    studies is both gradient and non-gradient optimization techniques were used to find the global optimum point. The second part of this study includes investigation of the possibility of weakening the shock strength and the reduction of far field signature by using off-body energy addition. The main obstacle for flying supersonically over land is the detrimental effects of sonic boom on general public and structures. The shock waves generated from various parts of an aircraft flying at supersonic speed, coalesce to form a classic sonic boom acoustic signature, 'N' wave associated with the sonic boom on the ground. High pressure was imposed on certain parts of the computational domain to simulate the pulsed laser effects, and then the propagation and interaction of this pulsed shock with shock waves generated from the diamond shaped model were investigated. Optimization of the location and the power of the pulsed shock were achieved using the non-gradient optimization technique. The main contribution of this study is the optimization of the parameters of pulsed shock.

    Ultra-high energy cosmic rays generate extensive air showers in Earth's atmosphere. A standard approach to reconstruct the energy of an ultra-high energy cosmic rays is to sample the lateral profile of the particle density on the ground of the air shower with an array of surface detectors. For cosmic rays with large inclinations, this reconstruction is based on a model of the lateral profile of the muon density observed on the ground, which is fitted to the observed muon densities in individual surface detectors. The best models for this task are derived from detailed Monte-Carlo simulations of the air shower development. We present a phenomenological parametrization scheme which allows to derive a model of the average lateral profile of the muon density directly from a fit to a set of individual Monte-Carlo simulated air showers. The model reproduces the detailed simulations with a high precision. As an example, we generate a muon density model which is valid in the energy range 10 18 eV < E < 10 20 eV and the zenith angle range 60°<θ<90°. We will further demonstrate a way to speed up the simulation of such muon profiles by three orders of magnitude, if only the muons in the shower are of interest.

    Photovoice is a powerful research method that employs participant photography for advancing voice, knowledge, and transformative change among groups historically or currently marginalized. Paradoxically, this research method risks exploitation of participant voice because of weak methodology to method congruence. The purposes of this retrospective article are to revisit current interdisciplinary research using photovoice and to suggest how to advance photovoice by improving methodology-method congruence. Novel templates are provided for improving the photovoice process across phenomenological, grounded theory, and critical theory methodologies.

    Dynamic responses of a multi-storey building without or with a sliding base-isolation device for ground shock induced by an in-tunnel explosion are numerically analyzed.The effect of an adjacent tunnel in between the building and the explosion tunnel,which affects ground shock propagation,is considered in the analysis.Different modeling methods,such as the eight-node equal-parametric finite element and mass-lumped system,are used to establish the coupling model consisting of the two adjacent tunnels,the surrounding soil medium with the Lysmer viscous boundary condition,and the multi-storey building with or without the sliding base-isolation device.In numerical calculations,a continuous friction model,which is different from the traditional Coulomb friction model,is adopted to improve the computational efficiency and reduce the accumulated errors.Some example analyses are subsequently performed to study the response characteristics of the building and the sliding base-isolation device to ground shock.The effect of the adjacent tunnel in between the building and the explosion tunnel on the ground shock wave propagation is also investigated.The final conclusions based on the numerical results will provide some guidance in engineering practice.

    The energy levels of the ground state bands of even-even plutonium-isotopes are studied according to the variable moment of inertia (VMI), variable moment of inertia nuclear softness (VMINS) and nuclear softness (NS) models. In general, the NS3 model leads to more reasonable results than the others. The backbending phenomena in these were described and discussed. The calculations of the transition probabilities B(E2) show that the effect of addition of each neutron pair on the deformation parameter (BETA) is very small. Furthermore, the proton and neutron effective charges are found to be e sub = 0.48 eb and e-v =0.33 eb.

  9. Body Awareness: a phenomenological inquiry into the common ground of mind-body therapies

    Directory of Open Access Journals (Sweden)

    Silow Theresa

    2011-04-01

    Full Text Available Abstract Enhancing body awareness has been described as a key element or a mechanism of action for therapeutic approaches often categorized as mind-body approaches, such as yoga, TaiChi, Body-Oriented Psychotherapy, Body Awareness Therapy, mindfulness based therapies/meditation, Feldenkrais, Alexander Method, Breath Therapy and others with reported benefits for a variety of health conditions. To better understand the conceptualization of body awareness in mind-body therapies, leading practitioners and teaching faculty of these approaches were invited as well as their patients to participate in focus groups. The qualitative analysis of these focus groups with representative practitioners of body awareness practices, and the perspectives of their patients, elucidated the common ground of their understanding of body awareness. For them body awareness is an inseparable aspect of embodied self awareness realized in action and interaction with the environment and world. It is the awareness of embodiment as an innate tendency of our organism for emergent self-organization and wholeness. The process that patients undergo in these therapies was seen as a progression towards greater unity between body and self, very similar to the conceptualization of embodiment as dialectic of body and self described by some philosophers as being experienced in distinct developmental levels.

  10. Detecting plant metabolic responses induced by ground shock using hyperspectral remote sensing and physiological contact measurements

    1996-12-03

    A series of field experiments were done to determine if ground shock could have induced physiological responses in plants and if the level of the response could be observed. The observation techniques were remote sensing techniques and direct contact physiological measurements developed by Carter for detecting pre-visual plant stress. The remote sensing technique was similar to that used by Pickles to detect what appeared to be ground shock induced plant stress above the 1993 Non Proliferation Experiment`s underground chemical explosion. The experiment was designed to provide direct plant physiological measurements and remote sensing ratio images and from the same plants at the same time. The simultaneous direct and remote sensing measurements were done to establish a ground truth dataset to compare to the results of the hyperspectral remote sensing measurements. In addition, the experiment was designed to include data on what was thought to be the most probable interfering effect, dehydration. The experimental design included investigating the relative magnitude of the shock induced stress effects compared to dehydration effects.

    Kmetyk, L.N.; Yarrington, P.

    1990-08-01

    Calculations have been performed with the HULL hydrocode to study ground shock effects for multiple earth penetrator weapon (EPW) bursts in hexagonal-close-packed (HCP) arrays. Several different calculational approaches were used to treat this problem. The first simulations involved two-dimensional (2D) calculations, where the hexagonal cross-section of a unit-cell in an effectively-infinite HCP array was approximated by an inscribed cylinder. Those calculations showed substantial ground shock enhancement below the center of the array. To refine the analysis, 3D unit-cell calculations were done where the actual hexagonal cross-section of the HCP array was modelled. Results of those calculations also suggested that the multiburst array would enhance ground shock effects over those for a single burst of comparable yield. Finally, 3D calculations were run in which an HCP array of seven bursts was modelled explicitly. In addition, the effects of non-simultaneity were investigated. Results of the seven-burst HCP array calculations were consistent with the unit-cell results and, in addition, provided information on the 3D lethal contour produced by such an array.

    Amphetamines are considered as narcotics in France. Their use induces modifications of the central nervous system and of the cardiovascular, respiratory and urinary systems by a sympathomimetic indirect effect. Here is reported the observation of a young woman who absorbed amphetamines causing a cardiogenic shock on a ground of acute myocarditis. The constitution of haemodynamic, respiratory and neurologic distresses lead to the endotracheal intubation of the patient. The haemodynamic status remaining shaky, despite the use of vasoactive drugs, a circulatory assistance by intra-aortic counter pulsation balloon was carried out. The initial echocardiography showed a left ventricular ejection fraction lower than 20%. Amphetamine's toxicity mechanisms still remain complicated; on cardiovascular plan, some cases of coronary artery spasm have been described. The coronarography, not accomplished immediately, was normal. Toxicological samples revealed an abnormally high amphetamines concentration. The severity of the cardiac attack was amplified by a Mycoplasma pneumoniae myocarditis. There was a positive evolution in eight days. Intoxication and infection can difficultly be dissociated in this case of cardiogenic shock.

