answer is innovative. The range of disciplines involved here is from information science and studies of computation, up to cultural psychology and the studies of philosophical traditions of the East. Concepts related to information and computation studies provide a general conceptual framework free from the limitations of particular languages and of linguistic analysis. This conceptual framework is extending the original perspective of phenomenology to issues of modern technology and science. Cultural psychology gives us tools to root out what in phenomenology was considered universal for humanity, but was a result of European ethnocentrism. Most important here is the contrast between individualistic and collectivistic cultural determinants of consciousness. Finally, philosophical tradition of the East gives alternatives in seeking solutions for fundamental problems. This general outline of the research methodology is illustrated by an example of its use when phenomenology is studied within the conceptual framework of information. Copyright © 2015.

  9. Collaboration between science teacher educators and science faculty from arts and sciences for the purpose of developing a middle childhood science teacher education program: A case study

    1998-12-01

    The science teacher educators at a midwestern university set a goal to establish a collaborative relationship between themselves and representatives from the College of Arts & Sciences for the purpose of developing a middle childhood science education program. The coming together of these two faculties provided a unique opportunity to explore the issues and experiences that emerge as such a collaborative relationship is formed. In order to gain a holistic perspective of the collaboration, a phenomenological case study design and methods were utilized. The study took a qualitative approach to allow the experiences and issues to emerge in a naturalistic manner. The question, 'What are the issues and experiences that emerge as science teacher educators and science faculty attempt to form a collaborative relationship for the purpose of developing a middle childhood science teacher program?' was answered by gathering a wealth of data. These data were collected by means of semi-structured interviews, observations and written document reviews. An overall picture was painted of the case by means of heuristic, phenomenological, and issues analyses. The researcher followed Moustakas' Phases of Heuristic Research to answer the questions 'What does science mean to me?' and 'What are my beliefs about the issues guiding this case?' prior to completing the phenomenological analysis. The phenomenological analysis followed Moustakas' 'Modification of the Van Kaam Methods of Analysis of Phenomenological Data'. This inquiry showed that the participants in this study came to the collaboration for many different reasons and ideas about the purpose for such a relationship. The participants also had very different ideas about how such a relationship should be conducted. These differences combined to create some issues that affected the development of curriculum and instruction. The issues involved the lack of (a) mutual respect for the work of the partners, (b) understanding about the roles and responsibilities of the partners, (c) a clear and understandable goal, and (d) time to collaborate. If not addressed, these are the issues that may prohibit the establishment of a successful collaboration, thus affecting the development of a top quality middle childhood science teacher education program.

  10. The effect of surface polaritons on mode damping in an irregular hollow dielectric waveguide operating in the middle infrared

    Consideration is given to the effect of surface polaritons induced by the rough walls of a hallow channel on the mode propagation constants of a dielectric waveguide. The mode propagation characteristics of the waveguide were analyzed within the framework of conventional geometric optics theory, and the results are compared with phenomenological data concerning the wave reflection from a statistically uneven surface. The dielectric permittivity function of the uneven surface had a small imaginary component and a negative real component. It is shown that statistical irregularities associated with the walls of the guiding channel can lead to enhanced damping in the waveguide modes.

    We consider the phenomenological implications of the violation of the Pauli exclusion principle for neutrinos, focusing on cosmological observables such as the spectrum of Cosmic Microwave Background anisotropies, Baryon Acoustic Oscillations and the primordial abundances of light elements. Neutrinos that behave (at least partly) as bosonic particles have a modified equilibrium distribution function that implies a different influence on the evolution of the Universe that, in the case of massive neutrinos, can not be simply parametrized by a change in the effective number of neutrinos. Our results show that, despite the precision of the available cosmological data, only very weak bounds can be obtained on neutrino statistics, disfavouring a more bosonic behaviour at less than 2σ.

  12. Psychotherapy and despair in the prison setting.

    2015-01-01

    The purpose of this paper is to outline research which aimed to explore psychotherapists' experience of working with despair, in the UK prison setting, through a qualitative phenomenological approach. Within the forensic psychological literature, despair is considered a pathology, associated with suicide and self-harm, resulting from the prisoners histories and the coercive prison setting. In turn, therapeutic writings outline the importance of therapy in the prison setting with despair in providing coping skills, containment and learning opportunities for the prisoners involved. Within the study, ten psychotherapists were interviewed as to their experience of working with clients in despair in the prison setting. The data were analysed via the phenomenological research method Empirical Phenomenological Analysis (EPA), and a secondary analysis through reverie. Through the analysis by EPA, despair emerged in the prison setting as a destabilising phenomenon to which there was no protocol for working with it. Participants also described the prisoners' despair and the despairing prison setting, touching on their own sense of vulnerability and despair. However, drawing on the secondary analysis by reverie, the researcher also became aware of how the phenomenon of despair emerged not simply through the said, but also through the intersubjective. It was therefore through the secondary analysis by reverie that the importance of the attendance to aspects of intersubjectivity in prison research emerged. This paper contributes to the therapeutic writings on despair in the prison setting, alongside holding implications for qualitative research in the prison setting.

  13. Newton vs. Munchhausen in upper-troposphere dynamics

    NASA Astrophysics Data System (ADS)

    Bergmann, Juan Carlos

    2010-05-01

    Atmospheric angular momentum (AM) balance depends crucially on the existence and magnitude of the planetary-scale AM transport by 'eddies' in the upper troposphere. Its divergence has to provide the torque, which is necessary to realise the upper-troposphere branch of meridional circulation. (In the boundary layer, the torque is provided by surface-friction.) The torques in neighbouring circulation cells are opposed, so that the AM transport mediates a torque-interaction between the circulation cells. This interaction corresponds to a clear requirement of Newton's Third Law: torques (forces) exist only in interaction with other bodies, and their sum is equal to zero. In Münchhausen's physics, force (and torque) exists without interaction: In a famous tale, Münchhausen saves himself (and his horse!) from drowning in a swamp-hole by pulling himself up at his hair. Münchhausen-physics situations arise in the dynamical analysis of the torque exerted by a single eddy and in analysis of the cause for the AM transport of the single eddy. The local AM transport of the single eddy is defined by the difference in zonal velocity between the pole-ward and equator-ward branches (Δu) multiplied with meridional velocity-magnitude (¦v¦). For the average over many eddies, it transforms to the average product of the deviations of zonal and meridional velocities from their local averages (, eddy-correlation; the complete formulations include the local radius of rotation but it is omitted here for simplicity reasons). This definition is phenomenological but not dynamical. In dynamical analysis it turns out that the torque-related zonal equation of motion of an AM-transporting single eddy can be formulated without torque-interaction with other bodies (torque-free eddy). Newton III implies also the phenomenological torque (transport divergence -δ(¦v¦Δu)/δy) to be zero for this case because there is no partner of torque-interaction. However, the dynamically torque-free single eddy has an unavoidable 'transport' divergence - especially in the turning-region of the meridional motion. Thus, there is a phenomenological 'torque' (non-zero 'transport' divergence) without torque-interaction - a classical Münchhausen situation! The dynamical cause of phenomenological 'AM transport' and associated phenomenological 'torques' of the dynamically torque-free single eddy is 'hidden' in the non-torque-related meridional equation of motion for steady-state: δv-δ t = - u δv-δx - vδv-δ y - f u(x) + Fy(x) = 0 . Strong variation of the meridional pressure-gradient force Fy(x) (no torque!) over the eddy-path (longitude x) produces varying zonal velocities u(x) that are falsely interpreted as 'AM transport' on the phenomenological level (the 'advective' terms are negligible outside the eddy's turning regions). Thus, creation and destruction of phenomenological 'AM transport' (Δu) in a single eddy do not originate from torque-interaction with other bodies - another classical Münchhausen situation! Should the previous analysis be ignored in favour of maintaining the 'established' ideas of upper-troposphere dynamics or should there be an effort to formulate new ideas that are in accordance with Newtonian physics?

  14. A Mother’s Heart is Weighed Down with Stones: A Phenomenological Approach to the Experience of Transnational Motherhood

    PubMed Central

    2015-01-01

    Although recent scholarship on transnational mothers has rigorously examined the effect of migration on gender constructs and ideologies, it neglects analysis of the lived experience of separated mothers and children. In privileging the exploration of transnational separations through the single analytical lens of gender, such research reduces the embodied distress of mothers and children to mere “gender false consciousness.” This paper calls upon anthropologists to redress this oversight by undertaking a phenomenological analysis of the lived experience of transnational motherhood. Eschewing an analysis of mothers and children as isolated social roles, I show that the suffering of mothers and children is profoundly relational. Through analysis of the narratives of undocumented Salvadoran mothers residing in the U.S., I show how the strain of such mothers’ undocumented status is lived and shouldered within the intersubjective space of the family.

    2016-01-01

    Objectives Identifying depression in older adults with cancer presents a set of unique challenges, as it combines the confounding influences of cancer and its treatment with the developmental changes associated with aging. This paper reviews the phenomenology of depression in older adults, and individuals diagnosed with cancer. Method PsychInfo, PubMed, Web of Science, and Google Scholar databases were searched for English-language studies addressing the phenomenology, symptoms, or assessment of depression in older adults and those with cancer. Results The Diagnostic and Statistical Manual for Mental Disorders (DSM) criteria that appear to be relevant to both older adults and cancer patients are anhedonia, concentration difficulties, sleep disturbances, psychomotor retardation/agitation, and loss of energy. Possible alternative criteria that may be important considerations included constructs such as loss of purpose, loneliness, and irritability in older adults. Among cancer patients, tearfulness, social withdrawal, and not participating in treatment despite ability to do so were identified as potentially important symptoms. Conclusions Current DSM criteria may not adequately assess depression in older cancer patients and alternative criteria may be important to inform the understanding and identification of depression in this population. Enhancing diagnostic accuracy of depression is important as both the over-diagnosis and under-diagnosis is accompanied with significant costs. Thus, continued research exploring the phenomenology and identifying effective indicators of depression in older cancer patients is needed. PMID:26312455

  16. Max Planck and the birth of the quantum hypothesis

    NASA Astrophysics Data System (ADS)

    Nauenberg, Michael

    2016-09-01

    Based on the functional dependence of entropy on energy, and on Wien's distribution for black-body radiation, Max Planck obtained a formula for this radiation by an interpolation relation that fitted the experimental measurements of thermal radiation at the Physikalisch Technishe Reichanstalt (PTR) in Berlin in the late 19th century. Surprisingly, his purely phenomenological result turned out to be not just an approximation, as would have been expected, but an exact relation. To obtain a physical interpretation for his formula, Planck then turned to Boltzmann's 1877 paper on the statistical interpretation of entropy, which led him to introduce the fundamental concept of energy discreteness into physics. A novel aspect of our account that has been missed in previous historical studies of Planck's discovery is to show that Planck could have found his phenomenological formula partially derived in Boltzmann's paper in terms of a variational parameter. But the dependence of this parameter on temperature is not contained in this paper, and it was first derived by Planck.

  18. From organized high throughput data to phenomenological theory: The example of dielectric breakdown

    Understanding the behavior (and failure) of dielectric insulators experiencing extreme electric fields is critical to the operation of present and emerging electrical and electronic devices. Despite its importance, the development of a predictive theory of dielectric breakdown has remained a challenge, owing to the complex multiscale nature of this process. Here, we focus on the intrinsic dielectric breakdown field of insulators--the theoretical limit of breakdown determined purely by the chemistry of the material, i.e., the elements the material is composed of, the atomic-level structure, and the bonding. Starting from a benchmark dataset (generated from laborious first principles computations) of the intrinsic dielectric breakdown field of a variety of model insulators, simple predictive phenomenological models of dielectric breakdown are distilled using advanced statistical or machine learning schemes, revealing key correlations and analytical relationships between the breakdown field and easily accessible material properties. The models are shown to be general, and can hence guide the screening and systematic identification of high electric field tolerant materials.

  19. Langevin equation in systems with also negative temperatures

    2018-04-01

    We discuss how to derive a Langevin equation (LE) in non standard systems, i.e. when the kinetic part of the Hamiltonian is not the usual quadratic function. This generalization allows to consider also cases with negative absolute temperature. We first give some phenomenological arguments suggesting the shape of the viscous drift, replacing the usual linear viscous damping, and its relation with the diffusion coefficient modulating the white noise term. As a second step, we implement a procedure to reconstruct the drift and the diffusion term of the LE from the time-series of the momentum of a heavy particle embedded in a large Hamiltonian system. The results of our reconstruction are in good agreement with the phenomenological arguments. Applying the method to systems with negative temperature, we can observe that also in this case there is a suitable LE, obtained with a precise protocol, able to reproduce in a proper way the statistical features of the slow variables. In other words, even in this context, systems with negative temperature do not show any pathology.

  20. Neutrino Oscillations at Proton Accelerators

    2002-12-01

    Data from many different experiments have started to build a first glimpse of the phenomenology associated with neutrino oscillations. Results on atmospheric and solar neutrinos are particularly clear while a third result from LSND suggests a possibly very complex oscillation phenomenology. As impressive as the results from current experiments are, it is clear that we are just getting started on a long-term experimental program to understand neutrino masses, mixings and the physics which produce them. A number of exciting fundamental physics possibilities exist, including that neutrino oscillations could demonstrate CP or CPT violation and could be tied to exotic high-energy phenomena including strings and extra dimensions. A complete exploration of oscillation phenomena demands many experiments, including those possible using neutrino beams produced at high energy proton accelerators. Most existing neutrino experiments are statistics limited even though they use gigantic detectors. High intensity proton beams are essential for producing the intense neutrino beams which we need for next generation neutrino oscillation experiments.

  1. Gyrofluid modeling and phenomenology of low-βe Alfvén wave turbulence

    2018-04-01

    A two-field reduced gyrofluid model including electron inertia, ion finite Larmor radius corrections, and parallel magnetic field fluctuations is derived from the model of Brizard [Brizard, Phys. Fluids B 4, 1213 (1992)]. It assumes low βe, where βe indicates the ratio between the equilibrium electron pressure and the magnetic pressure exerted by a strong uniform magnetic guide field, but permits an arbitrary ion-to-electron equilibrium temperature ratio. It is shown to have a noncanonical Hamiltonian structure and provides a convenient framework for studying kinetic Alfvén wave turbulence, from magnetohydrodynamics to sub-de scales (where de holds for the electron skin depth). Magnetic energy spectra are phenomenologically determined within energy and generalized cross-helicity cascades in the perpendicular spectral plane. Arguments based on absolute statistical equilibria are used to predict the direction of the transfers, pointing out that, within the sub-ion range, the generalized cross-helicity could display an inverse cascade if injected at small scales, for example by reconnection processes.

  2. Model-based image analysis of a tethered Brownian fibre for shear stress sensing

    PubMed Central

    2017-01-01

    The measurement of fluid dynamic shear stress acting on a biologically relevant surface is a challenging problem, particularly in the complex environment of, for example, the vasculature. While an experimental method for the direct detection of wall shear stress via the imaging of a synthetic biology nanorod has recently been developed, the data interpretation so far has been limited to phenomenological random walk modelling, small-angle approximation, and image analysis techniques which do not take into account the production of an image from a three-dimensional subject. In this report, we develop a mathematical and statistical framework to estimate shear stress from rapid imaging sequences based firstly on stochastic modelling of the dynamics of a tethered Brownian fibre in shear flow, and secondly on a novel model-based image analysis, which reconstructs fibre positions by solving the inverse problem of image formation. This framework is tested on experimental data, providing the first mechanistically rational analysis of the novel assay. What follows further develops the established theory for an untethered particle in a semi-dilute suspension, which is of relevance to, for example, the study of Brownian nanowires without flow, and presents new ideas in the field of multi-disciplinary image analysis.

  3. Experience of Time Passage:. Phenomenology, Psychophysics, and Biophysical Modelling

    2005-10-01

    The experience of time's passing appears, from the 1st person perspective, to be a primordial subjective experience, seemingly inaccessible to the 3rd person accounts of time perception (psychophysics, cognitive psychology). In our analysis of the `dual klepsydra' model of reproduction of temporal durations, time passage occurs as a cognitive construct, based upon more elementary (`proto-cognitive') function of the psychophysical organism. This conclusion contradicts the common concepts of `subjective' or `psychological' time as readings of an `internal clock'. Our study shows how phenomenological, experimental and modelling approaches can be fruitfully combined.

    To assist the researcher in understanding the similarities and differences between the Husserlian and Heideggerian philosophies of phenomenology, and how that philosophy can inform nursing research as a useful methodology. Nurse researchers using phenomenology as a methodology need to understand the philosophy of phenomenology to produce a research design that is philosophically congruent. However, phenomenology has a long and complex history of development, and may be difficult to understand and apply. The author draws from Heidegger (1962), Gadamer (2004), and nurse scholars and methodologists. To give the reader a sense of the development of the philosophy of phenomenology, the author briefly recounts its historical origins and interpretations, specifically related to Husserl, Heidegger and Gadamer. The author outlines the ontological and epistemological assumptions of Husserlian and Heideggerian phenomenology and guidance for methodology inspired by these philosophers. Difficulties with engaging in phenomenological research are addressed, especially the processes of phenomenological reduction and bracketing, and the lack of clarity about the methods of interpretation. Despite its complexity, phenomenology can provide the nurse researcher with indepth insight into nursing practice. An understanding of phenomenology can guide nurse researchers to produce results that have meaning in nursing patient care.

  7. Relative relationships of general shame and body shame with body dysmorphic phenomenology and psychosocial outcomes.

    Body Dysmorphic Disorder (BDD) is characterized by a preoccupation with a perceived flaw in appearance and repetitive avoidance behaviors. BDD involves severe psychosocial outcomes (e.g., depression, suicidality, functional impairment). Identifying correlates of BDD symptoms and outcomes can inform treatment. Shame, a painful emotion felt in response to critical self-judgment, may be one key correlate. However, research on shame in BDD is scarce and previous studies have not distinguished general shame from body shame. This study examines the relative relationships between body shame and general shame with body dysmorphic phenomenology and psychosocial outcomes. Participants ( N = 184) were recruited online via BDD organizations and completed a survey. Path analysis was used to examine associations between body and general shame with 1) body dysmorphic phenomenology and 2) depression severity, suicide risk, and functional impairment. Both types of shame were differentially related to outcomes. Body shame was more strongly related to phenomenology, whereas general shame was more strongly related to psychosocial outcomes. Thus, it may be important for BDD treatment to focus on reducing both general and body shame. Further research should evaluate whether current treatments adequately address and reduce general and body shame, and whether addressing shame promotes better treatment outcomes.

    We have investigated the correlation between magnetocaloric and electrical properties of La0.47Pr0.2Pb0.33MnO3 perovskite prepared using the sol-gel method. Rietveld analysis of X-ray diffraction (XRD) pattern shows pure crystalline phase with rhombohedral ? structure. Magnetic entropy change, relative cooling power (RCP) and specific heat were predicted from M(T, μ0H) data at different magnetic fields with the help of the phenomenological model. The magnetic entropy change reaches a maximum value ? of about 3.96 J kg-1 K-1 for μ0H = 5 T corresponding to RCP of 183 J kg-1. These values are relatively higher, making our sample a promising candidate for the magnetic refrigeration. Electrical-resistivity measurements were well fitted with the phenomenological percolation model, which is based on the phase segregation of ferromagnetic-metallic clusters and paramagnetic-semiconductor regions. The temperature and magnetic field dependences of resistivity data, ρ(T, μ0H), allowed us to determine the magnetic entropy change ?. Results show that the as-obtained magnetic entropy change values are similar to those determined from the phenomenological model.

    2006-03-01

    Pro-anorexia Internet sites aim to promote, support and discuss anorexia nervosa. Media coverage has raised concerns that sites may increase the level of eating disorders. This research examines the meaning of participation in a pro-anorexia Internet site and its relationship with disordered eating by using an interpretative phenomenological analysis of fifteen separate message 'threads' followed over a six-week period. Four themes were identified: (1) tips and techniques; (2) 'ana' v. anorexia nervosa; (3) social support; and (4) need for anorexia. Findings suggest participation was multi-purpose, providing a coping function in relation to weight loss, and the contribution of sites to increased levels of eating disorders is not inevitable.

    Leisure is an important quality of life factor for older Korean immigrants. The purpose of this study was to explore leisure benefits associated with health among older Korean immigrants. A total of 18 individuals participated in the study. Using interpretative phenomenological analysis (IPA), three themes emerged from participants’ personal statements and experiences: (a) experiencing psychological benefits, (b) strengthening social connections, and (c) coping with acculturative stress. The findings indicate that leisure provided a context in which older Korean immigrants created an emotional and social support system that helped them to experience psychological and social benefits. This research suggested that older Korean immigrants used leisure as a coping mechanism that results in health and well-being. PMID:27914195

    Hopkins, Alison

    The aim of this study was to explore the lived experience of people who have non-healing venous ulcers using hermeneutic phenomenology. Unstructured interviews were carried out with five people who also completed a diary. Interpretative phenomenological analysis was utilized to identify themes and patterns. The core themes identified through analysis were biographical disruption, ways of coping, social implications and therapeutic relationships. The emergent themes reveal the impact of chronicity in participants' experience of chronic leg ulcers, their various emotional and problem-focused coping strategies and the positive role the district nurse plays in their lives. This study places leg ulceration within the body of literature on chronicity, linking nursing theory with the insights offered from health psychology.

  12. ``A Minority View'' Gian-Carlo Rota's Phenomenological Realism

    NASA Astrophysics Data System (ADS)

    Palombi, Fabrizio

    In 1997 Rota's second anthology was published, entitled Indiscrete Thoughts. The theses put forward in the book were "minority" positions in a Unites States cultural context that, after long having attempted to replace philosophy with logical analysis and the analysis of language (Hersh, 1997, pp. IX-X), was preparing to interpret it also in neuroscientific terms. Rota intended to show that he did not fear uncomfortable positions and chose the phrase "a minority view" as a provocative title for the philosophy section of the book, inspired by phenomenology. We cannot understand the importance of Rota's intellectual figure, within the American cultural context of the end of the twentieth century, and the importance of his heritage if we interpret it in terms of architectonic of philosophy.

    2013-01-01

    This study explored the nurse faculty experience of participating in a problem-based learning (PBL) faculty development program. Utilizing PBL as a pedagogical method requires a paradigm shift in the way faculty think about teaching, learning, and the teacher-student relationship. An interpretive phenomenological analysis approach was used to explore the faculty experience in a PBL development program. Four themes emerged: change in perception of the teacher-student relationship, struggle in letting go, uncertainty, and valuing PBL as a developmental process. Epistemic doubt happens when action and intent toward the PBL teaching perspective do not match underlying beliefs. Findings from this study call for ongoing administrative support for education on PBL while faculty take time to uncover hidden epistemological beliefs.

    Six young adults (aged 19-21 years) with repeat self-harm for over 5 years were interviewed about their self-harm, why they continued and what factors might help them to stop. Interpretative phenomenological analysis identified six themes: keeping self-harm private and hidden; self-harm as self-punishment; self-harm provides relief and comfort; habituation and escalation of self-harm; emotional gains and practical costs of cutting, and not believing they will stop completely. Young adults presented self-harm as an ingrained and purposeful behaviour which they could not stop, despite the costs and risks in early adulthood. Support strategies focused on coping skills, not just eradicating self-harm, are required.

