Phenomenological Approaches in Psychology and Health Sciences  

PubMed Central

A whole family of qualitative methods is informed by phenomenological philosophy. When applying these methods, the material is analyzed using concepts from this philosophy to interrogate the findings and to enable greater theoretical analysis. However, the phenomenological approach represents different approaches, from pure description to those more informed by interpretation. Phenomenological philosophy developed from a discipline focusing on thorough descriptions, and only descriptions, toward a greater emphasis on interpretation being inherent in experience. An analogous development toward a broader acknowledgment of the need for interpretation, the influence of the relationship and the researcher, and the co-construction of the narrative is mirrored in qualitative analytic theory and the description of newer analytic methods as, for example, Interpretative Phenomenological Analysis and Critical Narrative Analysis, methods which are theoretically founded in phenomenology. This methodological development and the inevitable contribution of interpretation are illustrated by a case from my own research about psychological interventions and the process of understanding in general practice.

Factors influencing the development and implementation of advanced radiographer practice in Australia - a qualitative study using an interpretative phenomenological approach  

PubMed Central

Introduction The purpose of this study was to explore the factors influencing the implementation or the lack of implementation of advanced practitioner role in Australia. Methods This study uses an interpretative phenomenological approach to explore the in-depth real life issues, which surround the advanced practitioner as a solution to radiologist workforce shortages in Australia. Research participants are radiographers, radiation therapists and health managers registered with the Australian Institute of Radiography (AIR) and holding senior professional and AIR Board positions with knowledge of current advanced practice. Results In total, seven interviews were conducted revealing education, governance, technical, people issues, change management, government, costs and timing as critical factors influencing advanced practice in Australia. Conclusions Seven participants in this study perceived an advanced practice role might have major benefits and a positive impact on the immediate and long-term management of patients. Another finding is the greater respect and appreciation of each other's roles and expertise within the multidisciplinary healthcare team. Engagement is required of the critical stakeholders that have been identified as ‘blockers’ (radiologists, health departments) as well as identified allies (e.g. emergency clinicians, supportive radiologists, patient advocacy groups). The research supports that the AIR has a role to play for the professional identity of radiographers and shaping the advanced practice role in Australia.

An integrated approach to determine phenomenological equations in metallic systems  

NASA Astrophysics Data System (ADS)

It is highly desirable to be able to make predictions of properties in metallic materials based upon the composition of the material and the microstructure. Unfortunately, the complexity of real, multi-component, multi-phase engineering alloys makes the provision of constituent-based (i.e., composition or microstructure) phenomenological equations extremely difficult. Due to these difficulties, qualitative predictions are frequently used to study the influence of microstructure or composition on the properties. Neural networks were used as a tool to get a quantitative model from a database. However, the developed model is not a phenomenological model. In this study, a new method based upon the integration of three separate modeling approaches, specifically artificial neural networks, genetic algorithms, and monte carlo was proposed. These three methods, when coupled in the manner described in this study, allows for the extraction of phenomenological equations with a concurrent analysis of uncertainty. This approach has been applied to a multi-component, multi-phase microstructure exhibiting phases with varying spatial and morphological distributions. Specifically, this approach has been applied to derive a phenomenological equation for the prediction of yield strength in alpha+beta processed Ti-6-4. The equation is consistent with not only the current dataset but also, where available, the limited information regarding certain parameters such as intrinsic yield strength of pure hexagonal close-packed alpha titanium.

An Algorithmic Approach to Heterotic String Phenomenology  

E-print Network

We briefly review the recent programme to construct, systematically and algorithmically, large classes of heterotic vacua, as well as the search for the MSSM therein. Specifically, we outline the monad construction of vector bundles over complete intersection Calabi-Yau threefolds, their classification, stability, equivariant cohomology and subsequent relevance to string phenomenology. It is hoped that this top-down algorithmic approach will isolate special corners in the heterotic landscape.

Hearing voices: A phenomenological-hermeneutic approach.  


The word "phenomenology" has a number of meanings. In this paper we briefly contrast the different meanings of the word in psychiatry and philosophy. We then consider the work of the philosophers Heidegger and Merleau-Ponty, as examples of what Hubert Dreyfus calls ontological phenomenology, in contrast to an epistemological approach. We present a brief outline of Merleau-Ponty's theory of embodiment, and contrast this with the dominant, epistemological (or Cartesian) view of experience. Through the example of a woman who experienced bereavement hallucinations, we try to show how this approach can open up a hermeneutic approach to the experience of hearing voices. An understanding of embodiment can help to counter reductionism, whether biological or social, and dualism (body/mind and mind/society). It is only when we consider the totality of human experience that we can understand its meaning. This has two main benefits. First, it legitimates the claims made by those who hear voices that their experiences are intrinsically meaningful. Second, it can provide a framework for those who work with voice hearers and who are interested in understanding these experiences. In this sense, phenomenology can become a valuable clinical tool.

Phenomenological approach to eukaryotic chemotactic efficiency  

PubMed Central

Eukaryotic cells are capable of detecting small chemical gradients for a wide range of background concentrations. Ultimately, fluctuations place a limit on gradient sensing and recent work has focused on the role of stochastic receptor occupancy as one possible limiting factor. Here, we use a phenomenological approach to add spontaneous motility fluctuations to receptor noise and predict the directional statistics of eukaryotic chemotaxis. Specifically, an Itô diffusion equation with direction-dependent multiplicative noise is developed and analytically studied. We show that our approach can naturally accommodate recent experimental data for the chemotaxis of the social amoeba Dictyostelium. PMID:20365769

[An existential-phenomenological approach to consciousness].  


The human beings are characterized as subjects. Their essence is understood as Person. A treatment which does not consider the subjective and the Person would not correspond their essence. For a feeling and autonomous being, consciousness plays a role but cannot fully correspond the being a person. This has a therapeutic impact on the treatment of unconscious patients and gives the treatment a specific access. Some instructions for the therapeutic application of the phenomenological-existential concept and the phenomenological attitude towards unconscious or brain traumatized patients are given. The role of consciousness for being human is briefly reflected from an existential perspective. PMID:24761600

Making sense of denial in sexual offenders: a qualitative phenomenological and repertory grid analysis.  


Denial in sexual offenders represents the first barrier to successful treatment a clinician is likely to face. Most sex offender treatment programs devote significant time to overcoming denial, with most programs having a focus on disclosure and "accepting responsibility." This is the first study that has aimed to make sense of sexual offenders' denial through a rigorous qualitative analysis. The main objective was to explore the experiences and lived worlds of sexual offenders in denial. A qualitative phenomenological methodology combining interpretative phenomenological analysis and repertory grids was implemented. Ten incarcerated sexual offenders in categorical denial participated in the research. The analysis revealed the narrative, relational, and self-reconstructive properties of denial and discusses the role and function denial may be playing for sexual offenders. The results highlight that denial can be viewed as a form of "sense making" and that clinically relevant treatment targets can be elicited without disclosure. It is concluded that viewing denial as a barrier to treatment impedes constructive work with offenders, and implications for treatment are discussed. PMID:24442912

Dark matter profiles in clusters of galaxies: a phenomenological approach  

NASA Astrophysics Data System (ADS)

There are some basic differences between the observed properties of galaxies and clusters and the predictions from current hydrodynamical simulations. These are particularly pronounced in the central regions of galaxies and clusters. The popular NFW (Navarro, Frenk and White) profile, for example, predicts a density cusp at the center, a behavior that (unsurprisingly) has not been observed. While it is not fully clear what are the reasons for this discrepancy, it perhaps reflects (at least partly) insufficient spatial resolution of the simulations. In this paper we explore a purely phenomenological approach to determine dark matter density profiles that are more consistent with observational results. Specifically, we deduce the gas density distribution from measured X-ray brightness profiles, and substitute it in the hydrostatic equilibrium equation in order to derive the form of dark matter profiles. Given some basic theoretical requirements from a dark matter profile, we then consider a number of simple profiles that have the desired asymptotic form. We conclude that a dark matter profile of the form ?=? 01+r/r a-3 is most consistent with current observational results.

Towards a new approach to quantum gravity phenomenology  

E-print Network

The idea that quantum gravity manifestations would be associated with a violation of Lorentz invariance is very strongly bounded and faces serious theoretical challenges. This leads us to consider an alternative line of thought for such phenomenological search. We discuss the underlying viewpoint and briefly mention its possible connections with current theoretical ideas. We also outline the challenges that the experimental search of the effects would seem to entail.

Phenomenology and neurophysiological correlations: two approaches to perception research.  


This article argues that phenomenological description and neurophysiological correlation complement each other in perception research. Whilst phenomena constitute the material, neuronal mechanisms are indispensable for their explanation. Numerous examples of neurophysiological correlates show that the correlation of phenomenology and neurophysiology is fruitful. Phenomena for which neuronal mechanism have been found include: (in area V1) filling-in of real and artificial scotomata, contour integration, figure-ground segregation by orientation contrast, amodal completion, and motion transparency; (in V2) modal completion, border ownership, surface transparency, and cyclopean perception; (in V3) alignment in dotted contours, and filling-in with dynamic texture; (in V4) colour constancy; (in MT) shape by accretion/deletion, grouping by coherent motion, apparent motion in motion quartets, motion in apertures, and biological motion. Results suggest that in monkey visual cortex, occlusion cues, including stereo depth, are predominantly processed in lower areas, whereas mechanisms for grouping and motion are primarily represented in higher areas. More correlations are likely to emerge as neuroscientists strive for a better understanding of visual perception. The paper concludes with a review of major achievements in visual neuroscience pertinent to the study of the phenomena under consideration. PMID:19303897

Dosimetry of Auger emitters: Physical and phenomenological approaches  

SciTech Connect

Recent radiobiological studies have demonstrated that Auger cascades can cause severe biological damage contrary to expectations based on conventional dosimetry. Several determinants govern these effects, including the nature of the Auger electron spectrum; localized energy deposition; cellular geometry; chemical form of the carrier; cellular localization, concentration, and subcellular distribution of the radionuclide. Conventional dosimetry is inadequate in that these considerations are ignored. Our results provide the basis for biophysical approaches toward subcellular dosimetry of Auger emitters in vitro and in vivo. 12 refs., 7 figs., 2 tabs.

A phenomenological approach to multisource data integration: Analysing infrared and visible data  

NASA Technical Reports Server (NTRS)

A new method is described for combining multisensory data for remote sensing applications. The approach uses phenomenological models which allow the specification of discriminatory features that are based on intrinsic physical properties of imaged surfaces. Thermal and visual images of scenes are analyzed to estimate surface heat fluxes. Such analysis makes available a discriminatory feature that is closely related to the thermal capacitance of the imaged objects. This feature provides a method for labelling image regions based on physical properties of imaged objects. This approach is different from existing approaches which use the signal intensities in each channel (or an arbitrary linear or nonlinear combination of signal intensities) as features - which are then classified by a statistical or evident approach.

Difficulties and coping strategies of Sudanese refugees: a qualitative approach.  


A qualitative approach was used to interview 23 Sudanese refugees residing in Brisbane, Australia. Semi-structured interviews were conducted to examine the participants' pre-migration, transit and post-migration experiences. Refugees reported traumatic and life-threatening experiences during the pre-migration and transit phases, and difficulties with resettlement during the post-migration phase. Nevertheless, participants reported using a number of coping strategies across all phases, including: reliance on religious beliefs, cognitive strategies such as reframing the situation, relying on their inner resources, and focusing on future wishes and aspirations. Social support also emerged as a salient coping strategy. The findings are useful for mental health professionals as they highlight the difficulties experienced by refugees across phases of migration as well as strategies they use to manage these traumas and stresses.

Investigating Reasons for CPAP Adherence in Adolescents: A Qualitative Approach  

PubMed Central

Study Objectives: Adolescents with obstructive sleep apnea syndrome (OSAS) represent an important but understudied subgroup of long-term continuous positive airway pressure (CPAP) users. The purpose of this qualitative study was to identify factors related to adherence from the perspective of adolescents and their caregivers. Methods: Individual open-ended, semi-structured interviews were conducted with adolescents (n = 21) and caregivers (n = 20). Objective adherence data from the adolescents' CPAP machines during the previous month was obtained. Adolescents with different adherence levels and their caregivers were asked their views on CPAP. Using a modified grounded theory approach, we identified themes and developed theories that explained the adolescents' adherence patterns. Results: Adolescent participants (n = 21) were aged 12-18 years, predominantly male (n = 15), African American (n = 16), users of CPAP for at least one month. Caregivers were mainly mothers (n = 17). Seven adolescents had high use (mean use 381 ± 80 min per night), 7 had low use (mean use 30 ± 24 min per night), and 7 had no use during the month prior to being interviewed. Degree of structure in the home, social reactions, mode of communication among family members, and perception of benefits were issues that played a role in CPAP adherence. Conclusions: Understanding the adolescent and family experience of using CPAP may be key to increasing adolescent CPAP adherence. As a result of our findings, we speculate that health education, peer support groups, and developmentally appropriate individualized support strategies may be important in promoting adherence. Future studies should examine these theories of CPAP adherence. Citation: Prashad PS; Marcus CL; Maggs J; Stettler N; Cornaglia MA; Costa P; Puzino K; Xanthopoulos M; Bradford R; Barg FK.

A phenomenological approach to normal form modeling: a case study in laser induced nematodynamics  

E-print Network

An experimental setting for the polarimetric study of optically induced dynamical behavior in nematic liquid crystal films has allowed to identify most notably some behavior which was recognized as gluing bifurcations leading to chaos. This analysis of the data used a comparison with a model for the transition to chaos via gluing bifurcations in optically excited nematic liquid crystals previously proposed by G. Demeter and L. Kramer. The model of these last authors, proposed about twenty years before, does not have the central symmetry which one would expect for minimal dimensional models for chaos in nematics in view of the time series. What we show here is that the simplest truncated normal forms for gluing, with the appropriate symmetry and minimal dimension, do exhibit time signals that are embarrassingly similar to the ones found using the above mentioned experimental settings. The gluing bifurcation scenario itself is only visible in limited parameter ranges and substantial aspect of the chaos that can be observed is due to other factors. First, out of the immediate neighborhood of the homoclinic curve, nonlinearity can produce expansion leading to chaos when combined with the recurrence induced by the homoclinic behavior. Also, pairs of symmetric homoclinic orbits create extreme sensitivity to noise, so that when the noiseless approach contains a rich behavior, minute noise can transform the complex damping into sustained chaos. Leonid Shil'nikov taught us that combining global considerations and local spectral analysis near critical points is crucial to understand the phenomenology associated to homoclinic bifurcations. Here this helps us construct a phenomenological approach to modeling experiments in nonlinear dissipative contexts.

Restrictions on Measurement of Roughness of Textile Fabrics by Laser Triangulation: A Phenomenological Approach  

SciTech Connect

Laser triangulation method is one of the methods used for contactless measurement of roughness of textile fabrics. Method is based on measurement of distance between the sensor and the object by imaging the light scattered from the surface. However, experimental results, especially for high values of roughness, show a strong dependence to duration of exposure time to laser pulses. Use of very short exposure times and long exposures times causes appearance on the surface of the scanned textile of pixels with Active peak heights. The number of Active peaks increases with decrease of exposure time down to 0.1 ms, and increases with increase of exposure time up to 100 ms. Appearance of Active peaks leads to nonrealistic increase of roughness of the surface both for short exposure times and long exposure times reaching a minimum somewhere in the region of medium exposure times, 1 to 2 ms. The above effect suggests a careful analysis of experimental data and, also, becomes an important restriction to the method. In this paper we attempt to make a phenomenological approach to the mechanisms leading to these effects. We suppose that effect is related both to scattering properties of scanned surface and to physical parameters of CCD sensors. The first factor becomes more important in the region of long exposure times, while second factor becomes more important in the region of short exposure times.

Nurses' experiences of recruitment and migration from developing countries: a phenomenological approach  

PubMed Central

Background There is growing concern globally at the current flows of nurse migration, particularly from low-income to middle and high-income countries. Recruitment practices of many countries such as Ireland are thought to be fuelling this rate of migration. This paper aims to establish the perceptions and opinions of those involved in the recruitment process on their role in recruitment and the effects recruitment has on both source and destination countries. Methods A purposive sample of 12 directors of nursing, from major academic teaching hospitals in Dublin and hospitals in South Africa and the Philippines were recruited. Ten overseas nurses were also recruited. A phenomenological approach was used with semi-structured interviews as the data collection method. Results There were pronounced differences in opinions between the Irish and the overseas directors on recruitment and its effects on the health systems of the source countries. Difficulties in the retention of staff were highlighted by both groups of directors. Other findings included the language and cultural differences experienced by the overseas nurses. Conclusion Recruitment of overseas nurses should not be left to the individual employer even in the presence of government guidelines. An international effort from all the involved parties is required to formulate a solution to this complex issue in order to protect both the health systems of individual countries and the nurse's right to migrate.

A Syntactical Approach to Qualitative Constraint Networks Merging  

NASA Astrophysics Data System (ADS)

We address the problem of merging qualitative constraint networks (QCNs) representing agents local preferences or beliefs on the relative position of spatial or temporal entities. Two classes of merging operators which, given a set of input QCNs defined on the same qualitative formalism, return a set of qualitative configurations representing a global view of these QCNs, are pointed out. These operators are based on local distances and aggregation functions. In contrast to QCN merging operators recently proposed in the literature, they take account for each constraint from the input QCNs within the merging process. Doing so, inconsistent QCNs do not need to be discarded at start, hence agents reporting locally consistent, yet globally inconsistent pieces of information (due to limited rationality) can be taken into consideration.

A Computational Approach to Qualitative Analysis in Large Textual Datasets

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

Teaching electric circuits with multiple batteries: A qualitative approach  

NSDL National Science Digital Library

We have investigated preservice science teachersâ qualitative understanding of circuits consisting of multiple batteries in single and multiple loops using a pretest and post-test method and classroom observations. We found that most students were unable to explain the effects of adding batteries in single and multiple loops, as they tended to use reasoning based on current and resistance where reasoning based on voltage is a necessity. We also found that problems such as thinking of the battery as a source of constant current resurfaced in this new context, and that answers given were inconsistent with current conservation. We describe the curriculum we developed that enables students to model circuits with multiple batteries qualitatively. Post-test results show that the majority of students were able to apply their newly developed model to make accurate predictions for complex circuits.

Measuring customer perceptions of emergency facility services: a qualitative approach.  


The purpose of this study was to use a qualitative research technique and define problems faced by one hospital that was attempting to increase demand for its emergency services. A telephone survey of 450 affluent and well-educated suburban residents was conducted to determine their perceptions of six major facilities. Topics included actual and preferred facility use by injury type, general perceptions concerning staff and facility, and other components of service quality. Results indicated that a variety of sociological, psychological, environmental, and situational factors interacted when the respondents formed attitudes concerning hospital emergency use and service. They were often uncertain of their real attitudes and conveyed varying opinions about the desirability or effectiveness of similar services. Health care providers should note these differences and modify the marketing mixes in a manner that best conveys their unit's competitive advantages. They could also benefit from using the qualitative research technique described in this paper and from adopting the marketing concept. PMID:10122743

A Phenomenological Lagrangian Approach to Two Kaon Photoproduction and Pentaquark Searches  

E-print Network

We examine cross sections for the processes $\\gamma N\\to NK\\bar{K}$ in the framework of a phenomenological Lagrangian. We include contributions from $\\Lambda$ and $\\Sigma$ resonances up to spin 3/2, as well as those from an exotic $\\Theta^+$. We allow the $\\Theta^+$ to have spin 1/2 or 3/2, with either positive or negative parity in each case. We also allow the state to be either isovector or isoscalar. We find that the scenario that most closely matches observations at Jefferson Laboratory requires a moderately large coupling of the $\\Theta^+$ to $NK^*$.

A Qualitative Approach to Mobile Robot Navigation Using RFID  

NASA Astrophysics Data System (ADS)

Radio Frequency Identification (RFID) system allows automatic identification of items with RFID tags using radio-waves. As the RFID tag has its unique identification number, it is also possible to detect a specific region where the RFID tag lies in. Recently it is widely been used in mobile robot navigation, localization, and mapping both in indoor and outdoor environment. This paper represents a navigation strategy for autonomous mobile robot using passive RFID system. Conventional approaches, such as landmark or dead-reckoning with excessive number of sensors, have complexities in establishing the navigation and localization process. The proposed method satisfies less complexity in navigation strategy as well as estimation of not only the position but also the orientation of the autonomous robot. In this research, polar coordinate system is adopted on the navigation surface where RFID tags are places in a grid with constant displacements. This paper also presents the performance comparisons among various grid architectures through simulation to establish a better solution of the navigation system. In addition, some stationary obstacles are introduced in the navigation environment to satisfy the viability of the navigation process of the autonomous mobile robot.

Psychosocial aspects of Taiwanese postpartum depression phenomenological approach: a preliminary report.  


To understand how Taiwanese women experience postpartum depression, a phenomenological study was conducted. A purposive sample of six mothers participated in the present study. All the subjects' interviews were tape recorded and then transcribed. The transcription of each subject's oral description of postpartum depression experience was analyzed using Colaizzi's phenomenological methodology. Three categories, with ten themes, were derived from the analysis. The first category is unbalanced role-enacting. It includes these four themes: (1) the discrepancies in the husband-wife relationship; (2) the shadowy position of a daughter-in-law; (3) the incompetence as a mother; and (4) the dilemma of a woman's identity. The second category is fragmented time-space representation. The themes included are: (5) cultural bondage; (6) loss of ideals; and (7) reinterpretation of family history. The third category is the uneasy self. It contains the themes of: (8) psychological disability; (9) sense of self-dissatisfaction; and (10) the notion or behavior of destruction. PMID:10063795

The ethics of neuroscience and the neuroscience of ethics: a phenomenological-existential approach.  


Advances in the neurosciences have many implications for a collective understanding of what it means to be human, in particular, notions of the self, the concept of volition or agency, questions of individual responsibility, and the phenomenology of consciousness. As the ability to peer directly into the brain is scientifically honed, and conscious states can be correlated with patterns of neural processing, an easy--but premature--leap is to postulate a one-way, brain-based determinism. That leap is problematic, however, and emerging findings in neuroscience can even be seen as compatible with some of the basic tenets of existentialism. Given the compelling authority of modern "science," it is especially important to question how the findings of neuroscience are framed, and how the articulation of research results challenge or change individuals' perceptions of themselves. Context plays an essential role in the emergence of human identity and in the sculpting of the human brain; for example, even a lack of stimuli ("nothing") can lead to substantial consequences for brain, behavior, and experience. Conversely, advances in understanding the brain might contribute to more precise definitions of what it means to be human, including definitions of appropriate social and moral behavior. Put another way, the issue is not simply the ethics involved in framing neurotechnology, but also the incorporation of neuroscientific findings into a richer understanding of human ethical (and existential) functioning.

Qualitative Approach to Attempted Suicide by Adolescents and Young Adults: The (Neglected) Role of Revenge  

PubMed Central

Background Suicide by adolescents and young adults is a major public health concern, and repetition of self-harm is an important risk factor for future suicide attempts. Objective Our purpose is to explore the perspective of adolescents directly involved in suicidal acts. Methods Qualitative study involving 16 purposively selected adolescents (sex ratio1?1) from 3 different centers. Half had been involved in repeated suicidal acts, and the other half only one. Data were gathered through semistructured interviews and analyzed according to Interpretative Phenomenological Analysis. Results We found five main themes, organized in two superordinate themes. The first theme (individual dimensions of the suicide attempt) describes the issues and explanations that the adolescents saw as related to themselves; it includes the subthemes: (1) negative emotions toward the self and individual impasse, and (2) the need for some control over their lives. The second main theme (relational dimensions of attempted suicide) describes issues that adolescents mentioned that were related to others and includes three subthemes: (3) perceived impasse in interpersonal relationships, (4) communication, and (5) revenge. Conclusions Adolescents involved in suicidal behavior are stuck in both an individual and a relational impasse from which there is no exit and no apparent way to reach the other. Revenge can bridge this gap and thus transforms personal distress into a relational matter. This powerful emotion has been neglected by both clinicians and researchers. PMID:24802777

Supersymmetry Phenomenology  

E-print Network

This is a very pedagogical review of supersymmetry phenomenology, given at ICTP Summer School in 1999, aimed mostly at students who had never studied supersymmetry before. It starts with an analogy that the reason why supersymmetry is needed is similar to the reason why the positron exists. It introduces the construction of supersymmetric Lagrangians in a practical way. The low-energy constraints, renormalization-group analyses, collider phenomenology, and frameworks of mediating supersymmetry breaking are briefly discussed.