    Available spectral data for solar energetic particles (SEPs) measured near the Earth's orbit (GOES-13) and on the terrestrial surface (polar neutron monitors) on 6 January 2014 are analyzed. A feature of this solar proton event (SPE) and weak ground-level enhancement (GLE) is that the source was located behind the limb. For the purpose of comparison, we also use the Advanced Composition Explorer (ACE) data on sub-relativistic electrons and GOES-13 measurements of a strong and extended proton event on 8 - 9 January 2014. It was found that the surface observations at energies {>} 433 MeV and GOES-13 data at {>} 30 - {>} 700 MeV may be satisfactorily reconciled by a power-law time-of-maximum (TOM) spectrum with a characteristic exponential tail (cutoff). Some methodological difficulties of spectrum determination are discussed. Assuming that the TOM spectrum near the Earth is a proxy of the spectrum of accelerated particles in the source, we critically consider the possibility of shock acceleration to relativistic energies in the solar corona. Finally, it is suggested to interpret the observational features of this GLE under the assumption that small GLEs may be produced by shocks driven by coronal mass ejections. However, the serious limitations of such an approach to the problem of the SCR spectrum prevent drawing firm conclusions in this controversial field.

    The magnetic dipole and electric quadrupole moments of the ground states of /sup 148/Pm and /sup 210/Bi are evaluated with phenomenological wave functions derived from ..beta..-decay studies published in previous works. It is found that these wave functions account satisfactorily for the experimental data of both nuclear moments of the /sup 210/Bi ground state. In the case of /sup 148/Pm, while the calculated value of the electric quadrupole moment is not inconsistent with the experimental data, a strong disagreement between theory and experiment is found for the magnetic dipole moment. We attribute this failure to the use of a too small configuration space for the expansion of the nuclear wave function of /sup 148/Pm.

    We have completed computer simulations that model shock effects in the venusian atmosphere caused during the passage of two cometlike bodies 100 m and 1000 m in diameter and an asteroidlike body 10 km in diameter. Our objective is to examine hypervelocity-generated shock effects in the venusian atmosphere for bodies of different types and sizes in order to understand the following: (1) their deceleration and depth of penetration through the atmosphere; and (2) the onset of possible ground-surface shock effects such as splotches, craters, and ejecta formations. The three bodies were chosen to include both a range of general conditions applicable to Venus as well as three specific cases of current interest. These calculations use a new multiphase computer code (DICE-MAZ) designed by California Research & Technology for shock-dynamics simulations in complex environments. The code was tested and calibrated in large-scale explosion, cratering, and ejecta research. It treats a wide range of different multiphase conditions, including material types (vapor, melt, solid), particle-size distributions, and shock-induced dynamic changes in velocities, pressures, temperatures (internal energies), densities, and other related parameters, all of which were recorded in our calculations.

    Helicopter emergency medical services (HEMS) extend the reach of a tertiary care center significantly. However, its role in septic patients is unclear. Our study was performed to clarify the role of HEMS in severe sepsis and septic shock. This is a single-center retrospective cohort study. This study was performed at Mayo Clinic, Rochester, MN, in years 2007-2009. This study included a total of 181 consecutive adult patients admitted to the medical intensive care unit meeting criteria for severe sepsis or septic shock within 24 h of admission and transported from an acute care facility by a helicopter or ground ambulance. The primary predictive variable was the mode of transport. Multiple demographic, clinical, and treatment variables were collected and analyzed with univariate analysis followed by multivariate analysis. The patients transported by HEMS had a significantly faster median transport time (1.3 versus 1.7 h, p ground. Distance traveled was not an independent predictor of hospital mortality on multivariate analysis. HEMS transport is associated with faster transport time, carries sicker patients, and is associated with higher hospital mortality compared with ground ambulance services for patients with severe sepsis or septic shock.

  5. Propagation of interplanetary shock excited ultra low frequency (ULF) waves in magnetosphere-ionosphere-atmosphere——Multi-spacecraft “Cluster” and ground-based magnetometer observations

    Institute of Scientific and Technical Information of China (English)

    2010-01-01

    The ultra low frequency (ULF) wave in magnetosphere can act as an important means for solar wind energy inward transmission.This paper quantitatively analyzes the propagation process of the ULF wave triggered by the interplanetary shock propagating from inner magnetosphere equatorial plane along magnetic field lines to the top of the ionosphere and below ionosphere propagating process and establishes a relatively complete magnetosphere-ionosphere-atmosphere propagation model which can be used to study the relationship between the amplitude of the ULF waves triggered by the interplanetary shock wave in magnetospheric space and the magnetic effect caused by the ULF waves.After a comparison with recent observations,we found that: in the event during November 7,2004 that an interplanetary shock wave interacted with the magnetosphere,Cluster satellites observed that electric field fluctuations and the band-pass filtered result of ground stations meridional component had similar characteristics.Comparing with the geomagnetic measurement near the footprints,we found that the electric field disturbance in the magnetosphere spread along the ground magnetic field lines in the form of the ULF waves and changed into geomagnetic disturbance.The result reveals that the ULF wave is in contact with the ground geomagnetic observation.The ULF waves couple with ionized components in ionosphere and spread to the ground in the form of electromagnetic waves.In this research,we believe that the magnetosphere,ionosphere and ground magnetic effects caused by interplanetary shock wave are the same physical phenomena responding in different locations.Based on the overall consideration of entire electromagnetic response to the interplanetary shock wave,we found that the correlation between CLUSTER multi-satellite observation and geomagnetic station observation is due to the ULF wave propagated in magnetosphere-ionosphere-atmosphere system,and we quantitatively interpreted this response

    Fischer, C T

    1979-04-01

    Although there is growing openness to tailoring of assessment procedures and reports to the particular client, these efforts typically have been sporadic and incomplete. This article reviews a systematic approach to individualized assessment, one whose practices are referred to as collaborative, contextual, and interventional. Clinical examples of these practices are presented in terms of their grounding in phenomenological psychology. Prior to that, themes such as intentionality, situatedness, dialectics, structuralism, and hermeneutics are introduced briefly. Phenomenological psychology as such is not seen here as necessary for all individualized practices, but it is seen as a critical touchpoint for development of theory and further practices.

  7. Quantum Gravity and Phenomenological Philosophy

    Science.gov (United States)

    Rosen, Steven M.

    2008-06-01

    The central thesis of this paper is that contemporary theoretical physics is grounded in philosophical presuppositions that make it difficult to effectively address the problems of subject-object interaction and discontinuity inherent to quantum gravity. The core objectivist assumption implicit in relativity theory and quantum mechanics is uncovered and we see that, in string theory, this assumption leads into contradiction. To address this challenge, a new philosophical foundation is proposed based on the phenomenology of Maurice Merleau-Ponty and Martin Heidegger. Then, through the application of qualitative topology and hypernumbers, phenomenological ideas about space, time, and dimension are brought into focus so as to provide specific solutions to the problems of force-field generation and unification. The phenomenological string theory that results speaks to the inconclusiveness of conventional string theory and resolves its core contradiction.

    2017-04-01

    On August 24, 2016 an Mw 6.0 earthquake struck Central Apennines (Italy) resulting in 299 fatalities, 388 injuries and about 3000 homeless in Amatrice wider area. Normal faulting surface ruptures along the western slope of Mt Vettore along with provided focal mechanisms demonstrated a NW-SE striking and SE dipping causative normal fault. The dominant building types in the affected area are unreinforced masonry (URM) and reinforced concrete (RC) buildings. Based on our macroseismic survey in the affected area immediately after the earthquake, RC buildings suffered non-structural damage including horizontal cracking of infill and internal partition walls, detachment of infill walls from the surrounding RC frame and detachment of large plaster pieces from infill walls as well as structural damage comprising soft story failure, symmetrical buckling of rods, compression damage at midheight of columns and bursting of over-stressed columns resulting in partial or total collapse. Damage in RC buildings was due to poor quality of concrete, inadequacy of reinforcement, inappropriate foundation close to the edge of slopes leading to differential settlements, poor workmanship and the destructive effect of vertical ground motions. Damage in URM buildings ranged from cracks and detachment of large plaster pieces from load-bearing walls to destruction due to poor workmanship with randomly placed materials bound by low-strength mortars, the effect of the vertical ground motion, inadequate repair and/or strengthening after previous earthquakes as well as inadequate interventions, additions and extensions to older URM buildings. During field surveying, the authors had the opportunity to observe damage induced not only by the main shock but also by its largest aftershocks (Mw 4.5-5.3) during the first three days of the aftershock sequence (August 24-26). Bearing in mind that: (a) soil conditions in foundations of the affected villages were more or less similar, (b) building damage

    Full Text Available This paper presents a bi-constructivist approach to the study of animal life, which is opposed to the realist-Cartesian paradigm in which most ethology operates. The method is elaborated through the examples of a knot-tying orangutan in a Paris zoo and chile-eating cats in a New York apartment. We show that, when grounded in the operational framework of the phenomenological approach, the interpretation of animal life acquires a much more robust character than is usually supposed.