  15. Principle component analyses of questionnaires measuring individual differences in synaesthetic phenomenology.

    PubMed

    Anderson, Hazel P; Ward, Jamie

    2015-05-01

    Questionnaires have been developed for categorising grapheme-colour synaesthetes into two sub-types based on phenomenology: associators and projectors. The general approach has been to assume a priori the existence of two sub-types on a single dimension (with endpoints as projector and associator) rather than explore, in a data-driven fashion, other possible models. We collected responses from 175 grapheme-colour synaesthetes on two questionnaires, the Illustrated Synaesthetic Experience Questionnaire (Skelton, Ludwig, & Mohr, 2009) and Rouw and Scholte's (2007) Projector-Associator Questionnaire. After Principle Component Analysis both questionnaires were comprised of two factors which coincide with the projector/associator distinction. This suggests that projectors and associators are not opposites of each other, but separate dimensions of experience (e.g. some synaesthetes claim to be both, others claim to be neither). The revised questionnaires provide a useful tool for researchers and insights into the phenomenology of synaesthesia. Copyright © 2015 Elsevier Inc. All rights reserved.

    In this study we used a model of adult learning to explore undergraduate students' views on how to improve the teaching of research methods and biostatistics. This was a secondary analysis of survey data of 600 undergraduate students from three medical schools in Uganda. The analysis looked at student's responses to an open ended section of a questionnaire on their views on undergraduate teaching of research methods and biostatistics. Qualitative phenomenological data analysis was done with a bias towards principles of adult learning. Students appreciated the importance of learning research methods and biostatistics as a way of understanding research problems; appropriately interpreting statistical concepts during their training and post-qualification practice; and translating the knowledge acquired. Stressful teaching environment and inadequate educational resource materials were identified as impediments to effective learning. Suggestions for improved learning included: early and continuous exposure to the course; more active and practical approach to teaching; and a need for mentorship. The current methods of teaching research methods and biostatistics leave most of the students in the dissonance phase of learning resulting in none or poor student engagement that results in a failure to comprehend and/or appreciate the principles governing the use of different research methods.

    This was a qualitative study conducted using an interpretative phenomenological approach. This study investigated the experience of pregnancy and childbirth in women with spinal cord injury (SCI). Brain and Spinal Cord Injury Research Center, Tehran University of Medical Sciences, Tehran, Iran. The data were collected using telecommunication and face-to-face semi-structured interviews with eight women with SCI. The study employed the interpretative phenomenological approach suggested by Van Manen in 2016 and thematic analysis to provide a comprehensive understanding of the childbearing experience of women with SCI. MAXQDA 10 software was used to manage the collected data. Five main themes have emerged from data analysis: "revivification", "fear and concern of motherhood with SCI", "flawed health care system", "maternal experience under a supportive umbrella", and "strengthening spirituality and religious belief". Childbearing had a positive effect on the family relationship, continuity of marriage, and quality of life following SCI. There are potential benefits in establishing a center that provides consultation on childbearing and childcare for women with SCI. Moreover, training for the medical team, which includes nurses, midwives, and specialists is highly recommended. Further research is needed to expand our understanding of childbearing from the perspectives of healthcare providers.

    To offer a complete outlook in a readable easy way of van Manen's hermeneutic-phenomenological method to nurses interested in undertaking phenomenological research. Phenomenology, as research methodology, involves a certain degree of complexity. It is difficult to identify a single article or author which sets out the didactic guidelines that specifically guide research of this kind. In this context, the theoretical-practical view of Max van Manen's Phenomenology of Practice may be seen as a rigorous guide and directive on which researchers may find support to undertake phenomenological research. Discussion paper. This discussion paper is based on our own experiences and supported by literature and theory. Our central sources of data have been the books and writings of Max van Manen and his website "Phenomenologyonline". The principal methods of the hermeneutic-phenomenological method are addressed and explained providing an enriching overview of phenomenology of practice. A proposal is made for the way the suggestions made by van Manen might be organized for use with the methods involved in Phenomenology of Practice: Social sciences, philosophical and philological methods. Thereby, nurse researchers interested in conducting phenomenological research may find a global outlook and support to understand and conduct this type of inquiry which draws on the art. The approach in this article may help nurse scholars and researchers reach an overall, encompassing perspective of the main methods and activities involved in doing phenomenological research. Nurses interested in doing phenomenology of practice are expected to commit with reflection and writing. © 2018 John Wiley & Sons Ltd.

    Organisms shape their own environment, which in turn affects their survival. This feedback becomes especially important for communities containing a large number of species; however, few existing approaches allow studying this regime, except in simulations. Here, we use methods of statistical physics to analytically solve a classic ecological model of resource competition introduced by MacArthur in 1969. We show that the nonintuitive phenomenology of highly diverse ecosystems includes a phase where the environment constructed by the community becomes fully decoupled from the outside world.

    The possible existence of maximal or near-maximal lepton mixing constitutes an intriguing challenge for fundamental theories of flavor. We study the phenomenological consequences of maximal and near-maximal mixing of the electron neutrino with other (x=tau and/or muon) neutrinos. We describe the deviations from maximal mixing in terms of a parameter ɛ≡1-2 sin2 θex and quantify the present experimental status for \\|ɛ\\|<0.3. We show that both probabilities and observables depend on ɛ quadratically when effects are due to vacuum oscillations and they depend on ɛ linearly if matter effects dominate. The most important information on νe mixing comes from solar neutrino experiments. We find that the global analysis of solar neutrino data allows maximal mixing with confidence level better than 99% for 10-8 eV2<~Δm2<~2×10-7 eV2. In the mass ranges Δm2>~1.5×10-5 eV2 and 4×10-10 eV2<~Δm2<~2×10-7 eV2 the full interval \\|ɛ\\|<0.3 is allowed within ~4σ (99.995% CL) We suggest ways to measure ɛ in future experiments. The observable that is most sensitive to ɛ is the rate [NC]/[CC] in combination with the day-night asymmetry in the SNO detector. With theoretical and statistical uncertainties, the expected accuracy after 5 years is Δɛ~0.07. We also discuss the effects of maximal and near-maximal νe mixing in atmospheric neutrinos, supernova neutrinos, and neutrinoless double beta decay.

    2010-10-01

    In exploring phenomenological literature, it is evident that the term 'phenomenology' holds rather different meanings depending upon the context. Phenomenology has been described as both a philosophical movement and an approach to human science research. The phenomenology of Husserl, Heidegger, Gadamer, and Merleau-Ponty was philosophical in nature and not intended to provide rules or procedures for conducting research. The Canadian social scientist, van Manen, however, introduced specific guidelines for conducting human science research, which is rooted in hermeneutic phenomenology and this particular method has been employed in professional disciplines such as education, nursing, clinical psychology, and law. The purpose of this paper is to explore the difference between the phenomenological method as described by van Manen and that of other philosophers such as Husserl, Heidegger, Gadamer, and Merleau-Ponty. In so doing, the author aims to address the blurred boundaries of phenomenology as a research method and as a philosophical movement and highlight the influence of these blurred boundaries on nursing knowledge development.

    Ecological diffusion is a theory that can be used to understand and forecast spatio-temporal processes such as dispersal, invasion, and the spread of disease. Hierarchical Bayesian modelling provides a framework to make statistical inference and probabilistic forecasts, using mechanistic ecological models. To illustrate, we show how hierarchical Bayesian models of ecological diffusion can be implemented for large data sets that are distributed densely across space and time. The hierarchical Bayesian approach is used to understand and forecast the growth and geographic spread in the prevalence of chronic wasting disease in white-tailed deer (Odocoileus virginianus). We compare statistical inference and forecasts from our hierarchical Bayesian model to phenomenological regression-based methods that are commonly used to analyse spatial occurrence data. The mechanistic statistical model based on ecological diffusion led to important ecological insights, obviated a commonly ignored type of collinearity, and was the most accurate method for forecasting.

    Slaughterhouses constitute a unique work setting exposing employees to particular physical and psychological health challenges. Research that focuses on the well-being of slaughterhouse employees is limited, and the aim of this study was to explore their well-being by conducting a hermeneutic phenomenological study of specifically the slaughterfloor employees' work-life experiences. The study was conducted in a South African commercial abattoir setting. Thirteen slaughterfloor employees and two managers of the slaughterfloor section participated in unstructured interviews. A hermeneutic phenomenological approach to data analysis was adopted following the stages of a naïve reading, a structural thematic analysis, and a comprehensive understanding. Data analysis resulted in four process-related themes representing the different stages of becoming a slaughterer, (mal)adjusting to slaughter work, coping with and maintaining the work, and living with the psycho-social consequences of slaughter work. Results facilitate an understanding of how employee well-being manifests in each of these stages of being a slaughterfloor employee. The risk potential of employees suffering from post-traumatic stress syndrome was evident throughout the stages of being a slaughterfloor employee and offers a useful diagnostic framework to facilitate employee well-being assistance. Slaughterhouse management should develop a holistic focus addressing employee well-being needs evident in each of the stages of being a slaughter worker and by extending well-being interventions to the broader communities that the slaughterhouse functions in.

Members used the message board to seek (and provide) support to those with CRPS, and also to express their emotions, feelings and experiences linked to their condition. The message board provided an important source of support for a patient group that can otherwise become isolated as a result of their mobility problems. Furthermore, the analysis revealed the unrealistic hopes that patients can hold concerning the anticipated outcomes of their treatment. This is an important issue for healthcare professionals to explicitly address when interacting with the patient group.

  7. The cosmobiological balance of the emotional and spiritual worlds: phenomenological structuralism in traditional Chinese medical thought.

    PubMed

    Davis, S

    1996-03-01

    This paper points to a convergence of formal and rhetorical features in ancient Chinese cosmobiological theory, within which is developed a view of the inner life of human emotions. Inasmuch as there is an extensive classical tradition considering the emotions in conjunction with music, one can justify a structural analysis of medical texts treating disorder in emotional life, since emotions, musical interpretation and structural analysis all deal with systems interrelated in a transformational space largely independent of objective reference and propositional coordination. Following a section of ethnolinguistic sketches to provide grounds in some phenomenological worlds recognized by Chinese people, there is a textual analysis of a classical medical source for the treatment of emotional distress. Through close examination of the compositional schema of this text, it can be demonstrated that the standard categories of correlative cosmology are arrayed within a more comprehensive structural order.

  8. Phenomenology and adapted physical activity: philosophy and professional practice.

    Standal, Øyvind F

    2014-01-01

    Through the increased use of qualitative research methods, the term phenomenology has become a quite familiar notion for researchers in adapted physical activity (APA). In contrast to this increasing interest in phenomenology as methodology, relatively little work has focused on phenomenology as philosophy or as an approach to professional practice. Therefore, the purpose of this article is to examine the relevance of phenomenology as philosophy and as pedagogy to the field of APA. First, phenomenology as philosophy is introduced through three key notions, namely the first-person perspective, embodiment, and life-world. The relevance of these terms to APA is then outlined. Second, the concept of phenomenological pedagogy is introduced, and its application and potential for APA are discussed. In conclusion, it is argued that phenomenology can help theorize ways of understanding human difference in movement contexts and form a basis of action-oriented research aiming at developing professional practice.

    We report the first Interpretative Phenomenological Analysis examination of self-harm and experience of clinical services in young people in the public care system. Qualitative interviews with 24 looked-after young people were completed. Prevalent themes were 1) Changes in care placement, 2) Feelings of anger, 3) Not wanting/feeling able to talk, 4) Developing coping techniques, 5) Clinical services: A relational mixed bag (subthemes: feeling (i) patronized, not listened to, (ii) nothing being done, (iii) comfortable/able to talk). Placement change and anger were highly salient to self-harm in this group and experiences of clinical services depended on individual relationships with clinicians. Implications include increasing compassion in therapeutic relationships, recognizing and managing emotional dysregulation, and increasing support during placement changes.

  10. Outsourcing within aerospace manufacturing enterprises: A phenomenological study and outsourcing leadership model

    NASA Astrophysics Data System (ADS)

    Sampson, Enrique, Jr.

    Many aerospace workers believe transferring work projects abroad has an erosive effect on the U.S. aerospace industry (Pritchard, 2002). This qualitative phenomenological study examines factors for outsourcing decisions and the perceived effects of outsourcing on U.S. aerospace workers. The research sample consists of aerospace industry leaders and nonleaders from the East Coast, Midwest, and West Coast of the United States. Moustakas' modified van Kaam methods of analysis (1994) and Decision Explorer analysis software were applied to the interview transcripts. Resultant data identified five core themes: communication, best value, opportunities, cost, and offset consideration. The themes provided the framework for a model designed to assist leaders in making effective decisions and communicating the benefits of those decisions when considering outsourcing of work projects.

    This study analyzed eating disorder (ED) etiological factors for 100 midlife women ED inpatients, grouped by ED onset age: < 40 and > or = 40 years. Interpretative Phenomenological Analysis classified ED etiological influences into background contributors, immediate triggers, or sustainers. Family-of-origin issues, predominantly parental maltreatment, emerged as important background contributors, but not immediate ED triggers, regardless of onset age. Body image issues were also major background contributors regardless of onset age and further served as immediate ED triggers for many of the younger-onset patients, but not the older-onset patients. Family-of-choice and health issues were unimportant for younger-onset patients but were important ED contributors and triggers for older-onset patients. Emergent etiological differences suggest differential assessment and treatment needs for midlife ED patients based on ED onset age.

    To explore the occupational experiences of private security contractors working in a war zone and how it impacts on their mental health. Semistructured interviews were conducted with seven contractors employed by a large UK-based private security company. Interpretative phenomenological analysis was used to analyze the interview transcripts. Participants also completed the 12-item General Health Questionnaire and the Posttraumatic Stress Disorder Checklist. Four overarching themes emerged: the appeal of the job; vulnerability; keep going; and seeking help for stress in the workplace. No clinically significant levels of distress were reported. Contractors are frequently exposed to stressors known to increase risk of psychiatric difficulty in military personnel. A number of potential protective factors were identified. Only a minority of participants were open to seeking help for mental health difficulties.

    This study explores the attitude and feelings toward menopause among Azeri menopausal women using hermeneutic phenomenology based on Van Manen's approach. A total of 18 menopausal women who were attended in urban health centers of Tabriz, Iran, were recruited using a purposive sampling method. Data were gathered through semistructured interviews. Each interview was transcribed verbatim and analyzed simultaneously. Data analysis led to the emergence of five main themes: positive attitude, neutral attitude, negative attitude, positive feelings, and negative feelings. Participants had different feelings and attitude. Acceptance of menopause as a natural process helps women to have a neutral attitude toward menopause.

    In this work, we study all the observed a2 states and group them into the a2 meson family, where their total and two-body Okubo-Zweig-Iizuka allowed strong decay partial widths are calculated via the quark pair creation model. Taking into account the present experimental data, we further give the corresponding phenomenological analysis, which is valuable to test whether each a2 state can be assigned into the a2 meson family. What is more important is that the prediction of their decay behaviors will be helpful for future experimental study of the a2 states.

  15. Idols of the psychologist: Johannes Linschoten and the demise of phenomenological psychology in the Netherlands.

    PubMed

    van Hezewijk, René; Stam, Henderikus J

    2008-08-01

    Before and after World War II, a loose movement within Dutch psychology solidified as a nascent phenomenological psychology. Dutch phenomenological psychologists attempted to generate an understanding of psychology that was based on Husserlian interpretations of phenomenological philosophy. This movement came to a halt in the 1960s, even though it had been exported to North America and elsewhere as "phenomenological psychology." Frequently referred to as the "Utrecht school," most of the activity of the group was centered at Utrecht University. In this article, the authors examine the role played by Johannes Linschoten in both aspects of the development of a phenomenological psychology: its rise in North America and Europe, and its institutional demise. By the time of his early death in 1964, Linschoten had cast considerable doubt on the possibilities of a purely phenomenological psychology. Nonetheless, his own empirical work, especially his 1956 dissertation published in German, can be seen to be a form of empiricism inspired by phenomenology but that clearly distanced itself from the more elitist and esoteric aspects of Dutch phenomenological psychology.

    What does it feel like when one's meaning making is impoverished and threatens to break down? The aim of this study is to show how meaning making is achieved in the context of one's life and how this achievement is often a struggle for the individual. The study reports data from semi-structured interviews with a female participant, which was analysed using interpretative phenomenological analysis (IPA). This paper examines how cultural discourses and conventions are experienced and given meaning by the individual. First, the analysis demonstrates how dominant discourses are used to explain anger and aggression. These include hormones, alcohol, and the influence of past relationships on present action. Second, it examines how the participant's meaning making is often ambiguous and confused, and how she variously accepts and challenges available meanings. Finally, the analysis demonstrates how meaning making can break down and the consequences of this for the individual's sense of self.

    Effects of the secondary electron emission (SEE) phenomenon of metal surface on the multipactor analysis of microwave components are investigated numerically and experimentally in this paper. Both the secondary electron yield (SEY) and the emitted energy spectrum measurements are performed on silver plated samples for accurate description of the SEE phenomenon. A phenomenological probabilistic model based on SEE physics is utilized and fitted accurately to the measured SEY and emitted energy spectrum of the conditioned surface material of microwave components. Specially, the phenomenological probabilistic model is extended to the low primary energy end lower than 20 eV mathematically, since no accuratemore » measurement data can be obtained. Embedding the phenomenological probabilistic model into the Electromagnetic Particle-In-Cell (EM-PIC) method, the electronic resonant multipacting in microwave components can be tracked and hence the multipactor threshold can be predicted. The threshold prediction error of the transformer and the coaxial filter is 0.12 dB and 1.5 dB, respectively. Simulation results demonstrate that the discharge threshold is strongly dependent on the SEYs and its energy spectrum in the low energy end (lower than 50 eV). Multipacting simulation results agree quite well with experiments in practical components, while the phenomenological probabilistic model fit both the SEY and the emission energy spectrum better than the traditionally used model and distribution. The EM-PIC simulation method with the phenomenological probabilistic model for the surface collision simulation has been demonstrated for predicting the multipactor threshold in metal components for space application.« less

  18. Quantum gravity and taoist cosmology: Exploring the ancient origins of phenomenological string theory.

    PubMed

    Rosen, Steven M

    2017-12-01

    This paper carries forward the author's contribution to PBMP's previous special issue on Integral Biomathics (Rosen 2015). In the earlier paper, the crisis in contemporary theoretical physics was described and it was demonstrated that the problem can be addressed effectively only by shifting the foundations of physics from objectivist Cartesian philosophy to phenomenological philosophy. To that end, a phenomenological string theory was proposed based on qualitative topology and hypercomplex numbers. The current presentation takes this further by delving into the ancient Chinese origin of phenomenological string theory. First, we discover a deep connection between the Klein bottle, which is crucial to the theory, and the Ho-t'u, an old Chinese number archetype central to Taoist cosmology. The two structures are seen to mirror each other in expressing the curious psychophysical (phenomenological) action pattern at the heart of microphysics. But tackling the question of quantum gravity requires that a whole family of topological dimensions be brought into play. What we find in engaging with these structures is a closely related family of Taoist forebears that, in concert with their successors, provide a blueprint for cosmic evolution. Whereas conventional string theory accounts for the generation of nature's fundamental forces via a notion of symmetry breaking that is essentially static and thus unable to explain cosmogony successfully, phenomenological/Taoist string theory is guided by the dialectical interplay between symmetry and asymmetry inherent in the principle of synsymmetry. This dynamic concept of cosmic change is elaborated on in the three concluding sections of the paper. Here, a detailed analysis of cosmogony is offered, first in terms of the theory of dimensional development and its Taoist (yin-yang) counterpart, then in terms of the evolution of the elemental force particles through cycles of expansion and contraction in a spiraling universe. The paper closes by considering the role of the analyst per se in the further evolution of the cosmos. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Here, we propose a relationship between the dynamics in the amorphous and crystalline domains during polymer crystallization: the fluctuations of ordering-rate about a material-specific value in the amorphous phase drive those fluctuations associated with the increase in percent crystallinity. This suggests a differential equation that satisfies the three experimentally observed time regimes for the rate of crystal growth. To test this postulated expression, we applied a suite of statistical learning tools to molecular dynamics simulations to extract the relevant phenomenology. This study shows that the proposed relationship holds in the early time regime. It illustrates the effectiveness of soft computingmore » tools in the analysis of coarse-grained simulations in which patterns exist, but may not easily yield to strict quantitative evaluation. This ability assists us in characterizing the critical early time molecular arrangement during the primary nucleation phase of polymer melt crystallization. In addition to supporting the validity of the proposed kinetics expression, the simulations show that (i) the classical nucleation and growth mechanism is active in the early stages of ordering; (ii) the number of nuclei and their masses grow linearly during this early time regime; and (iii) a fixed inter-nuclei distance is established.« less

  1. Choosing phenomenology as a guiding philosophy for nursing research.

    To provide an overview of important methodological considerations that nurse researchers need to adhere to when choosing phenomenology as a guiding philosophy and research method. Phenomenology is a major philosophy and research method in the humanities, human sciences and arts disciplines with a central goal of describing people's experiences. However, many nurse researchers continue to grapple with methodological issues related to their choice of phenomenological method. The author conducted online and manual searches of relevant research books and electronic databases. Using an integrative method, peer-reviewed research and discussion papers published between January 1990 and December 2011 and listed in the CINAHL, Science Direct, PubMed and Google Scholar databases were reviewed. In addition, textbooks that addressed research methodologies such as phenomenology were used. Although phenomenology is widely used today to broaden understanding of human phenomena relevant to nursing practice, nurse researchers often fail to adhere to acceptable scientific and phenomenological standards. Cognisant of these challenges, researchers are expected to indicate in their work the focus of their investigations, designs, and approaches to collecting and analysing data. They are also expected to present their findings in an evocative and expressive manner. Choosing phenomenology requires researchers to understand it as a philosophy, including basic assumptions and tenets of phenomenology as a research method. This awareness enables researchers, especially novices, to make important methodological decisions, particularly those necessary to indicate the study's scientific rigour and phenomenological validity. This paper adds to the discussion of phenomenology as a guiding philosophy for nursing research. It aims to guide new researchers on important methodological decisions they need to make to safeguard their study's scientific rigour and phenomenological validity.

    2017-05-01

    The present paper proposes the use of GIS for the application of the so-called phenomenological approach to the analysis of the seismic behaviour of historical buildings. This approach is based on the awareness that the different masonry building typologies are characterized by different, recurring vulnerabilities. Thus, the observation and classification of the real damage is seen as the first step for recognizing and classifying these vulnerabilities, in order to plan focused preventive interventions. For these purposes, the GIS has proven to be a powerful instrument to collect and manage this type of information on a large number of cases. This paper specifically focuses on the application of the phenomenological approach to the analysis of the seismic behaviour of fortified buildings, including castles, fortresses, citadels, and all the typical historical constructions characterized by the presence of massive towers and defensive walls. The main earthquakes which struck Italy in the last 40 years (up to the recent Central Italy seismic swarm) were taken into consideration and described by means of shake maps. A previously published work has been continued with the addition of new data and some improvements, including a specific symbology for the description of building typologies and conservation status on the maps, the indications of damage levels and the comparison between shake maps in terms of pga and in terms of pseudo-acceleration. The increase in knowledge obtained and the broader frame given by the analysis of the data are here directed to the primary aim of cultural heritage preservation.