Toward a phenomenological approach to the clustering of heavy particles in turbulent flows  

E-print Network

A simple model accounting for the ejection of heavy particles from the vortical structures of a turbulent flow is introduced. This model involves a space and time discretization of the dynamics and depends on only two parameters: the fraction of space-time occupied by rotating structures of the carrier flow and the rate at which particles are ejected from them. The latter can be heuristically related to the response time of the particles and hence measure their inertia. It is shown that such a model reproduces qualitatively most aspects of the spatial distribution of heavy particles transported by realistic flows. In particular the probability density function of the mass $m$ in a cell displays an power-law behavior at small values and decreases faster than exponentially at large values. The dependence of the exponent of the first tail upon the parameters of the dynamics is explicitly derived for the model. The right tail is shown to decrease as $\\exp (-C m \\log m)$. Finally, the distribution of mass averaged over several cells is shown to obey rescaling properties as a function of the coarse-grain size and of the ejection rate of the particles. Contrarily to what has been observed in direct numerical simulations of turbulent flows (Bec et al.,, such rescaling properties are only due in the model to the mass dynamics of the particles and do not involve any scaling properties in the spatial structure of the carrier flow.

Review of Qualitative Approaches for the Construction Industry: Designing a Risk Management Toolbox  

PubMed Central

Objectives This paper presents the framework and protocol design for a construction industry risk management toolbox. The construction industry needs a comprehensive, systematic approach to assess and control occupational risks. These risks span several professional health and safety disciplines, emphasized by multiple international occupational research agenda projects including: falls, electrocution, noise, silica, welding fumes, and musculoskeletal disorders. Yet, the International Social Security Association says, "whereas progress has been made in safety and health, the construction industry is still a high risk sector." Methods Small- and medium-sized enterprises (SMEs) employ about 80% of the world's construction workers. In recent years a strategy for qualitative occupational risk management, known as Control Banding (CB) has gained international attention as a simplified approach for reducing work-related risks. CB groups hazards into stratified risk 'bands', identifying commensurate controls to reduce the level of risk and promote worker health and safety. We review these qualitative solutions-based approaches and identify strengths and weaknesses toward designing a simplified CB 'toolbox' approach for use by SMEs in construction trades. Results This toolbox design proposal includes international input on multidisciplinary approaches for performing a qualitative risk assessment determining a risk 'band' for a given project. Risk bands are used to identify the appropriate level of training to oversee construction work, leading to commensurate and appropriate control methods to perform the work safely. Conclusion The Construction Toolbox presents a review-generated format to harness multiple solutions-based national programs and publications for controlling construction-related risks with simplified approaches across the occupational safety, health and hygiene professions.

Phenomenological study of the $B_{c}$ ${\\to}$ $BP$, $BV$ decays with perturbative QCD approach

Inspired by the recent LHCb measurements and forthcoming great potential on $B_{c}$ meson, we study the exclusive $B_{c}$ ${\\to}$ $B_{q}P$, $B_{q}V$ decays with the perturbative QCD approach, where $q$ $=$ $u$, $d$, $s$; $P$ and $V$ denote the lightest pseudoscalar and vector $SU(3)$ nonet meson, respectively. By retaining the quark transverse momentum, employing the Sudakov factors, and choosing the typical scale as the maximum virtualities of the internal particles, we calculate the $B_{c}$ ${\\to}$ $B$ transition from factors, and our results show that about 90\\% contribution to form factors come from the ${\\alpha}_{s}/{\\pi}$ $<$ $0.3$ region. The contributions of penguin and annihilation to branching ratios are very small due to the serious suppression by the CKM factors. There is some hierarchy relations among the $B_{c}$ ${\\to}$ $BP$, $BV$ decays. The branching ratios for $B_{c}$ ${\\to}$ $B_{d,s}{\\pi}$, $B_{d,s}{\\rho}$, $B_{s}K$ are large and could be measured by the running LHCb.

Foot orthoses for the management of low back pain: a qualitative approach capturing the patient's perspective  

PubMed Central

Background The onset of non specific low back pain is associated with heavy lifting, age, female gender, and poor general health, with psychological factors being predictors of it becoming chronic. Additionally, it is thought that altered lower limb biomechanics are a contributory factor, with foot orthoses increasingly being considered as an appropriate intervention by physiotherapists and podiatrists. However, research into the effect of foot orthoses is inconclusive, primarily focusing on the biomechanical effect and not the symptomatic relief from the patient’s perspective. The aim of this study was to explore the breadth of patients’ experiences of being provided with foot orthoses and to evaluate any changes in their back pain following this experience. Method Following ethical approval, participants (n?=?25) with non-specific low back pain associated with altered lower limb biomechanics were provided with customised foot orthoses. At 16 weeks after being provided with the foot orthoses, conversational style interviews were carried out with each patient. An interpretivistic phenomenological approach was adopted for the data collection and analysis. Results For these participants, foot orthoses appeared to be effective. However, the main influence on this outcome was the consultation process and a patient focussed approach. The consultation was an opportunity for fostering mutual understanding, with verbal and visual explanation reassuring the patient and this influenced the patient’s beliefs, their engagement with the foot orthoses (physical) and their experience of low back pain (psychological). Conclusion Clinicians need to adopt ‘psychologically informed practice’ in relation to the provision of foot orthoses. Likewise, researchers should consider all the influencing factors found in this study, both in relation to their study protocol and the outcomes they plan to measure. PMID:23651579



Clients' experiences of the Boston Psychiatric Rehabilitation Approach: a qualitative study.  


The Boston Psychiatric Rehabilitation Approach (BPR) is person-centered and characterized by being based entirely on the individual's unique needs and preferences in the areas of working, learning, social contacts, and living environment. Nevertheless, the person-centered approach is lacking firm evidence regarding outcomes, and empirical studies regarding clients' experiences of this particular model are needed. A qualitative content analysis of 10 transcribed semistructured individual interviews was used to describe and explore clients' experiences of the BPR during an implementation project in Sweden. The findings from the interviews could be summarized in "A sense of being in communion with self and others" theme, consisting of three categories: increased self-understanding, getting new perspectives, and being in a trusting relationship. The results showed that clients do not always recognize nor are able to verbalize their goals before they have been given the possibility to reflect their thoughts in collaboration with a trusted person. The guidelines of the approach are intended to support the clients' ability to participate in decision making regarding their own care. More research about efficacy of different rehabilitation approaches and exploration of fidelity to guidelines of rehabilitation programs are required. PMID:24717265

A Phenomenological, Evaluative Approach to Developing Ecology Virtual Field Trips for Undergraduate, Non-Major College Students  

NASA Astrophysics Data System (ADS)

Field trips are an important source of support for the ecology curriculum. Virtual field trips (VFTs) may provide a similar experience, but limited research existed on the specific format of a VFT that would support its use to replace the actual ecology field trip (PFT). In attempting to delineate potential design considerations for the VFT, this study employed a phenomenological approach to elicit participant input on design considerations for the ecology VFT. The study focused on narration, text, still and video images, and instructor participation in the VFT. Undergraduate, non-major biology students comprised the study population. Two surveys instruments were used to gather information on VFT design from participants: an initial attitudinal survey and an expanded survey. The initial participant group of 30 individuals viewed ecology VFTs designed for the study and completed the initial survey, after which a focus group was formed to complete the expanded survey. Using information contained in the surveys, 18 unique themes were then developed from the perspectives and narratives provided by participants. Initial themes that emerged during analysis suggested that the VFT be instructor designed and that the instructor should actively participate in the VFT media. It was found that having the instructor participate in the VFT, both in the design and in the media presentation itself, was considered essential by the students. Participant developed themes suggested emphasizing the perceived strengths of the individual media components by combining media components to increases the effectiveness of the VFT and remediate individual component weaknesses. Each individual component was seen to provide a specific cognitive function within the VFT and all were seen as necessary to include in the VFT. However, the studied components increased the effectiveness of the VFT only if used with reference to those specific design considerations suggested by participant input. The results of this study found that incorporating these themes into ecology VFTs would increase the effectiveness of this teaching modality. Future inquiry should be directed toward defining those instructor attributes that are essential to their successful participation in the VFT and researching potential expansion of this model to other subject areas.

Relatives' experiences of the Boston Psychiatric Rehabilitation approach: a qualitative study.  


The Boston Psychiatric Rehabilitation (BPR) approach is individualized and characterized by being based entirely on the individual's unique needs and preferences in the areas of working, learning, social contacts, and living environment. Relatives of clients in mental health services influence the client's possibilities for recovery by their everyday relationship. Relatives have, however, traditionally had a subordinated role in the care of their mentally ill family member. The perspective of relatives is an important aspect in the development of new approaches to psychiatric rehabilitation. The purpose of this study was thus to describe and explore relatives' experiences of the BPR approach. Ten relatives of clients in mental health services taking part in the BPR were interviewed. The interviews were transcribed and analyzed with a qualitative content analysis method to explore relatives' experiences of the BPR intervention in a county in Sweden. The findings from the interviews could be summarized in the theme "To meet the clients' needs" consisting of three categories: "Dependence on staffs' competence," "Responsibility for user involvement," and "The necessity for coordination between authorities and caregivers." The findings suggest that relatives may contribute with important information about clients' needs related to outcome of care. Relatives' perspectives may be of importance in future development of BPR. Further research about the relatives' role in psychiatric rehabilitation is needed as well as studies that compare different kinds of psychiatric rehabilitation from the perspective of relatives.

Modeling approaches for qualitative and semi-quantitative analysis of cellular signaling networks  

PubMed Central

A central goal of systems biology is the construction of predictive models of bio-molecular networks. Cellular networks of moderate size have been modeled successfully in a quantitative way based on differential equations. However, in large-scale networks, knowledge of mechanistic details and kinetic parameters is often too limited to allow for the set-up of predictive quantitative models. Here, we review methodologies for qualitative and semi-quantitative modeling of cellular signal transduction networks. In particular, we focus on three different but related formalisms facilitating modeling of signaling processes with different levels of detail: interaction graphs, logical/Boolean networks, and logic-based ordinary differential equations (ODEs). Albeit the simplest models possible, interaction graphs allow the identification of important network properties such as signaling paths, feedback loops, or global interdependencies. Logical or Boolean models can be derived from interaction graphs by constraining the logical combination of edges. Logical models can be used to study the basic input–output behavior of the system under investigation and to analyze its qualitative dynamic properties by discrete simulations. They also provide a suitable framework to identify proper intervention strategies enforcing or repressing certain behaviors. Finally, as a third formalism, Boolean networks can be transformed into logic-based ODEs enabling studies on essential quantitative and dynamic features of a signaling network, where time and states are continuous. We describe and illustrate key methods and applications of the different modeling formalisms and discuss their relationships. In particular, as one important aspect for model reuse, we will show how these three modeling approaches can be combined to a modeling pipeline (or model hierarchy) allowing one to start with the simplest representation of a signaling network (interaction graph), which can later be refined to logical and eventually to logic-based ODE models. Importantly, systems and network properties determined in the rougher representation are conserved during these transformations. PMID:23803171



String Phenomenology  

E-print Network

Following Dyson's analogy between the quantum field theory and the 19th-century chemistry-both explain how but not why-one could also establish an analogy between atomic physics and string theory. Atomic physics was needed to answer the question why in chemistry, string theory is trying to answer the question why in the standard model. This attempt is very briefly reviewed in this talk. After discussing the phenomenological aspects of string theory, the study of soft terms is emphasized as a possible connection between theory and experiment. Special attention is paid to the issues of flavor changing neutral currents, loop effects, charge and color breaking minima, and M-theory versus weakly coupled string theory.

Phenomenological models  

SciTech Connect

The biological effects of ionizing radiation exposure are the result of a complex sequence of physical, chemical, biochemical, and physiological interactions. One way to begin a search for an understanding of health effects of radiation is through the development of phenomenological models of the response. Many models have been presented and tested in the slowly evolving process of characterizing cellular response. A range of models covering different endpoints and phenomena has developed in parallel. Many of these models employ similar assumptions about some underlying processes while differing about the nature of others. An attempt is made to organize many of the models into groups with similar features and to compare the consequences of those features with the actual experimental observations. It is assumed that by showing that some assumptions are inconsistent with experimental observations, the job of devising and testing mechanistic models can be simplified. 43 refs., 13 figs.

Decoding the integrated approach to yoga therapy: Qualitative evidence based conceptual framework  

PubMed Central

Aim: The aim of this study was to define, decode, and append to the conceptual frame-work of the integrated approach to yoga therapy (IAYT). Materials and Methods: Four stakeholders who followed two in-patients with depression over a period of 2 weeks in the residential center Arogyadhama (of Swami Vivekananda Yoga Anusandana Samsthana, Bangalore, India) were interviewed before the start of the IAYT treatment and prior to discharge of the patient. The patients were also interviewed pre and post and were observed once during their session. The data from the audio recordings from eight in-depth interviews were transcribed manually and qualitative analysis was conducted. Results: The conceptual frame-work of IAYT depicts that patient related factors (“co-operation of patient”, “patients awareness of his/her condition”), therapist related factors (“ability to guide”, “the assistance to the patients”, “explanation of the exercises”) and treatment related factors (“combination of psychiatric or Ayurvedic medication with yoga”, “counseling during the IAYT treatment”, duration of treatment), play an integrated role in reaching the “aim of IAYT” and experiencing “improvements and changes”. Conclusion: The IAYT is a holistic program and the ability of the patient to cooperate with and integrate the available factors (therapist related and treatment related) could enable best results.

GPs' approach to insulin prescribing in older patients: a qualitative study  

PubMed Central

Background Evidence suggests that insulin is under-prescribed in older people. Some reasons for this include physician's concerns about potential side-effects or patients' resistance to insulin. In general, however, little is known about how GPs make decisions related to insulin prescribing in older people. Aim To explore the process and rationale for prescribing decisions of GPs when treating older patients with type 2 diabetes. Design of study Qualitative individual interviews using a grounded theory approach. Setting Primary care. Method A thematic analysis was conducted to identify themes that reflected factors that influence the prescribing of insulin. Results Twenty-one GPs in active practice in Ontario completed interviews. Seven factors influencing the prescribing of insulin for older patients were identified: GPs' beliefs about older people; GPs' beliefs about diabetes and its management; gauging the intensity of therapy required; need for preparation for insulin therapy; presence of support from informal or formal healthcare provider; frustration with management complexity; and GPs' experience with insulin administration. Although GPs indicated that they would prescribe insulin allowing for the above factors, there was a mismatch in intended approach to prescribing and self-reported prescribing. Conclusion GPs' rationale for prescribing (or not prescribing) insulin is mediated by both practitioner-related and patient-related factors. GPs intended and actual prescribing varied depending on their assessment of each patient's situation. In order to improve prescribing for increasing numbers of older people with type 2 diabetes, more education for GPs, specialist support, and use of allied health professionals is needed.

Evaluation of interventions on road traffic injuries in Peru: a qualitative approach  

PubMed Central

Background Evaluation of interventions on road traffic injuries (RTI) going beyond the assessment of impact to include factors underlying success or failure is an important complement to standard impact evaluations. We report here how we used a qualitative approach to assess current interventions implemented to reduce RTIs in Peru. Methods We performed in-depth interviews with policymakers and technical officers involved in the implementation of RTI interventions to get their insight on design, implementation and evaluation aspects. We then conducted a workshop with key stakeholders to analyze the results of in-depth interviews, and to further discuss and identify key programmatic considerations when designing and implementing RTI interventions. We finally performed brainstorming sessions to assess potential system-wide effects of a selected intervention (Zero Tolerance), and to identify adaptation and redesign needs for this intervention. Results Key programmatic components were consistently identified that should be considered when designing and implementing RTI interventions. They include effective and sustained political commitment and planning; sufficient and sustained budget allocation; training, supervision, monitoring and evaluation of implemented policies; multisectoral participation; and strong governance and accountability. Brainstorming sessions revealed major negative effects of the selected intervention on various system building blocks. Conclusions Our approach revealed substantial caveats in current RTI interventions in Peru, and fundamental negative effects on several components of the sectors and systems involved. It also highlighted programmatic issues that should be applied to guarantee an effective implementation and evaluation of these policies. The findings from this study were discussed with key stakeholders for consideration in further designing and planning RTI control interventions in Peru. PMID:22269578

Acceptance of chronic neuropathic pain in spinal cord injured persons: a qualitative approach.  


Chronic neuropathic pain (CNP) in spinal cord injury (SCI) is a significant problem that has physical, functional, and psychosocial repercussions beyond the consequences of SCI. The notion that acceptance may be a viable alternative to suffering when resolution of pain is unattainable was explored. Studies indicate that acceptance of pain is associated with lower pain intensity, less pain-related anxiety and avoidance, less depression, less physical and psychosocial disability, more daily active time, and improved work status in patients who have other types of chronic pain. This exploratory qualitative study examined acceptance of pain in SCI individuals who have CNP. Grounded theory was used to develop a conceptual framework to describe acceptance in people with CNP and SCI. Data were obtained from in-depth interviews with seven SCI individuals. Six phases were identified, including: "comprehending the perplexity of CNP," "seeking pain resolution," "acknowledging pain permanence," "redefining core values," "learning to live with the pain," and "integrating pain." Two driving forces, "increasing independence" and "evolving pain view," were noted to move the process of acceptance forward. The findings in this study suggest that acceptance of pain appeared to be beneficial in terms of reducing suffering and facilitating a more satisfying and fulfilling life in these SCI individuals. A decreased emphasis on continued searching for a cure for CNP and movement toward a self-management approach was associated with increased pain coping for these SCI individuals. Clinical implications suggest that early intervention to facilitate effective coping and an exploration of the notion of acceptance could be beneficial. PMID:23158703

Measures of safeguard and rehabilitation for landscape protection planning: a qualitative approach based on diversity indicators.  


Maintaining existing levels of landscape diversity is becoming more and more important for planning considering the increasing pressures on agricultural ecosystems due to soil sealing, sprawl processes and intensive agriculture. Norms for land-use regulation and measures for landscape Safeguard and Rehabilitation have to take into consideration these threats in landscape planning. Evaluating the diversity of agricultural ecosystems is a fundamental step for proposing sound approaches to planning and managing both soil and landscape, as well as maintaining the related ecosystem services. The paper proposes a method aimed at the qualitative evaluation of spatial diversity of agricultural landscapes using a reduced set of ecological indicators based on land-use vector data. Indicators are calculated for defined landscape units characterized by landscape homogeneity. GIS geoprocessing and spatial analysis functions are employed. The study area is the Province of Enna in Sicily (Italy), which is characterized by cultivation mosaics in its southern region, cereal cultivation in the central region and prevailing natural environments in the northern region. Results from the indicator calculations are used to define measures to be included in a Landscape Protection Plan. Safeguard and Rehabilitation measures are introduced, which link indicator scores to planning protection aims. The results highlight the relevance of some agricultural mosaics in proximity to streams and seasonal fluvial environments, where some undamaged natural environments are still present. For these areas, specific landscape safeguard measures are proposed to preserve their diversity features together with their original agricultural functions. The work shows that even with a reduced number of indicators, a differentiated set of measures can be proposed for a Landscape Protection Plan. PMID:23388187

Comparison of optical model results from a microscopic Schrödinger approach to nucleon-nucleus elastic scattering with those from a global Dirac phenomenology  

E-print Network

Comparisons are made between results of calculations for intermediate energy nucleon-nucleus scattering for 12C, 16O, 40Ca, 90Zr, and 208Pb, using optical potentials obtained from global Dirac phenomenology and from a microscopic Schr\\"odinger model. Differential cross sections and spin observables for scattering from the set of five nuclei at 65 MeV and 200 MeV have been studied to assess the relative merits of each approach. Total reaction cross sections from proton-nucleus and total cross sections from neutron-nucleus scattering have been evaluated and compared with data for those five targets in the energy range 20 MeV to 800 MeV. The methods of analyses give results that compare well with experimental data in those energy regimes for which the procedures are suited.

Wandering behavior and attempted exits among residents diagnosed with dementia-related illnesses: a qualitative approach.  


Exiting attempts and wandering behavior among residents diagnosed with dementia-related illnesses were investigated. Residents were exposed to three test conditions: a mini-blind that concealed the view from the door, a cloth panel that concealed the panic bar of the door, and both the mini-blind and the cloth panel. During these test conditions, qualitative observations were conducted in addition to recording the attempted exits. The purpose of this paper is to present the qualitative findings in relationship to a model developed. The findings suggests that residents seemed to exit due to goal-orientation, exit-seeking behaviors, and attraction to the panic bar. PMID:9870039

Phenomenology from the Lattice  

E-print Network

In recent years the precision of lattice calculations has improved hugely, and the results are making a very significant impact in particle physics phenomenology. Indeed there is no alternative general method which can be used in the evaluation of nonperturbative strong interaction effects for a wide variety of physical processes. In this talk I discuss a selection of topics in flavour physics, including \\textit{mature} quantities for which lattice calculations have been performed for a long time (e.g. the determination of the $V_{us}$ CKM matrix element and $B_K$), quantities which we are now learning to study (e.g. $K\\to\\pi\\pi$ decays amplitudes and the spectrum and mixing of $\\eta-\\eta^\\prime$ mesons) and important phenomenological quantities for which a large amount of experimental data is available but which we do not yet understand how to approach in lattice simulations (e.g. nonleptonic B-decays). The improvement in precision and the extension of the range of processes which can be studied using lattice QCD has to be continued vigorously if precision flavour physics is to play a complementary role to large $p_\\perp$ discovery experiments at the LHC in unravelling the next level of fundamental physics.

A qualitative study of the determinants of dieting and non-dieting approaches in overweight/obese Australian adults  

PubMed Central

Background Dieting has historically been the main behavioural treatment paradigm for overweight/obesity, although a non-dieting paradigm has more recently emerged based on the criticisms of the original dieting approach. There is a dearth of research contrasting why these approaches are adopted. To address this, we conducted a qualitative investigation into the determinants of dieting and non-dieting approaches based on the perspectives and experiences of overweight/obese Australian adults. Methods Grounded theory was used inductively to generate a model of themes contrasting the determinants of dieting and non-dieting approaches based on the perspectives of 21 overweight/obese adults. Data was collected using semi-structured interviews to elicit in-depth individual experiences and perspectives. Results Several categories emerged which distinguished between the adoption of a dieting or non-dieting approach. These categories included the focus of each approach (weight/image or lifestyle/health behaviours); internal or external attributions about dieting failure; attitudes towards established diets, and personal autonomy. Personal autonomy was also influenced by another category; the perceived knowledge and self-efficacy about each approach, with adults more likely to choose an approach they knew more about and were confident in implementing. The time perspective of change (short or long-term) and the perceived identity of the person (fat/dieter or healthy person) also emerged as determinants of dieting or non-dieting approaches respectively. Conclusions The model of determinants elicited from this study assists in understanding why dieting and non-dieting approaches are adopted, from the perspectives and experiences of overweight/obese adults. Understanding this decision-making process can assist clinicians and public health researchers to design and tailor dieting and non-dieting interventions to population subgroups that have preferences and characteristics suitable for each approach.

The economic impact of the insured patients with severe chronic and acute illnesses: a qualitative approach  

PubMed Central

Background Little research has focused on the economic hardship among the insured with severe illnesses and high treatment costs, in particular, the consequence of poorer insurance coverage for high-cost illnesses. Therefore, we presented the case for identifying the experiences of insured patients with severe chronic and acute illnesses. This study identified a qualitative understanding of the economic impact of severe chronic and acute illnesses and household strategies to deal with high treatment costs. Design Interviews were conducted with 19 insured households of three different health insurance programs with a family member that had been hospitalized for severe chronic or acute illnesses in either Banyumas or Margono Sukarjo hospitals in Banyumas, Central Java, Indonesia. A thematic analysis was applied to guide the interpretation of the data. Results Insured households with a family member that had been hospitalized for severe chronic and acute illnesses were greatly affected by the high treatment costs. Four major issues emerged from this qualitative study: insured patients are still burdened with high out-of-pocket payments, households adopt various strategies to cope with the high cost of treatments, households experience financial hardships, and positive and negative perceptions of the insured regarding their health insurance coverage for acute and chronic illnesses. Conclusions Askes and Jamsostek patients faced financial burdens from high cost sharing for hospital amenities, non-covered drugs, and treatments and other indirect costs. Meanwhile, Jamkesmas beneficiaries faced no financial burden for related medical services but were rather burdened with indirect costs for the carers. Households relied on internal resources to cover hospital bills as the first strategy, which included the mobilization of savings, sale of assets, and borrowing of money. External support was tapped secondarily and included financial support from extended family members, donations from neighbors and the community, and additional benefits from employers. However, insured households overall had positive perceptions of insurance. PMID:25308817

Quantitative and qualitative approaches to identifying migration chronology in a continental migrant.  