    2013-02-10

    We reexamine nonlinear diffusive shock acceleration (DSA) at cosmological shocks in the large-scale structure of the universe, incorporating wave-particle interactions that are expected to operate in collisionless shocks. Adopting simple phenomenological models for magnetic field amplification (MFA) by cosmic-ray (CR) streaming instabilities and Alfvenic drift, we perform kinetic DSA simulations for a wide range of sonic and Alfvenic Mach numbers and evaluate the CR injection fraction and acceleration efficiency. In our DSA model, the CR acceleration efficiency is determined mainly by the sonic Mach number M{sub s} , while the MFA factor depends on the Alfvenic Mach number and the degree of shock modification by CRs. We show that at strong CR modified shocks, if scattering centers drift with an effective Alfven speed in the amplified magnetic field, the CR energy spectrum is steepened and the acceleration efficiency is reduced significantly, compared to the cases without such effects. As a result, the postshock CR pressure saturates roughly at {approx}20% of the shock ram pressure for strong shocks with M{sub s} {approx}> 10. In the test-particle regime (M{sub s} {approx}< 3), it is expected that the magnetic field is not amplified and the Alfvenic drift effects are insignificant, although relevant plasma physical processes at low Mach number shocks remain largely uncertain.

    In this study, the rupture process of the main shock of the Kumamoto earthquake, particularly the generation of strong ground motions in the frequency range relevant to structural damage, was investigated based on the inversion of strong ground motions. Strong-motion records in the near-source region were mainly utilized because the authors were interested in the generation mechanism of damaging ground motions in the near-source region. Empirical Green's functions (EGFs) were applied to avoid uncertainty in the subsurface structure model. Four cases of inversions with different combinations of small events were used to investigate the dependence of the inversion results on the selection of the small events. It was found that the dependence of the final slip distribution and peak slip velocity distribution on the selection of the EGF events is small. The results clearly indicate that a region of significantly large slip and slip velocity existed approximately 15 km northeast of the hypocenter. However, no "asperity" was observed between the hypocenter and Mashiki. Thus, it is not appropriate to conclude that the large-amplitude pulse-like ground motion in Mashiki was generated by the forward-directivity effect associated with the rupture of an asperity. As far as the source effect is concerned, the ground motion in Mashiki cannot be interpreted as the worst case scenario. On the other hand, the rupture of the "asperity" 15 km northeast of the hypocenter should have caused significantly large ground motions in regions close to the asperity. The significant damage of highway bridges in the region can potentially be attributed to the rupture of the asperity. The result of this study was compared with an inversion result obtained from numerical Green's functions for a layered half-space. The two results share the main features in spite of the difference of the Green's functions and stations used. Therefore, it can be concluded that these two source models capture the

  19. "Phenomenology" and qualitative research methods.

    Nakayama, Y

    1994-01-01

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

  20. Phenomenology as a resource for patients.

    Science.gov (United States)

    Carel, Havi

    2012-04-01

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

I show how this framework can be used to associate phenomenological structures with neuro-computational structures, and vice-versa.

    CERN Document Server

    De la Macorra, A

    1995-01-01

    We consider the low energy phenomenology of superstrings. In particular we analyse supersymmetry breaking via gaugino condensate and we compare the phenomenology of the two different approaches to stabilize the dilaton field. We study the cosmological constant problem and we show that it is possible to have supersymmetry broken and zero cosmological constant. Finally, we discuss the possibility of having an inflationary potential. Requiring that the potential does not destabilize the dilaton field imposes an upper limit to the density fluctuations which can be consistent with the COBE data.

  6. Elastic scattering phenomenology

    Energy Technology Data Exchange (ETDEWEB)

    Mackintosh, R.S. [The Open University, School of Physical Sciences, Milton Keynes (United Kingdom)

    2017-04-15

    We argue that, in many situations, fits to elastic scattering data that were historically, and frequently still are, considered ''good'', are not justifiably so describable. Information about the dynamics of nucleon-nucleus and nucleus-nucleus scattering is lost when elastic scattering phenomenology is insufficiently ambitious. It is argued that in many situations, an alternative approach is appropriate for the phenomenology of nuclear elastic scattering of nucleons and other light nuclei. The approach affords an appropriate means of evaluating folding models, one that fully exploits available empirical data. It is particularly applicable for nucleons and other light ions. (orig.)

  7. Diffusive Shock Acceleration at Cosmological Shock Waves

    CERN Document Server

    Kang, Hyesung

    2012-01-01

    We reexamine nonlinear diffusive shock acceleration (DSA) at cosmological shocks in the large scale structure of the Universe, incorporating wave-particle interactions that are expected to operate in collisionless shocks. Adopting simple phenomenological models for magnetic field amplification (MFA) by cosmic-ray (CR) streaming instabilities and Alfv'enic drift, we perform kinetic DSA simulations for a wide range of sonic and Alfv'enic Mach numbers and evaluate the CR injection fraction and acceleration efficiency. In our DSA model the CR acceleration efficiency is determined mainly by the sonic Mach number Ms, while the MFA factor depends on the Alfv'enic Mach number and the degree of shock modification by CRs. We show that at strong CR modified shocks, if scattering centers drift with an effective Alfv'en speed in the amplified magnetic field, the CR energy spectrum is steepened and the acceleration efficiency is reduced significantly, compared to the cases without such effects. As a result, the postshock C...

  8. Husserl, phenomenology and nursing.

    Science.gov (United States)

    Paley, J

    1997-07-01

    Discussions of phenomenological research in nursing consistently appeal to either Husserl or Heidegger in justifying the technical and conceptual resources they deploy. This paper focuses on Husserl, and examines the relationship between his phenomenology and the accounts of it that are to be found in the nursing literature. Three central ideas are given particular attention: the phenomenological reduction, phenomena, and essence. It is argued that nurse researchers largely misunderstand these concepts and that, as a result, their version of Husserl's philosophy bears little resemblance to the original. A further consequence is that the project of identifying the 'essential structure' of a phenomenon, typically adopted by the nurse researchers who cite Husserl as an authority, comes close to being unintelligible. It is suggested that, while the methods used in 'phenomenological' nursing research may still have some legitimacy, they cannot achieve what they are alleged to achieve, and they should be detached from the framework of Husserlian ideas and terminology which is supposed to justify them.

    Ben-dor, Gabi

    2007-01-01

    This book provides a comprehensive state-of-the-knowledge description of the shock wave reflection phenomena from a phenomenological point of view. The first part is a thorough introduction to oblique shock wave reflections, presenting the two major well-known reflection wave configurations, namely, regular (RR) and Mach (MR) reflections, the corresponding two- and three-shock theories, their analytical and graphical solution and the proposed transition boundaries between these two reflection-wave configurations. The second, third and fourth parts describe the reflection phenomena in steady, pseudo-steady and unsteady flows, respectively. Here, the possible specific types of reflection wave configurations are described, criteria for their formation and termination are presented and their governing equations are solved analytically and graphically and compared with experimental results. The resolution of the well-known von Neumann paradox and a detailed description of two new reflection-wave configurations - t...

  15. Phenomenological theory of mortality

    Science.gov (United States)

    Azbel, Mark Ya.

    1997-09-01

    Extensive demographic studies relate aging to the increase in mortality, terminated by the species-specific lifespan limit. Meanwhile, recent experiments demonstrate that medfly mortality decreases at older ages, and challenge a limited lifespan paradigm. This paper proves that there exists a genetically programmed probability to die at any given age, and presents its phenomenological theory. The implications of the universal mortality law crucially depend on the cohort heterogeneity. For relatively high heterogeneity the law predicts unitarily vanishing old age mortality; this is verified with medfly data. For relatively low heterogeneity it predicts a precipitous drop in mortality fluctuations in old age. This is verified with demographic data. If comprehensive studies verify a species-specific characteristic age, then that age may be genetically manipulated. If the studies verify a unitary law of mortality, the results may be generalized to all species. A phenomenological model of mortality is presented.