    This phenomenological study examines the experiences of students who had been enrolled in an undergraduate women's health issues course where storytelling served as one of the primary teaching and learning tools. Using hermeneutic phenomenology, the investigator explored the perceptions of participants at the conclusion of the course. A purposive sample of 10 students made up the focus group. Themes were explicated and analyzed from interviews until data saturation was reached. Content analysis from focus groups revealed three themes: personalizing learning, participatory learning, and group trust/safe environment. Storytelling provided students with an opportunity to become more actively involved, provided a forum to relate real life examples to concrete didactic data, served as a trigger for information recollection, and made material seem more realistic. The increased discussion and interaction within the classroom setting enabled students to probe alternative views and perspectives in the class room. The use of more diverse teaching tools can enhance the students' experiences in the classroom setting.

    The aim of this paper is to analyse teledildonics from a phenomenological perspective in order to show the possible effects they will have on ourselves and on our society. The new way of using digital technologies is to merge digital activities with our everyday praxes, and there are already devices which enable subjects to be digitally connected in every moment of their lives. Even the most intimate ones are becoming mediated by devices such as teledildonics which digitally provide a tactual stimulation allowing users to have sexual intercourse through them. The efforts made in order to provide such an intertwinement of our everyday lives and digital technologies are evident, but the effects produced by them are not clear at all. This paper will analyse these technologies from a phenomenological perspective in order to understand their effects on the constitution of the subjects and on our society at the intimate level.

    Introduction: There have been considerable changes in the concept and meaning of fatherhood in the past few decades and a lot of studies has down in this area, but there is no information about fathering and fatherhood from Iranian perspective, thus present study designed to explore the men’s understanding of fathering and paternal role during their first year of transition to parenthood. Method: This phenomenological study included accounts of 17 Iranian fathers, who had experienced fathering for the first time. Data was analyzed using the Interpretative Phenomenological Analysis (IPA) approach. Results: The results reveal that a father is a man who reproduces a child and accepts the responsibility for supporting his family as the fulcrum. A father is a good-tempered, faithful, patient and hardworking man with essential knowledge and proficiency. A father should accept his role as the father. He is also expected to participate actively in dealing with family daily issues, value and promote the health and well-being of his children, and have skills of self-management and self-care. Conclusion: Iranian fathers not only committed to play their traditional roles and responsibilities, but also welcome new roles such as constantly being with their children and providing emotional support to them.

The phenomenon is to study obesity in infertile women candidates for assisted reproduction treatment. Obese infertile women subject to assisted reproduction treatment perceive their difficulty losing weight is closely associated with infertility. Most patients had social feelings of worthlessness, sadness, worthlessness, and family rejection. The inability to obtain a steady weight loss is regarded as a minor frustration that sterility. It is very important to perform intensive, multidisciplinary labor, which is focused on concepts associated with psychological distress, such as: management of depression by sterility, control of anxiety and stress, control of social pressures and management of the illusion of motherhood.

    We study the seven-dimensional Minimal Supersymmetric Standard Model (MSSM7) with the new GAMBIT software framework, with all parameters defined at the weak scale. Our analysis significantly extends previous weak-scale, phenomenological MSSM fits, by adding more and newer experimental analyses, improving the accuracy and detail of theoretical predictions, including dominant uncertainties from the Standard Model, the Galactic dark matter halo and the quark content of the nucleon, and employing novel and highly-efficient statistical sampling methods to scan the parameter space. We find regions of the MSSM7 that exhibit co-annihilation of neutralinos with charginos, stops and sbottoms, as well as models that undergo resonant annihilation via both light and heavy Higgs funnels. We find high-likelihood models with light charginos, stops and sbottoms that have the potential to be within the future reach of the LHC. Large parts of our preferred parameter regions will also be accessible to the next generation of direct and indirect dark matter searches, making prospects for discovery in the near future rather good.

    Lithium-ion cells are commonly used in a multicell configuration in power devices and electric vehicles, making the cell-to-cell variation (CtCV) a key factor to consider in system design and management. Previous studies on CtCV have two major limitations: the number of cells is usually less than one hundred, and the cells are usually commercial cells already subjected to cell-screenings. In this article, we first make a statistical analysis on the CtCV of 5473 fresh cells from an automotive battery manufacturer before the cell-screening process. Secondly, 198 cells are randomly selected from these 5473 cells and the rate dependence of the CtCV is examined, focusing on the correlations of capacity versus weight and capacity versus resistance, corresponding to thermodynamic and kinetic factors, respectively. The rate dependence of these two correlations is explained from a phenomenological model. Finally, eight cells from the 198 cells are further characterized with electrochemical impedance spectroscopy method to elucidate the kinetic origins of the CtCV.

    2007-07-21

    While recently derived continuum mesoscopic equations successfully bridge the gap between microscopic and macroscopic physics, so far they have been derived only for simple lattice models. In this paper, general deterministic continuum mesoscopic equations are derived rigorously via nonequilibrium statistical mechanics to account for multiple interacting surface species and multiple processes on multiple site types and/or different crystallographic planes. Adsorption, desorption, reaction, and surface diffusion are modeled. It is demonstrated that contrary to conventional phenomenological continuum models, microscopic physics, such as the interaction potential, determines the final form of the mesoscopic equation. Models of single component diffusion and binary diffusion of interacting particles on single-type site lattice and of single component diffusion on complex microporous materials' lattices consisting of two types of sites are derived, as illustrations of the mesoscopic framework. Simplification of the diffusion mesoscopic model illustrates the relation to phenomenological models, such as the Fickian and Maxwell-Stefan transport models. It is demonstrated that the mesoscopic equations are in good agreement with lattice kinetic Monte Carlo simulations for several prototype examples studied.

    Understanding the behavior (and failure) of dielectric insulators experiencing extreme electric fields is critical to the operation of present and emerging electrical and electronic devices. Despite its importance, the development of a predictive theory of dielectric breakdown has remained a challenge, owing to the complex multiscale nature of this process. We focus on the intrinsic dielectric breakdown field of insulators—the theoretical limit of breakdown determined purely by the chemistry of the material, i.e., the elements the material is composed of, the atomic-level structure, and the bonding. Starting from a benchmark dataset (generated from laborious first principles computations) of the intrinsicmore » dielectric breakdown field of a variety of model insulators, simple predictive phenomenological models of dielectric breakdown are distilled using advanced statistical or machine learning schemes, revealing key correlations and analytical relationships between the breakdown field and easily accessible material properties. Lastly, the models are shown to be general, and can hence guide the screening and systematic identification of high electric field tolerant materials.« less

    Understanding the behavior (and failure) of dielectric insulators experiencing extreme electric fields is critical to the operation of present and emerging electrical and electronic devices. Despite its importance, the development of a predictive theory of dielectric breakdown has remained a challenge, owing to the complex multiscale nature of this process. We focus on the intrinsic dielectric breakdown field of insulators—the theoretical limit of breakdown determined purely by the chemistry of the material, i.e., the elements the material is composed of, the atomic-level structure, and the bonding. Starting from a benchmark dataset (generated from laborious first principles computations) of the intrinsicmore » dielectric breakdown field of a variety of model insulators, simple predictive phenomenological models of dielectric breakdown are distilled using advanced statistical or machine learning schemes, revealing key correlations and analytical relationships between the breakdown field and easily accessible material properties. Lastly, the models are shown to be general, and can hence guide the screening and systematic identification of high electric field tolerant materials.« less

  1. A Power Experience: A Phenomenological Study of Interprofessional Education.

    PubMed

    Engel, Joyce; Prentice, Dawn; Taplay, Karyn

    The purpose of this supplementary analysis of a hermeneutic phenomenological study of the experience of interprofessional collaboration for nursing and medical students was to explore the experience of power that was threaded throughout the original study. Seventeen students participated in guided, face-to-face conversations in the original study (Prentice, Engel, Taplay, & Stobbe, 2014). Through the processes of deductive analysis and inductive reasoning, 2 themes of power emerged from these research conversations: (a) complicated knowledge is power and (b) the power and silence of intimidation. These themes suggest that power and power differentials are significant factors in student interactions in interprofessional learning and have the potential to adversely affect these interactions. Students' perceptions of power need to be taken into account and addressed when planning and implementing interprofessional education events. Copyright © 2016 Elsevier Inc. All rights reserved.

  2. Slaughtering for a living: A hermeneutic phenomenological perspective on the well-being of slaughterhouse employees

    2016-01-01

    Slaughterhouses constitute a unique work setting exposing employees to particular physical and psychological health challenges. Research that focuses on the well-being of slaughterhouse employees is limited, and the aim of this study was to explore their well-being by conducting a hermeneutic phenomenological study of specifically the slaughterfloor employees’ work-life experiences. The study was conducted in a South African commercial abattoir setting. Thirteen slaughterfloor employees and two managers of the slaughterfloor section participated in unstructured interviews. A hermeneutic phenomenological approach to data analysis was adopted following the stages of a naïve reading, a structural thematic analysis, and a comprehensive understanding. Data analysis resulted in four process-related themes representing the different stages of becoming a slaughterer, (mal)adjusting to slaughter work, coping with and maintaining the work, and living with the psycho-social consequences of slaughter work. Results facilitate an understanding of how employee well-being manifests in each of these stages of being a slaughterfloor employee. The risk potential of employees suffering from post-traumatic stress syndrome was evident throughout the stages of being a slaughterfloor employee and offers a useful diagnostic framework to facilitate employee well-being assistance. Slaughterhouse management should develop a holistic focus addressing employee well-being needs evident in each of the stages of being a slaughter worker and by extending well-being interventions to the broader communities that the slaughterhouse functions in.

    The study considers the origins of Karl Jaspers' phenomenology. What did phenomenology mean to Jaspers and what was his personal perspective? What metaphors did he associate with it? This paper describes his phenomenological method by using the metaphors of histology and the X-ray. This perspective enables a better understanding, not only of the origins and essence of his phenomenology but also of its value for Jaspers himself. In Jaspers' daily life, he would have been familiar with microscopes and X-ray machines.

    2017-10-01

    This paper revisits the debate about cognitive phenomenology. It elaborates, defends, and improves on our earlier proposal for resolving that debate, according to which the test for irreducible phenomenology is the presence of explanatory gaps. After showing how proposals like ours have been misunderstood or misused by others, we deploy our operationalization to argue that the correct way to align the debate over cognitive phenomenology is not between sensory and (alleged) cognitive phenomenology, but rather between non-conceptual and (alleged) conceptual or propositional phenomenology. In doing so we defend three varieties of non-sensory (amodal) 1 non-conceptual phenomenology: valence, a sense of approximate number, and a sense of elapsed time. Copyright © 2017 Elsevier Inc.

    2017-05-01

    In this article, we describe our approach and philosophical methodology of teaching and doing phenomenology. The human science seminar that we offer involves participants in the primary phenomenological literature as well as in a variety of carefully engaged writing exercises. Each seminar participant selects a personal phenomenological project that aims at producing a publishable research paper. We show how the qualitative methodology of hermeneutic phenomenology requires of its practitioner a sensitivity and attitudinal disposition that has to be internalized and that cannot be captured in a procedural or step-by-step program. Our experience is that seminar participants become highly motivated and committed to their phenomenological project while involved in the rather intense progression of lectures, workshop activities, readings, and discussions.

    Well established theory can be used to combine single-phenomenology hypothesis tests into a multi-phenomenology event screening hypothesis test (Fisher's and Tippett's tests). Commonly used standard error in Ms:mb event screening hypothesis test is not fully consistent with physical basis. Improved standard error - Better agreement with physical basis, and correctly partitions error to include Model Error as a component of variance, correctly reduces station noise variance through network averaging. For 2009 DPRK test - Commonly used standard error 'rejects' H0 even with better scaling slope ({beta} = 1, Selby et al.), improved standard error 'fails to rejects' H0.

    The manipulation of thermal hysteresis in Ni-Mn-Ga Heusler alloys with coupled magnetostructural phase transition is studied theoretically using the Landau theory, including magnetic, elastic and crystal lattice modulation order parameters as well as an external magnetic field. It is shown that for the assigned combination of phenomenological parameters, in the phase diagrams, the Austenite-Martensite first-order phase transition has a finite (critical) point in which the thermal hysteresis is disappeared. Moreover, this point depends on the relation between modulation and elastic constants as well as on the magnetic field. Obtained results have been compared with other theoretical end experimental data.

    We investigate the phenomenological viability of a recently proposed class of composite dark matter models where the relic density is determined by 3 →2 number-changing processes in the dark sector. Here the pions of the strongly interacting field theory constitute the dark matter particles. By performing a consistent next-to-leading- and next-to-next-to-leading-order chiral perturbative investigation we demonstrate that the leading-order analysis cannot be used to draw conclusions about the viability of the model. We further show that higher-order corrections substantially increase the tension with phenomenological constraints challenging the viability of the simplest realization of the strongly interacting massive particle paradigm.

  13. Critical appraisal of rigour in interpretive phenomenological nursing research.

    PubMed

    de Witt, Lorna; Ploeg, Jenny

    2006-07-01

    This paper reports a critical review of published nursing research for expressions of rigour in interpretive phenomenology, and a new framework of rigour specific to this methodology is proposed. The rigour of interpretive phenomenology is an important nursing research methods issue that has direct implications for the legitimacy of nursing science. The use of a generic set of qualitative criteria of rigour for interpretive phenomenological studies is problematic because it is philosophically inconsistent with the methodology and creates obstacles to full expression of rigour in such studies. A critical review was conducted of the published theoretical interpretive phenomenological nursing literature from 1994 to 2004 and the expressions of rigour in this literature identified. We used three sources to inform the derivation of a proposed framework of expressions of rigour for interpretive phenomenology: the phenomenological scholar van Manen, the theoretical interpretive phenomenological nursing literature, and Madison's criteria of rigour for hermeneutic phenomenology. The nursing literature reveals a broad range of criteria for judging the rigour of interpretive phenomenological research. The proposed framework for evaluating rigour in this kind of research contains the following five expressions: balanced integration, openness, concreteness, resonance, and actualization. Balanced integration refers to the intertwining of philosophical concepts in the study methods and findings and a balance between the voices of study participants and the philosophical explanation. Openness is related to a systematic, explicit process of accounting for the multiple decisions made throughout the study process. Concreteness relates to usefulness for practice of study findings. Resonance encompasses the experiential or felt effect of reading study findings upon the reader. Finally, actualization refers to the future realization of the resonance of study findings. Adoption of this or similar frameworks of expressions of rigour could help to preserve the integrity and legitimacy of interpretive phenomenological nursing research.

    Image sequences of the surface of disordered layers of porous medium (paper) obtained under noncoherent and coherent illumination during capillary rise of a liquid are analyzed. As a result, principles that govern the critical behavior of the interface between liquid and gaseous phases during its pinning are established. By a cumulant analysis of speckle-modulated images of the surface and by the statistical analysis of binarized difference images of the surface under noncoherent illumination, it is shown that the macroscopic dynamics of the interface at the stage of pinning is mainly controlled by the power law dependence of the appearance ratemore » of local instabilities (avalanches) of the interface on the critical parameter, whereas the growth dynamics of the local instabilities is controlled by the diffusion of a liquid in a layer and weakly depends on the critical parameter. A phenomenological model is proposed for the macroscopic dynamics of the phase interface for interpreting experimental data. The values of critical indices are determined that characterize the samples under test within this model. These values are compared with the results of numerical simulation for discrete models of directed percolation corresponding to the Kardar-Parisi-Zhang equation.« less

    PubMed

    Walcott, G; Hickling, F W

    2013-01-01

    The object of this study is to establish the correlates of the phenomenology of conflict and power management in the Jamaican population. A total of 1506 adult individuals were sampled from 2150 households using a stratified sampling method and assessed using the 12 questions of the Jamaica Personality Disorder Inventory (JPDI) on the phenomenology of conflict and power management that are grouped into the psychological features of aggressive social behaviour, unlawful behaviour, socially unacceptable behaviour and financial transgressive behaviour. The database of responses to the demographic and JPDI questionnaires was created and analysed using the Statistical Package for the Social Sciences (SPSS) version 17. Of the national population sampled, 69.1% denied having any phenomenological symptoms of abnormal power management relations while 30.9% of the population admitted to having some degree of conflict and power management, ranging from mild (10.3%), to moderate (17.1), or severe (3.5%). There were 46.55% of the population which had problems with aggressive social behaviour, 9.33% had problems with unlawful behaviour, 9.58% had problems with unacceptable social behaviour and 37.74% had problems with financial transgressive behaviour. Significant gender and socio-economic class patterns for conflict and power management were revealed. This pattern of conflict and power management behaviour is critical in understanding the distinction between normal and abnormal expression of these emotions and actions. Nearly one-third of the sample population ` studied reported problems with conflict, abnormal power and authority management, impulse control and serious aggressive and transgressive behaviour.

  20. Virtual Model Validation of Complex Multiscale Systems: Applications to Nonlinear Elastostatics

    DOE Office of Scientific and Technical Information (OSTI.GOV)

    Oden, John Tinsley; Prudencio, Ernest E.; Bauman, Paul T.

    We propose a virtual statistical validation process as an aid to the design of experiments for the validation of phenomenological models of the behavior of material bodies, with focus on those cases in which knowledge of the fabrication process used to manufacture the body can provide information on the micro-molecular-scale properties underlying macroscale behavior. One example is given by models of elastomeric solids fabricated using polymerization processes. We describe a framework for model validation that involves Bayesian updates of parameters in statistical calibration and validation phases. The process enables the quanti cation of uncertainty in quantities of interest (QoIs) andmore » the determination of model consistency using tools of statistical information theory. We assert that microscale information drawn from molecular models of the fabrication of the body provides a valuable source of prior information on parameters as well as a means for estimating model bias and designing virtual validation experiments to provide information gain over calibration posteriors.« less

  1. Initial Systematic Investigations of the Weakly Coupled Free Fermionic Heterotic String Landscape Statistics

    2011-12-01

    A C++ framework was constructed with the explicit purpose of systematically generating string models using the Weakly Coupled Free Fermionic Heterotic String (WCFFHS) method. The software, optimized for speed, generality, and ease of use, has been used to conduct preliminary systematic investigations of WCFFHS vacua. Documentation for this framework is provided in the Appendix. After an introduction to theoretical and computational aspects of WCFFHS model building, a study of ten-dimensional WCFFHS models is presented. Degeneracies among equivalent expressions of each of the known models are investigated and classified. A study of more phenomenologically realistic four-dimensional models based on the well known "NAHE" set is then presented, with statistics being reported on gauge content, matter representations, and space-time supersymmetries. The final study is a parallel to the NAHE study in which a variation of the NAHE set is systematically extended and examined statistically. Special attention is paid to models with "mirroring"---identical observable and hidden sector gauge groups and matter representations.

  5. Age differences in autobiographical memory across the adult lifespan: older adults report stronger phenomenology.

    PubMed

    Luchetti, Martina; Sutin, Angelina R

    2018-01-01

    As an individual's life story evolves across adulthood, the subjective experience (phenomenology) of autobiographical memory likely changes. In addition to age at retrieval, both the recency of the memory and the age when a memory is formed may be particularly important to its phenomenology. The present work examines the effect of three temporal factors on phenomenology ratings: (a) age of the participant, (b) age at the event reported in the memory, and (c) memory age (recency). A large sample of Americans (N = 1120), stratified by chronological age, recalled and rated two meaningful memories, a Turning Point and an Early Childhood Memory. Ratings of phenomenology (e.g., vividness of turning points) were higher among older adults compared to younger adults. Memories of events from the reminiscence bump were more positive in valence than events from other time periods but did not differ on other phenomenological dimensions; recent memories had stronger phenomenology than remote memories. In contrast to phenomenology, narrative content was generally unrelated to participant age, age at the event, or memory age. Overall, the findings indicate age-related differences in how meaningful memories are re-experienced.

  6. Phenomenological Characteristics of Future Thinking in Alzheimer's Disease.

    2018-05-11

    This study investigates phenomenological reliving of future thinking in Alzheimer's disease (AD) patients and matched controls. All participants were asked to imagine in detail a future event, and afterward, were asked to rate phenomenological characteristics of their future thinking. As compared to controls, AD participants showed poor rating for reliving, travel in time, visual imagery, auditory imagery, language, and spatiotemporal specificity. However, no significant differences were observed between both groups in emotion and importance of future thinking. Results also showed lower rating for visual imagery relative to remaining phenomenological features in AD participants compared to controls; conversely, these participants showed higher ratings for emotion and importance of future thinking. AD seems to compromise some phenomenological characteristics of future thinking, especially, visual imagery; however, other phenomenological characteristics, such as emotion, seem to be relatively preserved in these populations. By highlighting the phenomenological experience of future thinking in AD, our paper opens a unique window into the conscious experience of the future in AD patients.

  7. Kinetics of low-temperature transitions and a reaction rate theory from non-equilibrium distributions

    Aquilanti, Vincenzo; Coutinho, Nayara Dantas

    2017-01-01

    This article surveys the empirical information which originated both by laboratory experiments and by computational simulations, and expands previous understanding of the rates of chemical processes in the low-temperature range, where deviations from linearity of Arrhenius plots were revealed. The phenomenological two-parameter Arrhenius equation requires improvement for applications where interpolation or extrapolations are demanded in various areas of modern science. Based on Tolman's theorem, the dependence of the reciprocal of the apparent activation energy as a function of reciprocal absolute temperature permits the introduction of a deviation parameter d covering uniformly a variety of rate processes, from those where quantum mechanical tunnelling is significant and d < 0, to those where d > 0, corresponding to the Pareto–Tsallis statistical weights: these generalize the Boltzmann–Gibbs weight, which is recovered for d = 0. It is shown here how the weights arise, relaxing the thermodynamic equilibrium limit, either for a binomial distribution if d > 0 or for a negative binomial distribution if d < 0, formally corresponding to Fermion-like or Boson-like statistics, respectively. The current status of the phenomenology is illustrated emphasizing case studies; specifically (i) the super-Arrhenius kinetics, where transport phenomena accelerate processes as the temperature increases; (ii) the sub-Arrhenius kinetics, where quantum mechanical tunnelling propitiates low-temperature reactivity; (iii) the anti-Arrhenius kinetics, where processes with no energetic obstacles are rate-limited by molecular reorientation requirements. Particular attention is given for case (i) to the treatment of diffusion and viscosity, for case (ii) to formulation of a transition rate theory for chemical kinetics including quantum mechanical tunnelling, and for case (iii) to the stereodirectional specificity of the dynamics of reactions strongly hindered by the increase of temperature.

  9. Multiscale modeling of brain dynamics: from single neurons and networks to mathematical tools.

    PubMed

    Siettos, Constantinos; Starke, Jens

    2016-09-01

    The extreme complexity of the brain naturally requires mathematical modeling approaches on a large variety of scales; the spectrum ranges from single neuron dynamics over the behavior of groups of neurons to neuronal network activity. Thus, the connection between the microscopic scale (single neuron activity) to macroscopic behavior (emergent behavior of the collective dynamics) and vice versa is a key to understand the brain in its complexity. In this work, we attempt a review of a wide range of approaches, ranging from the modeling of single neuron dynamics to machine learning. The models include biophysical as well as data-driven phenomenological models. The discussed models include Hodgkin-Huxley, FitzHugh-Nagumo, coupled oscillators (Kuramoto oscillators, Rössler oscillators, and the Hindmarsh-Rose neuron), Integrate and Fire, networks of neurons, and neural field equations. In addition to the mathematical models, important mathematical methods in multiscale modeling and reconstruction of the causal connectivity are sketched. The methods include linear and nonlinear tools from statistics, data analysis, and time series analysis up to differential equations, dynamical systems, and bifurcation theory, including Granger causal connectivity analysis, phase synchronization connectivity analysis, principal component analysis (PCA), independent component analysis (ICA), and manifold learning algorithms such as ISOMAP, and diffusion maps and equation-free techniques.