The degree to which extrinsic factors influence migration chronology in North American waterfowl has not been quantified, particularly for dabbling ducks. Previous studies have examined waterfowl migration using various methods, however, quantitative approaches to define avian migration chronology over broad spatio-temporal scales are limited, and the implications for using different approaches have not been assessed. We used movement data from 19 female adult mallards (Anas platyrhynchos) equipped with solar-powered global positioning system satellite transmitters to evaluate two individual level approaches for quantifying migration chronology. The first approach defined migration based on individual movements among geopolitical boundaries (state, provincial, international), whereas the second method modeled net displacement as a function of time using nonlinear models. Differences in migration chronologies identified by each of the approaches were examined with analysis of variance. The geopolitical method identified mean autumn migration midpoints at 15 November 2010 and 13 November 2011, whereas the net displacement method identified midpoints at 15 November 2010 and 14 November 2011. The mean midpoints for spring migration were 3 April 2011 and 20 March 2012 using the geopolitical method and 31 March 2011 and 22 March 2012 using the net displacement method. The duration, initiation date, midpoint, and termination date for both autumn and spring migration did not differ between the two individual level approaches. Although we did not detect differences in migration parameters between the different approaches, the net displacement metric offers broad potential to address questions in movement ecology for migrating species. Ultimately, an objective definition of migration chronology will allow researchers to obtain a comprehensive understanding of the extrinsic factors that drive migration at the individual and population levels. As a result, targeted conservation plans can be developed to support planning for habitat management and evaluation of long-term climate effects. PMID:24130732

Understanding Trends : A Qualitative Approach to Trend Identification and their Statistical Significance  

NASA Astrophysics Data System (ADS)

Identifying trends in time series is necessary to increase the confidence level of the analysis of climate data. This entails finding trends that are statistically significant and categorizing them as linear, quadratic or cubic. Current methods identifying trends use various techniques such as polynomial regression, variate differencing and others. We propose methods such as boot strapping and frequency domain analysis that additionally address other key issues such as identifying the presence of trends within a segment of the time series and computing their individual statistical significances, and further perform a qualitative analysis in finally understanding how trend removal affects global statistics. The methods proposed play an important role in data driven discovery of climate dipoles that represent pairs of regions for which climate anomaly time series are in opposite polarities to each other. In such cases, the methods proposed can be used to identify spurious negative correlations that are caused primarily due to trends but not due to climate teleconnections. Given the general applicability of these methods, it may also prove useful to many time series data other than climate. This research is funded by NSF grant 1029711.

A model-driven approach to qualitatively assessing the added value of community coalitions.  


Community-based coalitions are commonly formed to plan and to carry out public health interventions. The literature includes evaluations of coalition structure, composition, and functioning; evaluations of community-level changes achieved through coalition activities; and the association between coalition characteristics and various indicators of success. Little information is available on the comparative advantage or "added value" of conducting public health interventions through coalitions as opposed to less structured collaborative mechanisms. This paper describes a qualitative, iterative process carried out with site representatives of the Controlling Asthma in American Cities Project (CAACP) to identify outcomes directly attributable to coalitions. The process yielded 2 complementary sets of results. The first were criteria that articulated and limited the concept of "added value of coalitions". The criteria included consensus definitions, an organizing figure, a logic model, and inclusion/exclusion criteria. The second set of results identified site-specific activities that met the definitional criteria and were, by agreement, examples of CAACP coalitions' added value. Beyond the specific findings relevant to the added value of coalitions in this project, the use of a social ecological model to identify the components of added value and the placement of those components within a logic model specific to coalitions should provide useful tools for those planning and assessing coalition-based projects.

Understanding Breastfeeding Initiation and Continuation in Rural Communities: A Combined Qualitative/Quantitative Approach  

PubMed Central

Objective To determine factors associated with breastfeeding in rural communities. Methods We combined qualitative and quantitative data from the Family Life Project, consisting of: (1) a longitudinal cohort study (N = 1292) of infants born September 2003–2004 and (2) a parallel ethnographic study (N = 30 families). Demographic characteristics, maternal and infant health factors, and health services were used to predict breastfeeding initiation and discontinuation using logistic and Cox regression models, respectively. Ethnographic interviews identified additional reasons for not initiating or continuing breastfeeding. Results Fifty-five percent of women initiated breastfeeding and 18% continued for at least 6 months. Maternal employment at 2 months and receiving WIC were associated with decreased breastfeeding initiation and continuation. Ethnographic data suggested that many women had never even considered breastfeeding and often discontinued breastfeeding due to discomfort, embarrassment, and lack of assistance. Conclusions Breastfeeding rates in these rural communities lag behind national averages. Opportunities for increasing breastfeeding in rural communities include enhancing workplace support, maximizing the role of WIC, increasing hospital breastfeeding assistance, and creating a social environment in which breastfeeding is normative.

Causal Set Phenomenology  

E-print Network

Central to the development of any new theory is the investigation of the observable consequences of the theory. In the search for quantum gravity, research in phenomenology has been dominated by models violating Lorentz invariance (LI) -- despite there being, at present, no evidence that LI is violated. Causal set theory is a LI candidate theory of QG that seeks not to quantise gravity as such, but rather to develop a new understanding of the universe from which both GR and QM could arise separately. The key hypothesis is that spacetime is a discrete partial order: a set of events where the partial ordering is the physical causal ordering between the events. This thesis investigates Lorentz invariant QG phenomenology motivated by the causal set approach. Massive particles propagating in a discrete spacetime will experience diffusion in both position and momentum in proper time. This thesis considers this idea in more depth, providing a rigorous derivation of the diffusion equation in terms of observable cosmic time. The diffusion behaviour does not depend on any particular underlying particle model. Simulations of three different models are conducted, revealing behaviour that matches the diffusion equation despite limitations on the size of causal set simulated. The effect of spacetime discreteness on the behaviour of massless particles is also investigated. Diffusion equations in both affine time and cosmic time are derived, and it is found that massless particles undergo diffusion and drift in energy. Constraints are placed on the magnitudes of the drift and diffusion parameters by considering the blackbody nature of the CMB. Spacetime discreteness also has a potentially observable effect on photon polarisation. For linearly polarised photons, underlying discreteness is found to cause a rotation in polarisation angle and a suppression in overall polarisation.

Jordanian men's attitudes and views of birth-spacing and contraceptive use (a qualitative approach).  


This qualitative study was carried out to understand the meaning that Jordanian men attach to birth-spacing/family planning and to identify their attitudes and practices regarding contraceptives. Six focus group discussions were conducted over a 3-month period starting April 1996, with each group containing 6-10 men. The sample consisted of Jordanian men residing in Amman. Education, social class, and marital status stratified men's selection. The discussions were moderated by a social psychologist of the same sex. With respondents' consent, data gathered in the discussion groups were tape-recorded, transcribed, and critically analyzed using the content analysis method. The researchers found that there was a consensus among all men about the link between the concept of birth-spacing/family planning and the concept of better health for the mother and the child. Yet, the practice of contraception was influenced by some religious and cultural beliefs including that of "RIZK" (or fortune) which comes when the child is born. Moreover, some knowledge deficits concerning modern methods of contraception, and their side effects in particular, were noted. Some unfavorable attitudes of men for themselves using male contraceptives were also noted. Most men in the study indicated that spousal communication takes place on issues related to family planning, but the final decision is, in most cases, left to the husband alone (the head of the house). The demand for an increasing number of male children and the resistance of males to use condoms were among the most prevalent unexpected phenomena noticed in this study. The study concludes by recommending that special attention be directed to males when delivering family planning services. PMID:12418974

Quantum Spacetime Phenomenology  

E-print Network

I review the current status of phenomenological programs inspired by quantum-spacetime research. I stress in particular the significance of results establishing that certain data analyses provide sensitivity to effects introduced genuinely at the Planck scale. And my main focus is on phenomenological programs that managed to affect the directions taken by studies of quantum-spacetime theories.

Genotoxicity testing: moving beyond qualitative "screen and bin" approach towards characterization of dose-response and thresholds.  


For more than 40+ years, genotoxicity data have been interpreted in a qualitative, binary mode; a chemical is considered either positive or negative for a response in the test system. Although dose-response information is sometimes used in this decision, it is not routine to obtain the amount of information needed to inform risk assessment, for example to determine no-observed-genotoxic-effect-levels, primarily due to the historical view of genotoxic responses as "linear, no-threshold." Only recently have researchers begun to address this issue through robust experimental designs and application of statistical models. A growing body-of-evidence supports the existence of response thresholds for a number of mutagenic agents, in vitro and in vivo. Clearly, simple observation of a "hockey-stick" dose-response curve is not sufficient to establish a threshold. Collection of robust empirical data must be supported with an analysis of biological plausibility for the observed threshold. In this context, a chemical-specific mode-of-action (MOA) approach, which identifies key events responsible for the observed mutagenic effect, is extremely valuable. Biomarkers of key events, providing qualitative and quantitative information, can be integrated in a weight-of-evidence-based assessment of genotoxicity data from multiple test systems and used to identify data gaps to resolve/reduce uncertainties during the risk assessment process. To this end, specific recommendations on study design and data analysis are proposed. As the Environmental Mutagen Society celebrates its 40th anniversary, the field of genetic toxicology is marking a milestone on the path to a new paradigm, using a MOA, data-driven approach to answer questions about thresholds for genotoxic agents.

Alternative to consensus scoring--a new approach toward the qualitative combination of docking algorithms.  


Since the development of the first docking algorithm in the early 1980s a variety of different docking approaches and tools has been created in order to solve the docking problem. Subsequent studies have shown that the docking performance of most tools strongly depends on the considered target. Thus it is hard to choose the best algorithm in the situation at hand. The docking tools FlexX and AutoDock are among the most popular programs for docking flexible ligands into target proteins. Their analysis, comparison, and combination are the topics of this study. In contrast to standard consensus scoring techniques which integrate different scoring algorithms usually only by their rank, we focus on a more general approach. Our new combined docking workflow-AutoxX-unifies the interaction models of AutoDock and FlexX rather than combining the scores afterward which allows interpretability of the results. The performance of FlexX, AutoDock, and the combined algorithm AutoxX was evaluated on the basis of a test set of 204 structures from the Protein Data Bank (PDB). AutoDock and FlexX show a highly diverse redocking accuracy at the different complexes which assures again the usefulness of taking several docking algorithms into account. With the combined docking the number of complexes reproduced below an rmsd of 2.5 A could be raised by 10. AutoxX had a strong positive effect on several targets. The highest performance increase could be found when redocking 20 protein-ligand complexes of alpha-thrombin, plasmepsin, neuraminidase, and d-xylose isomerase. A decrease was found for gamma-chymotrypsin. The results show that--applied to the right target-AutoxX can improve the docking performance compared to AutoDock and FlexX alone. PMID:17492829

Approaches to Recording Drug Allergies in Electronic Health Records: Qualitative Study  

PubMed Central

Background Drug allergy represent an important subset of adverse drug reactions that is worthy of attention because many of these reactions are potentially preventable with use of computerised decision support systems. This is however dependent on the accurate and comprehensive recording of these reactions in the electronic health record. The objectives of this study were to understand approaches to the recording of drug allergies in electronic health record systems. Materials and Methods We undertook a case study comprising of 21 in-depth interviews with a purposefully selected group of primary and secondary care clinicians, academics, and members of the informatics and drug regulatory communities, observations in four General Practices and an expert group discussion with 15 participants from the Allergy and Respiratory Expert Resource Group of the Royal College of General Practitioners. Results There was widespread acceptance among healthcare professionals of the need for accurate recording of drug allergies and adverse drug reactions. Most drug reactions were however likely to go unreported to and/or unrecognised by healthcare professionals and, even when recognised and reported, not all reactions were accurately recorded. The process of recording these reactions was not standardised. Conclusions There is considerable variation in the way drug allergies are recorded in electronic health records. This limits the potential of computerised decision support systems to help alert clinicians to the risk of further reactions. Inaccurate recording of information may in some instances introduce new problems as patients are denied treatments that they are erroneously believed to be allergic to. PMID:24740090

Tomographic thallium-201 myocardial perfusion scintigrams after maximal coronary artery vasodilation with intravenous dipyridamole: comparison of qualitative and quantitative approaches  

SciTech Connect

Eighty-six patients had thallium-201 (/sup 201/Tl) myocardial perfusion scintigrams after intense coronary artery dilation with i.v. dipyridamole. Tomographic and planar /sup 201/Tl scintigrams were obtained in each patient. Tomographic scintigrams were interpreted using quantitative or visual criteria; planar scintigrams were assessed using visual criteria only. When visual criteria were used, interobserver variability was 40% for tomographic scintigrams and 44% for planar scintigrams. In the 24 patients with normal or nonsignificant CAD, quantitative analysis of the tomograms (range approach) indicated that one of 24 (4%) had a positive image (specificity 96%%); in contrast, when visual criteria were used to interpret the tomographic or planar /sup 201/Tl scintigrams, eight of 24 (33%) had positive scintigrams (specificity 67%). In the 51 abnormal patients, the sensitivity of detecting CAD was 46 of 51 (90%) for tomographic scintigrams interpreted quantitatively, 39 of 51 (76%) for tomographic scintigrams interpreted visually and 41 of 51 (80%) for planar scintigrams assessed visually. The tomographic imaging procedure (quantitative interpretation) also demonstrated a high sensitivity (89%) and specificity (100%) in 28 patients (10 normal and 18 CAD), with a clinical diagnosis of unstable angina pectoris. Overall, the predictive accuracy of an abnormal scintigram with quantitative tomographic imaging (98%) was significantly better (p<0.05) than either qualitative planar or pinhole imaging. (JMT)

Internal motivations and barriers effective on the healthy lifestyle of middle-aged women: A qualitative approach  

PubMed Central

Background: A healthy lifestyle is one of the basic health-promotion strategies. Several factors are involved in shaping health-promotion behaviors. The internal barriers are the opinion and feelings that surround the individual and are the reasons that complicate the change of behavior. The aim of this study was to identify internal motivations and barriers effective on the healthy lifestyle in middle-aged Iranian women. Materials and Methods: This was a qualitative study based on content analysis of in-depth semi-structured interviews with 21 middle-aged women in the city of Yazd, who were selected using purposeful sampling approach. The interviews continued until data saturation was reached; and the interviews were audio-recorded and transcribed exactly. The transcripts were analyzed. Results: Five main themes emerged from the analysis of the interviews: Women’s knowledge of health-promoting behaviors, importance of health and healthy behavior of women, affliction or fear of affliction to chronic disease and its consequences, responsibilities of women in the family and society, and skills of life management in women. Conclusion: The findings suggest that empowering individual participants in health promotion is the most important factor determining their health. Thus, designing appropriate programs for education and empowerment of people is essential to promoting health. Health policy makers, with knowledge of these factors, can design comprehensive, socialization programs to promote women’s health. PMID:23853654

From model conception to verification and validation, a global approach to multiphase Navier-Stoke models with an emphasis on volcanic explosive phenomenology  

SciTech Connect

Large-scale volcanic eruptions are hazardous events that cannot be described by detailed and accurate in situ measurement: hence, little to no real-time data exists to rigorously validate current computer models of these events. In addition, such phenomenology involves highly complex, nonlinear, and unsteady physical behaviors upon many spatial and time scales. As a result, volcanic explosive phenomenology is poorly understood in terms of its physics, and inadequately constrained in terms of initial, boundary, and inflow conditions. Nevertheless, code verification and validation become even more critical because more and more volcanologists use numerical data for assessment and mitigation of volcanic hazards. In this report, we evaluate the process of model and code development in the context of geophysical multiphase flows. We describe: (1) the conception of a theoretical, multiphase, Navier-Stokes model, (2) its implementation into a numerical code, (3) the verification of the code, and (4) the validation of such a model within the context of turbulent and underexpanded jet physics. Within the validation framework, we suggest focusing on the key physics that control the volcanic clouds—namely, momentum-driven supersonic jet and buoyancy-driven turbulent plume. For instance, we propose to compare numerical results against a set of simple and well-constrained analog experiments, which uniquely and unambiguously represent each of the key-phenomenology. Key

Experience of fibromyalgia. Qualitative study.  

PubMed Central

OBJECTIVE: To explore illness experiences of patients diagnosed with fibromyalgia. DESIGN: Qualitative method of in-depth interviews. SETTING: Midsize city in Ontario. PARTICIPANTS: Seven patients diagnosed with fibromyalgia. METHOD: Seven in-depth interviews were conducted to explore the illness experience of patients diagnosed with fibromyalgia. All interviews were audiotaped and transcribed verbatim. All interview transcriptions were read independently by the researchers, who then compared and combined their analysis. Final analysis involved examining all interviews collectively, thus permitting relationships between and among central themes to emerge. The analysis strategy used a phenomenologic approach and occurred concurrently rather than sequentially. MAIN FINDINGS: Themes that emerged from the interpretive analysis depict patients' journeys along a continuum from experiencing symptoms, through seeking a diagnosis, to coping with the illness. Experiencing symptoms was composed of four subcategories: pain, a precipitating event, associated symptoms, and modulating factors. Seeking a diagnosis entailed frustration and social isolation. Confirmation of diagnosis brought relief as well as anxiety about the future. After diagnosis, several steps led to creation of adaptive coping strategies, which were influenced by several factors. CONCLUSION: Findings suggest that the conventional medical model fails to address the complex experience of fibromyalgia. Adopting a patient-centred approach is important for helping patients cope with this disease. PMID:10845136

Phenomenology as research method or substantive metaphysics? An overview of phenomenology's uses in nursing.  


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.

Models and phenomenology  

E-print Network

It is evident that models of the knee should match the observational phenomenology. In this talk I discuss a few aspects of phenomenology, which are important not only for the understanding of the knee origin, but also for the general problem of the origin of cosmic rays. Among them are the shape of the energy spectrum, its irregularity, the sharpness of the knee and its fine structure. The classification of models is given and some examples of the most recent models are discussed. The most probable conclusion deduced from this examination is that the knee has an astrophysical origin and the so called 'source' models of the knee are most likely among them.

Cyclotide Structure-Activity Relationships: Qualitative and Quantitative Approaches Linking Cytotoxic and Anthelmintic Activity to the Clustering of Physicochemical Forces  

PubMed Central

Cyclotides are a family of plant-derived proteins that are characterized by a cyclic backbone and a knotted disulfide topology. Their cyclic cystine knot (CCK) motif makes them exceptionally resistant to thermal, chemical, and enzymatic degradation. Cyclotides exert much of their biological activity via interactions with cell membranes. In this work, we qualitatively and quantitatively analyze the cytotoxic and anthelmintic membrane activities of cyclotides. The qualitative and quantitative models describe the potency of cyclotides using four simple physicochemical terms relevant to membrane contact. Specifically, surface areas of the cyclotides representing lipophilic and hydrogen bond donating properties were quantified and their distribution across the molecular surface was determined. The resulting quantitative structure-activity relation (QSAR) models suggest that the activity of the cyclotides is proportional to their lipophilic and positively charged surface areas, provided that the distribution of these surfaces is asymmetric. In addition, we qualitatively analyzed the physicochemical differences between the various cyclotide subfamilies and their effects on the cyclotides' orientation on the membrane and membrane activity.

A phenomenological approach to the ethics of transplantation medicine: sociality and sharing when living-with and dying-with others.  


Recent years have seen a rise in the number of sociological, anthropological, and ethnological works on the gift metaphor in organ donation contexts, as well as in the number of philosophical and theological analyses of giving and generosity, which has been mirrored in the ethical debate on organ donation. In order to capture the breadth of this field, four frameworks for thinking about bodily exchanges in medicine have been distinguished: property rights, heroic gift-giving, sacrifice, and gift-giving as aporia. Unfortunately, they all run into difficulties in terms of both making sense of the relational dimensions of postmortem and live organ donations and being normatively adequate in the sense of shedding light and providing guidance on ethical concerns when body parts are donated. For this reason, this article presents a phenomenological framework of giving-through-sharing, based on Maurice Merleau-Ponty's philosophy. This framework makes sense of relational dimensions of postmortem and live organ donation. It also sheds light on three highly debated concerns in organ donation ethics: indebtedness on the part of recipients, the fact that some live donors do not experience donation as a matter of choice, and the potentially painful experience of donors' relatives, who need to make decisions about postmortem organ donation at a time of bereavement. It can indirectly support what may be called a normalization of bodily exchanges in medicine. PMID:25227276

We also examine compactifications with 5-d gauge fields, in which case the holographic dual is a broken CFT weakly coupled to dynamical gauge fields in addition to gravity. The holographic picture is used to clarify a number of important phenomenological issues in these and related models, including the questions of black hole production, radius stabilization, early universe cosmology, and gauge coupling unification.

Psychoanalysis--a phenomenology of language.  


It is often said that there is an unbridgeable gap between phenomenology and psychoanalysis. But this is only half the truth. Starting from Merleau-Ponty's proposal of an objectivistic and an idealistic divergence of Freud's enterprise the paper tries to reconstruct two possible movements: the objectivistic divergence of Husserl's enterprise as a phenomenological shift towards psychoanalysis and the idealistic divergence of Freud's enterprise as a psychoanalytical shift towards phenomenology. It is shown that this approach is possible on the field of language and semiotics where psychic life, as the essence of our subjectivity, may be rendered as a uniform phenomenon of an articulation in the world of signs. This thesis is elucidated at the end of the paper by discussing first (to the phenomenological side) a certain interpretation of the use of Husserl's reduction as a method of investigation in psychiatry and second (to the psychoanalytic side) the importance of Lacan's difference between repression and foreclosure for a psychopathological understanding of psychosis.

What Do Resource-Oriented Approaches Mean to General Practitioners and How Can They Be Facilitated in Primary Care? A Qualitative Study  

PubMed Central

Although resource orientation, as a part of health promotion, should play a major role in general practice, the anchoring and realization of resource-oriented approaches remain small in Germany. The aim of this study was to analyze what resource orientation means to general practitioners (GPs) and develop strategies as to how this can be facilitated in GP practice. Within a qualitative research approach, 19 semi-structured telephone interviews were recorded, transcribed, and analyzed using qualitative content analysis. Within the interviews, the inclusion of the patients' individual resources is described as core competence of GPs. Supporting the patients' disease coping strategies and self-help were seen as important by GPs. However, perceptions as to which resources are considered to be fundamental ranged widely across the participant group. The results confirm the important role of resource-oriented approaches in general practice. However, a general definition of resource orientation is needed. In addition, working conditions for GPs need to be taken into account to ensure that these contribute to a healthy work-life balance. The need for GP training was identified to improve communication skills. Further integration of GPs in health promotion and communal structures would be beneficial. PMID:23986779

Evaluation of factors influencing child abuse leading to oro-facial lesions in Isfahan, Iran: A qualitative approach  

PubMed Central

Background: Since child abuse and neglect are serious conditions which can potentially lead to inappropriate dental health, we conducted this qualitative study to define the factors influencing child abuse and neglect, which lead to oro-facial lesions. Materials and Methods: Qualitative semi-structured interviews were conducted by social services employees. Purposive sampling was used to recruit participants to capture a range of experiences such as the physical abuse, sexual abuse, role of family in child abuse, age, and gender. Results: Participants demonstrated a range of perceptions which lead to child abuse including hitting on the head and slapping. Often subsidiary to this view, several factors were mentioned that occasionally influenced child abuse. These factors appeared to be idiosyncratic but could be drawn together into three categories: Cultural lacks which includes poverty, cruelty of parents and addiction, psychological disorders, and separation in the family which was seen in most of the children. Conclusion: This study has identified a variety of factors influencing the incidence of child abuse. Therefore, dentists should meticulously pay attention to children who have these risk factors in order to discover child abuse events. Quantitative research would reveal the extent of these factors. Dentists’ knowledge of their roles in managing cases suffering from abuse might need to be assessed to see if dentists need further education in this important area. PMID:23559930

Planck-Length Phenomenology  

E-print Network

This author's recent proposal of interferometric tests of Planck-scale-related properties of space-time is here revisited from a strictly phenomenological viewpoint. The results announced previously are rederived using elementary dimensional considerations. The dimensional analysis is then extended to the other two classes of experiments (observations of neutral kaons at particle accelerators and observations of the gamma rays we detect from distant astrophysical sources) which have been recently considered as opportunities to explore "foamy" properties of space-time. The emerging picture suggests that there is an objective and intuitive way to connect the sensitivities of these three experiments with the Planck length. While in previous studies the emphasis was always on some quantum-gravity scenario and the analysis was always primarily aimed at showing that the chosen scenario would leave a trace in a certain class of doable experiments, the analysis here reported takes as starting point the experiments and, by relating in a direct quantitative way the sensitivities to the Planck length, provides a model-independent description of the status of Planck-length phenomenology.

Superstrings, Phenomenology and F-theory  

E-print Network

We give brief ideas on building gauge models in superstring theory, especially the four-dimensional models obtained from the compactification of F-theory. According to Vafa, we discuss the construction of F-theory to approach non-perturbative aspects of type IIB superstring. Then, we present local models of F-theory, which can generate new four-dimensional gauge models with applications to phenomenology.