  16. Resonant Diphoton Phenomenology Simplified

    CERN Document Server

    Panico, Giuliano; Wulzer, Andrea

    2016-01-01

    A framework is proposed to describe resonant diphoton phenomenology at hadron colliders in full generality. It can be employed for a comprehensive model-independent interpretation of the experimental data. Within the general framework, few benchmark scenarios are defined as representative of the various phenomenological options and/or of motivated new physics scenarios. Their usage is illustrated by performing a characterization of the 750 GeV excess, based on a recast of available experimental results. We also perform an assessment of which properties of the resonance could be inferred, after discovery, by a careful experimental study of the diphoton distributions. These include the spin J of the new particle and its dominant production mode. Partial information on its CP-parity can also be obtained, but only for J >= 2. The complete determination of the resonance CP properties requires studying the pattern of the initial state radiation that accompanies the resonance production.

    Science.gov (United States)

    Goranson, Ted; Cardier, Beth; Devlin, Keith

    2015-12-01

    We approach a well-known problem: how to relate component physical processes in biological systems to governing imperatives in multiple system levels. The intent is to further practical tools that can be used in the clinical context. An example proposes a formal type system that would support this kind of reasoning, including in machines. Our example is based on a model of the connection between a quality of mind associated with creativity and neuropsychiatric dynamics: constructing narrative as a form of conscious introspection, which allows the manipulation of one's own driving imperatives. In this context, general creativity is indicated by an ability to manage multiple heterogeneous worldviews simultaneously in a developing narrative. 'Narrative' in this context is framed as the organizing concept behind rational linearization that can be applied to metaphysics as well as modeling perceptive dynamics. Introspection is framed as the phenomenological 'tip' that allows a perceiver to be within experience or outside it, reflecting on and modifying it. What distinguishes the approach is the rooting in well founded but disparate disciplines: phenomenology, ontic virtuality, two-sorted geometric logics, functional reactive programming, multi-level ontologies and narrative cognition. This paper advances the work by proposing a type strategy within a two-sorted reasoning system that supports cross-ontology structure. The paper describes influences on this approach, and presents an example that involves phenotype classes and monitored creativity enhanced by both soft methods and transcranial direct-current stimulation. The proposed solution integrates pragmatic phenomenology, situation theory, narratology and functional programming in one framework.

    We study the phenomenological implications of Finite Unified Theories (FUTs). In particular we look at the predictions for the lightest Higgs mass and the s-spectra of two all-loop finite models with SU(5) as gauge group. We also consider a two-loop finite model with gauge group SU(3){sup 3}, which is finite if and only if there are exactly three generations. In this latter model we concetrate here only on the predictions for the third generation of quark masses.

Besides the more historical studies, the internal ones on Husserl alone and the external ones attempting to clarify his role in the more general context of the developing mathematics and logic, Husserl,s phenomenology offers also a systematically rich but little researched area of investigation.

    In this article I propose a method of interviewing for descriptive phenomenological research that offers an explicit, theoretically based approach for researchers. My approach enables application of descriptive phenomenology as a total method for research, and not one just focused on data analysis. This structured phenomenological approach to interviewing applies questions based on themes of experience contextualization, apprehending the phenomenon and its clarification. The method of questioning employs descriptive and structural questioning as well as novel use of imaginative variation to explore experience. The approach will help researchers understand how to undertake descriptive phenomenological research interviews.

    Full Text Available In this paper I will examine Husserl’s attempt to establish a ground for science with the so called transcendental reduction. This will entail both an identification of the problems that Husserl was attempting to solve as well as a careful analysis of Husserl’s account of his methodology. I will then examine how Derrida’s reading, which affirms the phenomenological project in many of its essential aspects, begins to signal a subtle yet ultimately radical disagreement. This disagreement will have lasting implications for our understanding of the possibilities designated by the transcendental method in Husserl’s thinking.

    2001-01-01

    Experimental results on ternary fission of sup 2 sup 5 sup 2 Cf suggest the existence of a short-lived quasi-molecular state. We present a three-center phenomenological model able to explain such a state by producing a new minimum in the deformation energy at a separation distance very close to the touching point. The shape parametrization chosen by us allows to describe the essential geometry of the systems in terms of one independent coordinate, namely, the distance between the heavy fragment centers. The shell correction (also treated phenomenologically) only produces quantitative effects; qualitatively it is not essential for the new minimum. Half-lives of some quasi-molecular states which could be formed in sup 1 sup 0 B accompanied fission of sup 2 sup 3 sup 6 U, sup 2 sup 3 sup 6 Pu, sup 2 sup 4 sup 6 Cm, sup 2 sup 5 sup 2 Cf, sup 2 sup 5 sup 2 sup , sup 2 sup 5 sup 6 Fm, sup 2 sup 5 sup 6 sup , sup 2 sup 6 sup 0 No, and sup 2 sup 6 sup 2 Rf are roughly estimated.

  10. Phenomenology and Neuroaesthetics

    Directory of Open Access Journals (Sweden)

    Elio Franzini

    2015-05-01

    Full Text Available Phenomenology is not the simple description of a fact, but rather the description of an intentional immanent moment, and it presents itself as a science of essences, and not of matter of facts. The Leib, the lived body of the phenomenological tradition, is not a generic corporeal reality, but rather an intentional subject, a transcendental reference point, on the base of which the connections between physical body and psychic body should be grasped. So, the reduction of empathy to mirror neurons amounts to an “objectivisation”, with the consequent absolutisation of a process that is a function of the Leib as intentional subject, not as a physical reality. The main task of the philosophical research, bracketed by the new “neuro” researches, thus emphasizing their theoretical limits as soon as they depart from experimental enquiries, is then to understand the conditions of possibility of cognitive procedures, that is to say, in other words, the genesis of consciousness, that in aesthetics becomes “the genesis of aesthetic consciousness”. Interdisciplinarity is already an ancient and out of fashion word, now it is the time of “dialogue”, being aware however that the “logoi” not always require synthesis, and that the unity of the corporeal reality implies, as Husserl emphasizes, very different descriptive behaviours.

  11. A Phenomenology of Islands

    Directory of Open Access Journals (Sweden)

    Pete Hay

    2006-05-01

    Full Text Available The question is posed: is a coherent theory of islandness – nissology – possible? Faultlines within constructions of islands and islandness are noted. Some of these axes of contestation have remained latent but have the potential to be sharply divisive. Three of the identified faultlines are examined – the nature of the island ‘edge’, the import for questions of island memory and identity of massive inward and outward movements of people, and the appropriation of island ‘realness’ by those for whom ‘island’ best functions as metaphor. A case is made for the excision of the latter from the purview of island studies. Despite apparent irreconcilability within island studies’ emerging faultlines, it is argued that place theory does constitute a theoretical framing that can work for island studies. Following a brief overview of the faultlines that also exist within place studies, it is noted that the difference-respecting and identity focused nature of phenomenology of place is particularly apposite for island studies, and the paper concludes with a consideration of what a phenomenology of islands might look like.

    Kaufman's ground-breaking work in the 1980s introduced the phenomenology of disability. In my commentary, I describe phenomenology as a philosophy of understanding the world around us and as a methodology for understanding the lived experiences of patients with life-changing disabilities.

As such, I agree with Kaufman that phenomenology can help health care professionals expand their understanding of patient experiences to provide a fuller and richer, holistic response to care.

    The focus of this paper draws on the thinking of Husserl, Dilthey and Heidegger to identify elements of the phenomenological movement that can provide focus and direction for qualitative research in nursing. The authors interpret this tradition in two ways: emphasizing the possible complementarity of phenomenology, hermeneutics and existentialism, and demonstrating how these emphases ask for grounding, reflexivity and humanization in qualitative research. The paper shows that the themes of grounding, reflexivity and humanization are particularly important for nursing research.

    This article summarises the status of the solar neutrino oscillation phenomenology at the end of 2002 in the light of the SNO and KamLAND results. We first present the allowed areas obtained from global solar analysis and demonstrate the preference of the solar data towards the large-mixing-angle (LMA) MSW solution. A clear confirmation in favour of the LMA solution comes from the KamLAND reactor neutrino data. the KamLAND spectral data in conjunction with the global solar data further narrows down the allowed LMA region and splits it into two allowed zones - a low $ m^{2}$ region (low-LMA) and high $ m^{2}$ region (high-LMA). We demonstrate through a projected analysis that with an exposure of 3 kton-year (kTy) KamLAND can remove this ambiguity.

  19. Fitting the Phenomenological MSSM

    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.