    : Early interruption of maternal breastfeeding is a public health problem in developed and developing societies, and social gender constructions and social inequalities between men and women contribute to the phenomenon's complexity. The article reflects on the experiences of fathers and mothers with the reconfiguration of bodies, roles, and daily routines involved in breastfeeding. This was a qualitative study with an interpretative phenomenological focus and gender perspective in couples whose children were less than six months old, who were breastfeeding or had breastfed and agreed to participate voluntarily. A phenomenological analysis was performed on "units of meaning" in the four dimensions explored by phenomenology: corporality, time, space, and relations. Among the mothers, the analysis identified the existence of conflict and guilt associated with breastfeeding; the mothers' need for sleep and rest made them experience breastfeeding as a role that overburdened them in their daily lives. Their spouses showed limitations resulting from social constructs of masculinity, in becoming involved with the infant and supporting the mother to continue breastfeeding. It is thus urgent for health professionals to discuss the processes of motherhood and fatherhood in relation to infants and breastfeeding, from an inclusive gender perspective that assigns importance to the mother-infant dyad, with special emphasis on the mother-infant-father triad.

  14. Differentiating between descriptive and interpretive phenomenological research approaches.

    To provide insight into how descriptive and interpretive phenomenological research approaches can guide nurse researchers during the generation and application of knowledge. Phenomenology is a discipline that investigates people's experiences to reveal what lies 'hidden' in them. It has become a major philosophy and research method in the humanities, human sciences and arts. Phenomenology has transitioned from descriptive phenomenology, which emphasises the 'pure' description of people's experiences, to the 'interpretation' of such experiences, as in hermeneutic phenomenology. However, nurse researchers are still challenged by the epistemological and methodological tenets of these two methods. The data came from relevant online databases and research books. A review of selected peer-reviewed research and discussion papers published between January 1990 and December 2013 was conducted using CINAHL, Science Direct, PubMed and Google Scholar databases. In addition, selected textbooks that addressed phenomenology as a philosophy and as a research methodology were used. Evidence from the literature indicates that most studies following the 'descriptive approach' to research are used to illuminate poorly understood aspects of experiences. In contrast, the 'interpretive/hermeneutic approach' is used to examine contextual features of an experience in relation to other influences such as culture, gender, employment or wellbeing of people or groups experiencing the phenomenon. This allows investigators to arrive at a deeper understanding of the experience, so that caregivers can derive requisite knowledge needed to address such clients' needs. Novice nurse researchers should endeavour to understand phenomenology both as a philosophy and research method. This is vitally important because in-depth understanding of phenomenology ensures that the most appropriate method is chosen to implement a study and to generate knowledge for nursing practice. This paper adds to the current debate on why it is important for nurse researchers to clearly understand phenomenology as a philosophy and research method before embarking on a study. The paper guides novice researchers on key methodological decisions they need to make when using descriptive or interpretive phenomenological research approaches.

  15. Statistical Analyses of Hydrophobic Interactions: A Mini-Review

    Pratt, Lawrence R.; Chaudhari, Mangesh I.; Rempe, Susan B.

    2016-07-14

    Here this review focuses on the striking recent progress in solving for hydrophobic interactions between small inert molecules. We discuss several new understandings. First, the inverse temperature phenomenology of hydrophobic interactions, i.e., strengthening of hydrophobic bonds with increasing temperature, is decisively exhibited by hydrophobic interactions between atomic-scale hard sphere solutes in water. Second, inclusion of attractive interactions associated with atomic-size hydrophobic reference cases leads to substantial, nontrivial corrections to reference results for purely repulsive solutes. Hydrophobic bonds are weakened by adding solute dispersion forces to treatment of reference cases. The classic statistical mechanical theory for those corrections is not accuratemore » in this application, but molecular quasi-chemical theory shows promise. Lastly, because of the masking roles of excluded volume and attractive interactions, comparisons that do not discriminate the different possibilities face an interpretive danger.« less

  16. Statistical mechanics of self-driven Carnot cycles.

    Smith, E

    1999-10-01

    The spontaneous generation and finite-amplitude saturation of sound, in a traveling-wave thermoacoustic engine, are derived as properties of a second-order phase transition. It has previously been argued that this dynamical phase transition, called "onset," has an equivalent equilibrium representation, but the saturation mechanism and scaling were not computed. In this work, the sound modes implementing the engine cycle are coarse-grained and statistically averaged, in a partition function derived from microscopic dynamics on criteria of scale invariance. Self-amplification performed by the engine cycle is introduced through higher-order modal interactions. Stationary points and fluctuations of the resulting phenomenological Lagrangian are analyzed and related to background dynamical currents. The scaling of the stable sound amplitude near the critical point is derived and shown to arise universally from the interaction of finite-temperature disorder, with the order induced by self-amplification.

    2011-08-01

    A new statistical model of the charge transport in colloidal quantum dot arrays is proposed. It takes into account Coulomb blockade forbidding multiple occupancy of nanocrystals and the influence of energetic disorder of interdot space. The model explains power-law current transients and the presence of the memory effect. The fractional differential analogue of the Ohm law is found phenomenologically for nanocrystal arrays. The model combines ideas that were considered as conflicting by other authors: the Scher-Montroll idea about the power-law distribution of waiting times in localized states for disordered semiconductors is applied taking into account Coulomb blockade; Novikov's condition about the asymptotic power-law distribution of time intervals between successful current pulses in conduction channels is fulfilled; and the carrier injection blocking predicted by Ginger and Greenham (2000 J. Appl. Phys. 87 1361) takes place.

    This study explored the phenomenon of the lived experience of choosing a healthy lifestyle based upon an organic diet as seen from the perspective of the young adult. Interviews were collected in Sweden and analyzed using the descriptive phenomenological psychological research method. The results showed the general psychological structure of the phenomenon, comprising four constituents: (1) the lived body as the starting point for life exploration, (2) a narrative self through emotional-relational food memories, (3) a conscious life strategy for well-being and vitality, and (4) a personal set of values in relation to ethical standards. The results provide plausible insights into the intricate relation between psychological meaning and the natural world. PMID:23769652

We add to this the current knowledge on non-strange dense matter, including its uncertainties, to conclude that the interaction between $$\\Lambda$$s and dense matter has to become repulsive at densities below three times the nuclear saturation density.« less

    2008-01-01

    In this paper, we suggest that affect meets the traditional definition of “cognition” such that the affect–cognition distinction is phenomenological, rather than ontological. We review how the affect–cognition distinction is not respected in the human brain, and discuss the neural mechanisms by which affect influences sensory processing. As a result of this sensory modulation, affect performs several basic “cognitive” functions. Affect appears to be necessary for normal conscious experience, language fluency, and memory. Finally, we suggest that understanding the differences between affect and cognition will require systematic study of how the phenomenological distinction characterising the two comes about, and why such a distinction is functional.

    We have determined the quantum confinement induced shifts in energy of band edges and band gap with respect to size of ZnSe spherical quantum dot employing an effective confinement potential model developed in our earlier communication "arXiv:1705.10343". We have also performed phenomenological analysis of our theoretical results in comparison with available experimental data and observe a very good agreement in this regard. Phenomenological success achieved in this regard confirms validity of the confining potential model as well as signifies the capability and applicability of the ansatz for the effective confining potential to have reasonable information in the study of real nano-structured spherical systems.

    The molecular-level details of crystallization remain unclear for many systems. Previous work has speculated on the phenomenological similarities between molecular crystallization and protein folding. Here we demonstrate that molecular crystallization can involve funnel-shaped potential energy landscapes through a detailed analysis of mixed gas hydrate nucleation, a prototypical multicomponent crystallization process. Through this, we contribute both: (i) a powerful conceptual framework for exploring and rationalizing molecular crystallization, and (ii) an explanation of phenomenological similarities between protein folding and crystallization. Such funnel-shaped potential energy landscapes may be typical of broad classes of molecular ordering processes, and can provide a new perspective for both studying and understanding these processes.

    2016-12-01

    We perform a multi-phenomenological analysis of the massive near-surface chemical explosions that occurred in Tianjin, China on 12 August 2015. A recent assessment of these events was performed by Zhao et al. (2016) using local (< 100 km) seismic data. This study considers a regional assessment of the same sequence in the absence of having any local data. We provide additional insight by combining regional seismic analysis with the use of infrasound signals and an assessment of the event crater. Event locations using infrasound signals recorded at Korean and IMS arrays are estimated based on the Bayesian Infrasonic Source Location (BISL) method (Modrak et al., 2010), and improved with azimuthal corrections using a raytracing (Blom and Waxler, 2012) and the Ground-to-Space (G2S) atmospheric models (Drob et al., 2003). The location information provided from the infrasound signals is then merged with the regional seismic arrivals to produce a joint event location. The yields of the events are estimated from seismic and infrasonic observations. Seismic waveform envelope method (Pasyanos et al., 2012) including the free surface effect (Pasyanos and Ford, 2015) is applied to regional seismic signals. Waveform inversion method (Kim and Rodgers, 2016) is used for infrasound signals. A combination of the seismic and acoustic signals can provide insights on the energy partitioning and break the tradeoffs between the yield and the depth/height of explosions, resulting in a more robust estimation of event yield. The yield information from the different phenomenologies are combined through the use of likelihood functions.

  5. Living With Chronic Lower Pulmonary Disease

    Pooler, Charlotte

    2014-01-01

    In this article, I present a phenomenological study of individuals’ experiences of living with moderate to very severe chronic lower pulmonary disease (chronic obstructive pulmonary disease, asthma, or both). Phenomenology is a philosophy, distinct from descriptive or thematic research, which is useful as a foundation for scientific inquiry. In this study, I used the lens of Merleau-Ponty to understand and interpret participants’ experiences of living with pulmonary disease, and the approach of van Manen for analysis. I conclude that in chronic pulmonary disease, awareness of breathing and the body is experienced in the sounds, sensations, and signals of breathing and the body, and in the experiences of the body-in-the-world. Central themes of being-in-the-world from the study describe the disruption of the embodied phenomenological self: Participants experienced slowing down, doing less, and having to stop due to shortness of breath. Both chronic and acute dyspnea were prevalent and the taken-for-granted aspects of daily activities were disrupted. Findings of this study have implications for public and patient education, and opportunities for integration of experiential aspects within nursing education and practice. PMID:28462289

    Individuals with ADHD and comorbid hoarding disorder are vulnerable to severe consequences from hoarding symptoms. Despite this, and the early onset of hoarding disorder, the nature of hoarding symptoms in children with comorbid ADHD is unknown. We therefore explored the phenomenology of hoarding symptoms among ten 8-12year olds with ADHD and clinically significant hoarding symptoms through parental perceptions. Parents completed in-depth semi-structured interviews. The data was analyzed using Interpretative Phenomenological Analysis. Six superordinate themes were identified: emotional distress; parental avoidance and accommodating behaviors; family impacts of hoarding; excessive acquisition and saving; executive functioning; parental insight and intervention. In contrast to previous suggestions that emotional distress was not associated with hoarding in ADHD, these findings highlight that emotional distress appeared to be core to the hoarding disorder profile of the present sample of children with ADHD. This has important implications for health practitioners who may consider conceptualizing, assessing, and treating hoarding symptoms in children with comorbid ADHD using a cognitive behavioral model of hoarding disorder.

    2015-08-01

    Qualitative methods such as phenomenology and grounded theory have been valuable tools in studying public health problems. A description and comparison of these methods. Phenomenology emphasises an inside perspective in form of consciousness and subjectively lived experiences, whereas grounded theory emanates from the idea that interactions between people create new insights and knowledge. Fundamental aspects of phenomenology include life world, consciousness, phenomenological reduction and essence. Significant elements in grounded theory are coding, categories and core categories, which develop a theory. There are differences in the philosophical approach, the name of the concept and the systematic tools between the methods. Thus, the phenomenological method is appropriate when studying emotional and existential research problems, and grounded theory is a method more suited to investigate processes. © 2015 the Nordic Societies of Public Health.

    Historically, mental health research has been strongly influenced by the underlying positivism of the quantitative paradigm. Quantitative research dominates scientific enquiry and contributes significantly to understanding our natural world. It has also greatly benefitted the medical model of healthcare. However, the more literary, silent, qualitative approach is gaining prominence in human sciences research, particularly mental healthcare research. To examine the qualitative methodological assumptions of phenomenology to illustrate the benefits to mental health research of studying the experiences of people with mental illness. Phenomenology is well positioned to ask how people with mental illness reflect on their experiences. Phenomenological research is congruent with the principles of contemporary mental healthcare, as person-centred care is favoured at all levels of mental healthcare, treatment, service and research. Phenomenology is a highly appropriate and suitable methodology for mental health research, given it includes people's experiences and enables silent voices to be heard. This overview of the development of phenomenology informs researchers new to phenomenological enquiry. ©2017 RCN Publishing Company Ltd. All rights reserved.

  12. Beyond Descartes and Newton: Recovering life and humanity.

    PubMed

    Kauffman, Stuart A; Gare, Arran

    2015-12-01

    Attempts to 'naturalize' phenomenology challenge both traditional phenomenology and traditional approaches to cognitive science. They challenge Edmund Husserl's rejection of naturalism and his attempt to establish phenomenology as a foundational transcendental discipline, and they challenge efforts to explain cognition through mainstream science. While appearing to be a retreat from the bold claims made for phenomenology, it is really its triumph. Naturalized phenomenology is spearheading a successful challenge to the heritage of Cartesian dualism. This converges with the reaction against Cartesian thought within science itself. Descartes divided the universe between res cogitans, thinking substances, and res extensa, the mechanical world. The latter won with Newton and we have, in most of objective science since, literally lost our mind, hence our humanity. Despite Darwin, biologists remain children of Newton, and dream of a grand theory that is epistemologically complete and would allow lawful entailment of the evolution of the biosphere. This dream is no longer tenable. We now have to recognize that science and scientists are within and part of the world we are striving to comprehend, as proponents of endophysics have argued, and that physics, biology and mathematics have to be reconceived accordingly. Interpreting quantum mechanics from this perspective is shown to both illuminate conscious experience and reveal new paths for its further development. In biology we must now justify the use of the word "function". As we shall see, we cannot prestate the ever new biological functions that arise and constitute the very phase space of evolution. Hence, we cannot mathematize the detailed becoming of the biosphere, nor write differential equations for functional variables we do not know ahead of time, nor integrate those equations, so no laws "entail" evolution. The dream of a grand theory fails. In place of entailing laws, a post-entailing law explanatory framework is proposed in which Actuals arise in evolution that constitute new boundary conditions that are enabling constraints that create new, typically unprestatable, Adjacent Possible opportunities for further evolution, in which new Actuals arise, in a persistent becoming. Evolution flows into a typically unprestatable succession of Adjacent Possibles. Given the concept of function, the concept of functional closure of an organism making a living in its world, becomes central. Implications for patterns in evolution include historical reconstruction, and statistical laws such as the distribution of extinction events, or species per genus, and the use of formal cause, not efficient cause, laws.

    2015-08-01

    The Kepler AutoRegressive Planet Search (KARPS) project uses statistical methodology associated with autoregressive (AR) processes to model Kepler lightcurves in order to improve exoplanet transit detection in systems with high stellar variability. We also introduce a planet-search algorithm to detect transits in time-series residuals after application of the AR models. One of the main obstacles in detecting faint planetary transits is the intrinsic stellar variability of the host star. The variability displayed by many stars may have autoregressive properties, wherein later flux values are correlated with previous ones in some manner. Auto-Regressive Moving-Average (ARMA) models, Generalized Auto-Regressive Conditional Heteroskedasticity (GARCH), and related models are flexible, phenomenological methods used with great success to model stochastic temporal behaviors in many fields of study, particularly econometrics. Powerful statistical methods are implemented in the public statistical software environment R and its many packages. Modeling involves maximum likelihood fitting, model selection, and residual analysis. These techniques provide a useful framework to model stellar variability and are used in KARPS with the objective of reducing stellar noise to enhance opportunities to find as-yet-undiscovered planets. Our analysis procedure consisting of three steps: pre-processing of the data to remove discontinuities, gaps and outliers; ARMA-type model selection and fitting; and transit signal search of the residuals using a new Transit Comb Filter (TCF) that replaces traditional box-finding algorithms. We apply the procedures to simulated Kepler-like time series with known stellar and planetary signals to evaluate the effectiveness of the KARPS procedures. The ARMA-type modeling is effective at reducing stellar noise, but also reduces and transforms the transit signal into ingress/egress spikes. A periodogram based on the TCF is constructed to concentrate the signal of these periodic spikes. When a periodic transit is found, the model is displayed on a standard period-folded averaged light curve. We also illustrate the efficient coding in R.

  15. On Allometry Relations

    NASA Astrophysics Data System (ADS)

    West, Damien; West, Bruce J.

    2012-07-01

    There are a substantial number of empirical relations that began with the identification of a pattern in data; were shown to have a terse power-law description; were interpreted using existing theory; reached the level of "law" and given a name; only to be subsequently fade away when it proved impossible to connect the "law" with a larger body of theory and/or data. Various forms of allometry relations (ARs) have followed this path. The ARs in biology are nearly two hundred years old and those in ecology, geophysics, physiology and other areas of investigation are not that much younger. In general if X is a measure of the size of a complex host network and Y is a property of a complex subnetwork embedded within the host network a theoretical AR exists between the two when Y = aXb. We emphasize that the reductionistic models of AR interpret X and Y as dynamic variables, albeit the ARs themselves are explicitly time independent even though in some cases the parameter values change over time. On the other hand, the phenomenological models of AR are based on the statistical analysis of data and interpret X and Y as averages to yield the empirical AR: = ab. Modern explanations of AR begin with the application of fractal geometry and fractal statistics to scaling phenomena. The detailed application of fractal geometry to the explanation of theoretical ARs in living networks is slightly more than a decade old and although well received it has not been universally accepted. An alternate perspective is given by the empirical AR that is derived using linear regression analysis of fluctuating data sets. We emphasize that the theoretical and empirical ARs are not the same and review theories "explaining" AR from both the reductionist and statistical fractal perspectives. The probability calculus is used to systematically incorporate both views into a single modeling strategy. We conclude that the empirical AR is entailed by the scaling behavior of the probability density, which is derived using the probability calculus.

    We obtain the exact (confluent Heun) solutions to the massive scalar field in a gravity's rainbow Schwarzschild metric. With these solutions at hand, we study the Hawking radiation resulting from the tunneling rate through the event horizon. We show that the emission spectrum obeys nonextensive statistics and is halted when a certain mass remnant is reached. Next, we infer constraints on the rainbow parameters from recent LHC particle physics experiments and Hubble STIS astrophysics measurements. Finally, we study the low frequency limit in order to find the modified energy spectrum around the source.

    NASA Astrophysics Data System (ADS)

    Buchert, Thomas

    Variants of pancake models are considered which allow for the construction of a phenomenological link to the galaxy formation process. A control parameter space is introduced which defines different scenarios of galaxy formation. The sensibility of statistical measures of the small-scale structure with respect to this parameter freedom is demonstrated. This property of the galaxy formation model, together with the consequences of enlarging the box size of the simulation to a `fair sample scale', form the basis of arguments to support the possible revival of the standard `Hot-Dark-Matter' model.

    2017-06-01

    The TASEP is a paradigmatic model of out-of-equilibrium statistical physics, for which many quantities have been computed, either exactly or by approximate methods. In this work we study two new kinds of observables that have some relevance in biological or traffic models. They represent the probability for a given clearance zone of the lattice to be empty (for the first time) at a given time, starting from a step density profile. Exact expressions are obtained for single-time quantities, while more involved history-dependent observables are studied by Monte Carlo simulation, and partially predicted by a phenomenological approach.

    2007-06-01

    It has been proposed that certain Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Axis I disorders share overlapping clinical features, genetic contributions, and treatment response and fall within an "obsessive-compulsive" spectrum. Obsessive-compulsive personality disorder (OCPD) resembles obsessive-compulsive disorder (OCD) and other spectrum disorders in terms of phenomenology, comorbidity, neurocognition, and treatment response. This article critically examines the nosological profile of OCPD with special reference to OCD and related disorders. By viewing OCPD as a candidate member of the obsessive-compulsive spectrum, we gain a fresh approach to understanding its neurobiology, etiology, and potential treatments.

    Liebscher, Dierck-Ekkehard

    In order to get an estimation of the parameters of the cosmological model the statistics of narrow absorption lines in quasar spectra is evaluated. To this end a phenomenological model of the evolution of the corresponding absorbers in density, size, number and dimension is presented and compared with the observed evolution in the spectral density of the lines and their column density seen in the equivalent width. In spite of the wide range of possible models, the Einstein-deSitter model is shown to be unlikely because of the implied fast evolution in mass.

  1. The bodily experience of apraxia in everyday activities: a phenomenological study.

    PubMed

    Arntzen, Cathrine; Elstad, Ingunn

    2013-01-01

    The aim of this study is to explore apraxia as a phenomenon in everyday activities, as experienced by a group of stroke patients. Some consequences for clinical practice are suggested. In this phenomenological hermeneutical study, six persons with apraxia were followed from 2 to 6 months, from the early phase of stroke rehabilitation. ADL-situations and interactions with therapists were observed and videotaped repeatedly during the rehabilitation trajectory, to provide access to and familiarity with the participant's apractic difficulties over time. Two in-depth interviews were conducted with each participant. Interviews and video observations were analyzed together, taking Merleau-Ponty's concept of bodily intentionality as basis for analysis and his phenomenology as the main theoretical perspective of the study. Five types of altered bodily intentionality were described by the participants [ 1 ]: Gap between intention and bodily action [ 2 ], Fragmented awareness in action [ 3 ], Peculiar actions and odd bodies [ 4 ], Intentionality on the loose, and [ 5 ] Fighting against tools. These were recognized as characteristics typical of the apraxia experience. The phenomenology of Merleau-Ponty, and his concept of bodily intentionality in particular, elucidate the way specific apractic difficulties come into being and may thus render apraxia less incomprehensible. The apraxia phenomenon appears as characteristic fragmentations of anticipation inherent in action performance, thereby "slackening" the bodily intentionality. Identifying apractic changes of intentionality may help health professionals to adjust and individualize therapy, and facilitate patients' acting competence in everyday life.