Phenomenology of turbulent dynamo growth and saturation  

E-print Network

With a non local shell model of magnetohydrodynamic turbulence we investigate numerically the turbulent dynamo action for low and high magnetic Prandtl numbers ($Pm$). The results obtained in the kinematic regime and along the way to dynamo saturation are understood in terms of a phenomenological approach based on the local ($Pm\\ll 1$) or non local ($Pm\\gg 1$) nature of the energy transfers. In both cases the magnetic energy grows at small scale and saturates as an inverse `` cascade ''.

Perceived efficacy of e-cigarettes versus nicotine replacement therapy among successful e-cigarette users: a qualitative approach  

PubMed Central

Background Nicotine is widely recognized as an addictive psychoactive drug. Since most smokers are bio-behaviorally addicted, quitting can be very difficult and is often accompanied by withdrawal symptoms. Research indicates that nicotine replacement therapy (NRT) can double quit rates. However, the success rate for quitting remains low. E-cigarettes (electronic cigarettes) are battery-powered nicotine delivery devices used to inhale doses of vaporized nicotine from a handheld device similar in shape to a cigarette without the harmful chemicals present in tobacco products. Anecdotal evidence strongly suggests that e-cigarettes may be effective in helping smokers quit and preventing relapse, but there have been few published qualitative studies, especially among successful e-cigarette users, to support this evidence. Methods Qualitative design using focus groups (N?=?11); 9 men and 2 women. Focus groups were conducted by posing open-ended questions relating to the use of e-cigarettes, comparison of effectiveness between NRTs and e-cigarettes, barriers to quitting, and reasons for choosing e-cigarettes over other methods. Results Five themes emerged that describe users’ perceptions of why e-cigarettes are efficacious in quitting smoking: 1) bio-behavioral feedback, 2) social benefits, 3) hobby elements, 4) personal identity, and 5) distinction between smoking cessation and nicotine cessation. Additionally, subjects reported their experiences with NRTs compared with e-cigarettes, citing negative side effects of NRTs and their ineffectiveness at preventing relapse. Conclusion These findings suggest tobacco control practitioners must pay increased attention to the importance of the behavioral and social components of smoking addiction. By addressing these components in addition to nicotine dependence, e-cigarettes appear to help some tobacco smokers transition to a less harmful replacement tool, thereby maintaining cigarette abstinence.

Experiences of non-progressive and augmented labour among nulliparous women: a qualitative interview study in a Grounded Theory approach  

PubMed Central

Background Non-progressive labour is the most common complication in nulliparas and is primarily treated by augmentation. Augmented labour is often terminated by instrumental delivery. Little qualitative research has addressed experiences of non-progressive and augmented deliveries. The aim of this study was to gain a deeper understanding of the experience of non-progressive and augmented labour among nulliparas and their experience of the care they received. Methods A qualitative study was conducted using individual interviews. Data was collected and analysed according to the Grounded Theory method. The participants were a purposive sample of ten women. The interviews were conducted 4–15 weeks after delivery. Results The women had contrasting experiences during the birth process. During labour there was a conflict between the expectation of having a natural delivery and actually having a medical delivery. The women experienced a feeling of separation between mind and body. Interacting with the midwife had a major influence on feelings of losing and regaining control. Reconciliation between the contrasting feelings during labour was achieved. The core category was named Dialectical Birth Process and comprised three categories: Balancing natural and medical delivery, Interacting, Losing and regaining control. Conclusion A dialectical process was identified in these women's experiences of non-progressive labour. The process is susceptible to interaction with the midwife; especially her support to the woman's feeling of being in control. Midwives should secure that the woman's recognition of the fact that the labour is non-progressive and augmentation is required is handled with respect for the dialectical process. Augmentation of labour should be managed as close to the course of natural labour and delivery as possible. PMID:17662152

Barriers to and facilitators for screening women for intimate partner violence in surgical fracture clinics: a qualitative descriptive approach  

PubMed Central

Background Intimate Partner Violence (IPV) is a major health issue that involves any physical, sexual or psychological harm inflicted by a current or former partner. Musculoskeletal injuries represent the second most prevalent clinical manifestation of IPV. Health care professionals, however, rarely screen women for IPV. Using qualitative methods, this study aimed to explore the perceived barriers to IPV screening and potential facilitators for overcoming these barriers among orthopaedic surgeons and surgical trainees. Methods We conducted three focus groups with orthopaedic surgeons, senior surgical trainees, and junior surgical trainees. A semi-structured focus group guide was used to structure the discussions. Transcripts and field notes from the focus groups were analyzed using the qualitative software program N’Vivo (version 10.0; QSR International, Melbourne, Australia). To further inform our focus group findings and discuss policy changes, we conducted interviews with two opinion leaders in the field of orthopaedics. Similar to the focus groups, the interviews were digitally recorded and transcribed, and then analyzed. Results In the analysis, four categories of barriers were identified: surgeon perception barriers; perceived patient barriers; fracture clinic barriers and orthopaedic health care professional barriers. Some of the facilitators identified included availability of a crisis team; development of a screening form; presence of IPV posters or buttons in the fracture clinic; and the need for established policy or government support for IPV screening. The interviewees identified the need for: the introduction of evidence-based policy aiming to increase awareness about IPV among health care professionals working within the fracture clinic setting, fostering local and national champions for IPV screening, and the need to generate change on a local level. Conclusions There are a number of perceived barriers to screening women in the fracture clinic for IPV, many of which can be addressed through increased education and training, and additional resources in the fracture clinic. Orthopaedic health care professionals are supportive of implementing an IPV screening program in the orthopaedic fracture clinic. PMID:23560744



Some phenomenology of intersecting D-brane models  

SciTech Connect

We present some phenomenology of a new class of intersecting D-brane models. Soft SUSY breaking terms for these models are calculated in the complex structure (u)-moduli dominant SUSY breaking approach (in type IIA). In this case, the dependence of the soft terms on the Yukawas and Wilson lines drops out. These soft terms have a different pattern compared to the usual heterotic string models. Phenomenological implications for dark matter are discussed.

Pulsed laser effects phenomenology  

SciTech Connect

A comprehensive overview of the phenomenology associated with the interaction of intense laser beams with matter is presented. The beam is assumed to be incident on a solid or liquid target located within a transport medium. The discussion is first categorized by the type of this medium; namely, vacuum, gas, liquid, solid or particulate. Then the dependence of the interaction is further classified by the laser flux, pulselength, wavelength and the target properties. The various classes of behavior are discussed along with the conditions for their occurrence. Classes discussed include: slow bulk heating, transparent vapor from the target surface, secondary energy transport to the ablation surface, laser absorption at the critical surface, shock induced blowoff, photoelectric cross section dependence on temperature and density, laser supported combustion and detonation, contained vaporization and Mie scattering. 21 refs., 2 figs.

HEMP internal coupling phenomenology study  

SciTech Connect

This report documents a task sponsored by DNA to unravel the electromagnetic coupling problem associated with the interaction of the high altitude electromagnetic pulse HEMP) with typical aerospace systems. A bottom up approach to this task has been selected. In this approach, tools are developed for measuring and predicting the responses of simple test systems; from these measurements and predictions phenomenological understanding of the coupling mechanisms may be obtained and the tools may be verified. The construction and the experimental characterization of a test system embodying the fundamental features of an interior coupling problem, is discussed. Experimental, computational and analytical tools has been applied to this test system. Experimental measurements have revealed a pronounced modal interior response which has been closely replicated with the time domain three dimensional finite difference code G3DXL3. The persistence of these modes has been established analytically with an N-series analysis. Focusing and reflection effects as well as hot spot formation have been examined with the N-series analysis and with a time domain two-dimensional finite element code GEM2D.

[Between anxiety and hope: the experiences of women with vulval intraepithelial neoplasia during their illness trajectory - a qualitative approach].  


The vulvar intraepithelial neoplasia (VIN) is a rare chronic skin condition that may progress to an invasive carcinoma of the vulva. Major issues affecting women's health were occurring symptoms, negative influences on sexuality, uncertainty concerning the illness progression and changes in the body image. Despite this, there is little known about the lived experiences of the illness trajectory. Therefore, the aim of this study was to describe the experiences of women with VIN during the illness trajectory. In a secondary data analysis of the foregoing qualitative study we analysed eight narrative interviews with women with VIN by using thematic analysis in combination with critical hermeneutics. Central for these women during their course of illness was a sense of "Hope and Fear". This constitutive pattern reflects the fear of recurrence but also the trust in healing. The eight narratives showed women's experiences during their course of illness occurred in five phases: "there is something unknown"; "one knows, what IT is"; "IT is treated and should heal"; "IT has effects on daily life"; "meanwhile it works". Women's experiences were particularly influenced by the feeling of "embarrassment" and by "dealing with professionals". Current care seems to lack adequate support for women with VIN to manage these phases. We suggest, based on our study and the international literature, that new models of counselling and providing information need to be developed and evaluated. PMID:23535473

Health Care Support Issues for Internationally Adopted Children: A Qualitative Approach to the Needs and Expectations of Families  

PubMed Central

Background Families of internationally adopted children may face specific problems with which general practitioners (GPs) may not be familiar. The aim of the study was to explore problems faced by families before, during and after the arrival of their internationally adopted child and to assess the usefulness of a specific medical structure for internationally adopted children, which could be a resource for the GP. Methodology/Principal Findings We conducted a qualitative study using individual semistructured guided conversations and interviewed 21 families that had adopted a total of 26 children internationally in the Puy de Dome department, France, in 2003. Quantitative data were used to describe the pathologies diagnosed and the investigations performed.Our study showed that the history of these families, from the start of the adoption project to its achievement, is complex and warrants careful analysis. Health-care providers should not only consider the medical aspects of adoption, but should also be interested in the histories of these families, which may play a role in the forming of attachments between the adoptee and their adoptive parents and prevent further trouble during the development of the child. We also showed that adoptive parents have similar fears or transient difficulties that may be resolved quickly by listening and reassurance. Most such families would support the existence of a specific medical structure for internationally adopted children, which could be a resource for the general practitioner. However, the health-care providers interviewed were divided on the subject and expressed their fear that a special consultation could be stigmatizing to children and families. Conclusions/Significance A specific consultation with well-trained and experienced practitioners acting in close collaboration with GPs and paediatricians may be of help in better understanding and supporting adopted children and their families.

Quantitative versus qualitative approaches: a comparison of two research methods applied to identification of key health issues for working horses in Lesotho.  


The relative merits and potential complementarity of participatory methods and classical epidemiological techniques in veterinary-related research is a current topic of discussion. Few reported studies have applied both methodologies within the same research framework to enable direct comparison. The aim of this study was to compare issues identified by a classical epidemiological study of horses and their owners with those identified by owner communities using participatory approaches. In 2009, a cross-sectional survey was undertaken as part of an impact assessment study of farrier and saddler training programmes, and a small-scale nutrition trial, implemented in Lesotho by a UK-based equine charity. In total, 245 horses and their 237 owners participated in the survey which comprised a face-to-face structured questionnaire covering knowledge and practices relating to equine husbandry and primary healthcare, clinical examination and sampling of horses, and examination of tack used on those horses. In early 2010, 56 owners in three survey regions, some of whom participated in the survey, attended a participatory workshop. Each workshop group created a local resource map whilst discussing and identifying key issues associated with horse ownership and what might have an adverse impact on horse health and work. Following map completion, each group began by prioritising the identified issues, and then ranked them using a pairwise/ranking matrix to reflect how important issues were in relation to each other. Overall priority issues were: mouth problems, hunger and nutrition, diseases (including infectious diseases, parasites and colic), husbandry (including wound management), and feet and limb problems. Major health issues identified by cross-sectional study included sharp enamel points on teeth, endo- and ectoparasite infestation, suboptimal nutrition, tack-associated wounds, overgrown and poorly balanced feet and poor owner husbandry knowledge and practices. Whilst common issues were identified through the two research approaches, key differences also emerged. The classical, more quantitative approach provided objective measurement of problem frequency, which was compared with owners' perceptions of importance. The qualitative participatory approach provided greater opportunity for researchers to gain detailed understanding of local issues and appreciate how owners defined and prioritised problems affecting them and their animals. Both approaches provided valuable and complementary information that can be used to inform interventions aimed at providing sustainable improvements in the health and wellbeing of working animals and their owners. It is recommended that both quantitative and qualitative approaches are employed as part of detailed needs assessment work prior to defining and prioritising the charity's future interventions.

Qualitative modelling for the Caeté Mangrove Estuary (North Brazil): a preliminary approach to an integrated eco-social analysis  

NASA Astrophysics Data System (ADS)

The sustainability of different integrated management regimes for the mangrove ecosystem of the Caeté Estuary (North Brazil) were assessed using a holistic theoretical framework. As a way to demonstrate that the behaviour and trajectory of complex whole systems are not epiphenomenal to the properties of the small parts, a set of conceptual models from more reductionistic to more holistic were enunciated. These models integrate the scientific information published until present for this mangrove ecosystem. The sustainability of different management scenarios (forestry and fishery) was assessed. Since the exploitation of mangrove trees is not allowed according Brazilian laws, the forestry was only included for simulation purposes. The model simulations revealed that sustainability predictions of reductionistic models should not be extrapolated into holistic approaches. Forestry and fishery activities seem to be sustainable only if they are self-damped. The exploitation of the two mangrove species Rhizophora mangle and Avicenia germinans does not appear to be sustainable, thus a rotation harvest is recommended. A similar conclusion holds for the exploitation of invertebrate species. Our results suggest that more studies should be focused on the estimation of maximum sustainable yield based on a multispecies approach. Any reference to holistic sustainability based on reductionistic approaches may distort our understanding of the natural complex ecosystems.

Fitting the phenomenological MSSM  

SciTech Connect

We perform a global Bayesian fit of the phenomenological minimal supersymmetric standard model (pMSSM) to current indirect collider and dark matter data. The pMSSM contains the most relevant 25 weak-scale MSSM parameters, which are simultaneously fit using 'nested sampling' Monte Carlo techniques in more than 15 years of CPU time. We calculate the Bayesian evidence for the pMSSM and constrain its parameters and observables in the context of two widely different, but reasonable, priors to determine which inferences are robust. We make inferences about sparticle masses, the sign of the {mu} parameter, the amount of fine-tuning, dark matter properties, and the prospects for direct dark matter detection without assuming a restrictive high-scale supersymmetry breaking model. We find the inferred lightest CP-even Higgs boson mass as an example of an approximately prior-independent observable. This analysis constitutes the first statistically convergent pMSSM global fit to all current data.

[Phenomenology of dreams].  


A phenomenology of dreams searches for meaning, with the aim not only of explaining but also of understanding the experience. What and who is it for? And what about the nearly forgotten dream among the moderns, the banal returning to the nightmare, sleepiness, or dreamlike reverie. Nostalgia for the dream, where we saw a very early state of light, not a ordinaire qu duel. Regret for the dreamlike splendor exceeded by the modeling power of modern aesthetics--film and the explosion of virtual imaging technologies. Disappointment at the discovery of a cognitive permanence throughout sleep and a unique fit with the real upon awaking? An excess of methodological rigor where we validate the logic of the dream, correlating the clinical improvement in psychotherapy and the ability to interpret one's own dreams. The dangerous psychological access when the dream primarily is mine, viewed as a veiled expression of an unspoken desire, or when the dream reveals to me, in an existential conception of man, through time and space, my daily life, my freedom beyond my needs. Might its ultimate sense also mean its abolition? From the story of a famous forgotten dream, based on unexpected scientific data emerges the question: do we dream to forget? The main thing would not be consciousness but confidence, when " the sleeping man, his regard extinguished, dead to himself seizes the light in the night " (Heraclitus). PMID:22812163

Phenomenology of supersymmetric models with a singlet  

E-print Network

The supersymmetric extension of the standard model with an additional gauge singlet is analysed in detail in the light of the recent experimental bounds on supersymmetric particles. The useful part of the parameter space and the particle spectrum are displayed. We find that once the recent bounds on the chargino mass are imposed, all other new particles practically satisfy the present experimental limits. Special attention is given to particles to be searched for in the future experiments. The singlet fields tend to decouple and give rise to an effective MSSM, enlarging the validity of many phenomenological analyses based in the minimal field content. However, in some ranges of the parameters the singlino is the lightest neutralino, which modifies the signature for susy particles. Simple analytical approximations are developed that qualitatively explain the numerical results.

Employees' views on outsourcing and its impact on employee turnover: A phenomenological study  

NASA Astrophysics Data System (ADS)

Increasing use of outsourcing gives employees concern about personal job security. Using a modified van Kaam approach, this qualitative phenomenological study examined perceptions and experiences of 12 employees' on the influence outsourcing had on employee turnover. Five themes describing employee perceptions emerged: (a) preparation---education gives job security, (b) plausibility---all believed job loss plausible, (c) emotional influence---feelings of stress, threat, betrayal, and not being valued, (d) environment---value of communication and interaction with leaders, and (e) confidence---gained from increased education, skills, and knowledge protected from outsourcing. Significance of this study to leadership is the identification of employee perceptions of outsourcing and motivating factors influencing employee turnover during times of outsourcing. Findings might present new information and assist leaders with employee retention concerns for future outsourcing activities.

Triggering change in diabetes care delivery in general practice: a qualitative evaluation approach using the clinical microsystem framework  

PubMed Central

Background In 2008, the Sunshine Coast Division of General Practice (SCDGP) in Queensland, Australia initiated a highly successful Improved Diabetes Management (IDM) program with general practices in a regional area. The IDM program was evaluated against the 10 elements of a high functioning clinical microsystem framework as identified by Nelson et al. (2007) in order to determine key factors contributing to the successful adoption and uptake of the program in participating general practices. Methods The evaluation focussed on in-depth key informant interviews with 10 SCDGP staff and general practitioners (GPs) involved in the IDM program. A thematic analysis was undertaken and common emergent themes were reviewed against the 10 elements of high performing clinical microsystem. Results While all aspects of the clinical microsystem approach appeared effective in the design, implementation and adoption of the IDM program, several characteristics were crucial. The identification of champions of change in both the division and participating practices, the celebration of positive achievements and the use ‘real data’ from practices to demonstrate improved health outcomes for patients from the practice were instrumental in motivating participating GPs to both implement and sustain changes in their diabetes care delivery. Conclusion In designing and redesigning health care, the clinical microsystems approach offers a pathway for the effective uptake of innovation in Australian primary health care; a means of integrating structure, process and outcomes of a care framework for reviewing improvements in the health care delivery process and could lead to improvements in patient health outcomes.

The nature and evolution of phenomenological empathy in nursing: an historical treatment.  


This study is an historical analysis of the nature and evolution of phenomenological empathy in nursing covering the period from 1861 through 1981. Nursing archival data were analyzed beginning with the inception of modern American nursing during the Civil War. The categories patient cues, empathy, nursing interventions, and patient responses were applied to the qualitative data. Analysis generated 119 instances of phenomenological empathy. The findings showed that patient cues were not a factor in precipitating nurse empathy, whereas patient responses to nursing interventions showed positive outcomes. A conceptual model of phenomenological empathy comprised of four major constructs and 18 concepts was derived from the archival data. PMID:8179362

PubMed Central

Recently published articles have described criteria to assess qualitative research in the health field in general, but very few articles have delineated qualitative methods to be used in the development of Patient-Reported Outcomes (PROs). In fact, how PROs are developed with subject input through focus groups and interviews has been given relatively short shrift in the PRO literature when compared to the plethora of quantitative articles on the psychometric properties of PROs. If documented at all, most PRO validation articles give little for the reader to evaluate the content validity of the measures and the credibility and trustworthiness of the methods used to develop them. Increasingly, however, scientists and authorities want to be assured that PRO items and scales have meaning and relevance to subjects. This article was developed by an international, interdisciplinary group of psychologists, psychometricians, regulatory experts, a physician, and a sociologist. It presents rigorous and appropriate qualitative research methods for developing PROs with content validity. The approach described combines an overarching phenomenological theoretical framework with grounded theory data collection and analysis methods to yield PRO items and scales that have content validity.

[Phenomenology and psychosomatics].  


By dividing the field of the human, the psyche-soma dualism ended in sectorizing diseases into organic illnesses, and psychic illnesses. Eventually, however, the so-called 'psychosomatic disorders' that, apparently, had broken up such a pattern have been converted to a new corpus pineale just as Descartes would have done. The body is reduced to a mere instrument of psyche, and the subject is reduced to a mere onlooker of illness he or she tries to remove one way or the other. Conversely, phenomenology understands that, first of all, the body is 'the body I am' (Leib): the body is the place for communicating with other people, and the place for performing exchanges with things. It is through the body that the world affects us, and it is by means of the body that we display all our meaning onto the world. In everyday life people are just unaware of their bodies. Whenever anxiety busts out, however, the body makes a massive comeback, giving expression to the complex dialectics of the speaking subject through his or her body. Anxiety pertains to a pre-category order of the body, to the unfathomable depth reason is unable to pierce. At the bottom line of a great majority of psychosomatic disorders there lies an intersubjective anxiety conveying a conflict between the loss of an object and the obstacles thus hindering the personal growth. Reason, as a reflexive conscience is unable to solve the conflict -reason is not even aware of conflict, reason does not even perceive any likely relationship among disorders and such or such situations. The body, as an 'operating intentionality' (Merleau-Ponty), as a pre-reflexive access to the world, as a pathos life experience (Lang), will erupt and see to it that conflict is solved, and conflict-linked anxiety are transformed. Body and its great reason -- as Nietzsche would have said, 1883 -- solves everything its way. PMID:12478310

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


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.

Value co-creation, is an emerging business and innovation paradigm, however, there is not enough clarity on the distinctive characteristics of value co-creation as compared to more traditional value creation approaches. The present paper summarizes the results from an empirically-derived research study focusing on the development of a systematic procedure for the identification of firms that are active in value co-creation. The study is based on a sample 273 firms that were selected for being representative of the breadth of their value co-creation activities. The results include: i) the identification of the key components of value co-creation based on a research methodology using web search and Principal Component Analysis techniques, and ii) the comparison of two different classification techniques identifying the firms with the highest degree of involvement in value co-creation practices. To the best of our knowledge this is the first study using sophisticated data collection techniques to provide a classification of firms according to the degree of their involvement in value co-creation.

Some Surprises and Paradoxes Revealed by Inverse Problem Approach and Notion about Qualitative Solutions of SCHRÖDINGER Equations “IN MIND”  

NASA Astrophysics Data System (ADS)

It was an important examination to give a review talk at the previous Conference on Inverse Quantum Scattering (1996, Lake Balaton) about computer visualization of this science in front of its fathers — creators, B. M. Levitan and V. A. Marchenko. We have achieved a new understanding that the discovered main rules of transformations of a single wave function bump, e.g., for the ground bound states of one dimensional quantum systems are applicable to any state of any potential with arbitrary number of bumps from finite to unlimited ones as scattering states and bound states embedded into continuum. It appeared that we need only to repeat the rule mentally the necessary number of times. That uttermost simplification and unification of physical notion of spectral, scattering and decay control for any potential have got an obligatory praise from B. M. Levitan at the conference and was a mighty stimulus for our further research After that we have written both Russian (2002) and improved English editions of “Submissive Quantum Mechanics. New Status of the Theory in Inverse Problem Approach”1 (appeared at the very end of 2007). This book was written for correction of the present defect in quantum education throughout the world. Recently the quantum IP intuition helped us to discover a new concept of permanent wave resonance with potential spatial oscillations.2 This means the constant wave swinging frequency on the whole energy intervals of spectral forbidden zones destroying physical solutions and deepening the theory of waves in periodic potentials. It also shows the other side of strengthening the fundamentally important magic structures. A ‘new language’ of wave bending will be presented to enrich our quantum intuition, e.g., the paradoxical effective attraction of barriers and repulsion of wells in multichannel systems, etc.

Physiotherapists' experiences of physiotherapy interventions in scientific physiotherapy publications focusing on interventions for children with cerebral palsy: a qualitative phenomenographic approach  

PubMed Central

Background Physiotherapy research concerning interventions for children with CP is often focused on collecting evidence of the superiority of particular therapeutic methods or treatment modalities. Articulating and documenting the use of theory, instrumentation and research design and the assumptions underlying physiotherapy research interventions are important. Physiotherapy interventions focusing on children with Cerebral Palsy should, according to the literature, be based on a functional and environmental perspective with task-specific functional activity, motor learning processes and Family-Centred Service i.e. to enhance motor ability and improve capacity so that the child can perform the tasks necessary to participate actively in everyday life. Thus, it is important to coordinate the norms and values of the physiotherapist with those of the family and child. The aim of this study was to describe how physiotherapists’ experiences physiotherapy interventions for children with CP in scientific physiotherapy publications written by physiotherapists. Methods A qualitative phenomenographic approach was used. Twenty- one scientific articles, found in PubMed, strategically chosen according to year of publication (2001–2009), modality, journals and country, were investigated. Results Three qualitatively different descriptive categories were identified: A: Making it possible a functional-based intervention based on the biopsychosocial health paradigm, and the role of the physiotherapist as collaborative, interacting with the child and family in goal setting, intervention planning and evaluation, B: Making it work an impairment-based intervention built on a mixed health paradigm (biomedical and biopsychosocial), and the role of the physiotherapist as a coach, leading the goal setting, intervention planning and evaluation and instructing family members to carry out physiotherapist directed orders, and; C: Making it normal an impairment-based intervention built on a biomedical health paradigm, and the role of the physiotherapist as an authoritative expert who determine goals, intervention planning and evaluation. Conclusions Different paradigms of health and disability lead to different approaches to physiotherapy which influence the whole intervention process regarding strategies for the assessment and treatment, all of which influence Family-Centred Service and the child’s motor learning strategies. The results may deepen physiotherapists’ understanding of how different paradigms of health influence the way in which various physiotherapy approaches in research seek to solve the challenge of CP.