  20. Phenomenological Quantum Gravity

    These notes summarize a set of lectures on phenomenological quantum gravity which one of us delivered and the other attended with great diligence. They cover an assortment of topics on the border between theoretical quantum gravity and observational anomalies. Specifically, we review non-linear relativity in its relation to loop quantum gravity and high energy cosmic rays. Although we follow a pedagogic approach we include an open section on unsolved problems, presented as exercises for the student. We also review varying constant models: the Brans-Dicke theory, the Bekenstein varying $\\alpha$ model, and several more radical ideas. We show how they make contact with strange high-redshift data, and perhaps other cosmological puzzles. We conclude with a few remaining observational puzzles which have failed to make contact with quantum gravity, but who knows... We would like to thank Mario Novello for organizing an excellent school in Mangaratiba, in direct competition with a very fine beach indeed.

  1. Phenomenology of atmospheric neutrinos

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available The detection of astrophysical neutrinos, certainly a break-through result, introduced new experimental challenges and fundamental questions about acceleration mechanisms of cosmic rays. On one hand IceCube succeeded in finding an unambiguous proof for the existence of a diffuse astrophysical neutrino flux, on the other hand the precise determination of its spectral index and normalization requires a better knowledge about the atmospheric background at hundreds of TeV and PeV energies. Atmospheric neutrinos in this energy range originate mostly from decays of heavy-flavor mesons, which production in the phase space relevant for prompt leptons is uncertain. Current accelerator-based experiments are limited by detector acceptance and not so much by the collision energy. This paper recaps phenomenological aspects of atmospheric leptons and calculation methods, linking recent progress in flux predictions with particle physics at colliders, in particular the Large Hadron Collider.

  2. Management practice: phenomenological approach

    2005-01-01

    Full Text Available This work has the aim of understanding the lived experiences by managers in relation to organizational changes in an enterprise in the food area, located in the State of Rio Grande do Sul, Brazil. The role of managers has been constantly evaluated and their capacity of continuous learning and also the ability of transforming the learning in good organizational results is reacquired every instant. In this work, my intention is to show, using an interpretative analysis, real and practical situations, from lived experiences. The methodological way followed was the hermeneutic phenomenological approach, trying to give a global and a contextual treatment to the theme. The results achieved offer subsides for a new look over the management practice and point out the importance of the study of what is lived, as an inspiration source for the strategic decisions in the enterprises.

  3. Corrugation of relativistic magnetized shock waves

    Lemoine, M; Gremillet, L

    2016-01-01

    As a shock front interacts with turbulence, it develops corrugation which induces outgoing wave modes in the downstream plasma. For a fast shock wave, the incoming wave modes can either be fast magnetosonic waves originating from downstream, outrunning the shock, or eigenmodes of the upstream plasma drifting through the shock. Using linear perturbation theory in relativistic MHD, this paper provides a general analysis of the corrugation of relativistic magnetized fast shock waves resulting from their interaction with small amplitude disturbances. Transfer functions characterizing the linear response for each of the outgoing modes are calculated as a function of the magnetization of the upstream medium and as a function of the nature of the incoming wave. Interestingly, if the latter is an eigenmode of the upstream plasma, we find that there exists a resonance at which the (linear) response of the shock becomes large or even diverges. This result may have profound consequences on the phenomenology of astrophys...

Based on the location along the meteor trail where the infrasound signal originates, we find most signals are associated with cylindrical shocks, with ...

  5. [Phenomenology of dreams].

    2011-10-01

    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).

  6. Phenomenological consequences of supersymmetry

    Energy Technology Data Exchange (ETDEWEB)

    Hinchliffe, I.; Littenberg, L.

    1982-01-01

    This report deals with the phenomenological consequences of supersymmetric theories, and with the implications of such theories for future high energy machines. It is concerned only with high energy predictions of supersymmetry; low energy consequences (for example in the K/sub o/anti K/sub o/ system) are discussed in the context of future experiments by another group, and will be mentioned briefly only in the context of constraining existing models. However a brief section is included on the implication for proton decay, although detailed experimental questions are not discussed. The report is organized as follows. Section I consists of a brief review of supersymmetry and the salient features of existing supersymmetric models; this section can be ignored by those familiar with such models since it contains nothing new. Section 2 deals with the consequences for nucleon decay of SUSY. The remaining sections then discuss the physics possibilities of various machines; e anti e in Section 3, ep in Section 4, pp (or anti pp) colliders in Section 5 and fixed target hadron machines in Section 6.

  7. Perspectives on string phenomenology

    Kane, Gordon; Kumar, Piyush

    2015-01-01

    The remarkable recent discovery of the Higgs boson at the CERN Large Hadron Collider completed the Standard Model of particle physics and has paved the way for understanding the physics which may lie beyond it. String/M theory has emerged as a broad framework for describing a plethora of diverse physical systems, which includes condensed matter systems, gravitational systems as well as elementary particle physics interactions. If string/M theory is to be considered as a candidate theory of Nature, it must contain an effectively four-dimensional universe among its solutions that is indistinguishable from our own. In these solutions, the extra dimensions of string/M Theory are “compactified” on tiny scales which are often comparable to the Planck length. String phenomenology is the branch of string/M theory that studies such solutions, relates their properties to data, and aims to answer many of the outstanding questions of particle physics beyond the Standard Model. This book contains perspectives on stri...

  8. The varieties of ecstasy experience: a phenomenological ethnography.

    Leneghan, Sean

    2013-01-01

    Ecstasy (MDMA) has attracted widespread attention with its association as a "recreational substance" that is concentrated in club and rave settings. This paper outlines a phenomenologically grounded ethnographic study of the experiences of ecstasy users in the Sydney, Australia, area. I espouse phenomenology as a framework for describing and understanding these experiences. A number of excerpts are presented from my primary corpus of ethnographic material. For the purposes of this paper I assemble user's reports into nine thematic areas: (1) initial reactions and peaking; (2) the rush; (3) plateau; (4) coming down/scattering; (5) love; (6) peace, love, understanding, and respect; (7) connections on ecstasy; (8) unificatory experiences; (9) returning to baseline. The typical experiences presented in these reports confirm and extend interdisciplinary approaches to understanding ecstasy. I suggest that a context-specific approach that is phenomenologically attuned to user's experiences with ecstasy can contribute to the growing body of literature undertaken in the Australian and international research community.

  14. The changing face of phenomenological research: traditional and American phenomenology in nursing.

    Science.gov (United States)

    Caelli, K

    2000-05-01

    In recent years, phenomenological researchers in nursing have become concerned about the differences between traditional European phenomenology and the way phenomenology is frequently conducted in nursing. Indeed, Crotty asserts that much of the phenomenology conducted by nurses cannot be phenomenology because it does not espouse the constructionist epistemological position regarded by Husserl as essential to phenomenology. This article explores the differences between traditional European and American phenomenology and argues that the latter approach extends the phenomenological project in valuable and meaningful ways that are particularly appropriate for the health sciences.

  15. Warped Phenomenology of Higher-Derivative Gravity

    Energy Technology Data Exchange (ETDEWEB)

    Rizzo, T.

    2004-12-06

    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.

    Science.gov (United States)

    Peckham, D. W.; Uman, M. A.; Wilcox, C. E., Jr.

    1984-01-01

    A commercial lightning-locating system (LLS) was employed in the study of lightning phenomenology in the Tampa Bay area of Florida. The LLS output included the time, location, number of strokes per flash, and initial peak magnetic field value of first strokes for lightning ground flashes lowering negative charge. Attention is given to the design and the operation of the LLS, and the experimental results. Measured properties of each of 111 storms are given in a number of tables. It was observed that the apparent motion associated with the lightning activity in storm systems was not due to the motion of the individual single-peak and multiple-peak storms but rather to the successive growth of new storms near previously active storms.

    Full Text Available It is becoming apparent in modern cognitive science that the lack of knowledge about human experiential landscape implies the loss of a very important element, perhaps the very essence. Consequently, a rather new area of research has emerged recently: an attempt at a systematic observation and study of experience. This is the so-called phenomenologically inspired research (or just phenomenological research.Part of this article aims to present this new area of research – it describes the common fundaments of the field and some of its characteristic methodological derivates, relating them to the possibility of studying decision making from the first-person point-of-view, i.e. decision making as an experiential phenomenon (and not as a neurological or behavioural process. The article also presents some of the findings phenomenological studies have led to and some theoretical reflexions encouraged by these insights.