  2. Children and adolescents living with atopic eczema: an interpretive phenomenological study with Chinese mothers.

    This article is a report on a phenomenological study of Chinese mothers' experiences of caring for their children who were living with atopic eczema. A mother's attitude and personality may have a direct influence on her child's adherence to treatment for atopic eczema. Thus, good communication between healthcare professionals and the mother is essential. Treatment and care should also be culturally appropriate. Using an interpretive phenomenological method, 14 interviews were conducted in Hong Kong, China from September 2007 to August 2008, with nine mothers caring for their children who were living with atopic eczema. Crist and Tanner's circular process of hermeneutic interpretive phenomenology was chosen to guide the data analysis. Mothers' coping patterns involved persistently dealing with enduring demands and seeking alternative therapies that were aimed at curing the disease. Four themes finally emerged from the data: (1) dealing with extra mothering, (2) giving up their life, (3) becoming an expert and (4) living with blame and worry. Mothers' coping patterns involved persistently finding ways to relieve their children's suffering with the aim of curing the disease and dealing with their own emotions related to the frustration resulting from giving up their life and living with blame and worry. The study findings provide nurses with an empathic insight into mothers' feelings and the enduring demands of caring for children with atopic eczema, and help nurses to develop culturally sensitive interventions, reinforce positive coping strategies, increase family function and improve health outcomes. © 2011 Blackwell Publishing Ltd.

  3. Does food addiction exist? A phenomenological discussion based on the psychiatric classification of substance-related disorders and addiction.

    The relationship between overeating, substance abuse and (behavioral) addiction is controversial. Medically established forms of addiction so far pertain to substance use disorders only. But the preliminary Diagnostic and Statistical Manual for Mental Disorders V (DSM V) suggests replacing the previous category 'Substance-Related Disorders' with 'Addiction and Related Disorders', thus for the first time allowing the diagnosis of behavioral addictions. In the past psychiatrists and psychologists have been reluctant to systematically delineate and classify the term behavioral addiction. However, there is a broad overlap between chemical and behavioral addiction including phenomenological, therapeutic, genetic, and neurobiological aspects. It is of interest to point out that the hormone leptin in itself has a pronounced effect on the reward system, thus suggesting an indirect link between overeating and 'chemical' addiction. Thus, leptin-deficient individuals could be classified as fulfilling criteria for food addiction. In our overview we first review psychological findings in chemical (substance-based) and subsequently in behavioral addiction to analyze the overlap. We discuss the diagnostic validity of food addiction, which in theory can be chemically and/or behaviorally based. Copyright © 2012 S. Karger GmbH, Freiburg.

  4. New mathematics for old physics: The case of lattice fluids

    NASA Astrophysics Data System (ADS)

    Barberousse, Anouk; Imbert, Cyrille

    2013-08-01

    We analyze the effects of the introduction of new mathematical tools on an old branch of physics by focusing on lattice fluids, which are cellular automata (CA)-based hydrodynamical models. We examine the nature of these discrete models, the type of novelty they bring about within scientific practice and the role they play in the field of fluid dynamics. We critically analyze Rohrlich's, Fox Keller's and Hughes' claims about CA-based models. We distinguish between different senses of the predicates "phenomenological" and "theoretical" for scientific models and argue that it is erroneous to conclude, as they do, that CA-based models are necessarily phenomenological in any sense of the term. We conversely claim that CA-based models of fluids, though at first sight blatantly misrepresenting fluids, are in fact conservative as far as the basic laws of statistical physics are concerned and not less theoretical than more traditional models in the field. Based on our case-study, we propose a general discussion of the prospect of CA for modeling in physics. We finally emphasize that lattice fluids are not just exotic oddities but do bring about new advantages in the investigation of fluids' behavior.

  5. On "being inspired" by Husserl's Phenomenology: reflections on Omery's exposition of phenomenology as a method of nursing research.

    1998-09-01

    The impact of Omery's article, "Phenomenology: A Method for Nursing Research," on nursing science is appraised. In particular, the influence of her emphasis on "being inspired" was compared with that of her detailed reviews of psychological phenomenologic methods. The author's experience of "being inspired" by Husserl's book, Ideas, is described. The author also discusses the tapping of this resource during three phases of her development as a researcher: (1) appraising methods derived from Husserl's phenomenology; (2) spelling out an approach, with help; and (3) "making clearer while glancing-toward." Omery's proposed linkage between philosophic inspiration and methodologic development is highlighted as a challenge to nurse researchers.

    It is hypothesized that the phenomenology of major depressive disorder (MDD) is subserved by disturbances in the structure and function of brain circuits; however, findings of structural abnormalities using MRI have been inconsistent. Generalized q-sampling imaging (GQI) methodology provides an opportunity to assess the functional integrity of white matter tracts in implicated circuits. The study population was comprised of 16 outpatients with MDD (mean age 44.81±2.2 years) and 30 age- and gender-matched healthy controls (mean age 45.03±1.88 years). We excluded participants with any other primary mental disorder, substance use disorder, or any neurological illnesses. We used T1-weighted 3D MRI with voxel-based morphometry (VBM) and vertex-wise shape analysis, and GQI with voxel-based statistical analysis (VBA), graph theoretical analysis (GTA) and network-based statistical (NBS) analysis to evaluate brain structure and connectivity abnormalities in MDD compared to healthy controls correlates with clinical measures of depressive symptom severity, Hamilton Depression Rating Scale 17-item (HAMD) and Hospital Anxiety and Depression Scale (HADS). Using VBM and vertex-wise shape analyses, we found significant volumetric decreases in the hippocampus and amygdala among subjects with MDD (p<0.001). Using GQI, we found decreases in diffusion anisotropy in the superior longitudinal fasciculus and increases in diffusion probability distribution in the frontal lobe among subjects with MDD (p<0.01). In GTA and NBS analyses, we found several disruptions in connectivity among subjects with MDD, particularly in the frontal lobes (p<0.05). In addition, structural alterations were correlated with depressive symptom severity (p<0.01). Small sample size; the cross-sectional design did not allow us to observe treatment effects in the MDD participants. Our results provide further evidence indicating that MDD may be conceptualized as a brain disorder with abnormal circuit structure and connectivity. Copyright © 2016 Elsevier B.V.

    Ostfeld, Richard S.; Brunner, Jesse L.

    2015-01-01

    The evidence that climate warming is changing the distribution of Ixodes ticks and the pathogens they transmit is reviewed and evaluated. The primary approaches are either phenomenological, which typically assume that climate alone limits current and future distributions, or mechanistic, asking which tick-demographic parameters are affected by specific abiotic conditions. Both approaches have promise but are severely limited when applied separately. For instance, phenomenological approaches (e.g. climate envelope models) often select abiotic variables arbitrarily and produce results that can be hard to interpret biologically. On the other hand, although laboratory studies demonstrate strict temperature and humidity thresholds for tick survival, these limits rarely apply to field situations. Similarly, no studies address the influence of abiotic conditions on more than a few life stages, transitions or demographic processes, preventing comprehensive assessments. Nevertheless, despite their divergent approaches, both mechanistic and phenomenological models suggest dramatic range expansions of Ixodes ticks and tick-borne disease as the climate warms. The predicted distributions, however, vary strongly with the models' assumptions, which are rarely tested against reasonable alternatives. These inconsistencies, limited data about key tick-demographic and climatic processes and only limited incorporation of non-climatic processes have weakened the application of this rich area of research to public health policy or actions. We urge further investigation of the influence of climate on vertebrate hosts and tick-borne pathogen dynamics. In addition, testing model assumptions and mechanisms in a range of natural contexts and comparing their relative importance as competing models in a rigorous statistical framework will significantly advance our understanding of how climate change will alter the distribution, dynamics and risk of tick-borne disease.

    There is a great overlap between the way of seeing the world in clinical homeopathy and in the technical philosophical system known as phenomenology. A knowledge of phenomenologic principles reveals Hahnemann to have been an unwitting phenomenologist. The ideas of phenomenology as applied to medicine show that homeopathy is the ideal medical system to fulfill the goals of coming ever closer to true patient concerns and experience of illness.

    2013-01-01

    One of the leading cognitive models of auditory verbal hallucinations (AVHs) proposes such experiences result from a disturbance in the process by which inner speech is attributed to the self. Research in this area has, however, proceeded in the absence of thorough cognitive and phenomenological investigations of the nature of inner speech, against which AVHs are implicitly or explicitly defined. In this paper we begin by introducing philosophical phenomenology and highlighting its relevance to AVHs, before briefly examining the evolving literature on the relation between inner experiences and AVHs. We then argue for the need for philosophical phenomenology (Phenomenology) and the traditional empirical methods of psychology for studying inner experience (phenomenology) to mutually inform each other to provide a richer and more nuanced picture of both inner experience and AVHs than either could on its own. A critical examination is undertaken of the leading model of AVHs derived from phenomenological philosophy, the ipseity disturbance model. From this we suggest issues that future work in this vein will need to consider, and examine how interdisciplinary methodologies may contribute to advances in our understanding of AVHs. Detailed suggestions are made for the direction and methodology of future work into AVHs, which we suggest should be undertaken in a context where phenomenology and physiology are both necessary, but neither sufficient.

  11. Scale-dependent cyclone-anticyclone asymmetry in a forced rotating turbulence experiment

    NASA Astrophysics Data System (ADS)

    2014-03-01

    We characterize the statistical and geometrical properties of the cyclone-anticyclone asymmetry in a statistically steady forced rotating turbulence experiment. Turbulence is generated by a set of vertical flaps which continuously inject velocity fluctuations towards the center of a tank mounted on a rotating platform. We first characterize the cyclone-anticyclone asymmetry from conventional single-point vorticity statistics. We propose a phenomenological model to explain the emergence of the asymmetry in the experiment, from which we predict scaling laws for the root-mean-square velocity in good agreement with the experimental data. We further quantify the cyclone-anticyclone asymmetry using a set of third-order two-point velocity correlations. We focus on the correlations which are nonzero only if the cyclone-anticyclone symmetry is broken. They offer two advantages over single-point vorticity statistics: first, they are defined from velocity measurements only, so an accurate resolution of the Kolmogorov scale is not required; second, they provide information on the scale-dependence of the cyclone-anticyclone asymmetry. We compute these correlation functions analytically for a random distribution of independent identical vortices. These model correlations describe well the experimental ones, indicating that the cyclone-anticyclone asymmetry is dominated by the large-scale long-lived cyclones.

  12. Harnessing psychoanalytical methods for a phenomenological neuroscience

    PubMed Central

    Cusumano, Emma P.; Raz, Amir

    2014-01-01

    Psychoanalysis proffers a wealth of phenomenological tools to advance the study of consciousness. Techniques for elucidating the structures of subjective life are sorely lacking in the cognitive sciences; as such, experiential reporting techniques must rise to meet both complex theories of brain function and increasingly sophisticated neuroimaging technologies. Analysis may offer valuable methods for bridging the gap between first-person and third-person accounts of the mind. Using both systematic observational approaches alongside unstructured narrative interactions, psychoanalysts help patients articulate their experience and bring unconscious mental contents into awareness. Similar to seasoned meditators or phenomenologists, individuals who have undergone analysis are experts in discerning and describing their subjective experience, thus making them ideal candidates for neurophenomenology. Moreover, analytic techniques may provide a means of guiding untrained experimental participants to greater awareness of their mental continuum, as well as gathering subjective reports about fundamental yet elusive aspects of experience including selfhood, temporality, and inter-subjectivity. Mining psychoanalysis for its methodological innovations provides a fresh turn for the neuropsychoanalysis movement and cognitive science as a whole – showcasing the integrity of analysis alongside the irreducibility of human experience.

    ABSTRACT Over recent years there has been a growing interest in identifying the early stages of psychosis. The At Risk Mental State (ARMS) is characteristic of the prodromal stages of psychosis and its identification gives rise to a number of clinical and research opportunities including early intervention and prevention of psychosis. This study employs interpretative phenomenological analysis to gain insights into the subjective experience and individuals understanding of the development of their ARMS. Five participants took part and provided information on the experience of symptoms, life prior to onset of their ARMS and their understanding of symptoms and their development through a semi structured interview. From the analysis of transcripts eight themes emerged which were common across participants accounts. Three themes of experience (disturbed world/disturbed self, disconnection with the world, thunderstruck) and five themes of understanding (absence of understanding, use of others, identity, forming links, fragmented understanding) were identified. Themes are explored in detail and discussed in relation to existing literature and theory. Clinical implications, directions for future research, and limitations are discussed within. PMID:28689474

    We present a new environment for computations in particle physics phenomenology employing recent developments in cloud computing. On this environment users can create and manage "virtual" machines on which the phenomenology codes/tools can be deployed easily in an automated way. We analyze the performance of this environment based on "virtual" machines versus the utilization of physical hardware. In this way we provide a qualitative result for the influence of the host operating system on the performance of a representative set of applications for phenomenology calculations.

    This paper describes the important role of our deep immersions in philosophy in the development of our phenomenological-contextualist approach to psychoanalysis. Influenced most particularly by the phenomenological movement, our collaborative dialogue over more than four decades has led us to a shared commitment to reflection upon the philosophical underpinnings and constitutive contexts of origin of all our theoretical ideas. The growth of our thinking follows an endlessly recurring phenomenological circle joining theoretical perspectives with the inquirers from whose emotional worlds they arise.

    Multiculturalism is defined as the combination, within a given territory, of a social unit and a cultural plurality by way of exchanges and communications among actors who use different categories of expression, analysis and interpretation. A multiculturalist project should not promote a society that is split up into closed groups; on the contrary, it should set forth policies based on communication and cooperation processes among the cultural communities. To understand this concept, we will present the ontological basis of this phenomenonin the search for a communicational solution, with our startpoint being a phenomenological description of the way in which multiculturalism manifests to us in life; to later deepen into the meaning of the phenomenon,and finally offer a pluralist solution to the problems and challenges cultural differences bring about.

    The evidence of experience of intuitive knowing in the clinical setting has to this point only been informal and anecdotal. Reported experiences thus need to be either validated or refuted so that its place in emergency nursing can be determined. The history, nature and component themes captured within the intuitive practice of emergency nursing are described. This study was informed by the philosophy and method of phenomenology. Participants were 14 experienced emergency nurses. Through their narrative accounts and recall of events their experience of knowing was captured. Through a Van Manen process and a Gadamerian analysis, six themes associated with the ways in which the participants experienced intuition in clinical practice, were identified. This paper reveals the six emerging themes as knowledge, experience, connection, feeling, syncretism and trust.

    Dreams are a most remarkable experiment in psychology and neuroscience, conducted every night in every sleeping person. They show that our brain, disconnected from the environment, can generate by itself an entire world of conscious experiences. Content analysis and developmental studies have furthered our understanding of dream phenomenology. In parallel, brain lesion studies, functional imaging, and neurophysiology have advanced our knowledge of the neural basis of dreaming. It is now possible to start integrating these two strands of research in order to address some fundamental questions that dreams pose for cognitive neuroscience: how conscious experiences in sleep relate to underlying brain activity; why the dreamer is largely disconnected from the environment; and whether dreaming is more closely related to mental imagery or to perception.

We show that the Urbach energy is not related to topological disorder but to the Gaussian width (σπ) of the πDOS, peaked at ±Eπ energies above/below the Fermi level. σπ, on its turn, is not related in a straightforward manner to the disorder. The disorder is better represented by the σπ/Eπ ratio, expressing the disorder-induced narrowing of the Tauc optical gap.

    The principal aim of this study was to examine the impact of variability in interpersonal coordination and individual organization on rowing performance. The second aim was to analyze crew phenomenology in order to understand how rowers experience their joint actions when coping with constraints emerging from the race. We conducted a descriptive and exploratory study of two coxless pair crews during a 3000-m rowing race against the clock. As the investigation was performed in an ecological context, we postulated that our understanding of the behavioral dynamics of interpersonal coordination and individual organization and the variability in performance would be enriched through the analysis of crew phenomenology. The behavioral dynamics of individual organization were assessed at kinematic and kinetic levels, and interpersonal coordination was examined by computing the relative phase between oar angles and oar forces and the difference in the oar force impulse of the two rowers. The inter-cycle variability of the behavioral dynamics of one international and one national crew was evaluated by computing the root mean square and the Cauchy index. Inter-cycle variability was considered significantly high when the behavioral and performance data for each cycle were outside of the confidence interval. Crew phenomenology was characterized on the basis of self-confrontation interviews and the rowers' concerns were then analyzed according to course-of-action methodology to identify the shared experiences. Our findings showed that greater behavioral variability could be either “perturbing” or “functional” depending on its impact on performance (boat velocity); the rowers experienced it as sometimes meaningful and sometimes meaningless; and their experiences were similar or diverging. By combining phenomenological and behavioral data, we explain how constraints not manipulated by an experimenter but emerging from the ecological context of a race can be associated with functional adaptations or perturbations of the interpersonal coordination.

    Background As an inherently human process fraught with subjectivity, dynamic interaction, and change, social interaction knowledge translation (KT) invites implementation scientists to explore what might be learned from adopting the academic tradition of social constructivism and an interpretive research approach. This paper presents phenomenological investigation of the second cycle of a participatory action KT intervention in the home care sector to answer the question: What is the nature of the process of implementing KT through social interaction? Methods Social phenomenology was selected to capture how the social processes of the KT intervention were experienced, with the aim of representing these as typical socially-constituted patterns. Participants (n = 203), including service providers, case managers, administrators, and researchers organized into nine geographically-determined multi-disciplinary action groups, purposefully selected and audiotaped three meetings per group to capture their enactment of the KT process at early, middle, and end-of-cycle timeframes. Data, comprised of 36 hours of transcribed audiotapes augmented by researchers' field notes, were analyzed using social phenomenology strategies and authenticated through member checking and peer review. Results Four patterns of social interaction representing organization, team, and individual interests were identified: overcoming barriers and optimizing facilitators; integrating 'science push' and 'demand pull' approaches within the social interaction process; synthesizing the research evidence with tacit professional craft and experiential knowledge; and integrating knowledge creation, transfer, and uptake throughout everyday work. Achieved through relational transformative leadership constituted simultaneously by both structure and agency, in keeping with social phenomenology analysis approaches, these four patterns are represented holistically in a typical construction, specifically, a participatory action KT (PAKT) model. Conclusion Study findings suggest the relevance of principles and foci from the field of process evaluation related to intervention implementation, further illuminating KT as a structuration process facilitated by evolving transformative leadership in an active and integrated context. The model provides guidance for proactively constructing a 'fit' between content, context, and facilitation in the translation of evidence informing professional craft knowledge. PMID:19442294

    The statistical model in combination with the detailed balance principle is able to phenomenologically calculate and analyze spin- and flavor-dependent properties like magnetic moments (with effective masses, with effective charge, or with both effective mass and effective charge), quark spin polarization and distribution, the strangeness suppression factor, and \\overline{d}-\\overline{u} asymmetry incorporating the strange sea. The s\\overline{s} in the sea is said to be generated via the basic quark mechanism but suppressed by the strange quark mass factor ms>m_{u,d}. The magnetic moments of the octet baryons are analyzed within the statistical model, by putting emphasis on the SU(3) symmetry-breaking effects generated by the mass difference between the strange and non-strange quarks. The work presented here assumes hadrons with a sea having an admixture of quark gluon Fock states. The results obtained have been compared with theoretical models and experimental data.

    We have applied the Hauser-Feshbach statistical theory, in a Monte-Carlo implementation, to the de-excitation of fission fragments, obtaining a reasonable description of the characteristics of neutrons and gamma rays emitted before beta decays toward stability. Originally implemented for the spontaneous fission of 252Cf and the neutroninduced fission of 235U and 239Pu at thermal neutron energy, in this contribution we discuss the extension of the formalism to incident neutron energies up to 20 MeV. For the emission of pre-fission neutrons, at incident energies beyond second-chance fission, we take into account both the pre-equilibrium and statistical pre-fission components. Phenomenological parameterizations of mass, charge and TKE yields are used to obtain the initial conditions for the fission fragments that subsequently decay via neutron and emissions. We illustrate this approach for 239Pu(n,f).

  5. The politics of phenomenological concepts in nursing.

    PubMed

    Holmes, C A

    1996-09-01

    This paper challenges those nurses who champion Heideggerian phenomenology, by outlining some of the possible political consequences of that philosophy. Some relationships between phenomenology and fascism are discussed, with special reference to anti-humanism and authenticity. Heidegger's commitment to Nazism is affirmed and, following the lead of other recent contributions to the debate, it is suggested that this was the likely, if not inevitable, result of his phenomenological philosophy. It is concluded that, because of its immanent fascism, Heideggerian phenomenology is at odds with the general value orientation publicly espoused by the nursing profession, and that this may render it not only unsuitable as a means of understanding and elaborating nursing knowledge, but also actively counter-productive to the conventional aspirations of nurses.

    The shipping industry has historically leaned towards a biomedical model of health when assessing, treating and caring for seafarers. In recent years there has been more concern for the mental health of seafarers in both the academic literature and the commercial world, however, the psychological and emotional well-being of seafarers still largely falls on the shoulders of the port chaplains. The aim of the study was to explore how port chaplains make sense of providing welfare for seafarers by taking an idiographic, phenomenological approach (IPA). Six male participants working as chaplains in United Kingdom ports took part in recorded face-to-face, semi-structured interviews covering three areas of questioning: role, identity and coping. Interviews were transcribed verbatim, and data analysed using interpretative phenomenological analysis. Three super-ordinate themes were identified from participants accounts; "We walk a very strange and middle path", "Exploited" and "Patching up". Rich data emerged in relation to the personal impact chaplains felt they made, which was facilitated by the historical role of the Church; this led to the second super-ordinate theme of how chaplains felt towards seafarers. Lastly, the analysis demonstrates how chaplains adapt to the limitations forced upon them to provide welfare, and a degree of acceptance at the injustice. Results were discussed in reference to theoretical models, including self-efficacy, empathic responding and the transactional model of stress and coping. Chaplains in ports perform their role autonomously with no input from healthcare professionals. Recommendations are made for a biopsychosocial model of health involving primary care, benefiting the health and well-being of seafarers and providing support and guidance for port chaplains at the frontline of welfare for seafarers.

    Mutations in granulin (PGRN) and tau (MAPT), and hexanucleotide repeat expansions near the C9orf72 genes are the most prevalent genetic causes of frontotemporal lobar degeneration. Although behavior, language and movement presentations are common, the relationship between genetic subgroup and movement disorder phenomenology is unclear. We conducted a systematic review and meta-analysis of the literature characterizing the spectrum and prevalence of movement disorders in genetic frontotemporal lobar degeneration. Electronic databases were searched using terms related to frontotemporal lobar degeneration and movement disorders. Articles were included when cases had a proven genetic cause. Study-specific prevalence estimates for clinical features were transformed using Freeman-Tukey arcsine transformation, allowing for pooled estimates of prevalence to be generated using random-effects models. The mean age at onset was earlier in those with MAPT mutations compared to PGRN (p<0.001) and C9orf72 (p = 0.024). 66.5% of subjects had an initial non-movement presentation that was most likely a behavioral syndrome (35.7%). At any point during the disease, parkinsonism was the most common movement syndrome reported in 79.8% followed by progressive supranuclear palsy (PSPS) and corticobasal (CBS) syndromes in 12.2% and 10.7%, respectively. The prevalence of movement disorder as initial presentation was higher in MAPT subjects (35.8%) compared to PGRN subjects (10.1). In those with a non-movement presentation, language disorder was more common in PGRN subjects (18.7%) compared to MAPT subjects (5.4%). This represents the first systematic review and meta-analysis of the occurrence of movement disorder phenomenology in genetic frontotemporal lobar degeneration. Standardized prospective collection of clinical information in conjunction with genetic characterization will be crucial for accurate clinico-genetic correlation.