Topics in Supergravity Phenomenology  

E-print Network

In the first part of the review article, we discuss the possibility of realizing "mu-split-like SUSY" scenario from a phenomenological model, which we show could be realizable locally as the large volume limit of a type IIB Swiss-Cheese Calabi-Yau orientifold involving a mobile space-time filling D3-brane localized at a nearly special Lagrangian three-cycle embedded in the "big" divisor and multiple fluxed stacks of space-time filling D7-branes wrapping the same "big" divisor. We show that the mass of one of the Higgs doublets can be produced to be of the order of 125 GeV whereas other Higgs as well as higgsino mass parameter to be very heavy- the "mu-split-like SUSY" scenario. Then we discuss the role of the heavy squarks/sleptons and the light Higgs in (i) obtaining long-lived gluinos (ii) in verifying that the NLSPs (squarks/sleptons/neutralino) decay into the LSP (gravitino) respects the BBN constraints with the lifetime of the LSP (gravitino) coming out to be of the order or larger than the age of the universe, (iii) getting gravitino relic abundance of around 0.1, and (iv) obtaining electronic EDM close to the experimental upper bounds. In second part of the review article, we obtain local M-theory uplift of Type IIB background involving non-compact (resolved) warped deformed conifold and (N) space time filling D3-branes placed on the singularity of the conifold, (M) D5-branes wrapped around compact 2-sphere, and (N_f) D7-branes wrapped around non-compact four-cycle via Strominger-Yau-Zaslow's mirror symmetry prescription and show the stability of the solution so obtained. We propose a new MQGP limit corresponding to finite-string-coupling (g_s~ 1)- large-t'Hooft-coupling regime of M-theory. Interestingly, we obtain eta/s=1/4 pi for the uplift and the diffusion constant D~1/T for types IIB/IIA backgrounds in the both limits.

Phenomenological studies of dark matter  

NASA Astrophysics Data System (ADS)

It is common knowledge that eighty percent of the matter in our Universe consists of a mysterious substance called "dark matter'' (DM) which has only been detected through its gravitational interactions. The "Standard Model'' (SM) of particle physics, despite its extremely impressive successes, does not have a good candidate particle to fit the DM requirements. If DM is made up of a particle which interacts weakly and it has a mass on the same scale as other SM particles, it should be detectable. In this work, two different phenomenological studies of DM are performed. The first possibility is a weakly-interacting particle being detected when a high density of particles and enough energy is present. These conditions are met by objects called "active galactic nuclei'' (AGN). AGN are the extremely violent central regions of very large galaxies, and in these regions highly-energetic "jets'' of particles are accelerated. It was thought that the possibility the jet particles interact with the surrounding DM producing photons with very distinctive characteristics. A comparison of predicted values with current data is made and it is shown that the prospects for detecting DM in this way are promising in the near future. In the second approach instead of working with complicated fully developed models, only the minimal content needed to account for DM is added to the SM. The strength of these "simplified'' models is that they encompass the interactions and parameter spaces of well-motivated models such as supersymmetry. A simplified model of fermionic DM candidate which couples exclusively to the right handed top quark via a color-charged scalar is considered (motivated by EW symmetry breaking). It is shown that this model can account for the totality of DM and the chances of detection in the near future are very good.

Phenomenologies of ferromagnetism in metals (invited) (abstract)  

NASA Astrophysics Data System (ADS)

Magnetism remains mysterious 100 years after Ewing made his initial models of interacting compasses. Many aspects are seen clearly, but at each step from the spinning electron to the rotor of a motor complexity obscures. At the macroscopic level the difficulties in ferromagnetism start with magnetostatics, which in principle calls for the evaluation of sixfold integrals. At the quantum level one needs fully relativistic spin-polarized calculations that remain beyond the current state of the art in order to have a full description of the ground state of a homogeneous piece of material with periodic boundary conditions. While it is known in principle how to carry out such calculations, in practice an experimentalist relies on phenomenology for the interpretation of data. The role of phenomenology is to create molds into which the experimental data is pressed. Theoretical analyses of critical phenomena are among the triumphs of modern magnetism. The picture is beautiful as long as one ignores anisotropies, dipole-dipole interactions, magnetostriction, and dynamic effects, all of which are the heart of micromagnetics, not to mention imperfections, inhomogeneities, and surface effects. Studies of the response, static and dynamic, of nearly perfect single crystals of Fe, grown from the decomposition of FeCl2 in the form of whiskers, provide examples where the experiments attempt to approach the neatness of the theories. Interpretation of data requires understanding of the dominant magnetostatics, the underlying micromagnetics and the resulting magnetization patterns, and the major role of eddy currents in obscuring intrinsic loss effects. One combines these aspects of Maxwell's equations with parametric formulations of the equation of state and the Landau-Lifshitz equations of motion to extract magnetizations, susceptibilities, anisotropies, and damping parameters as functions of internal fields and frequency. The micromagnetics of the ideally soft ferromagnetic material serves as a foundation for the phenomenology. Fifty years of progress in understanding of phase transitions provides the critical phenomenology. The Landau-Lifshitz equations of motion developed for feromagnetism also describe the dynamic response in the transition from paramagnetism to ferromagnetism when allowance is made for the frequency, field, and temperature dependence of the damping. When the phenomenology and the data are not in full accord it is difficult to assign the source of the misfit. Yet one rejoices in the fact that they fit, sort of.

Objective To explore the psychological consequences of experiencing symptomatic pulmonary embolism (PE). Design Qualitative interview-based study using interpretative phenomenological analysis. Setting Outpatients who attended an anticoagulation clinic in a district general hospital. Participants Patients attending an anticoagulation clinic following hospital admission for symptomatic PE were approached to participate. A total of 9 (4 women, 5 men) of 11 patients approached agreed to be interviewed. Participants were aged between 26 and 72?years and had previously experienced a PE between 9 and 60?months (median=26?months, mean=24?months). Intervention Audiotaped semistructured qualitative interviews were undertaken to explore participants experiences of having a PE and how it had affected their lives since. Data were transcribed and analysed using interpretative phenomenological analysis to identify emergent themes. Results Three major themes with associated subthemes were identified. Participants described having a PE as a life-changing experience comprising initial shock, followed by feeling of loss of self, life-changing decisions and behaviour modification. Features of post-traumatic stress disorder (PTSD) were described with flashbacks, hypervigilance and intrusive thoughts being most prevalent. Participants identified several areas of support needed for such patients including easier access to support through information giving and emotional support. Conclusions Long-term consequences of venous thromboembolism go beyond the physical alone. Patients describe experiencing symptomatic PE to be a life-changing distressing event leading to behaviour modification and in some PTSD. It is likely that earlier psychological intervention may reduce such long-term sequelae. PMID:24694625

Analytical and phenomenological studies of rotating turbulence  

NASA Technical Reports Server (NTRS)

A framework, which combines mathematical analysis, closure theory, and phenomenological treatment, is developed to study the spectral transfer process and reduction of dimensionality in turbulent flows that are subject to rotation. First, we outline a mathematical procedure that is particularly appropriate for problems with two disparate time scales. The approach which is based on the Green's method leads to the Poincare velocity variables and the Poincare transformation when applied to rotating turbulence. The effects of the rotation are now reflected in the modifications to the convolution of a nonlinear term. The Poincare transformed equations are used to obtain a time-dependent analog of the Taylor-Proudman theorem valid in the asymptotic limit when the non-dimensional parameter mu is identical to Omega(t) approaches infinity (Omega is the rotation rate and t is the time). The 'split' of the energy transfer in both direct and inverse directions is established. Secondly, we apply the Eddy-Damped-Quasinormal-Markovian (EDQNM) closure to the Poincare transformed Euler/Navier-Stokes equations. This closure leads to expressions for the spectral energy transfer. In particular, an unique triple velocity decorrelation time is derived with an explicit dependence on the rotation rate. This provides an important input for applying the phenomenological treatment of Zhou. In order to characterize the relative strength of rotation, another non-dimensional number, a spectral Rossby number, which is defined as the ratio of rotation and turbulence time scales, is introduced. Finally, the energy spectrum and the spectral eddy viscosity are deduced.

A qualitative approach to measure the effectiveness of active avian influenza virus surveillance with respect to its cost: a case study from Switzerland.  


The aim of the project was to apply cost-effectiveness analysis to the economic appraisal of avian influenza virus (AIV) surveillance, using the implemented surveillance programme in Switzerland as a case study. First a qualitative risk assessment approach was used to assess the expected impact of surveillance on the transmission and spread of AIV. The effectiveness of surveillance was expressed as the difference in defined probabilities between a scenario with surveillance and a scenario without surveillance. The following probabilities were modelled (i) transmission of highly pathogenic AIV (HPAIV) from wild birds to poultry, (ii) mutation from low pathogenic AIV (LPAIV) into HPAIV in poultry, and (iii) transmission of HPAIV to other poultry holdings given a primary outbreak. The cost-effectiveness ratio was defined conventionally as the difference in surveillance costs (?C) divided by the change in probability (?P), the technical objective, on the presumption that surveillance diminishes the respective probabilities. However, results indicated that surveillance in both wild birds and poultry was not expected to change the probabilities of primary and secondary AIV outbreaks in Switzerland. The overall surveillance costs incurred were estimated at 31,000 €/year, which, to be a rational investment of resources, must still reflect the value policy makers attribute to other benefits from having surveillance (e.g. peace of mind). The advantage of the approach adopted is that it is practical, transparent, and thus able to clarify for policy makers the key variables to be taken into account when evaluating the economic efficiency of resources invested in surveillance, prevention and intervention to exclude AIV.

"They're made in factories and not by witches on the allotment": a qualitative study of midlife women in the united kingdom, exploring their approaches to complementary and alternative medicines.  


This article explores midlife women's experiences and approaches related to complementary and alternative therapies (CAMS). Ninety-six midlife women were asked about their use of CAMs as part of their overall approach to midlife health. Qualitative thematic analysis was combined with a case-based approach. Women set their experience of CAMs in the context of conventional medicine taking and discussed their safety and different uses. For treatments requiring direct contact with a practitioner, accessibility and quality of the relationship were crucial. Four overall approaches could be discerned (political-critical, pragmatic, careful and wellbeing-oriented) that dynamically interacted with women's experiences. PMID:22087594

Building phenomenological models of complex biological processes  

NASA Astrophysics Data System (ADS)

A central goal of any modeling effort is to make predictions regarding experimental conditions that have not yet been observed. Overly simple models will not be able to fit the original data well, but overly complex models are likely to overfit the data and thus produce bad predictions. Modern quantitative biology modeling efforts often err on the complexity side of this balance, using myriads of microscopic biochemical reaction processes with a priori unknown kinetic parameters to model relatively simple biological phenomena. In this work, we show how Bayesian model selection (which is mathematically similar to low temperature expansion in statistical physics) can be used to build coarse-grained, phenomenological models of complex dynamical biological processes, which have better predictive powers than microscopically correct, but poorely constrained mechanistic molecular models. We illustrate this on the example of a multiply-modifiable protein molecule, which is a simplified description of multiple biological systems, such as an immune receptors and an RNA polymerase complex. Our approach is similar in spirit to the phenomenological Landau expansion for the free energy in the theory of critical phenomena.

Overseas trained nurses' perception of UK nurses' caring attitudes: a qualitative study.  


The aim of this study was to explore overseas nurses' perception of their nursing colleagues' caring attitudes in the National Health Service (NHS) in the UK. A qualitative phenomenological approach using semi-structured interviews was used to obtain data from 12 overseas nurses. The interview transcripts were transcribed verbatim and analysed using van Manen thematic approach. Although many themes emerged following thematic analysis, this study will report the findings of three themes such as empathy, understanding and caring perspectives, emotional impact and lack of teamwork. In conclusion, this study provides an insight and it increases our understanding of overseas nurses' perceptions of their nursing colleagues' caring attitudes in the NHS in the UK. This paper concludes by indicating that teamwork, being empathetic, understanding and reducing emotional labour for overseas nurses could lead to a more satisfied working environment for overseas nurses in the NHS in the UK.

Phenomenology from the Landscape of String Vacua  

E-print Network

This article is the author's PhD thesis. After a review of string vacua obtained through compactification (with and wothout fluxes), it presents and describes various aspects of the Landscape of string vacua. At first it gives an introduction and an overview of the statistical study of the set of four dimensional string vacua, giving the detailed study of one corner of this set (G2-holonomy compactifications of M-theory). Then it presents the ten dimensional approach to string vacua, concentrating on the ten dimensional description of the Type IIA flux vacua. Finally it gives two examples of models having some interesting and characteristic phenomenological features, and that belong to two different corners of the Landscape: warped compactifications of Type IIB String Theory and M-theory compactifications on G2-holonomy manifolds.

Scaling Phenomenology in Meson Photoproduction from CLAS  

SciTech Connect

In the high energy limit, perturbative QCD predicts that hard scattering amplitudes should follow simple scaling laws. For hard scattering at 90 deg., we show that experiments support this prediction even in the ''medium energy'' regime of 2.3 GeV{<=}{radical}(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 (p{omega}, p{eta}, p{eta}', K{sup +{Lambda}}and K{sup +{Sigma}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 negative integers. We demonstrate the application of saturated Regge phenomenology by performing a partial wave analysis fit to the {gamma}yp{yields}p{eta}'differential cross sections.

The Arizona Source Phenomenology Experiments (SPE) have resulted in an important dataset for the nuclear monitoring community. The 19 dedicated single-fired explosions and multiple delay-fired mining explosions were recorded by one of the most densely instrumented accelerometer and seismometer arrays ever fielded, and the data have already proven useful in quantifying confinement and excitation effects for the sources. It is very interesting to note that we have observed differences in the phenomenology of these two series of explosions resulting from the differences between the relatively slow (limestone) and fast (granodiorite) media. We observed differences at the two SPE sites in the way the rock failed during the explosions, how the S-waves were generated, and the amplitude behavior as a function of confinement. Our consortium's goal is to use the synergy of the multiple datasets collected during this experiment to unravel the phenomenological differences between the two emplacement media. The data suggest that the main difference between single-fired chemical and delay-fired mining explosion seismograms at regional distances is the increased surface wave energy for the latter source type. The effect of the delay-firing is to decrease the high-frequency P-wave amplitudes while increasing the surface wave energy because of the longer source duration and spall components. The results suggest that the single-fired explosions are surrogates for nuclear explosions in higher frequency bands (e.g., 6-8 Hz Pg/Lg discriminants). We have shown that the SPE shots, together with the mining explosions, are efficient sources of S-wave energy, and our next research stage is to postulate the possible sources contributing to the shear-wave energy.

Turbulent Friction in Rough Pipes and the Energy Spectrum of the Phenomenological Theory  

E-print Network

The classical experiments on turbulent friction in rough pipes were performed by J. Nikuradse in the 1930's. Seventy years later, they continue to defy theory. Here we model Nikuradse's experiments using the phenomenological theory of Kolmog\\'orov, a theory that is widely thought to be applicable only to highly idealized flows. Our results include both the empirical scalings of Blasius and Strickler, and are otherwise in minute qualitative agreement with the experiments; they suggest that the phenomenological theory may be relevant to other flows of practical interest; and they unveil the existence of close ties between two milestones of experimental and theoretical turbulence.

Perceptual Anomalies in Schizophrenia: Integrating Phenomenology and Cognitive Neuroscience  

PubMed Central

From phenomenological and experimental perspectives, research in schizophrenia has emphasized deficits in “higher” cognitive functions, including attention, executive function, as well as memory. In contrast, general consensus has viewed dysfunctions in basic perceptual processes to be relatively unimportant in the explanation of more complex aspects of the disorder, including changes in self-experience and the development of symptoms such as delusions. We present evidence from phenomenology and cognitive neuroscience that changes in the perceptual field in schizophrenia may represent a core impairment. After introducing the phenomenological approach to perception (Husserl, the Gestalt School), we discuss the views of Paul Matussek, Klaus Conrad, Ludwig Binswanger, and Wolfgang Blankenburg on perception in schizophrenia. These 4 psychiatrists describe changes in perception and automatic processes that are related to the altered experience of self. The altered self-experience, in turn, may be responsible for the emergence of delusions. The phenomenological data are compatible with current research that conceptualizes dysfunctions in perceptual processing as a deficit in the ability to combine stimulus elements into coherent object representations. Relationships of deficits in perceptual organization to cognitive and social dysfunction as well as the possible neurobiological mechanisms are discussed. PMID:17118973

Caring between nursing students and physically/mentally handicapped children: a phenomenological study.  


Advanced technology has increased the life expectancy to age 20 for most chronically ill children. Consequently, nurses will be encountering an increasing number of physically and mentally handicapped children. Nursing students' discovery of the meaning of caring with exceptional children will help prepare them for interactions with these special children during their nursing careers. A phenomenological study was undertaken to explore 36 nursing students' caring experiences with physically and mentally handicapped children. Van Kaam's phenomenological methodology was used to analyze the data. Sharing the findings of this phenomenological study with nursing students is one approach faculty can use to help reduce their anxiety regarding upcoming clinical rotations with exceptional children.

Dynamics-generating semigroups and phenomenology of decoherence  

E-print Network

The earlier proposed Dynamics-Generating Approach (DGA) is reviewed and extended. Starting from an arbitrarily chosen group or semigroup which have structure similar to the structure of Galilei group, DGA allows one to construct phenomenological description of dynamics of the corresponding "elementary quantum object" (a particle or non-local object of special type). A class of Galilei-type semigroups, with semigroup of trajectories (parametrized paths) instead of translations, allows one to derive Feynman path integrals in the framework of DGA. The measure of path integrating (exponential of the classic action) is not postulated but derived from the structure of projective semigroup representations. The generalization of DGA suggested in the present paper allows one to derive dynamics of open quantum systems. Specifically, phenomenological description of decoherence and dissipation of a non-relativistic particle is derived from Galilei semigroup.

The anatomy of sorrow: a spiritual, phenomenological, and neurological perspective  

PubMed Central

There is considerable controversy, both within and outside the field of psychiatry, regarding the boundaries of normal sadness and clinical depression. Furthermore, while there are frequent calls for a "pluralistic", comprehensive approach to understanding depression, few writers have tried to integrate insights from the spiritual, philosophical, and neurobiological literature. The author proposes that such a synthesis is possible, and that our understanding of ordinary sorrow and clinical depression is enriched by drawing from these disparate sources. In particular, a phenomenological analysis of sorrow and depression reveals two overlapping but distinct "lifeworlds". These differ in the relational, temporal, dialectical, and intentional realms. Recent brain imaging studies are also beginning to reveal the neurobiological correlates of sorrow and depression. As we come to understand the neurobiology of these states, we may be able to correlate specific alterations in "neurocircuitry" with their phenomenological expressions. PMID:18559111

The working experiences of novice psychiatric nurses in Taiwanese culture: a phenomenological study.  


Novice psychiatric nurses experience heavy workloads, insufficient training and support in Taiwan. The aim of this study was to understand the working experiences of novice psychiatric nurses during their first year in a clinical setting. A qualitative phenomenological approach, using semi-structured face-to-face interviews was used. Narratives were analyzed using Colaizzi's seven-step method. Data saturation was reached after interviews were conducted with 15 nurses based on the purposive sampling. Four themes and eight sub-themes were identified: struggling (lacking a sense of security and competency), emulating (learning the process of interaction with clients and families, learning an appropriate role from nursing staff), prevailing (developing core competency, creating a therapeutic environment) and belonging (coping with the job, becoming a part of the psychiatric nursing staff). The findings from this study demonstrate that nurses are often inadequately prepared for psychiatric nursing. They have little understanding of mental illness, are unable to communicate appropriately with clients and struggle to cope with the conditions. Our study supports the importance for helping nurses to improve their essential knowledge and skills for coping with the job and providing good quality care, particularly in the first year.

Iranian nurses' experiences of brain dead donors care in intensive care units: A phenomenological study  

PubMed Central

Background: Care of brain dead donors is complex, critical, and sensitive and has a direct and positive impact on the end result of organ and tissue transplantation process. This study describes the nurses’ experiences of care of brain dead donors in intensive care units (ICU). Materials and Methods: This research was performed by phenomenological method that is a qualitative approach. Purposive sampling was used to gather the data. The researcher reached to data saturation by deep interviews conducted with eight participants from ICU nurses in Isfahan hospitals who cooperated in care of brain dead donors. Data analysis was performed according to Colaizzi analysis method. Results: Interviews were analyzed and the results of analysis led to “Excruciating tasks” as the main theme formed by psychological effects of facing the situation, heavy and stressful care, defect of scientific knowledge, conflict between feeling and duty, outcome of attitude change in behavior, emotional responses to perceived psychological afflictions, doubt to medical diagnosis, spiritual perceptions, and biological responses when faced with the situation. Conclusion: Caring of brain dead organ donors is difficult and stressful for intensive care nurses and can be a threat for nurses’ health and quality of nursing care. So, providing suitable physical, mental, and working conditions is necessary to make suitable background to maintain and increase nurses’ health and quality of care and effective cooperation of this group of health professionals in organ procurement process.

Qualitative Analysis of the Helical Electronic Energy of Inherently Chiral Calix[4]arenes: An Approach to Effectively Assign Their Absolute Configuration  

PubMed Central

For all microhelices on aromatic rings of inherently chiral calix[4]arene, an expression was derived from one approximation and one hypothesis on the basis of the electron-on-a-helix model of Tinoco and Woody as follows: , where µ = 1 for the right-handed microhelix and µ = ?1 for the left-handed microhelix; and H and K are constant and greater than zero. The expression correlates microhelical electronic energy (E) with the atom polarizability difference (??) on both microhelix ends, which intuitively and clearly shows the impact of helical substituent polarizability on helical electronic energy. The case analysis almost entirely proves that the qualitative analysis of the helical electronic energy of inherently chiral Calix[4]arenes with the expression is scientific and can be used to effectively assign their absolute configuration.

Harnessing psychoanalytical methods for a phenomenological neuroscience  

PubMed Central

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.

At first we investigate in detail the ??SSM with one generation of singlets, which can explain all neutrino data, once 1-loop corrections are taken into account. Then we study variations of the model with more singlets, which can generate all neutrino masses and mixings at tree-level. We calculate the decay properties of the lightest supersymmetric particle, assumed to be the lightest neutralino, taking into account all possible final states. The parameter regions where the LSP decays within the LHC detectors but with a length large enough to show a displaced vertex are identified. Decay branching ratios of certain final states show characteristic correlations with the measured neutrino angles, allowing to test the model at the LHC. Finally we briefly discuss possible signatures, which allow to distinguish between different R-parity breaking models.

Phenomenology of the CAH+ measure  

E-print Network

The CAH+ measure regulates the infinite spacetime volume of the multiverse by constructing a surface of constant comoving apparent horizon (CAH) and then removing the future lightcones of all points on that surface (the latter prescription is referred to by the "+" in the name of the measure). This measure was motivated by the conjectured duality between the bulk of the multiverse and its future infinity and by the causality condition, requiring that the cutoff surfaces of the measure should be spacelike or null. Here we investigate the phenomenology of the CAH+ measure and find that it does not suffer from any known pathologies. The distribution for the cosmological constant Lambda derived from this measure is in a good agreement with the observed value, and the distribution for the number of inflationary e-foldings satisfies the observational constraint. The CAH+ measure does not exhibit any "runaway" behaviors at zero or negative values of Lambda, which have been recently shown to afflict a number of other measures.