    An essentially qualitatively description is given of the phenomena related to underground nuclear explosions (explosion of a single unit, of several units in line, and simultaneous explosions). In the first chapter are described the phenomena which are common to contained explosions and to explosions forming craters (formation and propagation of a shock-wave causing the vaporization, the fusion and the fracturing of the medium). The second chapter describes the phenomena related to contained explosions (formation of a cavity with a chimney). The third chapter is devoted to the phenomenology of test explosions which form a crater; it describes in particular the mechanism of formation and the different types of craters as a function of the depth of the explosion and of the nature of the ground. The aerial phenomena connected with explosions which form a crater: shock wave in the air and focussing at a large distance, and dust clouds, are also dealt with. (authors) [French] On donne une description essentiellement qualitative des phenomenes lies aux explosions nucleaires souterraines (explosion d'un seul engin, d'engins en ligne et explosions simultanees).

    2016-01-01

    We investigate oscillating shock waves in a tube using a higher order weakly nonlinear acoustic model. The model includes thermoviscous effects and is non isentropic. The oscillating shock waves are generated at one end of the tube by a sinusoidal driver. Numerical simulations show...... that at resonance a stationary state arise consisting of multiple oscillating shock waves. Off resonance driving leads to a nearly linear oscillating ground state but superimposed by bursts of a fast oscillating shock wave. Based on a travelling wave ansatz for the fluid velocity potential with an added 2'nd order...... polynomial in the space and time variables, we find analytical approximations to the observed single shock waves in an infinitely long tube. Using perturbation theory for the driven acoustic system approximative analytical solutions for the off resonant case are determined....

  13. Naturalizing phenomenology - A philosophical imperative.

    Science.gov (United States)

    Harney, Maurita

    2015-12-01

    Phenomenology since Husserl has always had a problematic relationship with empirical science. In its early articulations, there was Husserl's rejection of 'the scientific attitude', Merleau-Ponty's distancing of the scientifically-objectified self, and Heidegger's critique of modern science. These suggest an antipathy to science and to its methods of explaining the natural world. Recent developments in neuroscience have opened new opportunities for an engagement between phenomenology and cognitive science and through this, a re-thinking of science and its hidden assumptions more generally. This is so partly because of the shortcomings of conventional mechanistically-conceived science in dealing with complex and dynamic phenomena such as climate change, brain plasticity, the behaviour of collectives, the dynamics of various microbiological processes, etc. But it is also due to recent phenomenological scholarship focussed on the 'embodied' phenomenology of Husserl's Ideen II and Merleau Ponty's later ontology of nature which have helped to extend the insights of phenomenology beyond the narrowly 'human' to an understanding of nature (which includes the human) more generally. Thus re-contextualised, phenomenology is well placed to examine some of the assumptions that give rise to the reductionism and associated scientism which has characterised conventional science in its approach to the study of natural processes. In light of this, it might be suggested that the 'anti-science' of early articulations of phenomenology is more a hostility to the underlying assumptions of science as conventionally understood than to science itself - that it is scientism rather than science that is targeted. In this paper, I aim to show how a phenomenological naturalism might be seen as a necessary step towards the development of a non-reductionist and non-scientistic approach to scientific inquiry. A key to this is a reconceptualization of nature as inclusive of meanings and of mind. It

  14. Phenomenological aspects of mirage mediation

    Energy Technology Data Exchange (ETDEWEB)

    Loewen, Valeri

    2009-07-15

    We consider the possibility that string theory vacua with spontaneously broken supersymmetry and a small positive cosmological constant arise due to hidden sector matter interactions, known as F-uplifting/F-downlifting. We analyze this procedure in a model-independent way in the context of type IIB and heterotic string theory. Our investigation shows that the uplifting/downlifting sector has very important consequences for the resulting phenomenology. Not only does it adjust the vacuum energy, but it can also participate in the process of moduli stabilization. In addition, we find that this sector is the dominant source of supersymmetry breaking. It leads to a hybrid mediation scheme and its signature is a relaxed mirage pattern of the soft supersymmetry breaking terms. The low energy spectra exhibit distinct phenomenological properties and di er from conventional schemes considered so far. (orig.)

  15. A phenomenological approach to psychoprosthetics.

    Science.gov (United States)

    Mills, Frederick B

    2013-05-01

    The phenomenology of human embodiment can advance the practitioner's understanding of the lived human body and in particular, what it means to incorporate a prosthetic device into one's body. In order for a prosthesis to be incorporated into the lived body of the patient, the prosthesis must arguably be integrated into the body schema. This article uses the phenomenology of Maurice Merleau-Ponty and others to identify three of the necessary conditions of embodiment that determine the body schema: corporeal understanding, transparency and sensorimotor feedback. It then examines the structure of each of these conditions of embodiment and how they impact the lived body's incorporation of prostheses and other artifacts. [Box: see text].

    Experimentally, Langmuir monolayers have applications in molecular optical, electronic, and sensor devices. Traditionally, Langmuir monolayers are described by a rigid rod model where the rods interact via a Leonard-Jones potential. Here, we propose effective phenomenological models and utilize Monte Carlo simulations to analyze the phase behavior and compare with experimental isotherms.

    We study the phenomenological potential of noncommutative QED as obtained from the Seiberg-Witten limit of string theories in the presence of an external B-field. We manage to define the theory free of tachyons by embedding it into {N}=4 noncommutative super Yang-Mills and breaking supersymmetry softly by adding masses to fermions and scalars. However, this requires a fine-tuning of the soft-breaking mass and the resulting theory has massive polarization for the photon.

    In this proceeding, the phenomenology of Universal Extra Dimensions (UED), in which all the Standard Model fields propagate, is explored. We focus on models with one universal extra dimension, compactified on an S{sub 1}/Z{sub 2} orbifold. We revisit calculations of Kaluza-Klein (KK) dark matter without an assumption of the KK mass degeneracy including all possible coannihilations. We then contrast the experimental signatures of low energy supersymmetry and UED.

    In this paper I examine the dispute between Hakwan Lau, Ned Block, and David Rosenthal over the extent to which empirical results can help us decide between first-order and higher-order theories of consciousness. What emerges from this is an overall argument to the best explanation against the first-order view of consciousness and the dispelling of the mythological notion of phenomenological overflow that comes with it.

  20. Phenomenology of stochastic exponential growth

    Pirjol, Dan; Jafarpour, Farshid; Iyer-Biswas, Srividya

    2017-06-01

    Stochastic exponential growth is observed in a variety of contexts, including molecular autocatalysis, nuclear fission, population growth, inflation of the universe, viral social media posts, and financial markets. Yet literature on modeling the phenomenology of these stochastic dynamics has predominantly focused on one model, geometric Brownian motion (GBM), which can be described as the solution of a Langevin equation with linear drift and linear multiplicative noise. Using recent experimental results on stochastic exponential growth of individual bacterial cell sizes, we motivate the need for a more general class of phenomenological models of stochastic exponential growth, which are consistent with the observation that the mean-rescaled distributions are approximately stationary at long times. We show that this behavior is not consistent with GBM, instead it is consistent with power-law multiplicative noise with positive fractional powers. Therefore, we consider this general class of phenomenological models for stochastic exponential growth, provide analytical solutions, and identify the important dimensionless combination of model parameters, which determines the shape of the mean-rescaled distribution. We also provide a prescription for robustly inferring model parameters from experimentally observed stochastic growth trajectories.

  1. How I remember my parents' divorce: a phenomenological investigation.

    Stambaugh, Suzanne E; Hector, Mark A; Carr, Austin R

    2011-01-01

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

  2. Are gauge shocks really shocks?

    The existence of gauge pathologies associated with the Bona-Masso family of generalized harmonic slicing conditions is proven for the case of simple 1+1 relativity. It is shown that these gauge pathologies are true shocks in the sense that the characteristic lines associated with the propagation of the gauge cross, which implies that the name ``gauge shock'' usually given to such pathologies is indeed correct. These gauge shocks are associated with places where the spatial hypersurfaces that determine the foliation of spacetime become non-smooth.