    Background Mutations in granulin (PGRN) and tau (MAPT), and hexanucleotide repeat expansions near the C9orf72 genes are the most prevalent genetic causes of frontotemporal lobar degeneration. Although behavior, language and movement presentations are common, the relationship between genetic subgroup and movement disorder phenomenology is unclear. Objective We conducted a systematic review and meta-analysis of the literature characterizing the spectrum and prevalence of movement disorders in genetic frontotemporal lobar degeneration. Methods Electronic databases were searched using terms related to frontotemporal lobar degeneration and movement disorders. Articles were included when cases had a proven genetic cause. Study-specific prevalence estimates for clinical features were transformed using Freeman-Tukey arcsine transformation, allowing for pooled estimates of prevalence to be generated using random-effects models. Results The mean age at onset was earlier in those with MAPT mutations compared to PGRN (p<0.001) and C9orf72 (p = 0.024). 66.5% of subjects had an initial non-movement presentation that was most likely a behavioral syndrome (35.7%). At any point during the disease, parkinsonism was the most common movement syndrome reported in 79.8% followed by progressive supranuclear palsy (PSPS) and corticobasal (CBS) syndromes in 12.2% and 10.7%, respectively. The prevalence of movement disorder as initial presentation was higher in MAPT subjects (35.8%) compared to PGRN subjects (10.1). In those with a non-movement presentation, language disorder was more common in PGRN subjects (18.7%) compared to MAPT subjects (5.4%). Summary This represents the first systematic review and meta-analysis of the occurrence of movement disorder phenomenology in genetic frontotemporal lobar degeneration. Standardized prospective collection of clinical information in conjunction with genetic characterization will be crucial for accurate clinico-genetic correlation. PMID:27100392

  9. Conceptual Change in Understanding the Nature of Science Learning: An Interpretive Phenomenological Analysis

    NASA Astrophysics Data System (ADS)

    DiBenedetto, Christina M.

    This study is the first of its kind to explore the thoughts, beliefs, attitudes and values of secondary educators as they experience conceptual change in their understanding of the nature of science learning vis a vis the Framework for K-12 Science Education published by the National Research Council. The study takes aim at the existing gap between the vision for science learning as an active process of inquiry and current pedagogical practices in K-12 science classrooms. For students to understand and explain everyday science ideas and succeed in science studies and careers, the means by which they learn science must change. Focusing on this change, the study explores the significance of educator attitudes, beliefs and values to science learning through interpretive phenomenological analysis around the central question, "In what ways do educators understand and articulate attitudes and beliefs toward the nature of science learning?" The study further explores the questions, "How do educators experience changes in their understanding of the nature of science learning?" and "How do educators believe these changes influence their pedagogical practice?" Study findings converge on four conceptions that science learning: is the action of inquiry; is a visible process initiated by both teacher and learner; values student voice and changing conceptions is science learning. These findings have implications for the primacy of educator beliefs, attitudes and values in reform efforts, science teacher leadership and the explicit instruction of both Nature of Science and conceptual change in educator preparation programs. This study supports the understanding that the nature of science learning is cognitive and affective conceptual change. Keywords: conceptual change, educator attitudes and beliefs, framework for K-12 science education, interpretive phenomenological analysis, nature of science learning, next generation science standards, science professional development, secondary science education.

    Research has found relational qualities of power and intimacy to exist within hearer-voice interactions. The present study aimed to provide a deeper understanding of the interpersonal context of voice hearing by exploring participants' relationships with their voices and other people in their lives. This research was designed in consultation with service users and employed a qualitative, phenomenological, and idiographic design using semi-structured interviews. Ten participants, recruited via mental health services, and who reported hearing voices in the previous week, completed the interviews. These were transcribed verbatim and analysed using interpretative phenomenological analysis. Five themes resulted from the analysis. Theme 1: 'person and voice' demonstrated that participants' voices often reflected the identity, but not always the quality of social acquaintances. Theme 2: 'voices changing and confirming relationship with the self' explored the impact of voice hearing in producing an inferior sense-of-self in comparison to others. Theme 3: 'a battle for control' centred on issues of control and a dilemma of independence within voice relationships. Theme 4: 'friendships facilitating the ability to cope' and theme 5: 'voices creating distance in social relationships' explored experiences of social relationships within the context of voice hearing, and highlighted the impact of social isolation for voice hearers. The study demonstrated the potential role of qualitative research in developing theories of voice hearing. It extended previous research by highlighting the interface between voices and the social world of the hearer, including reciprocal influences of social relationships on voices and coping. Improving voice hearers' sense-of-self may be a key factor in reducing the distress caused by voices. ©2010 The British Psychological Society.

  11. Model-independent fit to Planck and BICEP2 data

    Inflation is the leading theory to describe elegantly the initial conditions that led to structure formation in our Universe. In this paper, we present a novel phenomenological fit to the Planck, WMAP polarization (WP) and the BICEP2 data sets using an alternative parametrization. Instead of starting from inflationary potentials and computing the inflationary observables, we use a phenomenological parametrization due to Mukhanov, describing inflation by an effective equation of state, in terms of the number of e-folds and two phenomenological parameters α and β. Within such a parametrization, which captures the different inflationary models in a model-independent way, the values of the scalar spectral index ns, its running and the tensor-to-scalar ratio r are predicted, given a set of parameters (α ,β). We perform a Markov Chain Monte Carlo analysis of these parameters, and we show that the combined analysis of Planck and WP data favors the Starobinsky and Higgs inflation scenarios. Assuming that the BICEP2 signal is not entirely due to foregrounds, the addition of this last data set prefers instead the ϕ2 chaotic models. The constraint we get from Planck and WP data alone on the derived tensor-to-scalar ratio is r <0.18 at 95% C.L., value which is consistent with the one quoted from the BICEP2 Collaboration analysis, r =0.16-0.05+0-06, after foreground subtraction. This is not necessarily at odds with the 2σ tension found between Planck and BICEP2 measurements when analyzing data in terms of the usual ns and r parameters, given that the parametrization used here, for the preferred value ns≃0.96, allows only for a restricted parameter space in the usual (ns,r) plane.

    We systematically measured the differential cross sections of inelastic α scattering off self-conjugate A =4 n nuclei at two incident energies Eα=130 MeV and 386 MeV at Research Center for Nuclear Physics, Osaka University. The measured cross sections were analyzed by the distorted-wave Born-approximation (DWBA) calculation using the single-folding potentials, which are obtained by folding macroscopic transition densities with the phenomenological α N interaction. The DWBA calculation with the density-dependent α N interaction systematically overestimates the cross sections for the Δ L =0 transitions. However, the DWBA calculation using the density-independent α N interaction reasonably well describes all the transitions with Δ L =0 -4. We examined uncertainties in the present DWBA calculation stemming from the macroscopic transition densities, distorting potentials, phenomenological α N interaction, and coupled channel effects in 12C. It was found that the DWBA calculation is not sensitive to details of the transition densities nor the distorting potentials, and the phenomenological density-independent α N interaction gives reasonable results. The coupled-channel effects are negligibly small for the 21+ and 31- states in 12C, but not for the 02+ state. However, the DWBA calculation using the density-independent interaction at Eα=386 MeV is still reasonable even for the 02+ state. We concluded that the macroscopic DWBA calculations using the density-independent interaction are reliably applicable to the analysis of inelastic α scattering at Eα˜100 MeV /u .

  14. The transitional behaviour of avalanches in cohesive granular materials

    NASA Astrophysics Data System (ADS)

    Quintanilla, M. A. S.; Valverde, J. M.; Castellanos, A.

    2006-07-01

    We present a statistical analysis of avalanches of granular materials that partially fill a slowly rotated horizontal drum. For large sized noncohesive grains the classical coherent oscillation is reproduced, consisting of a quasi-periodic succession of regularly sized avalanches. As the powder cohesiveness is increased by decreasing the particle size, we observe a gradual crossover to a complex dynamics that resembles the transitional behaviour observed in fusion plasmas. For particle size below ~50 µm, avalanches lose a characteristic size, retain a short term memory and turn gradually decorrelated in the long term as described by a Markov process. In contrast, large grains made cohesive by coating them with adhesive microparticles display a distinct phenomenology, characterized by a quasi-regular succession of well defined small precursors and large relaxation events. The transition from a one-peaked distribution (noncohesive large beads) to a flattened distribution (fine cohesive beads) passing through the two-peaked distribution of cohesive large beads had already been predicted using a coupled-map lattice model, as the relaxation mechanism of grain reorganization becomes dominant to the detriment of inertia.

  15. Gamma-Ray Emission in Dissipative Pulsar Magnetospheres: from Theory to Fermi Observations

    2014-01-01

    We compute the patterns of gamma-ray emission due to curvature radiation in dissipative pulsar magnetospheres. Our ultimate goal is to construct macrophysical models that are able to reproduce the observed gamma-ray light curve phenomenology recently published in the Second Fermi Pulsar Catalog. We apply specific forms of Ohm's law on the open field lines using a broad range for the macroscopic conductivity values that result in solutions ranging, from near-vacuum to near-force-free. Using these solutions, we generate model gamma-ray light curves by calculating realistic trajectories and Lorentz factors of radiating particles under the influence of both the accelerating electric fields and curvature radiation reaction. We further constrain our models using the observed dependence of the phase lags between the radio and gamma-ray emission on the gamma-ray peak separation. We perform a statistical comparison of our model radio-lag versus peak-separation diagram and the one obtained for the Fermi standard pulsars. We find that for models of uniform conductivity over the entire open magnetic field line region, agreement with observations favors higher values of this parameter. We find, however, significant improvement in fitting the data with models that employ a hybrid form of conductivity, specifically, infinite conductivity interior to the light cylinder and high but finite conductivity on the outside. In these models the gamma-ray emission is produced in regions near the equatorial current sheet but modulated by the local physical properties. These models have radio lags near the observed values and statistically best reproduce the observed light curve phenomenology. Additionally, they also produce GeV photon cut-off energies.

    The aim of this study was to describe the phenomenology of mania and depression in bipolar patients experiencing a manic episode with mixed features as defined in the new Diagnostic and Statistical Manual of Mental Disorders (DSM-5). In this multicenter, international on-line survey (the IMPACT study), 700 participants completed a 54-item questionnaire on demographics, diagnosis, symptomatology, communication of the disease, impact on life, and treatment received. Patients with a manic episode with or without DSM-5 criteria for mixed features were compared using descriptive and inferential statistics. Patients with more than 3 depressive symptoms were more likely to have had a delay in diagnosis, more likely to have experienced shorter symptom-free periods, and were characterized by a marked lower prevalence of typical manic manifestations. All questionnaire items exploring depressive symptomatology, including the DSM-5 criteria defining a manic episode as "with mixed features", were significantly overrepresented in the group of patients with depressive symptoms. Anxiety associated with irritability/agitation was also more frequent among patients with mixed features. Retrospective cross-sectional design, sensitive to recall bias. Two of the 6 DSM-5 required criteria for the specifier "with mixed features" were not explored: suicidality and psychomotor retardation. Bipolar disorder patients with at least 3 depressive symptoms during a manic episode self-reported typical symptomatology. Anxiety with irritability/agitation differentiated patients with depressive symptoms during mania from those with "pure" manic episodes. The results support the use of DSM-5 mixed features specifier and its value in research and clinical practice. Copyright © 2014 Elsevier B.V. All rights reserved.

    2012-12-01

    To present background, principles, and procedures for a strategy for qualitative analysis called systematic text condensation and discuss this approach compared with related strategies. Giorgi's psychological phenomenological analysis is the point of departure and inspiration for systematic text condensation. The basic elements of Giorgi's method and the elaboration of these in systematic text condensation are presented, followed by a detailed description of procedures for analysis according to systematic text condensation. Finally, similarities and differences compared with other frequently applied methods for qualitative analysis are identified, as the foundation of a discussion of strengths and limitations of systematic text condensation. Systematic text condensation is a descriptive and explorative method for thematic cross-case analysis of different types of qualitative data, such as interview studies, observational studies, and analysis of written texts. The method represents a pragmatic approach, although inspired by phenomenological ideas, and various theoretical frameworks can be applied. The procedure consists of the following steps: 1) total impression - from chaos to themes; 2) identifying and sorting meaning units - from themes to codes; 3) condensation - from code to meaning; 4) synthesizing - from condensation to descriptions and concepts. Similarities and differences comparing systematic text condensation with other frequently applied qualitative methods regarding thematic analysis, theoretical methodological framework, analysis procedures, and taxonomy are discussed. Systematic text condensation is a strategy for analysis developed from traditions shared by most of the methods for analysis of qualitative data. The method offers the novice researcher a process of intersubjectivity, reflexivity, and feasibility, while maintaining a responsible level of methodological rigour.

    2016-06-01

    This study aimed to explore the construct of recovery from anorexia nervosa through the medium of weblogs, focusing on the benefits and barriers to the recovery process. Data were extracted from female ( n = 7) and male ( n = 1) participants' textual pro-recovery weblogs, all of which were posted between 2013 and 2015 in the public domain. Data were analysed using interpretative phenomenological analysis. Three superordinate themes were identified: (1) barriers to recovery, (2) factors increasing the likelihood of recovery and (3) support. Results suggest supportive relationships, regaining control and recognising the consequences of the eating disorder benefit recovery, whereas public perceptions, the anorexia nervosa voice and time act as barriers to recovery. Out of eight participants, four described seeking professional help as part of their recovery, of which three believed their professional therapy experience helped aid recovery. Implications for anorexia nervosa treatment are discussed in detail.

    The prevalence of older adult female gambling participation and gambling disorder is increasing in the UK, and there is a paucity of published research available to understand possible risk factors for frequent gambling in this demographic. The aim of the current study was to identify and explore motivations and patterns of gambling behavior in high-frequency older adult female gamblers in the UK, from the perspective of the individual and in the context of their experience of aging. Ten UK older adult female high-frequency gamblers were recruited via stratified purposive sampling, with a mean age of 70.4 years. Data was collected via semistructured interviews and analyzed using interpretative phenomenological analysis. Three core themes representative of the experience of this phenomenon emerged from the transcripts, including: Filling voids, emotional escape, and overspending. The present study has provided a contextualized understanding of motivating factors and several age-related vulnerabilities that may account for high gambling frequency in this population.

    This study explores the lived experience of being a Speech-Language Therapist (S-L Therapist) in the South African Western Cape public health service. The lived experience of seven S-L Therapists with varied clinical experience was illuminated using a qualitative phenomenological research design. S-L Therapists, working in the three Western Cape tertiary hospitals, provided an in-depth account of their experiences as S-L Therapists. The audio recorded interviews were transcribed verbatim and analysed using an adaptation of Colaizzi's (1978) method of analysis. The rigour and trustworthiness of the research process was informed by consideration of issues of credibility, applicability, confirmability and dependability as they relate to phenomenological design. Five main themes emerged from data analysis: expectations of practice and practice realities; being part of the "underdog" profession: role definition and status; being connected; the holistic nature of the S-L Therapist's practice; and erosion or promotion.The implications for training and support of S-L Therapists by managers and policymakers and peers are highlighted.

  6. Self-similarity in nature

    2000-02-01

    A general phenomenological approach to the analysis of experimental temporal, spatial and energetic series for extracting truly physical non-model parameters ("passport data") is presented, which may be used to characterize and distinguish the evolution as well as the spatial and energetic structure of any open nonlinear dissipative system. This methodology is based on a postulate concerning the crucial information contained in the sequences of non-regularities of the measured dynamic variable (temporal, spatial, energetic). In accordance with this approach, multi-parametric formulas for dynamic variable power spectra as well as for structural functions of different orders are identical for every spatial-temporal-energetic level of the system under consideration. In effect, this entails the introduction of a new kind of self-similarity in Nature. An algorithm has been developed for obtaining as many "passport data" as are necessary for the characterization of a dynamic system. Applications of this approach in the analysis of various experimental series (temporal, spatial, energetic) demonstrate its potential for defining adequate phenomenological parameters of different dynamic processes and structures.

    2014-03-01

    In this study, constitutive equations for superplastic materials with an extra large elongation were investigated through mechanical analysis. From the view of phenomenology, firstly, some traditional empirical constitutive relations were standardized by restricting some strain paths and parameter conditions, and the coefficients in these relations were strictly given new mechanical definitions. Subsequently, a new, general constitutive equation with varying parameters was theoretically deduced based on the general mechanical equation of state. The superplastic tension test data of Zn-5%Al alloy at 340 °C under strain rates, velocities, and loads were employed for building a new constitutive equation and examining its validity. Analysis results indicated that the constitutive equation with varying parameters could characterize superplastic flow behavior in practical superplastic forming with high prediction accuracy and without any restriction of strain path or deformation condition, showing good industrial or scientific interest. On the contrary, those empirical equations have low prediction capabilities due to constant parameters and poor applicability because of the limit of special strain path or parameter conditions based on strict phenomenology.

    Near-death experiences (NDEs) refer to profound psychological events that can have an important impact on the experiencers' (NDErs) lives. Previous studies have shown that NDEs memories are phenomenologically rich. In the present study, we therefore aimed to extract the common themes (referred to as "features" in the NDE literature) reported by NDErs by analyzing all the concepts stored in the narratives of their experiences. A qualitative thematic analysis has been carried out on 34 cardiac arrest survivors' NDE narratives. Our results shed the light on the structure of the narratives by identifying 10 "time-bounded" themes which refer to isolated events encountered during the NDE and 1 "transversal" theme which characterizes the whole narrative and generally appears as a retrospective comment of self-reflection on the experience. The division of narratives into themes provides us with detailed information about the vocabulary used by NDErs to describe their experience. This established thematic method enables a rigorous description of the phenomenon, ensuring the inclusion of all self-reported manifestations of themes in narratives.

    2018-01-01

    Understand the impact of critical-illness news on the experience of family members at an Intensive Care Unit. Phenomenological approach according to Van Manen's method. Open interviews were held with 21 family members. From analysis and interpretation of the data, three essential themes were identified: the unexpected; the pronouncement of death; and the impact on self-caring within the family. The study complied with the ethical principles inherent to research involving humans. The unexpected news and death of the sick person influence the well-being and self-care of family members, affecting their ability for analysis and decision making. It was observed that the family experiences the news with suffering, mainly due to the anticipation arising from the events. The humanity of nurses was revealed in response to the needs of the family. In view of the requirements for information, it was verified that the information transmitted allowed them to become aware of themselves, to become empowered in their daily lives and to alleviate the emotional burden experienced.

    2017-01-01

    This qualitative study explored how adolescent boys with autism spectrum disorder experience their sexuality. Previous research has demonstrated that sexuality is a developmental task for boys with autism spectrum disorder, as it is for their peers. Case studies have suggested a relation between autism spectrum disorder and atypical sexual development; empirical studies on this subject, however, are scant and inconsistent. This study is based on interviews with eight boys, aged 16-20 years, with Asperger's disorder or autistic disorder. Interpretative phenomenological analysis of the data revealed three major themes relating to (a) how they experience sexual feelings, think about sexuality and think about themselves as sexual beings; (b) how they perceive messages relating to sexuality in their surroundings; and (c) how they experience finding and having a partner and partnered sex. We believe that attention to these themes is needed in assessment, education and further research. © The Author(s) 2016.

  11. Disentangling weak and strong interactions in B→ K^{*}(→ Kπ )π Dalitz-plot analyses

    2017-08-01

    Dalitz-plot analyses of B→ Kπ π decays provide direct access to decay amplitudes, and thereby weak and strong phases can be disentangled by resolving the interference patterns in phase space between intermediate resonant states. A phenomenological isospin analysis of B→ K^*(→ Kπ )π decay amplitudes is presented exploiting available amplitude analyses performed at the BaBar, Belle and LHCb experiments. A first application consists in constraining the CKM parameters thanks to an external hadronic input. A method, proposed some time ago by two different groups and relying on a bound on the electroweak penguin contribution, is shown to lack the desired robustness and accuracy, and we propose a more alluring alternative using a bound on the annihilation contribution. A second application consists in extracting information on hadronic amplitudes assuming the values of the CKM parameters from a global fit to quark flavour data. The current data yields several solutions, which do not fully support the hierarchy of hadronic amplitudes usually expected from theoretical arguments (colour suppression, suppression of electroweak penguins), as illustrated from computations within QCD factorisation. Some prospects concerning the impact of future measurements at LHCb and Belle II are also presented. Results are obtained with the CKMfitter analysis package, featuring the frequentist statistical approach and using the Rfit scheme to handle theoretical uncertainties.

  12. Nanosystem self-assembly pathways discovered via all-atom multiscale analysis.

    Pankavich, Stephen D; Ortoleva, Peter J

    2012-07-26

    We consider the self-assembly of composite structures from a group of nanocomponents, each consisting of particles within an N-atom system. Self-assembly pathways and rates for nanocomposites are derived via a multiscale analysis of the classical Liouville equation. From a reduced statistical framework, rigorous stochastic equations for population levels of beginning, intermediate, and final aggregates are also derived. It is shown that the definition of an assembly type is a self-consistency criterion that must strike a balance between precision and the need for population levels to be slowly varying relative to the time scale of atomic motion. The deductive multiscale approach is complemented by a qualitative notion of multicomponent association and the ensemble of exact atomic-level configurations consistent with them. In processes such as viral self-assembly from proteins and RNA or DNA, there are many possible intermediates, so that it is usually difficult to predict the most efficient assembly pathway. However, in the current study, rates of assembly of each possible intermediate can be predicted. This avoids the need, as in a phenomenological approach, for recalibration with each new application. The method accounts for the feedback across scales in space and time that is fundamental to nanosystem self-assembly. The theory has applications to bionanostructures, geomaterials, engineered composites, and nanocapsule therapeutic delivery systems.

  13. Testing the very-short-baseline neutrino anomalies at the solar sector

    2011-06-01

    Motivated by the accumulating hints of new sterile neutrino species at the eV scale, we explore the consequences of such an hypothesis on the solar sector phenomenology. After introducing the theoretical formalism needed to describe the Mikheyev-Smirnov-Wolfenstein conversion of solar neutrinos in the presence of one (or more) sterile neutrino state(s) located “far” from the (ν1, ν2) “doublet”, we perform a quantitative analysis of the available experimental results, focusing on the electron neutrino mixing. We find that the present data posses a sensitivity to the amplitude of the lepton mixing matrix element Ue4—encoding the admixture of the electron neutrino with a new mass eigenstate—which is comparable to that achieved on the standard matrix element Ue3. In addition, and more importantly, our analysis evidences that, in a 4-flavor framework, the current preference for |Ue3|≠0 is indistinguishable from that for |Ue4|≠0, having both a similar statistical significance (which is ˜1.3σ adopting the old reactor fluxes determinations, and ˜1.8σ using their new estimates.) We also point out that, differently from the standard 3-flavor case, in a 3+1 scheme the Dirac CP-violating phases cannot be eliminated from the description of solar neutrino conversions.

    We test the validity of statistical descriptions of freely decaying 2D turbulence by performing direct numerical simulations (DNS) of the Euler equation with hyperviscosity on a square torus and on a sphere.