Phenomenological theory of echo poles  

NASA Astrophysics Data System (ADS)

In scattering theory the effect associated with the downward crossing of the phase-shift ??(k) (? being the orbital angular momentum and k the momentum) through ??=?/2 (mod ?) is called echo. In the standard nuclear theory (Breit-Wigner theory) the echo is described and evaluated in terms of scattering by an impenetrable sphere. However, this model holds only at sufficiently high energy, while it is inadequate at low energy. In this paper we show that the echo effect can be associated with two different regimes acting at low and high energy, respectively. At high energy the hard-sphere scattering model seems to describe appropriately the phenomenon. At low energy we propose a mechanism due to the exchange forces induced by the Pauli exclusion principle in the fermionic interaction, which leads to nonlocal potentials. These potentials admit for the scattering amplitude pole singularities in the fourth quadrant of the complex angular momentum plane. This paper analyzes the role played by this class of poles in the description of the low energy regime of echoes. A specific phenomenological analysis is performed, taking as typical example the ?-? elastic scattering.

"Caring for insiderness": Phenomenologically informed insights that can guide practice  

PubMed Central

Understanding the “insider” perspective has been a pivotal strength of qualitative research. Further than this, within the more applied fields in which the human activity of “caring” takes place, such understanding of “what it is like” for people from within their lifeworlds has also been acknowledged as the foundational starting point in order for “care” to be caring. But we believe that more attention needs to be paid to this foundational generic phenomenon: what it means to understand the “insiderness” of another, but more importantly, how to act on this in caring ways. We call this human phenomenon “caring for insiderness.” Drawing on existing phenomenological studies of marginal caring situations at the limits of caring capability, and through a process of phenomenologically oriented reflection, we interrogated some existential themes implicit in these publications that could lead to deeper insights for both theoretical and applied purposes. The paper provides direction for practices of caring by highlighting some dangers as well as some remedies along this path. PMID:24461568

A phenomenological finite element model of stereolithography processing  

SciTech Connect

In the stereolithography process, three dimensional parts are built layer by layer using a laser to selectively cure slices of a photocurable resin, one on top of another. As the laser spot passes over the surface of the resin, the ensuing chemical reaction causes the resin to shrink and stiffen during solidification. When laser paths cross or when new layers are cured on top of existing layers, residual stresses are generated as the cure shrinkage of the freshly gelled resin is constrained by the adjoining previously-cured material. These internal stresses can cause curling in the compliant material. A capability for performing finite element analyses of the stereolithography process has been developed. Although no attempt has been made to incorporate all the physics of the process, a numerical platform suitable for such development has been established. A methodology and code architecture have been structured to allow finite elements to be birthed (activated) according to a prescribed order mimicking the procedure by which a laser is used to cure and build-up surface layers of resin to construct a three dimensional geometry. In its present form, the finite element code incorporates a simple phenomenological viscoelastic material model of solidification that is based on the shrinkage and relaxation observed following isolated, uncoupled laser exposures. The phenomenological material model has been used to analyze the curl in a simple cantilever beam and to make qualitative distinctions between two contrived build styles.

Toward a phenomenology of trance logic in posttraumatic stress disorder.  


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. PMID:15154197

Phenomenology of genius and psychopathology.  


The relationship between genius and madness has been a subject of interest since the beginning of critical and philosophical thinking. Thus, Aristotle, in the Book XXX of the Problemata, asks himself "why are all extraordinary men in the fields of philosophy, politics, poetry and art melancholic?, adding afterwards: "...and some of them in such a way that they may suffer from pathologic manifestations whose origin is in the black bile". In the past decades the German author Tellenbach studied the personalities of several geniuses, both from fiction, such as Hamlet, and from reality, such as the writer von Kleist, concluding that they suffered from a specific form of depression that he called "Schwermut" (melancholy), which was supposedly different from the narrowly defined illness of depression. Other work done on this subject is the extensive study by the North American author Kay Jamison, who, after researching the biography and the tree of a long list of writers, composers and musicians, concluded that all of them had suffered to some degree from a bipolar disorder. This author strives to carry out a phenomenology of genius, and he finds that, together with other essential features, the geniuses always show forms of experiencing and/or of behaving which do not fall within the range that is considered normal, although they can not always be classified as pathological. His study is based on the analysis of the life and the work of three men whose genius could not be doubted: the naturalist Alexander von Humboldt, the philosopher Soeren Kierkegaard and the poet Rainer Maria Rilke. This author specially focuses on the last named, since in his later work he explicitly meditated on the suffering that has meant for him his condition of genius and what he considered the only way to overcome them: to be faithful to the work of art, whose fulfilment was imposed on him--to a certain degree from the endogenous--as an unavoidable imperative.

A transpersonal approach to care: a qualitative study of performers' experiences with DooR to DooR, a hospital-based arts program.  


The arts have a history of relaxing and calming patients in the hospital setting, yet research is limited on how arts may aid in the healing process. DooR to DooR was established to bring comfort, respite, and healing to hospitalized patients, family members, and health care staff. DooR to DooR is located in the University of North Carolina Hospitals at Chapel Hill, North Carolina; professional performing artists visit there, spending 5 to 10 minutes with each patient, family member, and health care staff. The purpose of this qualitative study is to understand performers' experiences and of how arts-based programs can facilitate improved patient outcomes in the hospitalized setting to help nurses better use the arts in their care of patients and families. Three overarching themes were identified: (a) the arts are therapeutic for all involved, (b) the arts transform the hospital environment, and (c) nurses and the other medical staff play an important role. The significance of this study for nursing practice is that the arts are a plausible intervention for the hospital because they may help improve patient outcomes by reducing pain and depression and by relieving stress among staff and family members. More research is needed to determine the level of arts-as-an-intervention knowledge among nurses. PMID:24176898

Postmaterialism, new environmental paradigm and ecocentric approach: A qualitative and quantitative study of environmental attitudes of Turkish senior high school students  

NASA Astrophysics Data System (ADS)

The present study aims to elucidate the determinant factors that affect environmental attitudes (EA) of senior high school students in Turkey and the origins of these EAs. Over nine hundred students from different school types, neighborhoods, geographical regions, social-economic backgrounds participated in the questionnaire based surveys which are called the New Environmental Paradigm (NEP) and the General Attitudes and Perceptions (GAP), and twenty of those students were interviewed as well. Survey results show that EAs of students vary depending on school type, gender, parents' education levels and professions, and household income. Normal public high school students, females, lower-middle class students, students with well educated parents in white collar professions, and student with liberal parents have more pro-environmental attitudes than the others. With regard to school type, students from public technical high school (vocational school), almost all of which are based on single-sex education, have scored the lowest on both surveys which are the NEP and the GAP. The results from the qualitative portion are as follows: Students' perceptions about the environment and related issues are limited to their local habitat. Although the mean scores of students on both surveys do not differ to a statistically significant extent depending on geographical regions, interviews show that participants from different regions have distinct priorities, which range from poverty to sea pollution. Even though students' first priority in their lives is education, education is perceived as a mechanism to achieve a more prosperous life rather than an end in itself. Almost all interview participants agree on the importance of education in shaping EAs. Interestingly, some interviewees (four out of ten males) also comment that a man's sense of his own masculinity can be threatened when confronted by another man to change his attitude towards the environment.

Sampling in Qualitative Research  

PubMed Central

In gerontology the most recognized and elaborate discourse about sampling is generally thought to be in quantitative research associated with survey research and medical research. But sampling has long been a central concern in the social and humanistic inquiry, albeit in a different guise suited to the different goals. There is a need for more explicit discussion of qualitative sampling issues. This article will outline the guiding principles and rationales, features, and practices of sampling in qualitative research. It then describes common questions about sampling in qualitative research. In conclusion it proposes the concept of qualitative clarity as a set of principles (analogous to statistical power) to guide assessments of qualitative sampling in a particular study or proposal.

Qualitative data analysis: conceptual and practical considerations.  


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

Qualitative methods in environmental health research.  

PubMed Central

Public health researchers increasingly turn to qualitative methods either on their own or in combination with quantitative methods. Qualitative methods are especially important to community environmental health research, as they provide a way to produce community narratives that give voice to individuals and characterize the community in a full and complex fashion. This article first traces the legacy of qualitative research in environmental health, then uses a case study of the author's experiences studying the Woburn, Massachusetts, childhood leukemia cluster to provide personal and scholarly insights on qualitative approaches. That material then informs a discussion of important components of qualitative methods in environmental health research, including flexible study design, access, trust, empathy, and personal shifts in the researcher's worldview, bias, and the nature of the researcher's roles. A concluding discussion addresses issues in funding policy and research practices. PMID:14594634

What's in a name? Qualitative description revisited.  


"Whatever Happened to Qualitative Description?" (Sandelowski, 2000) was written to critique the prevailing tendency in qualitative health research to claim the use of methods that were not actually used and to clarify a methodological approach rarely identified as a distinctive method. The article has generated several misconceptions, most notably that qualitative description requires no interpretation of data. At the root of these misconceptions is the persistent challenge of defining qualitative research methods. Qualitative description is a "distributed residual category" (Bowker & Star, 2000). Cambridge, MA: The MIT Press) in the classification of these methods. Its value lies not only in the knowledge its use can produce, but also as a vehicle for presenting and treating research methods as living entities that resist simple classification. PMID:20014004

Collider Phenomenology of Extra Dimensions  

SciTech Connect

In recent years there has been much interest in the possibility that there exist more spacetime dimensions than the usual four. Models of particle physics beyond the Standard Model that incorporate these extra dimensions can solve the gauge hierarchy problem and explain why the fermion masses a spread over many orders of magnitude. In this thesis we explore several possibilities for models with extra dimensions. First we examine constraints on the proposal of Arkani-Hamed and Schmaltz that the Standard Model fermions are localized to different positions in an extra dimension, thereby generating the hierarchy in fermion masses. We find strong constraints on the compactification scale of such models arising from flavor-changing neutral currents. Next we investigate the phenomenology of the Randall-Sundrum model, where the hierarchy between the electroweak and Planck scales is generated by the warping in a five-dimensional anti-de Sitter space. In particular, we investigate the ''Higgsless'' model of electroweak symmetry breaking due to Csaki et. al., where the Higgs has been decoupled from the spectrum by taking its vacuum expectation value to infinity. We find that this model produces many distinctive features at the LHC. However, we also find that it is strongly constrained by precision electroweak observables and the requirement that gauge-boson scattering be perturbative. We then examine the model with a finite vacuum expectation value, and find that there are observable shifts to the Higgs scalar properties. Finally, in the original large extra dimension scenario of Arkani-Hamed, Dimopoulos, and Dvali, the hierarchy problem is solved by allowing gravity to propagate in a large extra dimensional volume, while the Standard Model fields are confined to 4 dimensions. We consider the case where there are a large number of extra dimensions (n {approx} 20). This model can solve the hierarchy problem without introducing a exponentially large radii for the extra dimensions, and represents a scenario that is difficult to obtain in string theory. We show that, if this scenario holds, the number of dimensions can be constrained to be larger than the number predicted by critical string theory. Searching for signals of many dimensions is then an important test of whether string theory is a good description of quantum gravity.

It is obtained in a non-relativistic approach and in the limit of a short ranged hadronic interaction to terms of order ?2log? using an extended charge distribution. A hadronic ?N scattering length ah?-p=0.0870(5)m?-1 is deduced leading to a ?NN coupling constant from the GMO relation gc2/(4?)=14.04(17).

This article is aimed to present a new approach to clinical research and also to clinical work based on Grounded Theory and on the software developed from it, Atlas.ti. It includes two practical applications of this software, one is the analysis of a clinical interview and the other the assessment of nine interviews taken with the Five Minutes Speech Sample belonging to five couples of parents. As it is presented below, each analysis was performed as a circular process, starting from the data, grouping them into categories, creating codes and then returning to the data in order to sustain them and to establish relations between them. In our view, this is a new and interesting way of approaching clinical data which gives the clinician the possibility of developing a deeper understanding of the patient/client without loosing himelf/herself in the theories of the psychological orientation the psychotherapist belongs to.

Impact of a nationwide study for surveillance of maternal near-miss on the quality of care provided by participating centers: a quantitative and qualitative approach  

PubMed Central

Background The Brazilian Network for Surveillance of Severe Maternal Morbidity was established in 27 centers in different regions of Brazil to investigate the frequency of severe maternal morbidity (near-miss and potentially life-threatening conditions) and associated factors, and to create a collaborative network for studies on perinatal health. It also allowed interventions aimed at improving the quality of care in the participating institutions. The objective of this study was to evaluate the perception of the professionals involved regarding the effect of participating in such network on the quality of care provided to women. Methods A mixed quantitative and qualitative study interviewed coordinators, investigators and managers from all the 27 obstetric units that had participated in the network. Following verbal informed consent, data were collected six and twelve months after the surveillance period using structured and semi-structured interviews that were conducted by telephone and recorded. A descriptive analysis for the quantitative and categorical data, and a thematic content analysis for the answers to the open questions were performed. Results The vast majority (93%) of interviewees considered it was important to have participated in the network and 95% that their ability to identify cases of severe maternal morbidity had improved. They also considered that the study had a positive effect, leading to changes in how cases were identified, better organization/standardization of team activities, changes in routines/protocols, implementation of auditing for severe cases, dissemination of knowledge at local/regional level and a contribution to local and/or national identification of maternal morbidity. After 12 months, interviewees mentioned the need to improve prenatal care and the scientific importance of the results. Some believed that there had been little or no impact due to the poor dissemination of information and the resistance of professionals to change practice. In this second interview, a lack of systematic surveillance after the end of the study, difficulty in referring cases and changes in the leadership of the unit were mentioned. Conclusion In the opinion of these professionals, participating in a network for the surveillance of severe maternal morbidity represented a good strategy for improving services, even in reference centers.

Qualitative models for planning: A gentle introduction  

NASA Technical Reports Server (NTRS)

Qualitative modeling is the study of how the physical world behaves. These physical models accept partial descriptions of the world and output the possible changes. Current systems assume that the model is static and that physical entities do not effect change into the world. An approach to planning in physical domains and a working implementation which integrates qualitative models with a temporal interval-based planner are described. The planner constructs plans involving physical qualities and their behavioral descriptions.

Qualitative methods in research on teaching  

NSDL National Science Digital Library

Basic issues concerning interpretive research, and theories and methods of using interpretive research to study teaching are discussed. The concept of interpretive research may also be known as ethnographic, qualitative, participant observational, case study, symbolic interactionist, phenomenological, or constructivist. Interpretive research studies the meaning of actions that occur, both in face-to-face interactions and in the wider society surrounding the immediate scene of action. To conduct interpretive research on teaching, intense and long-term participant observation in an educational setting is required, followed by deliberate and long-term reflection on what was observed. Questions regarding the observer's point of view, previously learned formal theories, cultural conditioning, and personal values must be considered. Attitudes toward teaching and learning as well as measures of effectiveness are also worth examining. This paper argues that such detailed scrutiny of everyday teaching routines is a route to improving educational practice, as performed by university researchers as well as practicing teachers.

Is Europe putting theory into practice? A qualitative study of the level of self-management support in chronic care management approaches  

PubMed Central

Background Self-management support is a key component of effective chronic care management, yet in practice appears to be the least implemented and most challenging. This study explores whether and how self-management support is integrated into chronic care approaches in 13 European countries. In addition, it investigates the level of and barriers to implementation of support strategies in health care practice. Methods We conducted a review among the 13 participating countries, based on a common data template informed by the Chronic Care Model. Key informants presented a sample of representative chronic care approaches and related self-management support strategies. The cross-country review was complemented by a Dutch case study of health professionals’ views on the implementation of self-management support in practice. Results Self-management support for chronically ill patients remains relatively underdeveloped in Europe. Similarities between countries exist mostly in involved providers (nurses) and settings (primary care). Differences prevail in mode and format of support, and materials used. Support activities focus primarily on patients’ medical and behavioral management, and less on emotional management. According to Dutch providers, self-management support is not (yet) an integral part of daily practice; implementation is hampered by barriers related to, among others, funding, IT and medical culture. Conclusions Although collaborative care for chronic conditions is becoming more important in European health systems, adequate self-management support for patients with chronic disease is far from accomplished in most countries. There is a need for better understanding of how we can encourage both patients and health care providers to engage in productive interactions in daily chronic care practice, which can improve health and social outcomes.

Warped phenomenology in the holographic basis  

SciTech Connect

The holographic basis is a novel tool which allows for a quantitative description of elementary/composite mixing in holographic duals of warped models. We apply this tool to bulk fermions in a slice of AdS{sub 5} and determine the precise admixture of elementary source field and composite resonances forming the standard model fermions. In particular, for the phenomenologically important case of an IR localized right-handed top quark, we show that the massless eigenstate is approximately a 50/50 elementary-composite admixture. We also translate, in a simple yet quantitative manner, several of the phenomenological successes enjoyed by warped models to the language of partial compositeness.

Ethical challenges embedded in qualitative research interviews with close relatives.  


Nurse researchers engaged in qualitative interviews with patients and spouses in healthcare may often experience being in unforeseen ethical dilemmas. Researchers are guided by the bioethical principles of justice, beneficence, non-maleficence, respect for human rights and respect for autonomy through the entire research process. However, these principles are not sufficient to prepare researchers for unanticipated ethical dilemmas related to qualitative research interviews. We describe and discuss ethically challenging and difficult moments embedded in two cases from our own phenomenological interview studies. We argue that qualitative interviews involve navigation between being guided by bioethics as a researcher, being a therapist/nurse and being a fellow human being or even a friend. The researchers' premises to react to unexpected situations and act in a sound ethical manner must be enhanced, and there is a need for an increased focus on the researchers' ethical preparation and to continually address and discuss cases from their own interviews.

The Influence of Practice Standards on Massage Therapists' Work Experience: A Phenomenological Pilot Study  

PubMed Central

This original research is framed in phenomenological methodology, based on interviews conducted and interpreted using qualitative research methods. The findings suggest that, because of both direct and indirect factors (such as the nebulous nature of the work, general isolation in work conditions, and physical concerns), massage therapists perform their work with multiple sources of ambiguity that are potentially anxiety-causing. Licensing offers potential relief for this anxiety, but also generates a new set of frustrations and work concerns. The new concerns include the potential that practice will change to adapt to non-relevant standards and the difficulty of defining a body of work that frequently defies a “one size fits all” categorization. This pilot study suggests several areas for further exploration and also demonstrates the generativity of phenomenological methodology for research related to massage therapy. PMID:21589709

Student experiences in an integrated science course: A phenomenological study  

NASA Astrophysics Data System (ADS)

The purpose of conducting this study was to describe the experiences of average to high-achieving, middle-income students in a newly implemented integrated science course at a Midwest inner-city high school. The focus of this study was to describe the meaning students ascribed to their experiences in this non-tracked, two-year science course, in which many of the suggestions made by science reform efforts were implemented. A phenomenological approach was used in order to develop a holistic picture of the student participants' experiences. Data collection was confined to interviewing, observing, and analyzing the journals of four middle-income, average to high-achieving students enrolled in the same class during the 1994-95 school year. The data were subjective perceptions of the students in their learning environment. A modified version of the Colaizzi method of analysis of phenomenological data was used. This design utilized the Epoche, Phenomenological Reduction, Imaginative Variation and Synthesis. Co-researchers' statements were clustered into horizons of meaning and organized into themes. The textural themes included curriculum, instruction, teachers, peers, and overall impressions. Relationships to time and interactions with peers and teachers were among the structural themes. From these themes, individual and composite textual descriptions were developed. With the addition of the structural components, an integrated composite textual-structural description of the students' experience in the integrated science course resulted. This final product captured the meanings and essences of their experience. This study adds to the scholarly literature and research as it relates to the implementation of progressive pedagogy and theory regarding student experiences in a science course. It will improve educational practice by helping educators make informed decisions regarding curriculum reform, instructional practices, and classroom environment. This study will also improve educational practice by increasing educators' understanding of student experiences in integrated science settings. This study will help improve science education policy by providing an example of the response of students to a type of educational innovation.

Empathy and alteration: the ethical relevance of a phenomenological species concept.  


The debate over the ethics of radically, technologically altering the capacities and traditional form of the human body is rife with appeals to and dismissals of the importance of the integrity of the human species. Species-integrist arguments can be found in authors as varied as Annas, Fukuyama, Habermas, and Agar. However, the ethical salience of species integrity is widely contested by authors such as Buchanan, Daniels, Fenton, and Juengst. This article proposes a Phenomenological approach to the question of species-integrity, arguing in favor of a phenomenon of species-recognition that carries an ethical pull. Building on Husserl's Phenomenological account of empathy and the lived-body, as well as Schopenhauer's concept of compassion as an ethical urphenomenon, I develop a "Phenomenological species concept" (PSC), which I argue has the ethical significance that biological species concepts do not. The PSC reorients the debate over human alteration and species integrity. PMID:25223413

TB infection prevention and control experiences of South African nurses - a phenomenological study  

PubMed Central

Background The tuberculosis (TB) epidemic in South Africa is characterised by one of the highest levels of TB/HIV co-infection and growing multidrug-resistant TB worldwide. Hospitals play a central role in the management of TB. We investigated nurses' experiences of factors influencing TB infection prevention and control (IPC) practices to identify risks associated with potential nosocomial transmission. Methods The qualitative study employed a phenomenological approach, using semi-structured interviews with a quota sample of 20 nurses in a large tertiary academic hospital in Cape Town, South Africa. The data was subjected to thematic analysis. Results Nurses expressed concerns about the possible risk of TB transmission to both patients and staff. Factors influencing TB-IPC, and increasing the potential risk of nosocomial transmission, emerged in interconnected overarching themes. Influences related to the healthcare system included suboptimal IPC provision such as the lack of isolation facilities and personal protective equipment, and the lack of a TB-IPC policy. Further influences included inadequate TB training for staff and patients, communication barriers owing to cultural and linguistic differences between staff and patients, the excessive workload of nurses, and a sense of duty of care. Influences related to wider contextual conditions included TB concerns and stigma, and the role of traditional healers. Influences related to patient behaviour included late uptake of hospital care owing to poverty and the use of traditional medicine, and poor adherence to IPC measures by patients, family members and carers. Conclusions Several interconnected influences related to the healthcare system, wider contextual conditions and patient behavior could increase the potential risk of nosocomial TB transmission at hospital level. There is an urgent need for the implementation and evaluation of a comprehensive contextually appropriate TB IPC policy with the setting and auditing of standards for IPC provision and practice, adequate TB training for both staff and patients, and the establishment of a cross-cultural communication strategy, including rapid access to interpreters.

An interpretative phenomenological analysis of African Caribbean women's experiences and management of emotional distress.  


African Caribbean women are under-represented within mental health services in the United Kingdom, despite sociocontextual vulnerabilities which may increase emotional distress. This qualitative study aimed to explore individual explanatory models of experiences of distress, coping and help-seeking choices, with a view to improving cultural relevance of services. Participants were recruited following their self-referral to self-help community wellbeing workshops. Interpretative phenomenological analysis was carried out following semi-structured interviews with seven African Caribbean women in central London, who reported previously experiencing emotional distress. The study was conducted during 2009. Five super-ordinate themes emerged from the data: explanations of distress, experiences of distress, managing distress, social and cultural influences and seeking help. Each super-ordinate theme consisted of several subthemes which described participants' experiences. Gender roles and a cultural legacy of being strong and hiding distress emerged as influential in participants' beliefs about managing personal difficulties. However, this was balanced with an acknowledgement that intergenerational differences highlighted an increasing acceptance amongst the community of talking about issues and seeking professional support. The findings offered support for the notion that understandings and responses to personal distress are subject to broad-ranging and interwoven influences. This complexity may be conceptualised as an 'exploratory map' where individuals make links between their current and newly encountered knowledge and experience to guide their personal route to coping and help-seeking. The study provides support for tailoring services to individual needs using a flexible approach which empowers individuals from black and minority ethnic groups by valuing explanatory models of distress alternative to the westernised medical model. Furthermore, findings emphasise the importance of readily available and accessible information about statutory and non-statutory community resources which use language relevant to the communities they are aimed at engaging.