  3. Philosophy of phenomenology: how understanding aids research.

    2012-01-01

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

  4. Diffusive shock acceleration with magnetic field amplification and Alfvenic drift

    2012-01-01

    We explore how wave-particle interactions affect diffusive shock acceleration (DSA) at astrophysical shocks by performing time-dependent kinetic simulations, in which phenomenological models for magnetic field amplification (MFA), Alfvenic drift, thermal leakage injection, Bohm-like diffusion, and a free escape boundary are implemented. If the injection fraction of cosmic-ray (CR) particles is greater than 2x10^{-4}, for the shock parameters relevant for young supernova remnants, DSA is efficient enough to develop a significant shock precursor due to CR feedback, and magnetic field can be amplified up to a factor of 20 via CR streaming instability in the upstream region. If scattering centers drift with Alfven speed in the amplified magnetic field, the CR energy spectrum can be steepened significantly and the acceleration efficiency is reduced. Nonlinear DSA with self-consistent MFA and Alfvenic drift predicts that the postshock CR pressure saturates roughly at 10 % of the shock ram pressure for strong shocks...

    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.

    We report on the phenomenological results obtained through Dihadron Fragmentation Functions related processes. In 2015, an update on the fitting techniques for the Dihadron Fragmentation Functions has led to an improved extraction of the transversity PDF and, as a consequence, the nucleon tensor charge. We discuss the impact of the determination of the latter on search for physics Beyond the Standard Model, focusing on the error treatment. We also comment on the future of the extraction of the subleading-twist PDF $e(x)$ from JLab soon-to-be-released Beam Spin Asymmetry data.

    Although the theoretical set-up of TMD evolution appears to be well established, its phenomenological implementations still require special attention, particularly as far as the interplay between perturbative and non-perturbative contributions is concerned. These issues have been extensively studied in Drell-Yan processes, where they seem to be reasonably under control. Instead, applying the same prescriptions and methodologies to Semi-Inclusive Deep Inelastic (SIDIS) processes is, at present, far from obvious. Some of the controversies related to the applications of TMD Evolution to SIDIS processes will be discussed with practical examples, exploring different kinematical configurations of SIDIS experiments.

    The present paper deals with the problematic nature of the phenomenological grasping of the consciousness of the body and its pathological modifications. The reasoning is oriented by the doctrine of Husserl of the so-called sentiments as the fundamentals of the experience of the own body. This basic approach does not only seem to be basically for a psychology of the consciousness of the body, but also to give the theoretical-conceptual structure for a great number of psychopathological modifications. Subsequent to a criticism of the conventional use of the term 'hallucination of the body' we attempt to chart elements of a scheme of the abnormal consciousness of the body.

  15. Phenomenology is not Phenomenalism. Is there such a thing as phenomenology of sport?

    Directory of Open Access Journals (Sweden)

    Jan Halák

    2014-06-01

    Full Text Available Background: The application of the philosophical mode of investigation called "phenomenology" in the context of sport. Objective: The goal is to show how and why the phenomenological method is very often misused in sport-related research. Methods: Interpretation of the key texts, explanation of their meaning. Results: The confrontation of concrete sport-related texts with the original meaning of the key phenomenological notions shows mainly three types of misuse - the confusion of phenomenology with immediacy, with an epistemologically subjectivist stance (phenomenalism, and with empirical research oriented towards objects in the world. Conclusions: Many of the discussed authors try to take over the epistemological validity of phenomenology for their research, which itself is not phenomenological, and it seems that this is because they are lacking such a methodological foundation. We believe that an authentically phenomenological analysis of sport is possible, but it must respect the basic distinctions that differentiate phenomenology from other styles of thinking.

    The neurogenic shock is a common complication of spinal cord injury, especially when localized at the cervical level. Characterized by a vasoplegia (hypotension) and bradycardia, the neurogenic shock is secondary to the damage of the sympathetic nervous system. The clinical presentation often includes tetraplegia, with or without respiratory failure. Early treatment aims to minimize the occurrence of secondary spinal cord lesions resulting from systemic ischemic injuries. Medical management consists in a standardized ABCDE approach, in order to stabilize vital functions and immobilize the spine. The hospital care includes performing imaging, further measures of neuro-resuscitation, and coordinated surgical assessment and treatment of any other injury.

  19. Cell phenomenology: The first phenomenon.

    Science.gov (United States)

    Pattee, H H

    2015-12-01

    As a broad academic discipline phenomenology may be summarized as the study from a first person point of view of what appears to subjective human conscious experience. As a historical philosophical movement phenomenology was often motivated by the belief that subjective human experience is the proper foundation of all philosophy. I explore phenomena from a broader evolutionary and physical point of view. I consider a phenomenon as the subjective consequence of a physical interaction with an individual organism. In physical terms, a phenomenon requires some form of detection or measurement. What is detected is determined by the organism, and is potentially functional for the organism as a self or subject. The concept of function has meaning only for living organisms. The classical human mind-body problem is an ill-defined complicated case of the more general epistemic subject-object problem, which at the origin of life I reduce to the primitive symbol-matter problem. I argue that the first memory-based self-replicating unit, like a cell, is the most primitive case of a necessary symbol-matter distinction. The first phenomena, which include all forms or sensing, detection, and measurement, require a subject-object distinction, called the epistemic cut. It is only because of such a subject-object distinction that populations of individual subjects can selectively adapt to their environment by heritable variations. This basic evolutionary process requires distinguishing the individual's subjective phenomena from the objective events of inexorable physical laws.

  20. For the Phenomenology of Play

    Directory of Open Access Journals (Sweden)

    Roberto Farné

    2016-10-01

    Full Text Available The success of phenomenology in contemporary culture is due above all to the new approach to knowledge that has been proposed, breaking with the traditional objectivism of scientific knowledge and placing the “phenomenon” at the centre of the relationship between the subject and the world. Everyday reality, the language of concrete things, have become fully-fledged targets of philosophical thought. While Eugen Fink, student of Husserl, elects the phenomenon of play as the “symbol of the world”, the original interpretation of man’s relation to the world, in Italy Piero Bertolini redefines the scientific basis of pedagogy according to phenomenological categories and places play among the fundamental fields of experience of education. On one hand overcoming the traditional educational instrumentalisation of play, on the other its sterile reduction to a consumer experience, Bertolini brings play back to its authentic dimension in which risk, error, adventure are constituent parts, the “active ingredients” of his pedagogy.

  1. Phenomenology between Pathos and Response

    Directory of Open Access Journals (Sweden)

    Bernhard Waldenfels

    2011-03-01

    Full Text Available The author calls phenomenological intentionality, into question while taking it, nevertheless, as a starting point. From the analysis of the meaning of phenomena he goes back to a pathic dimension which precedes them. What happens to us or affects us and to what we respond in different ways cannot be reduced to previous horizons. Between pathos and response, there is an irreducible cleft which constitutes a special sort of time-lag. What happens to us comes is always too early; our responses always come too late. Our experience is never completely up to date. In order to explore this pre-semantic and pre-pragmatic depth of experience we need a sort of responsive reduction, which guides all meaning toward something we respond to. In conclusion, the author evokes some areas in which such a revision of phenomenology shows its effects, namely the genesis of life in bioethics, the historical elaboration of memory and the experience of the Other.

    2011-05-01

    Many models for the acoustical properties of rigid-porous media require knowledge of parameter values that are not available for outdoor ground surfaces. The relationship used between tortuosity and porosity for stacked spheres results in five characteristic impedance models that require not more than two adjustable parameters. These models and hard-backed-layer versions are considered further through numerical fitting of 42 short range level difference spectra measured over various ground surfaces. For all but eight sites, slit-pore, phenomenological and variable porosity models yield lower fitting errors than those given by the widely used one-parameter semi-empirical model. Data for 12 of 26 grassland sites and for three beech wood sites are fitted better by hard-backed-layer models. Parameter values obtained by fitting slit-pore and phenomenological models to data for relatively low flow resistivity grounds, such as forest floors, porous asphalt, and gravel, are consistent with values that have been obtained non-acoustically. Three impedance models yield reasonable fits to a narrow band excess attenuation spectrum measured at short range over railway ballast but, if extended reaction is taken into account, the hard-backed-layer version of the slit-pore model gives the most reasonable parameter values.