    In the framework of severe accident research activity developed by ENEA, a MELCOR nodalization of a generic Pressurized Water Reactor of 900 MWe has been developed. The aim of this paper is to present the analysis of MELCOR code calculations concerning two independent unmitigated large break loss of coolant accident transients, occurring in the cited type of reactor. In particular, the analysis and comparison between the transients initiated by an unmitigated double-ended cold leg rupture and an unmitigated double-ended hot leg rupture in the loop 1 of the primary cooling system is presented herein. This activity has been performed focusing specifically on the in-vessel phenomenology that characterizes this kind of accidents. The analysis of the thermal-hydraulic transient phenomena and the core degradation phenomena is therefore here presented. The analysis of the calculated data shows the capability of the code to reproduce the phenomena typical of these transients and permits their phenomenological study. A first sequence of main events is here presented and shows that the cold leg break transient results faster than the hot leg break transient because of the position of the break. Further analyses are in progress to quantitatively assess the results of the code nodalization for accident management strategy definition and fission product source term evaluation.

    The evaluation of academic education has become crucial in the European Union since the Bologna Process encouraged all European universities to reach high quality standards in education. Although several studies have been conducted on the quality of undergraduate nursing education, few studies have explored this topic from the students' perspective. The purpose of this study was to describe the experience of educational quality in undergraduate nursing students. The phenomenological method was used to study 55 students (mean age 24 years; 73% female) pursuing a baccalaureate degree in nursing in three universities in central Italy. The following five themes emerged from the phenomenological analysis: 1) quality of faculties: teaching skills, preparation, sensitivity to students, self-discipline; 2) theory-practice integration and communication between teaching and clinical area; 3) general management and organization of the programme; 4) quality of infrastructures: libraries, classrooms, information technology, services, administration, and communication; and 5) clinical tutorship: humanity, relationships and ability of the clinical tutor to guide and support. This study's novel finding was a deeper understanding of the educational quality's meanings among undergraduate nursing students. Students thought educational quality consisted of the faculty members' sensitivity towards their problems and the clinical tutors' humanity, interpersonal skills, guidance and support.

  17. Development and psychometric properties of a new measure for memory phenomenology: The Autobiographical Memory Characteristics Questionnaire.

    The purpose of this study is to develop a valid and reliable measure for the phenomenology of autobiographical memories. The psychometric properties of the Autobiographical Memory Characteristics Questionnaire (AMCQ) were tested in three studies: the factor structure of the AMCQ was examined for childhood memories in Study 1 (N = 305); for autobiographical memories related to romantic relationships in Study 2 (N = 197); and for self-defining memories in Study 3 (N = 262). The explanatory factor analyses performed for each memory type demonstrated the consistency of the AMCQ factor structure across all memory types; while a confirmatory factor analysis on the data garnered from all three studies supported the constructs for the autobiographical memory characteristics defined by the researchers. The AMCQ consists of 63 items and 14 factors, and the internal consistency values of all 14 scales were ranged between .66 and .97. The relationships between the AMCQ scales related to gender and individual emotions, as well as the intercorrelations among the scales, were consistent with both theoretical expectations and previous findings. The results of all the three studies indicated that this new instrument is a reliable and robust measure for memory phenomenology.

    There is a growing need for community-based services for persons with Alzheimer's disease and related dementias (ADRD). Memory clinic (MC) teams in primary care settings have been established to provide care to people with ADRD. To consider wider adoption of these MC teams, insight is needed into the experiences of practitioners working in these models. The purpose of the current study is to explore the experiences of health care providers (HCPs) who work in primary care Memory Clinic (MC) teams to provide care to persons with Alzheimer's disease and related dementias (ADRD). This study utilized a phenomenological methodology to explore experiences of 12 HCPs in two primary care MCs. Semi-structured interviews were completed with each HCP. Interviews were recorded and transcribed verbatim. Colaizzi's steps for analyzing phenomenological data was utilized by the authors. Three themes emerged from the analysis to describe HCP experiences: supporting patients and family members during ADRD diagnosis and treatment, working in a team setting, and personal and professional rewards of caring for people with ADRD and their family members. Findings provide insight into current practices in primary care MCs and on the motivation of HCPs working with persons with ADRD.

    A lot of inconsistencies across dimensional studies of schizophrenia(s) are being unveiled. These problems are strongly related to the methodological aspects of collecting data and specific statistical analyses. Psychiatrists have developed lots of psychopathological models derived from analytic studies based on SAPS/SANS (the Scale for the Assessment of Positive Symptoms/the Scale for the Assessment of Negative Symptoms) and PANSS (The Positive and Negative Syndrome Scale). The unique validation of parallel two independent factor models was performed--ascribed to the same illness and based on different diagnostic scales--to investigate indirect methodological causes of clinical discrepancies. 100 newly admitted patients (mean age--33.5, 18-45, males--64, females--36, hospitalised on average 5.15 times) with paranoid schizophrenia (according to ICD-10) were scored and analysed using PANSS and SAPS/SANS during psychotic exacerbation. All patients were treated with neuroleptics of various kinds with 410mg equivalents of chlorpromazine (atypicals:typicals --> 41:59). Factor analyses were applied to basic results (with principal component analysis, normalised varimax rotation). Investing the cross-model validity, canonical analysis was applied. Models of schizophrenia varied from 3 to 5 factors. PANSS model included: positive, negative, disorganisation, cognitive and depressive components and SAPS/SANS model was dominated by positive, negative and disorganisation factors. The SAPS/SANS accounted for merely 48% of the PANSS common variances. The SAPS/SANS combined measurement preferentially (67% of canonical variance) targeted positive-negative dichotomy. Respectively, PANSS shared positive-negative phenomenology in 35% of its own variance. The general concept of five-dimensionality in paranoid schizophrenia looks clinically more heuristic and statistically more stabilised.

    Racher, Frances E; Robinson, Steven

    2003-08-01

    Researchers are advocating that a necessary condition of scholarly research is congruence between philosophical positions and research approaches. Phenomenology and postpositivism, traditionally, may appear to be situated in scientific inquiry as polar opposites and mutually exclusive paradigms. This article (a) describes the reflections of a nurse researcher and clarifies her philosophical assumptions; (b) delineates the postpositive paradigm and the interpretive paradigm, which traditionally includes phenomenology; (c) discusses phenomenology as a philosophy, an approach, and a research method; and (d) demonstrates the consistency between postpositivism and phenomenology. Nurse researchers must be aware of their philosophical assumptions and appraise the philosophical underpinnings of the methodologies, but this process should not restrict and limit their exploration of possibilities and the creativity in their efforts to address the growing challenges that await nursing science research.

    2016-05-01

    the purpose of this study was to explore mothers׳ experiences of embodied emotional sensations during breast feeding and to understand the meaning and consequences that such experiences may have on mothers' sense of self and the relationships they form with their children. a qualitative design was applied to this study as it was judged as the most appropriate approach to this novel field of enquiry. the study was conducted in United Kingdom using a sample of mothers drawn from five different countries from Europe, America and Australia. the sample consisted of 11 mothers who reported experiencing or having experienced negative embodied emotional sensations associated with breast feeding in the past five years. semi-structured interviews were conducted with the mothers and interviews were transcribed to enable the process of data analysis. Interpretative Phenomenological Analysis (IPA; Smith et al., 2009a, 2009b) was chosen as a method of data analysis, enabling in depth understanding and interpretation of the meaning of mothers' experiences. IPA was chosen due to its idiographic commitment and particular interest in sense-making, phenomenology and hermeneutics. three themes were generated reflecting the multifaceted nature of breast feeding experiences (i) 'Breast feeding: An unexpected trigger of intense embodied emotional sensations incongruent with view of self', (ii) 'Fulfilling maternal expectations and maintaining closeness with the child', (iii) 'Making sense of embodied emotional sensations essential to acceptance and coping'. breast feeding has the potential to trigger a range of conflicting cognitions and emotions in mothers that may impact on how mothers view themselves and relate to their children. increasing awareness about emotional breast feeding experiences and recognising the multifaceted, individual nature of difficulties around breast feeding enables professionals to offer mothers person-centred care and avoid making clinical decisions and recommendations based on inaccurate knowledge.

  3. Terahertz Systems Engineering: Detectors, Sources, Propagation, Phenomenology, Design and Analysis

    NASA Astrophysics Data System (ADS)

    Suen, Jonathan Ying-Yan

    The terahertz (THz) band, from 300 GHz to 20 THz, is the last remaining frontier of the electromagnetic spectrum. Fundamentally, the frequency is too high to use current electronic technologies, yet the photon energy is too low for optical systems. However, there is a rich set of phenomenology, science, and applications, which are only available with THz radiation. In order to exploit this, the THz engineer who is designing systems must be adept at integrating components with very limited performance into a system. This requires understanding and knowledge of a wide range of fields, including microwaves, infrared optics, material science, software development, atmospheric science, and the overall analysis and design of a system. Any THz system involves the sensing of some phenomena, which can be under the direct control of the engineer, such as in a communication system, or set by the laws of physics, such as in an astronomical telescope, or some variant in between. Thus, the design of such a system is fundamentally related to sensing science. Here, we have to consider detector and source technology, the propagation of radiation, target phenomenology, and the overall design and analysis of the system. This dissertation presents research in all of these areas. Specifically, in the field of THz phenomenology, I conducted a study to show the primary contrast mechanism in reflective biomedical imaging is water concentration. For source technology, I detail the development and characterization of photoconductive switches with record-breaking optical efficiency. In a separate study I developed a model which explains the complex photocarrier dynamics in fast-trapping THz photoconductive materials and show that high-frequency THz generation (>1 THz) is caused by beaching saturation. My work in detectors shows the design of a quasi-optical radar that exploits low 1/f noise Schottky diodes for detection of slow moving objects, useful for biomedical sensing of respiration and heartbeat. In the field of THz propagation, I have located low atmospheric water vapor sites and characterized THz attenuation on a global scale with satellite remote sensing data. Finally, I show the analysis of a full system by showing 300-gigabit level THz ground to geostationary satellite links to moderately dry global locations. All of these works were published or submitted for publication. These projects inherently involved multidisciplinary research though they all were targeted towards the THz regime. The research in this dissertation exemplifies the broad knowledge and diverse fields that must be synergized to build effective THz systems and advance science in the THz domain.

    The human body is the object upon which medicine is acting, but also lived reality, image, symbol, representation and the object of elaboration and theory. All these elements which constitute the body influence the way medicine is treating it. In this series of three articles, we address the human body from various perspectives: medical (1), phenomenological (2), psychosomatic and socio-anthropological (3). This first article discusses four distinct types of representation of the body within medicine, each related to a specific epistemology and shaping a distinct kind of clinical legitimacy: the body-object of anatomy, the body-machine of physiology, the cybernetic body of biology, the statistical body of epidemiology.

    Falls, Kevin; Litim, Daniel F.

    2014-04-01

    A coarse-grained version of the effective action is used to study the thermodynamics of black holes, interpolating from largest to smallest masses. The physical parameters of the black hole are linked to the running couplings by thermodynamics, and the corresponding equation of state includes quantum corrections for temperature, specific heat, and entropy. If quantum gravity becomes asymptotically safe, the state function predicts conformal scaling in the limit of small horizon area and bounds on black hole mass and temperature. A metric-based derivation for the equation of state and quantum corrections to the thermodynamical, statistical, and phenomenological definition of entropy are also given. Further implications and limitations of our study are discussed.

    PubMed

    Pool, Natalie M

    2018-07-01

    Engaging in early and ongoing self-reflection during interpretive phenomenological research is critical for ensuring trustworthiness or rigor. However, the lack of guidelines and clarity about the role of self-reflection in this methodology creates both theoretical and procedural confusion. The purpose of this article is to describe key philosophical underpinnings, characteristics, and hallmarks of the process of self-reflection in interpretive phenomenological investigation and to provide a list of guidelines that facilitate this process. Excerpts from an interpretive phenomenological study are used to illustrate characteristics of quality self-reflection. The guidelines are intended to be particularly beneficial for novice researchers who may find self-reflective writing to be daunting and unclear. Facilitating use of self-reflection may strengthen both the interpretive phenomenological body of work as well as that of all qualitative research.

    2011-01-01

    Incarcerated women face a number of stressors apart from the actual incarceration. Nearly half of all women in prison experience the death of a loved one during their incarceration. Our purpose for this study was to explore the experience of grief and loss among incarcerated women using a phenomenological method. Our study approach followed van Manen's method of phenomenology and Munhall's description of existential lifeworlds. Our analysis revealed four existential lifeworlds: temporality: frozen in time; spatiality: no place, no space to grieve; corporeality: buried emotions; and relationality: never alone, yet feeling so lonely. The findings generated from this study can help mental health providers as well as correctional professionals develop policies and programs that facilitate the grief process of incarcerated women within the confines of imprisonment.

    The purpose of this qualitative, phenomenological study is to describe dimensions of caring as they relate to and clarify the practice of professional nursing. Nurses are unique caregivers, and their work at the bedside and in the community matters. What nurses do as they care for patients is multi-dimensional, complex, and essential. Two hundred stories written by nurses were analyzed using Giorgi's methodology for existential phenomenology. Their stories indicate that nursing goes far beyond technical skills. Seven dimensions of caring that define professional nursing practice were found: caring, compassion, spirituality, community outreach, providing comfort, crisis intervention, and going the extra distance. The nurses' stories demonstrate that the dimensions of caring that define professional nursing practice are universal. Documentation of nurse's stories facilitates reflective and thoughtful practice, while clarifying the essential components of nursing.

  16. Ice can look like glass: a phenomenological investigation of movement meaning in one fifth-grade class during a creative dance unit.

    2004-09-01

    The movement meanings of students (n = 19) in one fifth-grade class during a creative dance unit focusing on effort (force, time, space, flow) are investigated using a perspective grounded in transcendental phenomenology (Husserl, 1931). Data were collected via videotape, journal, and homework documents and semistructured interviews. Analytical induction (Patton, 2002) structured a four-step analysis process that reduced meaning to its essential essence. Movement meaning was found to be a multifaceted construct that varied among students within and across five dimensions. To enhance meaningful learning, educators are encouraged to consider reflexively (a) their philosophical orientation relative to knowledge making and curriculum values, (b) instructional techniques that help students' access meaning, and (c) the contribution of dance as a source of meaning.

  17. Being the stranger: Comparing study abroad experiences of nursing students in low and high income countries through hermeneutical phenomenology.

    To understand the experience of American nursing students who complete a study abroad trip to a low-income country, Bangladesh, versus a high-income country, the Netherlands in the development of cultural consciousness. Hermeneutic (interpretive) phenomenology was used to explore the journals of 44 students' experiences and reflections. The comprehensive understanding of the naïve and structural analysis revealed that, no matter where these students travelled, they increased their cultural consciousness. We need to revise curricula to create 'change from the familiar' experiences for all students (many cannot afford study abroad) to move students to cultural consciousness on their journey to cultural competency that may improve client health outcomes.

  18. The cruel and unusual phenomenology of solitary confinement.

    Gallagher, Shaun

    2014-01-01

    What happens when subjects are deprived of intersubjective contact? This paper looks closely at the phenomenology and psychology of one example of that deprivation: solitary confinement. It also puts the phenomenology and psychology of solitary confinement to use in the legal context. Not only is there no consensus on whether solitary confinement is a "cruel and unusual punishment," there is no consensus on the definition of the term "cruel" in the use of that legal phrase. I argue that we can find a moral consensus on the meaning of "cruelty" by looking specifically at the phenomenology and psychology of solitary confinement.

  19. The detection of the imprint of filaments on cosmic microwave background lensing

    2018-05-01

    Galaxy redshift surveys, such as the 2-Degree-Field Survey (2dF)1, Sloan Digital Sky Survey (SDSS)2, 6-Degree-Field Survey (6dF)3, Galaxy And Mass Assembly survey (GAMA)4 and VIMOS Public Extragalactic Redshift Survey (VIPERS)5, have shown that the spatial distribution of matter forms a rich web, known as the cosmic web6. Most galaxy survey analyses measure the amplitude of galaxy clustering as a function of scale, ignoring information beyond a small number of summary statistics. Because the matter density field becomes highly non-Gaussian as structure evolves under gravity, we expect other statistical descriptions of the field to provide us with additional information. One way to study the non-Gaussianity is to study filaments, which evolve non-linearly from the initial density fluctuations produced in the primordial Universe. In our study, we report the detection of lensing of the cosmic microwave background (CMB) by filaments, and we apply a null test to confirm our detection. Furthermore, we propose a phenomenological model to interpret the detected signal, and we measure how filaments trace the matter distribution on large scales through filament bias, which we measure to be around 1.5. Our study provides new scope to understand the environmental dependence of galaxy formation. In the future, the joint analysis of lensing and Sunyaev-Zel'dovich observations might reveal the properties of `missing baryons', the vast majority of the gas that resides in the intergalactic medium, which has so far evaded most observations.

    Employing data collected during the first 25 months of observations by the Fermi-LAT, we describe and subsequently seek to model the very high energy (>300 MeV) emission from the central few parsecs of our Galaxy. We analyze the morphological, spectral, and temporal characteristics of the central source, 1FGL J1745.6-2900. The data show a clear, statistically significant signal at energies above 10 GeV, where the Fermi-LAT has angular resolution comparable to that of HESS at TeV energies. This makes a meaningful joint analysis of the data possible. Our analysis of the Fermi data (alone) does not uncover any statistically significant variabilitymore » of 1FGL J1745.6-2900 at GeV energies on the month timescale. Using the combination of Fermi data on 1FGL J1745.6-2900 and HESS data on the coincident, TeV source HESS J1745-290, we show that the spectrum of the central gamma-ray source is inflected with a relatively steep spectral region matching between the flatter spectrum found at both low and high energies. We model the gamma-ray production in the inner 10 pc of the Galaxy and examine cosmic ray (CR) proton propagation scenarios that reproduce the observed spectrum of the central source. We show that a model that instantiates a transition from diffusive propagation of the CR protons at low energy to almost rectilinear propagation at high energies can explain well the spectral phenomenology. We find considerable degeneracy between different parameter choices which will only be broken with the addition of morphological information that gamma-ray telescopes cannot deliver given current angular resolution limits. We argue that a future analysis performed in combination with higher-resolution radio continuum data holds out the promise of breaking this degeneracy.« less

    The creative processes of understanding patients' experiences in phenomenological research are difficult to articulate. Drawing on life philosophy as represented by the Danish philosopher K.E. Løgstrup (1905-1981), this article aims to illustrate Løgstrup's thinking as a way to elaborate the creation of cognition and understanding of patients' experiences. We suggest that Løgstrup's thoughts on sensation can add new dimensions to an increased understanding of the creative process of phenomenological research, and that his thinking can be seen as an epistemological ground for these processes. We argue with Løgstrup that sense-based impressions can facilitate an flash of insight, i.e., the spontaneous, intuitive flash of an idea. Løgstrup stresses that an "flash of insight" is an important source in the creation of cognition and understanding. Relating to three empirical phenomenological studies of patients' experiences, we illustrate how the notions of impression and flash of insight can add new dimensions to increased understanding of the creative processes in phenomenological research that have previously not been discussed. We illustrate that sense-based impressions can facilitate creative flash of insights that open for understanding of patients' experiences in the research process as well as in the communication of the findings. The nature of impression and flash of insight and their relevance in the creation of cognition and understanding contributes to the sparse descriptions in the methodological phenomenological research literature of the creative processes of this research. An elaboration of the creative processes in phenomenological research can help researchers to articulate these processes. Thus, Løgstrup's life philosophy has proven to be valuable in adding new dimensions to phenomenological empirical research as well as embracing lived experience.

  15. Theory and modelling of light-matter interactions in photonic crystal cavity systems coupled to quantum dot ensembles

    NASA Astrophysics Data System (ADS)

    Cartar, William K.

    Photonic crystal microcavity quantum dot lasers show promise as high quality-factor, low threshold lasers, that can be integrated on-chip, with tunable room temperature opera- tions. However, such semiconductor microcavity lasers are notoriously difficult to model in a self-consistent way and are primarily modelled by simplified rate equation approxima- tions, typically fit to experimental data, which limits investigations of their optimization and fundamental light-matter interaction processes. Moreover, simple cavity mode optical theory and rate equations have recently been shown to fail in explaining lasing threshold trends in triangular lattice photonic crystal cavities as a function of cavity size, and the potential impact of fabrication disorder is not well understood. In this thesis, we develop a simple but powerful numerical scheme for modelling the quantum dot active layer used for lasing in these photonic crystal cavity structures, as an ensemble of randomly posi- tioned artificial two-level atoms. Each two-level atom is defined by optical Bloch equations solved by a quantum master equation that includes phenomenological pure dephasing and an incoherent pump rate that effectively models a multi-level gain system. Light-matter in- teractions of both passive and lasing structures are analyzed using simulation defined tools and post-simulation Green function techniques. We implement an active layer ensemble of up to 24,000 statistically unique quantum dots in photonic crystal cavity simulations, using a self-consistent finite-difference time-domain method. This method has the distinct advantage of capturing effects such as dipole-dipole coupling and radiative decay, without the need for any phenomenological terms, since the time-domain solution self-consistently captures these effects. Our analysis demonstrates a powerful ability to connect with recent experimental trends, while remaining completely general in its set-up; for example, we do not invoke common approximations such as the rotating-wave or slowly-varying envelope approximations, and solve dynamics with zero a priori knowledge.

  16. The effectiveness of a programme of enhancing resiliency by reducing family boundary ambiguity among children with epilepsy.

    PubMed

    Mu, Pei-Fan; Chang, Kai-Ping

    2010-05-01

    The aim of the study was to examine the effect of a programme designed to reduce family boundary ambiguity in families who care for children with epilepsy. When parents are caring for an epileptic child, they may experience unclear perceptions about whether the child is psychologically included in the family and develop unclear expectations regarding role performance in the family. Some studies have identified boundary ambiguity as a possible antecedent to relationship problems that are associated with negative outcomes in the areas of parental well-being and family functioning. There is a need to develop family nursing interventions that will reduce family boundary ambiguity when the family is caring for children with epilepsy. A pretest, post-test, one group, quasi-experimental design was used in this study. This study was made up of three phases: first, the establishing of a parental needs checklist and the development of a parental education information handbook; second, the carrying out of a family assessment including the analysis of the meaning of their experiences and needs and the construction of an educational dialogue and finally, an outcomes evaluation after three months. Seventeen mothers participated in the study. The study found that there were statistically significant improvements in family boundary ambiguity and maternal depression was reduced. This study illustrates nursing intervention that involves the integrating of phenomenological principles into the nursing care process. Specifically, Husserlian phenomenology is able to be helpful to nursing practice, especially the concepts of intentionality, intersubjectivity, empathy and bracketing. This study supported the conceptual framework involved in the construction of the meaning of the situation, the enhancement of mastery over the situation and reconstruction of identity. These items are resiliency factors that provided a mechanism that helps to reduce boundary ambiguity when a family is caring for a child with epilepsy.