How can we cope with the complexity of the environment? A "Learning by modelling" approach using qualitative reasoning for developing causal models and simulations with focus on Sustainable River Catchment Management  

NASA Astrophysics Data System (ADS)

The education system needs strategies to attract future scientists and practitioners. There is an alarming decline in the number of students choosing science subjects. Reasons for this include the perceived complexity and the lack of effective cognitive tools that enable learners to acquire the expertise in a way that fits its qualitative nature. The DynaLearn project utilises a "Learning by modelling" approach to deliver an individualised and engaging cognitive tool for acquiring conceptual knowledge. The modelling approach is based on qualitative reasoning, a research area within artificial intelligence, and allows for capturing and simulating qualitative systems knowledge. Educational activities within the DynaLearn software address topics at different levels of complexity, depending on the educational goals and settings. DynaLearn uses virtual characters in the learning environment as agents for engaging and motivating the students during their modelling exercise. The DynaLearn software represents an interactive learning environment in which learners are in control of their learning activities. The software is able to coach them individually based on their current progress, their knowledge needs and learning goals. Within the project 70 expert models on different environmental issues covering seven core topics (Earth Systems and Resources, The Living World, Human population, Land and Water Use, Energy Resources and Consumption, Pollution, and Global Changes) will be delivered. In the context of the core topic "Land and Water Use" the Institute of Hydrobiology and Aquatic Ecosystem Management has developed a model on Sustainable River Catchment Management. River systems with their catchments have been tremendously altered due to human pressures with serious consequences for the ecological integrity of riverine landscapes. The operation of hydropower plants, the implementation of flood protection measures, the regulation of flow and sediment regime and intensive land use in the catchments have created ecological problems. A sustainable, catchment-wide management of riverine landscapes is needed and stated by water right acts, e.g. the European Water Framework and Floods Directive. This interdisciplinary approach needs the integration of natural riverine processes, flood protection, resource management, landscape planning, and social and political aspects to achieve a sustainable development. Therefore the model shows the effects of different management strategies concerning flood protection, restoration measures and land use. The model illustrates the wide range of ecosystem services of riverine landscapes that contribute to human well-being such as water supply, hydropower generation, flood regulation, and recreational opportunities. The effects of different land use strategies in the catchment are highlighted by means of the Driver-Pressure-State-Impact-Response (DPSIR) framework. The model is used to support activities of students at the University as well as at High School within the DynaLearn Software to promote scientific culture in the secondary education system. Model fragments allow learners to re-use parts of the existing model at different levels of complexity. But learners can also construct their own conceptual system knowledge, either individually or in a collaborative setting, and using the model as a reference for comparisons of their own understanding. Of special interest for the DynaLearn project is the intended development of interdisciplinary and social skills like cooperative working, cross-linked thinking, problem solving, decision-making, and the identification of the conflicts between environment, economy, legislation, science, technology, and society. A comprehensive evaluation of the DynaLearn software is part of the project. To be effective, science education should focus on understanding scientific concepts and on application of scientific knowledge to everyday life. Conceptual knowledge of systems behaviour is crucial for society to understand and successfully interact w

"What is Found There"1: Qualitative Analysis of Physician-Nurse Collaboration Stories  

PubMed Central

Background Effective physician–nurse collaboration is an important, but incompletely understood determinant of patient and nurse satisfaction, and patient safety. Its impact on physicians has not been described. This study was undertaken to develop a fuller understanding of the collaboration experience and its outcomes. Methods Twenty-five medical residents, 32 staff nurses, 5 physician and 5 nurse faculty wrote narratives about successful collaboration; the narratives were then qualitatively analyzed. Narrative analysis was the initial qualitative method iteratively employed to identfy themes. A phenomenological approach was subsequently used to develop a framework for collaborative competence. Results Collaboration triggers, facilitative behaviors, outcomes and collaborative competence were the themes identified. Affect was identified in the triggers leading to collaboration and in its outcomes. Practioners typically entered a care episode feeling worrried, uncertain or inadequate and finished the interaction feeling satisfied, understood and grateful to their colleagues. The frequency of affective experience was not altered by gender, profession, or ethnicity. These experiences were particularly powerful for novice practioners of both disciplines and appear to have both formative and transformative potential. Collaborative competence was characterized by a series of graduated skills in clinical and relational domains. Many stories took place in the ICU and afterhours settings. Conclusions Despite the prevailing wisdom that nursing and medicine are qualitatively different, the stories from this study illuminate surprising commonalities in the collaboration experience, regardless of gender, age, experience, or profession. Collaborative competence can be defined and its component skills identified. Contexts of care can be identified that offer particularly rich opportunities to foster interprofessional collaboration.

The experience of being a partner to a spinal cord injured person: A phenomenological-hermeneutic study  

PubMed Central

This qualitative focuses on the personal experiences of partners to a spinal cord injured person. Using a Ricoeurian phenomenological-hermeneutic approach, we analysed seven partners’ narratives 1 and 2 years after their partner's injury. The study revealed how the injury was experienced from the partners’ perspective through the aftermath. In the acute phase after the injury, partners also felt harmed, and support was needed in relation to their own daily activities, eating, resting, and managing distress. During the institutionalized rehabilitation, partners felt torn between supporting the injured partner and the demanding tasks of everyday life outside the institution. After discharge, partners struggled for the injured partner to regain a well-functioning everyday life and for reestablishing life as a couple. The partner struggled to manage the overwhelming amount of everyday tasks. Some sought to reestablish their usual functions outside the family, whereas others focused on establishing a new life together. The partners experienced much distress and appreciated the support they got, but felt that they were mainly left to manage the difficult process on their own. PMID:22007262

Spin Hall phenomenology of magnetic dynamics  

NASA Astrophysics Data System (ADS)

We study the role of spin-orbit interactions in the coupled magnetoelectric dynamics of a ferromagnetic film coated with an electrical conductor. While the main thrust of this work is phenomenological, several popular simple models are considered microscopically in some detail, including Rashba and Dirac two-dimensional electron gases coupled to a magnetic insulator, as well as a diffusive spin Hall system. We focus on the long-wavelength magnetic dynamics that experiences current-induced torques and produces fictitious electromotive forces. Our phenomenology provides a suitable framework for analyzing experiments on current-induced magnetic dynamics and reciprocal charge pumping, including the effects of magnetoresistance and Gilbert-damping anisotropies, without a need to resort to any microscopic considerations or modeling. Finally, some remarks are made regarding the interplay of spin-orbit interactions and magnetic textures.

Phenomenological Modeling of Infrared Sources: Recent Advances  

NASA Technical Reports Server (NTRS)

Infrared observations from planned space facilities (e.g., ISO (Infrared Space Observatory), SIRTF (Space Infrared Telescope Facility)) will yield a large and uniform sample of high-quality data from both photometric and spectroscopic measurements. To maximize the scientific returns of these space missions, complementary theoretical studies must be undertaken to interpret these observations. A crucial step in such studies is the construction of phenomenological models in which we parameterize the observed radiation characteristics in terms of the physical source properties. In the last decade, models with increasing degree of physical realism (in terms of grain properties, physical processes, and source geometry) have been constructed for infrared sources. Here we review current capabilities available in the phenomenological modeling of infrared sources and discuss briefly directions for future research in this area.

Planetary Bootstrap: A Prelude to Biosphere Phenomenology  

NASA Astrophysics Data System (ADS)

This paper deals with systemic status as well as with some phenomenological and evolutionary aspects of biosphere. Biosphere is represented as multilevel autopoietic system in which different organizational levels are nested into each other. The conceptual model of punctuated epigenesis, biosphere evolutionary process is suggested, in which endogenous planetary organizational crises play role of evolutionary mechanism, creating novelty. The hypothesis is proposed, that the biosphere reaction on the humankind destructive activity reminds the distributed immune response of biological organism, described by F.Varela in his "cognitive immunology". The biosphere evolution is interpreted as the hermeneutical spiral of "Process Being" self-uncovering thus illustrating the historical process of transformation of biosphere as the type of Being in the periods of crises. Some arguments are adduced in favor of biosphere phenomenology development and application of the methods of second-order cybernetics to actual problems of planetary scale.

Phenomenology of SUSY with intermediate scale physics  

E-print Network

The presence of fields at an intermediate scale between the Electroweak and the Grand Unification scale modifies the evolution of the gauge couplings and consequently the running of other parameters of the Minimal Supersymmetric Standard Model, such as gauginos and scalar masses. The net effect is a modification of the low energy spectrum which affects both the collider phenomenology and the dark matter relic density.

The properties of cosmic rays with energies above 1PeV have to be deduced from the spacetime structure and particle content of the air showers which they initiate. In this review, a summary of the phenomenology of these giant air showers is presented. We describe the hadronic interaction models used to extrapolate results from collider data to ultra high energies, an also the main electromagnetic processes that govern the longitudinal shower evolution as well as the lateral spread of particles.

TASI Lectures on M Theory Phenomenology  

E-print Network

These lectures discuss some of the general issues in developing a phenomenology for Superstring Theory/M Theory. The focus is on the question: how might one obtain robust, generic predictions. For example, does the theory predict low energy supersymmetry breaking? In the course of these explorations, basics of supersymmetry and supersymmetry breaking, string moduli, cosmological issues, and other questions are addressed. The notion of approximate moduli and their possible role plays a central role in the discussion.

Skin Picking Phenomenology and Severity Comparison  

PubMed Central

Objective: Despite the substantial distress and impairment often associated with skin picking, there currently is only limited research examining various phenomenological aspects of this behavior. The present research contributes to the existing literature by investigating phenomenological variables related to skin picking, such as family involvement, anxiety, depression, and the emotional consequences of skin picking. Moreover, on the basis of symptom severity level, differences were explored between individuals with skin picking who were from a psychiatric population. Method: Forty individuals with various clinician-ascertained DSM-IV diagnoses in addition to skin picking symptomatology participated in the present study, which was conducted from September 2002 through January 2003. Participants were administered a self-report questionnaire (which assessed demographic, symptom, and past diagnostic information) as well as the Beck Depression Inventory, the Beck Anxiety Inventory, and the Self-Injury Interview. Results: Phenomenological data on various aspects of individuals with skin picking are presented. Individuals with mild skin picking and individuals with severe skin picking were compared and found to differ in the level of distress they experienced (t = ?2.35, p = .05) and the amount of damage caused by their picking behavior (t = ?3.06, p = .01). Conclusion: Overall, skin picking represents a behavior with its own unique characteristics and accompanying levels of distress and impairment that warrants specific attention by clinicians.

Undergraduate female science-related career choices: A phenomenological study  

NASA Astrophysics Data System (ADS)

This qualitative phenomenological study used a modified Groenewald's five steps method with semi-structured, recorded, and transcribed interviews to focus on the underrepresentation of females in science-related careers. The study explored the lived experiences of a purposive sample of 25 senior female college students attending a college in Macon, Georgia. Ten major themes emerged from the research study that included (a) journey to a science-related career; (b) realization of career interest; (c) family support (d) society's role; (e) professors' treatment of students; (f) lack of mentors and models; (g) gender and career success; (h) females and other disadvantages in science-related careers; (i) rewards of the journey; and (j) advice for the journey. The three minor themes identified were (a) decision-making; (b) career awareness; and (c) guidance. The key findings revealed that females pursuing a science degree or subsequent science-related career, shared their experience with other females interested in science as a career choice, dealt with barriers standing in the way of their personal goals, lack role models, and received little or no support from family and friends. The study findings may offer information to female college students interested in pursuing science-related careers and further foundational research on gender disparities in career choice.

Kinetic dielectric decrement revisited: phenomenology of finite ion concentrations  

E-print Network

With the help of a recently developed non-equilibrium approach, we investigate the ionic strength dependence of the Hubbard--Onsager dielectric decrement. We compute the depolarization of water molecules caused by the motion of ions in sodium chloride solutions from the dilute regime (0.035 M) up close to the saturation concentration (4.24 M), and find that the kinetic decrement displays a strong nonmonotonic behavior, in contrast to the prediction of available models. We introduce a phenomenological modification of the Hubbard--Onsager continuum theory, that takes into account the screening due to the ionic cloud at mean field level, and, is able to describe the kinetic decrement at high concentrations including the presence of a pronounced minimum.

Toward a critical ethical reflexivity: phenomenology and language in Maurice Merleau-Ponty.  


Working within the tradition of continental philosophy, this article argues in favour of a phenomenological understanding of language as a crucial component of bioethical inquiry. The authors challenge the 'commonsense' view of language, in which thinking appears as prior to speaking, and speech the straightforward vehicle of pre-existing thoughts. Drawing on Maurice Merleau-Ponty's (1908-1961) phenomenology of language, the authors claim that thinking takes place in and through the spoken word, in and through embodied language. This view resituates bioethics as a matter of bodies that speak. It also refigures the meaning of ethical self-reflexion, and in so doing offers an alternative view on reflexivity and critique. Referring to the Kantian critical tradition and its reception by Hannah Arendt and Michel Foucault, we advance a position we call 'critical ethical reflexivity'. We contend that Merleau-Ponty's phenomenology of language offers valuable insight into ethical reflexivity and subject formation. Moreover, his understanding of language may foster new qualitative empirical research in bioethics, lead to more nuanced methods for interpreting personal narratives, and promote critical self-reflexion as necessary for bioethical inquiry.

The genesis of empathy in human development: a phenomenological reconstruction.  


In phenomenology, theories of empathy are intimately connected with the question of how it is possible to have insight into the mind of the other person. In this article, the author wants to show why it is self-evident for us that the other person is having experiences. In order to do so, it is not enough to discuss the phenomenon of empathy with a starting point in the already constituted adult person; instead the article presents a genetic approach to human development. The author thus contrasts Edith Stein's discussion of Einfühlung (empathy), which takes its starting point in the experience of the grown-up, with Max Scheler's discussion of Einsfühlung (feeling of oneness), where the relation between mother and infant is taken as one example. Maurice Merleau-Ponty's discussion of the world of the infant is read as one way of developing Scheler's theory of intersubjectivity and of Einsfühlung. This genetic approach is developed further into a phenomenological analysis of the experience of the fetus and of birth. The author argues that the analysis of the fetus highlights the distinction between knowing that another person is having experiences, and knowing the specific content of the other person's experiences. The fetus does not experience different persons, but has a pre-subjective experience of life that includes what is later experienced as belonging to "another." Later in life, the experience of empathy, as an experience of a specific content, can be developed from this experience. In this way empathy and Einsfühlung can be understood as complementary rather than as competing phenomena. PMID:24043575

Challenges and promises of integrating knowledge engineering and qualitative methods  

NASA Astrophysics Data System (ADS)

Our goal is to expose some of the close ties that exist between knowledge engineering (KE) and qualitative methodology (QM). Many key concepts of qualitative research, for example meaning, commonsense, understanding, and everyday life, overlap with central research concerns in artificial intelligence. These shared interests constitute a largely unexplored avenue for interdisciplinary cooperation. We compare and take some steps toward integrating two historically diverse methodologies by exploring the commonalities of KE and QM both from a substantive and a methodological/technical perspective. In the second part of this essay, we address knowledge acquisition problems and procedures. Knowledge acquisition within KE has been based primarily on cognitive psychology/science foundations, whereas knowledge acquisition within QM has a broader foundation in phenomenology, symbolic interactionism, and ethnomethodology. Our discussion and examples are interdisciplinary in nature. We do not suggest that there is a clash between the KE and QM frameworks, but rather that the lack of communication potentially may limit each framework's future development.

Phenomenological approach to the statistics and dynamics of model systems  

SciTech Connect

This thesis investigates the equilibrium and nonequilibrium properties of some model systems, and consists of two parts. Part 1 deals with phase transitions in frustrated xy models, which can serve as a model for the coupled Josephson junction arrays. The Hubbard-Stratanovich transform is developed to construct the Landau-Ginzburg-Wilson Hamiltonians for uniformly frustrated xy models both on a square lattice and on a triangular lattice, which reflect the formation of various superlattices according to the frustration f. Near the critical point, the system with f equal to 1/4 on a triangular lattice is shown to belong to the same universality class as the fully frustrated system on a square lattice. By decomposing two mode systems into two coupled xy models and by applying the Migdal-Kadanoff approximation, the possibilities of Ising-like or three-state Potts-like transition are shown in addition to the Kosterlitz-Thouless-like ones. Part 2 considers the time evaluation of model systems with retarded interactions. For such systems, a master equation is derived with non-Markovian character. It is shown that in higher dimensions, the interplay between interaction strength and delay can lead to complicated behavior.

Quantum Geometry Phenomenology: Angle and Semiclassical States  

E-print Network

The phenomenology for the deep spatial geometry of loop quantum gravity is discussed. In the context of a simple model of an atom of space, it is shown how purely combinatorial structures can affect observations. The angle operator is used to develop a model of angular corrections to local, continuum flat-space 3-geometries. The physical effects involve neither breaking of local Lorentz invariance nor Planck scale suppression, but rather reply on only the combinatorics of SU(2) recouping theory. Bhabha scattering is discussed as an example of how the effects might be observationally accessible.

A rigorous extraction of the deuteron charge form factors from tensor polarization data in elastic electron-deuteron scattering, at given values of the 4-momentum transfer, is presented. Then the world data for elastic electron-deuteron scattering is used to parameterize, in three different ways, the three electromagnetic form factors of the deuteron in the 4-momentum transfer range 0-7 fm^-1. This procedure is made possible with the advent of recent polarization measurements. The parameterizations allow a phenomenological characterization of the deuteron electromagnetic structure. They can be used to remove ambiguities in the form factors extraction from future polarization data.

Phenomenology and treatment of behavioural addictions.  


Behavioural addictions are characterized by an inability to resist an urge or drive resulting in actions that are harmful to oneself or others. Behavioural addictions share characteristics with substance and alcohol abuse, and in areas such as natural history, phenomenology, and adverse consequences. Behavioural addictions include pathological gambling, kleptomania, pyromania, compulsive buying, compulsive sexual behaviour, Internet addiction, and binge eating disorder. Few studies have examined the efficacy of pharmacological and psychological treatment for the various behavioural addictions, and therefore, currently, no treatment recommendations can be made.

Phenomenology of Dirac neutrinogenesis in split supersymmetry  

NASA Astrophysics Data System (ADS)

In split-supersymmetry scenarios the possibility of having a very heavy gravitino opens the door to alleviate or completely solve the worrisome “gravitino problem” in the context of supersymmetric baryogenesis models. Here we assume that the gravitino may indeed be heavy and that Majorana masses for neutrinos are forbidden as well as direct Higgs Yukawa couplings between left- and right-handed neutrinos. We investigate the viability of the mechansim known as Dirac leptogenesis (or neutrinogenesis), both in solving the baryogenesis puzzle and explaining the observed neutrino sector phenomenology. To successfully address these issues, the scenario requires the introduction of at least two new heavy fields. If a hierarchy among these new fields is introduced, and some reasonable stipulations are made on the couplings that appear in the superpotential, it becomes a generic feature to obtain the observed large lepton mixing angles. We show that in this case, it is possible simultaneously to obtain both the correct neutrino phenomenology and enough baryon number, making thermal Dirac neutrinogenesis viable. However, due to cosmological constraints, its ability to satisfy these constraints depends nontrivially on model parameters of the overall theory, particularly the gravitino mass. Split supersymmetry with 105GeV?m3/2?1010GeV emerges as a “natural habitat” for thermal Dirac neutrinogenesis.

Analogue model for quantum gravity phenomenology  

E-print Network

So called "analogue models" use condensed matter systems (typically hydrodynamic) to set up an "effective metric" and to model curved-space quantum field theory in a physical system where all the microscopic degrees of freedom are well understood. Known analogue models typically lead to massless minimally coupled scalar fields. We present an extended "analogue space-time" programme by investigating a condensed-matter system - in and beyond the hydrodynamic limit - that is in principle capable of simulating the massive Klein-Gordon equation in curved spacetime. Since many elementary particles have mass, this is an essential step in building realistic analogue models, and an essential first step towards simulating quantum gravity phenomenology. Specifically, we consider the class of two-component BECs subject to laser-induced transitions between the components, and we show that this model is an example for Lorentz invariance violation due to ultraviolet physics. Furthermore our model suggests constraints on quantum gravity phenomenology in terms of the "naturalness problem" and "universality issue".

BACKGROUND Physical examination teaching using actual patients is an important part of medical training. The patient experience undergoing this type of teaching is not well-understood. OBJECTIVE To understand the meaning of physical examination teaching for patients. DESIGN Phenomenological qualitative study using semi-structured interviews. PARTICIPANTS Patients who underwent a physical examination-based teaching session at an urban Veterans Affairs Medical Center. APPROACH A purposive sampling strategy was used to include a diversity of patient teaching experiences. Multiple interviewers triangulated data collection. Interviews continued until new themes were no longer heard (total of 12 interviews). Interviews were recorded and transcribed verbatim. Coding was performed by two investigators and peer-checked. Themes were identified and meanings extracted from themes. KEY RESULTS Seven themes emerged from the data: positive impression of students; participation considered part of the program; expect students to do their job: hands-on learning; interaction with students is positive; some aspects of encounter unexpected; range of benefits to participation; improve convenience and interaction. Physical examination teaching had four possible meanings for patients: Tolerance, Helping, Social, and Learning. We found it possible for a patient to move from one meaning to another, based on the teaching session experience. CONCLUSIONS Physical examination teaching can benefit patients. Patients have the potential to gain more value from the experience based on the group interaction. PMID:20352363

ABSTRACT Purpose: Military physiotherapists in the Canadian Forces meet the unique rehabilitation needs of military personnel. Recently, the physiotherapy officer role has evolved in response to the Canadian Forces' involvement in the combat theatre of operations of Afghanistan, and this has created new and unique challenges and demands. The purpose of this study was to describe the experiences and challenges of military physiotherapists deployed to Afghanistan. Methods: A qualitative research design guided by descriptive phenomenology involved recruitment of key informants and in-depth interviews as the data collection method. The interviews were transcribed verbatim and the data analyzed using a foundational thematic analysis approach. Strategies of peer review and member checking were incorporated into the study design. Results: Six military physiotherapists were interviewed. They described rewarding experiences that were stressful yet highly career-satisfying. Main challenges revolved around heavy workloads, an expanded scope of practice as sole-charge practitioners, and the consequences and criticality of their clinical decisions. Conclusions: Our findings suggest that enhanced pre-deployment training and the implementation of a stronger support network will improve the capabilities of military physiotherapists deployed to difficult theatres of operations. This type of systematic and comprehensive research is needed to assist the Canadian Forces in proactively preparing and supporting physiotherapists deployed on future missions. PMID:22942524

Qualitative visual environment retrieval.  


A system for retrieval of an unstructured environment under static and dynamic scenarios is proposed. The use of cylindrical mosaics or omnidirectional images is exploited for providing a rich description about the surrounding environment spanning 360 degrees. The environment description is based on defining the attributes of the nodes of a graph derived from the angular partitions of the captured images. Content-based image retrieval for each of these partitions is performed on an exemplar image database to annotate the nodes of the graph. The complete environment description is recovered by collating the retrieval results over all the partitions based on a simple voting scheme. This offers a qualitative description of the location in a totally natural and unstructured surrounding. The experiments yield quite promising results. PMID:17186813

The Phenomenology and Neurobiology of Delusion Formation During Psychosis Onset: Jaspers, Truman Symptoms, and Aberrant Salience  

PubMed Central

Following the publication of Karl Jaspers’ General Psychopathology (1913), delusions have been characterized as being nonunderstandable in terms of the person’s biography, motivations, and historical-cultural context. According to Jaspers, this loss of understandability is due to an underlying neurobiological process, which has interrupted the normal development of the individual’s personality. Inheriting the 19th-century division between the natural- and human-historical sciences, Jaspers emphasizes the psychological understanding of mental disorders as narrative-based, holistic, and contextual. By doing so, he embraces cultural, ethnic, and individual differences and anticipates a person-centered medicine. However, he also affirms the value of explanatory neurobiological approaches, especially in the research and diagnosis of delusions. The phenomenological approach leads to neurobiological hypotheses, which can be tested experimentally. The present article addresses these issues by illustrating Jaspers’ fundamental contribution to current neurobiological research concerning the formation of delusions during early phases of psychosis. Specifically, we present delusional mood and Truman symptoms as core phenomenological features at the origin of psychosis onset, and we discuss their neurobiological substrate with the aberrant salience and dopamine dysregulation models. Jaspers and his successors’ phenomenological approach suggests that delusion is formed through loss of context in its experiential-perceptual origins. This is consistent with the more recent neurobiological models. PMID:23354468

Structured Qualitative Research: Organizing "Mountains of Words" for Data Analysis, both Qualitative and Quantitative  

PubMed Central

Qualitative research creates mountains of words. U.S. federal funding supports mostly structured qualitative research, which is designed to test hypotheses using semi-quantitative coding and analysis. The authors have 30 years of experience in designing and completing major qualitative research projects, mainly funded by the US National Institute on Drug Abuse [NIDA]. This article reports on strategies for planning, organizing, collecting, managing, storing, retrieving, analyzing, and writing about qualitative data so as to most efficiently manage the mountains of words collected in large-scale ethnographic projects. Multiple benefits accrue from this approach. Several different staff members can contribute to the data collection, even when working from remote locations. Field expenditures are linked to units of work so productivity is measured, many staff in various locations have access to use and analyze the data, quantitative data can be derived from data that is primarily qualitative, and improved efficiencies of resources are developed. The major difficulties involve a need for staff who can program and manage large databases, and who can be skillful analysts of both qualitative and quantitative data. PMID:20222777

Phenomenological Model of Current Sheet Canting in Pulsed Electromagnetic Accelerators  

NASA Technical Reports Server (NTRS)

The phenomenon of current sheet canting in pulsed electromagnetic accelerators is the departure of the plasma sheet (that carries the current) from a plane that is perpendicular to the electrodes to one that is skewed, or tipped. Review of pulsed electromagnetic accelerator literature reveals that current sheet canting is a ubiquitous phenomenon - occurring in all of the standard accelerator geometries. Developing an understanding of current sheet canting is important because it can detract from the propellant sweeping capabilities of current sheets and, hence, negatively impact the overall efficiency of pulsed electromagnetic accelerators. In the present study, it is postulated that depletion of plasma near the anode, which results from axial density gradient induced diamagnetic drift, occurs during the early stages of the discharge, creating a density gradient normal to the anode, with a characteristic length on the order of the ion skin depth. Rapid penetration of the magnetic field through this region ensues, due to the Hall effect, leading to a canted current front ahead of the initial current conduction channel. In this model, once the current sheet reaches appreciable speeds, entrainment of stationary propellant replenishes plasma in the anode region, inhibiting further Hall-convective transport of the magnetic field; however, the previously established tilted current sheet remains at a fairly constant canting angle for the remainder of the discharge cycle, exerting a transverse J x B force which drives plasma toward the cathode and accumulates it there. This proposed sequence of events has been incorporated into a phenomenological model. The model predicts that canting can be reduced by using low atomic mass propellants with high propellant loading number density; the model results are shown to give qualitative agreement with experimentally measured canting angle mass dependence trends.