    2016-01-01

    Objective The primary aim of this study was to examine first-person phenomenological descriptions of the relationship between the self and Auditory Verbal Hallucinations (AVHs). Complex AVHs are frequently described as entities with clear interpersonal characteristics. Strikingly, investigations of first-person (subjective) descriptions of the phenomenology of the relationship are virtually absent from the literature. Method Twenty participants with psychosis and actively experiencing AVHs were recruited from the University of Illinois at Chicago. A mixed-methods design involving qualitative and quantitative components was utilized. Following a priority-sequence model of complementarity, quantitative analyses were used to test elements of emergent qualitative themes. Results The qualitative analysis identified three foundational constructs in the relationship between self and voices: ‘understanding of origin,’ ‘distinct interpersonal identities,’ and ‘locus of control.’ Quantitative analyses further supported identified links of these constructs. Subjects experienced their AVHs as having identities distinct from self and actively engaged with their AVHs experienced a greater sense of autonomy and control over AVHs. Discussion Given the clinical importance of AVHs and emerging strategies targeting the relationship between the hearer and voices, our findings highlight the importance of these relational constructs in improvement and innovation of clinical interventions. Our analyses also underscore the value of detailed voice assessments such as those provided by the Maastricht Interview are needed in the evaluation process. Subjects narratives shows that the relational phenomena between hearer and AVH(s) is dynamic, and can be influenced and changed through the hearers’ engagement, conversation, and negotiation with their voices.

    The psychosis-proneness-persistence-impairment model of psychotic disorder incorporates notions of both phenomenological and temporal continuity (persistence) of psychotic experiences (PE), but not structural continuity. Specific testable propositions of phenomenological continuity and persistence are identified. Method Propositions are tested by systematic reviews of the epidemiology of PE, persistence of PE and disorder outcomes, and meta-analyses (including Monte Carlo permutation sampling, MCPS) of reported rates and odds ratios (ORs). Estimates of the incidence and prevalence of PE obtained from 61 cohorts revealed a median annual incidence of 2.5% and a prevalence of 7.2%. Meta-analysis of risk factors identified age, minority or migrant status, income, education, employment, marital status, alcohol use, cannabis use, stress, urbanicity and family history of mental illness as important predictors of PE. The mode of assessment accounted for significant variance in the observed rates. Across cohorts, the probability of persistence was very strongly related to the rate of PE at baseline. Of those who report PE, ∼20% go on to experience persistent PE whereas for ∼80%, PE remit over time. Of those with baseline PE, 7.4% develop a psychotic disorder outcome. Compelling support is found for the phenomenological and temporal continuity between PE and psychotic disorder and for the fundamental proposition that this relationship is probabilistic. However, imprecision in epidemiological research design, measurement limitations and the epiphenomenological nature of PE invite further robust scrutiny of the continuity theory.

    To explore carers' experience of caring during a mental health crisis. Community mental health care including crisis care relies increasingly on carers. The relationship between carers and professionals is at times fraught due to issues of what constitutes a crisis, confidentiality and a perception of lack of empathy. The caring experience can lead carers to feel isolated and neglected. A qualitative study with a phenomenological approach. Eight carers participated and were interviewed individually using a semi-structured approach. Analysis used the Interpretive Phenomenological Analysis method including transcribing of interviews, initial noting, searching for connections and patterns across the transcripts and cases. The themes were checked with the participants for their views on the emerging themes. The data were collected from November 2011-May 2012. Carers experienced 'double deprivation' by not receiving support from professionals and protecting their social network from the trauma of the crisis. The caring in crisis invoked complex feelings of guilt and loyalty which made discussing aggression difficult. Caring was described as a terrifying experience not just because of the aggression but also because of the perception of abandonment by professionals. The experience was an overwhelmingly negative one with a wish for acknowledgement of the crisis and support from mental health services. For most of the participants the caring during crisis was traumatic which left the carer feeling isolated and unsupported. The study should be used to help educate professionals on the complexities of caring during a crisis. © 2015 John Wiley & Sons Ltd.

    This study explored the process of recovery from bipolar I disorder from a phenomenological and cognitive perspective. A semi-structured interview was coded and analysed using interpretative phenomenological analysis. Eleven individuals over the age of 30 with a history of bipolar disorder were selected on the basis of having remained free from relapse, and without hospitalization for at least 2 years, as confirmed by a diagnostic interview (Standardised Interview for DSM-IV; SCID-I). This arbitrary and equivocal criterion for 'recovery' provided an objective method of defining the sample for the study. The analysis revealed two overarching themes formed from four themes each. Ambivalent approaches referred to approaches that participants felt had both positive and negative consequences: avoidance of mania, taking medication, prior illness versus current wellness, and sense of identity following diagnosis. Helpful approaches referred to approaches that were seen as universally helpful: understanding, life-style fundamentals, social support and companionship, and social change. These themes were then interpreted in the light of the existing literature and an integrative cognitive model of bipolar disorder. Limitations and future research directions are discussed.

  1. Automated Systematic Generation and Exploration of Flat Direction Phenomenology in Free Fermionic Heterotic String Theory

    NASA Astrophysics Data System (ADS)

    Greenwald, Jared

    Any good physical theory must resolve current experimental data as well as offer predictions for potential searches in the future. The Standard Model of particle physics, Grand Unied Theories, Minimal Supersymmetric Models and Supergravity are all attempts to provide such a framework. However, they all lack the ability to predict many of the parameters that each of the theories utilize. String theory may yield a solution to this naturalness (or self-predictiveness) problem as well as offer a unifed theory of gravity. Studies in particle physics phenomenology based on perturbative low energy analysis of various string theories can help determine the candidacy of such models. After a review of principles and problems leading up to our current understanding of the universe, we will discuss some of the best particle physics model building techniques that have been developed using string theory. This will culminate in the introduction of a novel approach to a computational, systematic analysis of the various physical phenomena that arise from these string models. We focus on the necessary assumptions, complexity and open questions that arise while making a fully-automated at direction analysis program.

    HIV-related stigma is a major driver of poor prognosis for the treatment and reduced spread of HIV. The present article provides a qualitative analysis surrounding various themes related to stigma and shame as a result HIV. Eight gay men recruited from a community HIV clinic contacted the researchers in response to a study involving participation in a structured, eight-week group intervention for HIV-related stigma. Following this group, three men took part in open-ended interviews about their thoughts and experiences. Interpretative phenomenological analysis was used to examine the participants' experiences surrounding shame and stigma related to living with HIV. Three superordinate themes were identified: social support and the disclosure of serostatus, stigma associated with serosorting and attempts to negotiate a spoiled identity. In San Francisco, a city with a great deal of acceptance surrounding HIV and a large, politically active community of persons living with HIV, gay men continue to struggle with disclosure and stigma. This stigma may be an unexpected result of a high degree of HIV testing and attempts by both HIV-positive and negative gay men to practise serosorting.

  3. No departure to "Pandora"? Using critical phenomenology to differentiate "naive" from "reflective" experience in psychiatry and psychosomatic medicine (A comment on Schwartz and Wiggins, 2010)

    PubMed Central

    2010-01-01

    The mind-body problem lies at the heart of the clinical practice of both psychiatry and psychosomatic medicine. In their recent publication, Schwartz and Wiggins address the question of how to understand life as central to the mind-body problem. Drawing on their own use of the phenomenological method, we propose that the mind-body problem is not resolved by a general, evocative appeal to an all encompassing life-concept, but rather falters precisely at the insurmountable difference between "natural" and a "reflective" experience built into phenomenological method itself. Drawing on the works of phenomenologically oriented thinkers, we describe life as inherently "teleological" without collapsing life with our subjective perspective, or stepping over our epistemological limits. From the phenomenology it can be demonstrated that the hypothetical teleological qualities are a reflective reconstruction modelled on human behavioural structure. PMID:21040525

    When one considers a phenomenon that is "complex" refers to a system whose phenomenological laws that describe the global behavior of the system, are not necessarily directly related to the "microscopic" laws that regulate the evolution of its elementary parts. The field of study of complex systems considers that the dynamics of complex systems are founded on universal principles that may be used to describe disparate problems ranging from particle physics to economies of societies. Several authors have suggested that earthquake (EQ) dynamics can be analyzed within similar mathematical frameworks with economy dynamics, and neurodynamics. A central property of the EQ preparation process is the occurrence of coherent large-scale collective behavior with a very rich structure, resulting from repeated nonlinear interactions among the constituents of the system. As a result, nonextensive statistics is an appropriate, physically meaningful, tool for the study of EQ dynamics. Since the fracture induced electromagnetic (EM) precursors are observable manifestations of the underlying EQ preparation process, the analysis of a fracture induced EM precursor observed prior to the occurrence of a large EQ can also be conducted within the nonextensive statistics framework. Within the frame of the investigation for universal principles that may hold for different dynamical systems that are related to the genesis of extreme events, we present here statistical similarities of the pre-earthquake EM emissions related to an EQ, with the pre-ictal electrical brain activity related to an epileptic seizure, and with the pre-crisis economic observables related to the collapse of a share. It is demonstrated the all three dynamical systems' observables can be analyzed in the frame of nonextensive statistical mechanics, while the frequency-size relations of appropriately defined "events" that precede the extreme event related to each one of these different systems present striking quantitative similarities. It is also demonstrated that, for the considered systems, the nonextensive parameter q increases as the extreme event approaches, which indicates that the strength of the long-memory / long-range interactions between the constituents of the system increases characterizing the dynamics of the system.

    What happens when subjects are deprived of intersubjective contact? This paper looks closely at the phenomenology and psychology of one example of that deprivation: solitary confinement. It also puts the phenomenology and psychology of solitary confinement to use in the legal context. Not only is there no consensus on whether solitary confinement is a “cruel and unusual punishment,” there is no consensus on the definition of the term “cruel” in the use of that legal phrase. I argue that we can find a moral consensus on the meaning of “cruelty” by looking specifically at the phenomenology and psychology of solitary confinement. PMID:24971072

    Performance prediction of off-axis laminates is of significant interest in designing composite structures for energy absorption. Phenomenological models available in most of the commercial programs, where the fiber and resin properties are smeared, are very efficient for large scale structural analysis, but lack the ability to model the complex nonlinear behavior of the resin and fail to capture the complex load transfer mechanisms between the fiber and the resin matrix. On the other hand, high fidelity mesoscale models, where the fiber tows and matrix regions are explicitly modeled, have the ability to account for the complex behavior in each of the constituents of the composite. However, creating a finite element model of a larger scale composite component could be very time consuming and computationally very expensive. In the present study, a three-dimensional mesoscale model of non-crimp composite laminates was developed for various laminate schemes. The resin material was modeled as an elastic-plastic material with nonlinear hardening. The fiber tows were modeled with an orthotropic material model with brittle failure. In parallel, new stress based failure criteria combined with several damage evolution laws for matrix stresses were proposed for a phenomenological model. The results from both the mesoscale and phenomenological models were compared with the experiments for a variety of off-axis laminates.

    This study explores the experience of the diagnosis of Multiple Sclerosis for the support person and identifies the impact on their lives. At the time of diagnosis, the support person may not be readily identified in a traditional caring role; however, the diagnosis itself brings with it the possibility of changes to the roles in the relationship and possible consequences for biographical construction. A hermeneutic phenomenological study. A convenience sample of nine support persons was interviewed between December 2008-March 2010. The data were analysed using interpretative phenomenological analysis. The participants in this study were often not readily identifiable as 'carers'; however, the diagnosis of Multiple Sclerosis implied a shift towards a caring role at some point in the future. The uncertainty surrounding the nature and progression of the condition left this identity hanging, incomplete and as such contributed to a liminal way of being. This paper reveals that biographical disruption is not limited to the person diagnosed with Multiple Sclerosis but that the support person also undergoes a transition to their sense of self to that of 'anticipatory carer'. The findings provide insight into the biographical and emotional impact of Multiple Sclerosis on the support persons early in the development of the condition. © 2015 John Wiley & Sons Ltd.

    This paper reports the findings of research on the lived experience of fatigue in patients with primary biliary cirrhosis - a type of chronic liver disease. Fatigue is a universal phenomenon, commonly associated with both acute and chronic illness, but also seen in healthy individuals. However, it is not often addressed in healthcare encounters despite its disabling nature, perhaps because of the multitude of contributing factors and the lack of effective treatments. It is a common and debilitating symptom in patients with primary biliary cirrhosis. Despite the prevalence of fatigue in this condition, patients' experiences of this symptom have not been researched. An interpretive-phenomenological approach developed by van Manen was chosen and this combines features of descriptive and interpretive phenomenology. Eight participants were interviewed during 2005 about their fatigue experience. Thematic analysis was conducted. Five themes were identified: an unreliable body, fatigue as always present yet insidious, planning a life to conserve energy, struggling to maintain normality and emotional consequences. These themes reflected the unrelenting, intrusive nature of fatigue into the lives of those affected. This research will provide empathic insight into the fatigue experience in this condition and generate communication about coping strategies. It will add to the body of research on fatigue in chronic conditions and may generate ideas for intervention research.

    Background/Aims This paper reports on analyses designed to elucidate phenomenological characteristics, content and experience specifically targeting participants with Schneiderian voices conversing/commenting (VC) while exploring difference in clinical presentation and quality of life compared to those with voices not conversing (VNC). Methods This mixed-method investigation of Schneiderian voices included standardized clinical metrics and exploratory phenomenological interviews designed to elicit in-depth information about characteristics, content, meaning and personification of AVHs. Results The subjective experience of VC show a striking pattern of VC that are experienced as internal at initial onset and during longer-term course of illness when compared to the VNC group. Participants in the VC group were more likely to attribute origins of their voices to an external source such as God, telepathic communication, or mediumistic sources. VC and VNC were described as characterological entities that were distinct from self (I/we versus you). We also found an association between VC and positive, cognitive, and depression symptom profile. However, we did not find a significant group difference in overall quality of life. Conclusions The clinical portrait of VC is complex, multisensory, and distinct, and suggests a need for further research into biopsychosocial interface between subjective experience, socioenvironmental constraints, individual psychology, and biological architecture of intersecting symptoms.

    Hwang, Sungwon; Roth, Wolff-Michael

    2008-12-01

    In this study, we propose a set of concepts for conceptualizing issues of learning science related to globalization, the encounter with the (radically) foreign/strange—as this occurs as part of migration and even as part of the encounter of a learner with the unknown content that science lessons are to impart—from the perspective of the experiencing person and the experience. We take an approach to the question of the foreign/strange that is grounded in philosophies of difference, which have emerged in continental Europe, and which make use of advances in phenomenology, dialectics, and materialism. We draw on ethnographic work in one undergraduate physics course at a Canadian university, where we followed in particular one female Japanese student, who had come to this country for the purpose of getting a degree. As an entry point and as source of empirical materials, we draw on our own auto/ethnographic experience that brings particular advantages to ally pathos to the experience of the foreign/strange, something is happening to (affecting) us that is beyond all experience, understanding, and anticipation. We articulate three phenomenological aspects that pathos (empathy) allows us to understand concerning the experience of the foreign/strange and then provide an exemplary and exemplifying analysis.

    Several mechanobiology algorithms have been employed to simulate bone ingrowth around porous coated implants. However, there is a scarcity of quantitative comparison between the efficacies of commonly used mechanoregulatory algorithms. The objectives of this study are: (1) to predict peri-acetabular bone ingrowth using cell-phenotype specific algorithm and to compare these predictions with those obtained using phenomenological algorithm and (2) to investigate the influences of cellular parameters on bone ingrowth. The variation in host bone material property and interfacial micromotion of the implanted pelvis were mapped onto the microscale model of implant-bone interface. An overall variation of 17-88 % in peri-acetabular bone ingrowth was observed. Despite differences in predicted tissue differentiation patterns during the initial period, both the algorithms predicted similar spatial distribution of neo-tissue layer, after attainment of equilibrium. Results indicated that phenomenological algorithm, being computationally faster than the cell-phenotype specific algorithm, might be used to predict peri-prosthetic bone ingrowth. The cell-phenotype specific algorithm, however, was found to be useful in numerically investigating the influence of alterations in cellular activities on bone ingrowth, owing to biologically related factors. Amongst the host of cellular activities, matrix production rate of bone tissue was found to have predominant influence on peri-acetabular bone ingrowth.

  13. Study of 11Li+p elastic scattering using BHF formalism with three body force

    2018-04-01

    In the present work we have analyzed the elastic scattering data of 11Li + p at 62, 68.4 and 75 MeV/nucleon, using the microscopic optical potential calculated within the framework of Brueckner-Hartree-Fock formalism (BHF). The calculation uses Argonne v18 and Urbana v14 inter-nucleon potentials and the Urbana IX (UVIX) model of three body force. The required nucleon-density distributions for 11Li are obtained using the semi-phenomenological model for nuclear density distributions. The optical potential has been obtained by folding the g-matrices as calculated in BHF (with and without three body forces) over the nucleon density distributions. We have used the exact method for calculating both the direct and the exchange parts of the spin-orbit potential. Our results reveal that the spin-orbit potential significantly contributes to 11Li+p elastic scattering at all three incident energies. Further, the calculated spin-orbit potential in BHF is much smaller and more diffused as compared with the phenomenological spin-orbit potential. The analysis reveals that the calculated microscopic optical potentials, with and without three body force using BHF approach with phenomenological form of density distribution, provides satisfactory agreement with the elastic scattering data for 11Li+p.

    The purpose of this research was to explore ICU nurses' perceptions of nursing leadership in the adult intensive care unit (ICU). The nursing profession needs leaders at all levels; ward, administration and executive and in an era in which there is a shortage of ICU nurses, nursing leadership is important, as positive leadership skills correlate with enhanced recruitment and retention of these specialist nurses. Six ICU nurses with at least 5 years experience in ICU nursing were recruited from a metropolitan hospital in Australia. Qualitative phenomenological methodology was used to depict the lived experiences of nurses' leadership in the adult ICU. Data were collected through individual semi-structured interviews using open-ended questions and analysed using Giorgi's [Giorgi A. Toward phenomenologically based research in psychology. J Phenomenol Psychol 1970;1:75-98] descriptive method for data analysis. Five themes emerged and these were all inter-related: leading by example, communication, ability to think outside the management square, knowing your staff and stepping up in times of crisis. These findings highlight the importance of nursing leadership in the adult ICU and the need to ensure that all current and future nursing ICU leaders are adequately prepared and educated for this role. This information may also be used to assist in the development of leadership skills in ICU nurses.

    This paper is focused on the characterization of the frequency content of vibration signals issued from a two-stage planetary gearbox. To achieve this goal, two different methodologies are adopted: the lumped-parameter modeling approach and the phenomenological modeling approach. The two methodologies aim to describe the complex vibrations generated by a two-stage planetary gearbox. The phenomenological model describes directly the vibrations as measured by a sensor fixed outside the fixed ring gear with respect to an inertial reference frame, while results from a lumped-parameter model are referenced with respect to a rotating frame and then transferred into an inertial reference frame. Two different case studies of the two-stage planetary gear are adopted to describe the vibration and the corresponding spectra using both models. Each case presents a specific geometry and a specific spectral structure.

    Admission of a child to the paediatric intensive care unit (PICU) may be one of the most stressful events for parents because the outcome is often uncertain. So how do parents cope, and how can we as nurses help them? To explore the lived experiences of parents whose children have been admitted to a PICU. Using Heidegger's school of interpretative phenomenology, six unstructured interviews were conducted. These were transcribed and analysed following interpretative phenomenological analysis. Participants were chosen through purposive sampling. Each participant had different emergent themes. Themes included trauma, responsibility, anxiety about where the child is, post-traumatic stress symptoms and transfer to the ward. The lived experience of a parent is fraught with varying different emotions, with the beginning of the journey and the ending of the PICU admission causing the most anxiety.

    This phenomenological study aimed to reveal the meaning of providing care to victims of sexual violence. The study was carried out from December 2006 to March 2007 with 12 health professionals. Data were collected through tape-recorded semi-structured interviews, whose analysis followed the phenomenological trajectory. The following theme emerged: Feeling powerless, a feeling expressed by caregivers of sexual violence victims. The feeling of powerlessness is continuously fed by health professionals' daily routines, given the impossibility of solving situations of violence, of problems that emerge from the other's subjectivity, as well as social issues, because these professionals were not trained for that. Thus, it is essential to address the issue both in undergraduate and graduate programs in health and human areas. Institutions should promote continuing education so that these professionals can act properly.

    The experimental data on elastic and inelastic scattering of 270 MeV 3He particles to several low lying states in 90Zr, 116Sn and 208Pb are analyzed within the double folding model (DFM). Fermi density distribution (FDD) of target nuclei is used to obtain real potentials with different powers. DF results are introduced into a modified DWUCK4 code to calculate the elastic and inelastic scattering cross sections. Two choices of potentials form factors are used; Woods Saxon (WS) and Woods Saxon Squared (WS2) for real potential, while the imaginary part is taken as phenomenological Woods Saxon (PWS) and phenomenological Woods Saxon Squared (PWS2). This comparison provides information about the similarities and differences of the models used in calculations.

    A phenomenological analysis of the three-family model based on the local gauge group SU(3)_c⊗ SU(3)_L⊗ U(1)_X with right-handed neutrinos is carried out. Instead of using the minimal scalar sector able to break the symmetry in a proper way, we introduce an alternative set of four Higgs scalar triplets, which combined with an anomaly-free discrete symmetry, produces a quark mass spectrum without hierarchies in the Yukawa coupling constants. We also embed the structure into a simple gauge group and show some conditions for achieving a low energy gauge coupling unification, avoiding possible conflict with proton decay bounds. By using experimental results from the CERN-LEP, SLAC linear collider, and atomic parity violation data, we update constraints on several parameters of the model.

    2018-01-01

    We analyze the theoretical and phenomenological considerations for the electroweak phase transition and dark matter in an extension of the standard model with a complex scalar singlet (cxSM). In contrast with earlier studies, we use a renormalization group improved scalar potential and treat its thermal history in a gauge-invariant manner. We find that the parameter space consistent with a strong first-order electroweak phase transition (SFOEWPT) and present dark matter phenomenological constraints is significantly restricted compared to results of a conventional, gauge-noninvariant analysis. In the simplest variant of the cxSM, recent LUX data and a SFOEWPT require a dark matter mass close to half the mass of the standard model-like Higgs boson. We also comment on various caveats regarding the perturbative treatment of the phase transition dynamics.

    In recent years, surface wave seismology has become one of the leading directions in seismological investigations of the Earth's structure and seismic sources. Various applications cover a wide spectrum of goals, dealing with differences in sources of seismic excitation, penetration depths, frequency ranges, and interpretation techniques. Observed seismic data demonstrates the great variability of phenomenology which can produce difficulties in interpretation for beginners. This tutorial review is based on the many years' experience of authors in processing and interpretation of seismic surface wave observations and the lectures of one of the authors (ALL) at Workshops on Seismic Wave Excitation, Propagation and Interpretation held at the Abdus Salam International Center for Theoretical Physics (Trieste, Italy) in 1990-2012. We present some typical examples of wave patterns which could be encountered in different applications and which can serve as a guide to analysis of observed seismograms.

    2018-02-01

    We investigate the phenomenology of a simplified model of flavoured Dark Matter (DM), with a dark fermionic flavour triplet coupling to the left-handed SU(2) L quark doublets via a scalar mediator. The DM-quark coupling matrix is assumed to constitute the only new source of flavour and CP violation, following the hypothesis of Dark Minimal Flavour Violation. We analyse the constraints from LHC searches, from meson mixing data in the K, D, and B d,s meson systems, from thermal DM freeze-out, and from direct detection experiments. Our combined analysis shows that while the experimental constraints are similar to the DMFV models with DM coupling to right-handed quarks, the multitude of couplings between DM and the SM quark sector resulting from the SU(2) L structure implies a richer phenomenology and significantly alters the resulting impact on the viable parameter space.