The Phenomenology of Gravitino Dark Matter Scenarios in Supergravity Models  

E-print Network

We review the phenomenology of gravitino dark matter within supergravity framework. Gravitino can be dark matter if it is the lightest supersymmetric particle, which is stable if R-parity is conserved. There are several distinct scenarios depending on what the next to lightest supersymmetric particle (NLSP) is. We discuss the constraints and summarize the phenomenology of neutralino, stau, stop and sneutrino NLSPs.

Evaluation of Mesoscale Model Phenomenological Verification Techniques  

NASA Technical Reports Server (NTRS)

Forecasters at the Spaceflight Meteorology Group, 45th Weather Squadron, and National Weather Service in Melbourne, FL use mesoscale numerical weather prediction model output in creating their operational forecasts. These models aid in forecasting weather phenomena that could compromise the safety of launch, landing, and daily ground operations and must produce reasonable weather forecasts in order for their output to be useful in operations. Considering the importance of model forecasts to operations, their accuracy in forecasting critical weather phenomena must be verified to determine their usefulness. The currently-used traditional verification techniques involve an objective point-by-point comparison of model output and observations valid at the same time and location. The resulting statistics can unfairly penalize high-resolution models that make realistic forecasts of a certain phenomena, but are offset from the observations in small time and/or space increments. Manual subjective verification can provide a more valid representation of model performance, but is time-consuming and prone to personal biases. An objective technique that verifies specific meteorological phenomena, much in the way a human would in a subjective evaluation, would likely produce a more realistic assessment of model performance. Such techniques are being developed in the research community. The Applied Meteorology Unit (AMU) was tasked to conduct a literature search to identify phenomenological verification techniques being developed, determine if any are ready to use operationally, and outline the steps needed to implement any operationally-ready techniques into the Advanced Weather Information Processing System (AWIPS). The AMU conducted a search of all literature on the topic of phenomenological-based mesoscale model verification techniques and found 10 different techniques in various stages of development. Six of the techniques were developed to verify precipitation forecasts, one to verify sea breeze forecasts, and three were capable of verifying several phenomena. The AMU also determined the feasibility of transitioning each technique into operations and rated the operational capability of each technique on a subjective 1-10 scale: (1) 1 indicates that the technique is only in the initial stages of development, (2) 2-5 indicates that the technique is still undergoing modifications and is not ready for operations, (3) 6-8 indicates a higher probability of integrating the technique into AWIPS with code modifications, and (4) 9-10 indicates that the technique was created for AWIPS and is ready for implementation. Eight of the techniques were assigned a rating of 5 or below. The other two received ratings of 6 and 7, and none of the techniques a rating of 9-10. At the current time, there are no phenomenological model verification techniques ready for operational use. However, several of the techniques described in this report may become viable techniques in the future and should be monitored for updates in the literature. The desire to use a phenomenological verification technique is widespread in the modeling community, and it is likely that other techniques besides those described herein are being developed, but the work has not yet been published. Therefore, the AMIU recommends that the literature continue to be monitored for updates to the techniques described in this report and for new techniques being developed whose results have not yet been published. 111

Mid-wave infrared DIAL noise phenomenology  

SciTech Connect

LLNL has utilized optical parametric oscillator technology to develop and field a rapidly-tunable mid-wave infrared (MWIR) DIAL system. The system can be tuned at up to 1 KHz over the 3.3-3.8 micron spectral region, where hydrogen-bond stretching modes provide spectroscopic signatures for a wide variety of chemicals. We have fielded the DIAL system on the LLNL site with targets at horizontal ranges of up to 2 km. We have collected data on noise levels and correlations and their dependences on range, turbulence, and receiver aperture size. In this paper we describe some of the implications of this data for MWIR DIAL phenomenology. In particular, the interplay of turbulence and speckle to produce the observed noise fluctuations at short ranges (<500 m) is presented.

Phenomenology of Gamma-Ray Jets  

NASA Astrophysics Data System (ADS)

We discuss some phenomenological aspects of ?-ray emitting jets. In particular, we present calculations of the ?-sphere and ?-sphere for various target photon fields and employ them to demonstrate how ?-ray observations at very high energies can be used to constraint the Doppler factor of the emitting plasma and the production of VHE neutrinos. We also consider some implications of the rapid TeV variability observed in M87 and the TeV blazars, and propose a model for the very rapid TeV flares observed with HESS and MAGIC in some blazars, that accommodates the relatively small Doppler factors inferred from radio observations. Finally, we briefly discuss the prospects for detecting VHE neutrinos from relativistic jets.

Hitchin's Equations and M-Theory Phenomenology  

E-print Network

Phenomenological compactifications of M-theory involve 7-manifolds with G_2 holonomy and various singularities. Here we study local geometries with such singularities, by thinking of them as compactifications of 7d supersymmetric Yang-Mills theory on a three-manifold Q_3. We give a general discussion of compactifications of 7d Yang-Mills theory in terms of Higgs bundles on Q_3. We show they can be constructed using spectral covers, which are Lagrangian branes with a flat connection in the cotangent bundle T^*Q_3. We explain the dictionary with ALE fibrations over Q_3 and conjecture that these configurations have G_2 holonomy. We further develop tools to study the low energy effective theory of such a model. We show that the naive massless spectrum is corrected by instanton effects. Taking the instanton effects into account, we find that the massless spectrum and many of the interactions can be computed with Morse theoretic methods.

Phenomenology of Strongly Coupled Heterotic String Theory  

E-print Network

This is the text of a talk given at the Inaugural Conference of the Asia Pacific Center for Theoretical Physics, Seoul, Korea, June 9, 1996. If nature is described by string theory, and if the compactification radius is large (as suggested by the unification of couplings), then the theory is in a regime best described by the low energy limit of $M$-theory. We discuss some phenomenological aspects of this view. The scale at which conventional quantum field theory breaks down is of order the unification scale and consequently (approximate) discrete symmetries are essential to prevent proton decay. There are one or more light axions, one of which solves the strong CP problem. Modular cosmology is still problematic but much more complex than in perturbative string vacua.

[Phenomenology of multiculturalism and intercultural pluralism].  


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.

Warped Phenomenology of Higher-Derivative Gravity  

SciTech Connect

We examine the phenomenological implications at colliders for the existence of higher-derivative gravity terms as extensions to the Randall-Sundrum model. Such terms are expected to arise on rather general grounds, e.g., from string theory. In 5-d, if we demand that the theory be unitary and ghost free, these new contributions to the bulk action are uniquely of the Gauss-Bonnet form. We demonstrate that the usual expectations for the production cross section and detailed properties of graviton Kaluza-Klein resonances and TeV-scale black holes can be substantially altered by existence of these additional contributions. It is shown that measurements at future colliders will be highly sensitive to the presence of such terms.

Agnew's general strain theory reconsidered: a phenomenological perspective.  


Since its inception, strain theory has attempted to explore the dynamic evoked between the process of goal identification and the process of goal acquisition as this relates to subsequent criminal behavior. Over the years of its development, strain theorists have attempted to broaden the initial scope of this perspective. Robert Agnew with his general strain theory has sought to introduce a variety of other factors relative to the experience of strain and the capacity they represent concerning subsequent criminal activity. However, these recent developments have not addressed until recently, and only in somewhat limited ways, the theoretical and methodologic implications and limits of this theoretical approach. This article proposes that the way in which Agnew's formulation of general strain, particularly in its most recent conceptualization as story lines, fundamentally transforms the theoretical and methodological grounding of this approach but fails to offer a clearly articulated alternative theoretical perspective by which to conceptualize this "turn." Phenomenology provides such an alternative perspective and helps to greatly expand our understanding of the human experience of strain. PMID:20807864

Qualitative interviewing as measurement.  


The attribution of beliefs and other propositional attitudes is best understood as a form of measurement, however counter-intuitive this may seem. Measurement theory does not require that the thing measured should be a magnitude, or that the calibration of the measuring instrument should be numerical. It only requires a homomorphism between the represented domain and the representing domain. On this basis, maps measure parts of the world, usually geographical locations, and 'belief' statements measure other parts of the world, namely people's aptitudes. Having outlined an argument for this view, I deal with an obvious objection to it: that self-attribution of belief cannot be an exercise in measurement, because we are all aware, from introspection, that our beliefs have an intrinsically semantic form. Subsequently, I turn to the philosophical and methodological ramifications of the measurement theoretic view. I argue, first, that it undermines at least one version of constructivism and, second, that it provides an effective alternative to the residually Cartesian philosophy that underpins much qualitative research. Like other anti-Cartesian strategies, belief-attribution-as-measurement implies that the objective world is far more knowable than the subjective one, and that reality is ontologically prior to meaning. I regard this result as both plausible and welcome. PMID:20415963

What are the neurocognitive correlates of basic self-disturbance in schizophrenia? Integrating phenomenology and neurocognition: Part 2 (aberrant salience).  


Phenomenological research indicates that disturbance of the basic sense of self may be a core phenotypic marker of schizophrenia spectrum disorders. Basic self-disturbance refers to disruption of the sense of ownership of experience and agency of action and is associated with a variety of anomalous subjective experiences. Little is known about the neurocognitive underpinnings of basic self-disturbance. In these two theoretical papers (of which this is Part 2), we review some recent phenomenological and neurocognitive research and point to a convergence of these approaches around the concept of self-disturbance. Specifically, we propose that subjective anomalies associated with basic self-disturbance may be associated with: 1. source monitoring deficits, which may contribute particularly to disturbances of "ownership" and "mineness" (the phenomenological notion of presence or self-affection) and 2. aberrant salience, and associated disturbances of memory, prediction and attention processes, which may contribute to hyper-reflexivity, disturbed "grip" or "hold" on perceptual and conceptual fields, and disturbances of intuitive social understanding ("common sense"). In this paper (Part 2) we focus on aberrant salience. Part 1 (this issue) addressed source monitoring deficits. Empirical studies are required in a variety of populations in order to test these proposed associations between phenomenological and neurocognitive aspects of self-disturbance in schizophrenia. An integration of findings across the phenomenological and neurocognitive "levels" would represent a significant advance in the understanding of schizophrenia and possibly enhance early identification and intervention strategies.

Kaonic atoms and in-medium K-N amplitudes II: interplay between theory and phenomenology  

E-print Network

A microscopic kaonic-atom optical potential $V^{(1)}_{K^-}$ is constructed, using the Ikeda-Hyodo-Weise NLO chiral $K^-N$ subthreshold scattering amplitudes constrained by the kaonic hydrogen SIDDHARTA measurement, and incorporating Pauli correlations within the Waas-Rho-Weise generalization of the Ericson-Ericson multiple-scattering approach. Good fits to kaonic atom data over the entire periodic table require additionally sizable $K^-NN$--motivated absorptive and dispersive phenomenological terms, in agreement with our former analysis based on a post-SIDDHARTA in-medium chirally-inspired NLO separable model by Ciepl\\'{y} and Smejkal. Such terms are included by introducing a phenomenological potential $V^{(2)}_{K^-}$ and coupling it self consistently to $V^{(1)}_{K^-}$. Properties of resulting kaonic atom potentials are discussed with special attention paid to the role of $K^-$-nuclear absorption and to the extraction of density-dependent amplitudes representing $K^-$ multi-nucleon processes.

Simultaneous Measurement of Tracer and Interdiffusion Coefficients: An Isotopic Phenomenological Diffusion Formalism for the Binary Alloy  

SciTech Connect

In this paper, a new development of the classic Onsager phenomenological formalism is derived using relations based on linear response theory. The development concerns the correct description of the fluxes of the atomic isotopes. The resulting expressions in the laboratory frame are surprisingly simple and consist of terms coming from the standard interdiffusion expressions and from Fick s first law where the tracer diffusion coefficient is involved thus providing a better understanding of the relationship between the two approaches - Fick s first law and the Onsager phenomenological formalism. From an experimental application perspective, the new development is applied to the binary alloy case. The formalism provides the means to obtain the interdiffusion coefficient and tracer diffusion coefficients simultaneously from analysis of the interdiffusion concentration profiles in a single experiment.

Noncommutative Geometry Spectral Action as a Framework for Unification:. Introduction and Phenomenological/cosmological Consequences  

NASA Astrophysics Data System (ADS)

I will summarize Noncommutative Geometry Spectral Action, an elegant geometrical model valid at unification scale, which offers a purely gravitational explanation of the Standard Model, the most successful phenomenological model of particle physics. Noncommutative geometry states that close to the Planck energy scale, spacetime has a fine structure and proposes that it is given as the product of a four-dimensional continuum compact Riemaniann manifold by a tiny discrete finite noncommutative space. The spectral action principle, a universal action functional on spectral triples which depends only on the spectrum of the Dirac operator, applied to this almost commutative product geometry, leads to the full Standard Model, including neutrino mixing which has Majorana mass terms and a see-saw mechanism, minimally coupled to gravity. It also makes various predictions at unification scale. I will review some of the phenomenological and cosmological consequences of this beautiful and purely geometrical approach to unification.

A Qualitative Assessment of Program Characteristics for Preventing Secondary Conditions in Individuals with Fetal Alcohol Spectrum Disorders  

PubMed Central

Background Fetal alcohol spectrum disorders (FASD) are a major public health problem that affects 2 to 5 percent of the population. Individuals with FASD are at high risk for secondary conditions, such as mental health problems, school disruptions, and trouble with the law. Evidence-based intervention programs are needed to prevent and treat secondary conditions in this population. Objectives The purpose of this study was to identify intervention program characteristics for preventing secondary conditions in individuals with FASD from the perspectives of parents and service providers. Methods This qualitative study utilized a phenomenological approach to identify program characteristics for preventing secondary conditions. Twenty-five parents of children (ages 3 to 33) with FASD and 18 service providers participated in focus groups or individual interviews. Data was systematically analyzed using a framework approach. Themes did not differ by participant type. Results Participants emphasized five primary characteristics of intervention programs for individuals with FASD. Programs need to 1) be available to individuals across the lifespan, 2) have a prevention focus, 3) be individualized, 4) be comprehensive, and 5) be coordinated across systems and developmental stages. Participants discussed a variety of specific intervention strategies for each developmental stage and setting. Conclusions Program characteristics identified in this study are consistent with a positive behavior support framework. This framework is discussed in the context of research on existing interventions for individuals with FASD, and recommendations for future intervention development and evaluation are highlighted.

Emergent phenomenology from deterministic Cartan-Randers systems  

E-print Network

We consider specific deterministic quantum models of Cartan-Randers type and show how a dualized abelian gauge symmetry, diffeomorphism invariance, the Principle of Inertia, reversibility of phenomenological dynamics, maximal acceleration and maximal propagation speed for matter arise from such models in an phenomenological description. Two particular predictions are highlighted: the first is the value of maximal acceleration is universal and has the value of order 10^{52} m/s^2. The second prediction is that gauge symmetries in phenomenological models must come dualized and containing an abelian sector.

Data collection is no longer limited to paper-and-pencil format, and numerous methods are now available through Internet and electronic resources. With these techniques, researchers are not burdened with entering data manually and data analysis is facilitated by software programs. Quantitative research is supported by the use of computer software and provides ease in the management of large data sets and rapid analysis of numeric statistical methods. New technologies are emerging to support qualitative research with the availability of computer-assisted qualitative data analysis software (CAQDAS).CAQDAS will be presented with a discussion of advantages, limitations, controversial issues, and recommendations for this type of software use.

Qualitative Reasoning for Additional Die Casting Applications  

SciTech Connect

If manufacturing incompatibility of a product can be evaluated at the early product design stage, the designers can modify their design to reduce the effect of potential manufacturing problems. This will result in fewer manufacturing problems, less redsign, less expensive tooling, lower cost, better quality, and shorter development time. For a given design, geometric reasoning can predict qualitatively the behaviors of a physical manufacturing process by representing and reasoning with incomplete knowledge of the physical phenomena. It integrates a design with manufacturing processes to help designers simultaneously consider design goals and manufacturing constraints during the early design stage. The geometric reasoning approach can encourage design engineers to qualitatively evaluate the compatibility of their design with manufacturing limitations and requirements.

Violations of Einstein's Relativity: Motivations, Theory, and Phenomenology  

E-print Network

One of the most difficult questions in present-day physics concerns a fundamental theory of space, time, and matter that incorporates a consistent quantum description of gravity. There are various theoretical approaches to such a quantum-gravity theory. Nevertheless, experimental progress is hampered in this research field because many models predict deviations from established physics that are suppressed by some power of the Planck scale, which currently appears to be immeasurably small. However, tests of relativity theory provide one promising avenue to overcome this phenomenological obstacle: many models for underlying physics can accommodate a small breakdown of Lorentz symmetry, and numerous feasible Lorentz-symmetry tests have Planck reach. Such mild violations of Einstein's relativity have therefore become a focus of recent research efforts. This presentation provides a brief survey of the key ideas in this research field and is geared at both experimentalists and theorists. In particular, several theoretical mechanisms leading to deviations from relativity theory are presented; the standard theoretical framework for relativity violations at currently accessible energy scales (i.e., the SME) is reviewed, and various present and near-future experimental efforts within this field are discussed.

Rediscovering Psychopathology: The Epistemology and Phenomenology of the Psychiatric Object  

PubMed Central

Questions concerning both the ontology and epistemology of the “psychiatric object” (symptoms and signs) should be at the forefront of current concerns of psychiatry as a clinical neuroscience. We argue that neglect of these issues is a crucial source of the stagnation of psychiatric research. In honor of the centenary of Karl Jaspers’ book, General Psychopathology, we offer a critique of the contemporary “operationalist” epistemology, a critique that is consistent with Jaspers’ views. Symptoms and signs cannot be properly understood or identified apart from an appreciation of the nature of consciousness or subjectivity, which in turn cannot be treated as a collection of thing-like, mutually independent objects, accessible to context-free, “atheoretical” definitions or unproblematic forms of measurement (as is often assumed in structured interviewing). Adequate and faithful distinctions in the phenomenal or experiential realm are therefore a fundamental prerequisite for classification, treatment, and research. This requires a multidisciplinary approach, incorporating (among other things) insights provided by psychology, phenomenological philosophy, and the philosophy of mind. PMID:23267191

Phenomenology of a light scalar: The dilaton  

SciTech Connect

We make use of the language of nonlinear realizations to analyze electroweak symmetry breaking scenarios in which a light dilaton emerges from the breaking of a nearly conformal strong dynamics and compare the phenomenology of the dilaton to that of the well-motivated light composite Higgs scenario. We argue that - in addition to departures in the decay/production rates into massless gauge bosons mediated by the conformal anomaly - characterizing features of the light dilaton scenario are enhancements in off-shell events at high invariant mass involving two longitudinally polarized vector bosons and a dilaton, and tree-level flavor violating processes. Accommodating both electroweak precision measurements and flavor constraints appears especially challenging in the ambiguous scenario in which the Higgs and the dilaton fields strongly mix. We show that warped higgsless models of electroweak symmetry breaking are explicit and tractable realizations of this limiting case. The relation between the naive radion profile often adopted in the study of holographic realizations of the light dilaton scenario and the actual dynamical dilaton field is clarified in the Appendix.

Introduction to Quantum-Gravity Phenomenology  

E-print Network

After a brief review of the first phase of development of Quantum-Gravity Phenomenology, I argue that this research line is now ready to enter a more advanced phase: while at first it was legitimate to resort to heuristic order-of-magnitude estimates, which were sufficient to establish that sensitivity to Planck-scale effects can be achieved, we should now rely on detailed analyses of some reference test theories. I illustrate this point in the specific example of studies of Planck-scale modifications of the energy/momentum dispersion relation, for which I consider two test theories. Both the photon-stability analyses and the Crab-nebula synchrotron-radiation analyses, which had raised high hopes of ``beyond-Plankian'' experimental bounds, turn out to be rather ineffective in constraining the two test theories. Examples of analyses which can provide constraints of rather wide applicability are the so-called ``time-of-flight analyses'', in the context of observations of gamma-ray bursts, and the analyses of the cosmic-ray spectrum near the GZK scale.

Quantum corrected spherical collapse: A phenomenological framework  

SciTech Connect

A phenomenological framework is presented for incorporating quantum gravity motivated corrections into the dynamics of spherically symmetric collapse. The effective equations are derived from a variational principle that guarantees energy conservation and the existence of a Birkhoff theorem. The gravitational potential can be chosen as a function of the areal radius to yield specific nonsingular static spherically symmetric solutions that generically have two horizons. For a specific choice of potential, the effective stress energy tensor violates only the dominant energy condition. The violations are maximum near the inner horizon and die off rapidly. A numerical study of the quantum corrected collapse of a spherically symmetric scalar field in this case reveals that the modified gravitational potential prevents the formation of a central singularity and ultimately yields a static, mostly vacuum, spacetime with two horizons. The matter 'piles up' on the inner horizon giving rise to mass inflation at late times. The Cauchy horizon is transformed into a null, weak singularity, but in contrast to Einstein gravity, the absence of a central singularity renders this null singularity stable.

New Dimensions for Randall-Sundrum Phenomenology  

SciTech Connect

We consider a 6D extension of the Randall-Sundrum (RS) model, RS6, where the Standard Model (SM) gauge fields are allowed to propagate in an additional dimension, compactified on S{sup 1} or S{sup 1}/Z{sub 2}. In a minimal scenario, fermions propagate in the 5D RS subspace and their localization provides a model of flavor. New Kaluza-Klein (KK) states, corresponding to excitations of the gauge fields along the 6th dimension, appear near the TeV scale. The new gauge KK modes behave differently from those in the 5D warped models. These RS6 states have couplings with strong dependence on 5D field localization and, within the SM, only interact with heavy fermions and the Higgs sector, to a very good approximation. Thus, the collider phenomenology of the new gauge KK states sensitively depends on the 5D fermion geography. We briefly discuss inclusion of SM fermions in all 6 dimensions, as well as the possibility of going beyond 6D.

Five-dimensional geometries with a linearly varying dilaton background arise as gravity duals of TeV Little String Theories (LSTs) and provide a solution of the hierarchy problem through extra dimensions. The unique Kaluza-Klein graviton spectrum has a mass gap on the order of the dilaton slope followed by a closely spaced discretum of states. We study in detail the graviton phenomenology in this scenario, allowing the dilaton slope to vary from the MeV to the TeV scale. When the dilaton slope is large enough so that individual KK resonances can be resolved at the LHC, several of them can be discovered simultaneously and allow for the linear dilaton geometry to be uniquely identified. For much smaller values of the dilaton slope, the LHC signatures become similar to the 5-d ADD scenario while relaxing the astrophysical and experimental constraints. Due to the mass gap, the KK modes are produced on-shell and decay inside the LHC detector, modifying the diphoton and dilepton spectra at large invariant mass. Finally, we perform a similar analysis for the low curvature RS geometry. We present experimental limits and calculate the ultimate reach of a 14 TeV LHC for all the above scenarios.

Spin-one top partner: phenomenology  

NASA Astrophysics Data System (ADS)

Cai, Cheng, and Terning (CCT) suggested a model in which the left-handed top quark is identified with a gaugino of an extended gauge group, and its superpartner is a spin-1 particle. We perform a phenomenological analysis of this model, with a focus on the spin-1 top partner, which we dub the "swan". We find that precision electroweak fits, together with direct searches for Z ' bosons at the LHC, place a lower bound of at least about 4.5 TeV on the swan mass. An even stronger bound, 10 TeV or above, applies in most of the parameter space, mainly due to the fact that the swan is typically predicted to be significantly heavier than the Z '. We find that the 125 GeV Higgs can be easily accommodated in this model with non-decoupling D-terms. In spite of the strong lower bound on the swan mass, we find that corrections to Higgs couplings to photons and gluons induced by swan loops are potentially observable at future Higgs factories. We also briefly discuss the prospects for discovering a swan at the proposed 100 TeV pp collider.