  3. Is there nursing phenomenology after Paley? Essay on rigorous reading.

    Science.gov (United States)

    2014-01-01

    At the bedside, nurses are expected to be precise when they read indications on screens and on the bodies of patients and decide on the meaning of words framed by the context of acute care. In academia, although there is no incident report to fill when we misread or misrepresent complex philosophical ideas, the consequences of inaccurate reading include misplaced epistemological claims and poor scholarship. A long and broad convention of nursing phenomenological research, in its various forms, claims a philosophical grounding in the ideas of Husserl, Heidegger, and other thinkers. But for nearly two decades, nurse phenomenologists' knowledge claims have been challenged by well-informed criticisms, most notably by John Paley. At the heart of criticism lies an observation that Continental phenomenological thought is misrepresented in many nursing sources and that nursing phenomenology, both descriptive and interpretive, cannot appeal to the authority of either Husserl or Heidegger. Taking these criticisms seriously, I am asking, Is phenomenology after Paley possible? If misreading seems to be an issue, how can - or should - we read rigorously? My thinking through these questions is influenced by the ideas of Jacques Derrida. Under a condition of a play of language, of Derridian différance, when meaning is never self-identical and never fully arrives, I suggest that one has to negotiate meanings through reading for differences. I develop this idea in relation to the methodological conventions of phenomenological nursing research and argue for a careful rereading of the whole field of phenomenological nursing research. Such rereading presupposes and necessitates interdisciplinary engagement between nursing and the humanities and interpretive social sciences. Greater familiarity with research practices of those disciplines that stress theoretical and writing rigour might make visible the limits of nursing research approaches and their quality criteria.

  4. A corrugated termination shock in pulsar wind nebulae?

    CERN Document Server

    Lemoine, M

    2016-01-01

    Successful phenomenological models of pulsar wind nebulae assume efficient dissipation of the Poynting flux of the magnetized electron-positron wind as well as efficient acceleration of the pairs in the vicinity of the termination shock, but how this is realized is not yet well understood. The present paper suggests that the corrugation of the termination shock, at the onset of non-linearity, may lead towards the desired phenomenology. Non-linear corrugation of the termination shock would convert a fraction of order unity of the incoming ordered magnetic field into downstream turbulence, slowing down the flow to sub-relativistic velocities. The dissipation of turbulence would further preheat the pair population on short length scales, close to equipartition with the magnetic field, thereby reducing the initial high magnetization to values of order unity. Furthermore, it is speculated that the turbulence generated by the corrugation pattern may sustain a relativistic Fermi process, accelerating particles close...

    2006-04-01

    Phenomenology has been divided into three schools of thought arising from different philosophical assumptions and methods. There is descriptive phenomenology, interpretative phenomenology, and a combination of both. Phenomenology has been adopted as a study method to explore experiences in different nursing fields in Taiwan. Husserlian descriptive phenomenology professes to utilize the skills of epoché, bracketing, and phenomenological reduction not only in order to seek the essence of phenomena, but also to allow the researcher to get into the participant's life-world to gain a deeper understanding of their experience; in other words, to let the true phenomenon or essence be revealed. By contrast, Heideggerian interpretative phenomenology rejected the idea that one can completely suspend one's presuppositions, prejudices or preconceived ideas by simply Being-in-the-world. One is immersed in and absorbing from the world, so one will not be able to notice everything that one is gaining from the world. Heidegger also insisted that any interpretation is only valid when background is taken into account. This not only facilitates the researcher's deeper understanding of the other's experience, but also facilitates more accurate interpretation of context and meaning. When researchers seek to follow Husserl's idea of performing bracketing in descriptive phenomenology, in order to truly put the concept into practice, they should understand their prior assumptions and maintain a written journal of reflections throughout the study.

    2000-12-01

    This essay is concerned with the question which philosophical traditions underpin the phenomenological perspective in nursing research. The word phenomenology is often used synonymously on the level of the theory of science as well as on the level of research methods. Besides the similarity in the designation of phenomenology as a philosophical tradition and as a research method, there are to be found a number of terms in the nursing literature, such as hermeneutic, interpretive or interpretative phenomenology. Therefore it is hard to differentiate between the various accounts and to use them for a concrete inquiry in nursing. The differences and the resulting consequences for phenomenological research methods shall be described whereby the ideas of Edmund Husserl and Martin Heidegger are taken into account.

  16. The phenomenology of trapped inflation

    CERN Document Server

    Pearce, Lauren; Sorbo, Lorenzo

    2016-01-01

    Trapped inflation is a mechanism in which particle production from the moving inflaton is the main source of friction in the inflaton equation of motion. The produced fields source inflaton perturbations, which dominate over the vacuum ones. We employ the set of equations for the inflaton zero mode and its perturbations which was developed in the original work on trapped inflation, and which we extend to second order in the perturbations. We build on this study by updating the experimental constraints, and by replacing the existing approximate solutions with more accurate ones. We obtain a different numerical value for the amplitude of the scalar power spectrum, and a parametrically different result for the bispectrum. This has implications for the allowed region of parameter space in models of trapped inflation, and for some of the phenomenological results obtained in this region. The main results in the allowed region are the following: monomial inflaton potentials, such as $V \\propto \\varphi,\\, \\varphi^2$ ...

    In this thesis we investigate several topics in neutrino physics, with an em- phasis on the phenomenology of the sterile neutrinos. We study the existence of a light sterile neutrino within the so called 3+1 scenario using the data of the medium baseline reactor experiments. We will also probe the parameters of the Large Extra Dimension model with the high energy atmospheric data of the IceCube experiment, and will find an equivalence between the Kaluza Klein modes and the sterile neutrinos. We will study the secret interaction of the ster- ile neutrinos which is proposed to solve the tension between cosmology and the sterile neutrino hypothesis. In addition to these, we will show that a minimal 2-Higgs-Doublet-Model extended with a U(1) or Z_2 symmetry cannot explain the smallness of the neutrino masses.

  18. Phenomenology of magnetospheric radio emissions

    Jupiter has now been observed over 24 octaves of the radio spectrum, from about 0.01 MHz to 300,000 MHz. Its radio emissions fill the entire spectral region where interplanetary electromagnetic propagation is possible at wavelengths longer than infrared. Three distinct types of radiation are responsible for this radio spectrum. Thermal emission from the atmosphere accounts for virtually all the radiation at the high frequency end. Synchrotron emission from the trapped high-energy particle belt deep within the inner magnetosphere is the dominant spectral component from about 4000 to 40 MHz. The third class of radiation consists of several distinct components of sporadic low frequency emission below 40 MHz. The decimeter wavelength emission is considered, taking into account the discovery of synchrotron emission, radiation by high-energy electrons in a magnetic field, and the present status of Jovian synchrotron phenomenology. Attention is also given to the decameter and hectometer wavelength emission, and emissions at kilometric wavelengths.

    2015-01-01

    Metasurfaces, with their superior capability in manipulating the optical wavefront at the subwavelength scale and low manufacturing complexity, have shown great potential for planar photonics and novel optical devices. However, vector field simulation of metasurfaces is so far limited to periodic-structured metasurfaces containing a small number of meta-atoms in the unit cell by using full-wave numerical methods. Here, we propose a general phenomenological method to analytically model metasurfaces made up of arbitrarily distributed meta-atoms based on the assumption that the meta-atoms possess localized resonances with Lorentz-Drude forms, whose exact form can be retrieved from the full wave simulation of a single element. Applied to phase modulated geometric metasurfaces, our analytical results show good agreement with full-wave numerical simulations. The proposed theory provides an efficient method to model and design optical devices based on metasurfaces.

  20. Observation and phenomenology of glueballs

    Lindenbaum, S.J.

    1985-01-01

    The experimental evidence and the relevant phenomenology of glueballs are reviewed. The opinion is expressed that the glueball resonance explanation is the only viable one for the data on g/sub T/, g/sub T/sup 1//, and g/sub T/sup 11//. It is shown that alternative explanations are either incorrect, or do not fit the data, or both, leading to the conclusion that these states are probably produced by glueballs. The OZI rule is explained. Glueball masses and width are considered. Some conclusions are drawn regarding an OZI suppressed reaction ..pi../sup -/p ..-->.. phi phi n. Glueball candidates from the J/psi radiative decay are discussed. 44 refs., 16 figs. (LEW)

  1. Extended class of phenomenological universalities

    2017-08-01

    The phenomenological universalities (PU) are extended to include quantum oscillatory phenomena, coherence and supersymmetry. It will be proved that this approach generates minimum uncertainty coherent states of time-dependent oscillators, which in the dissociation (classical) limit reduce to the functions describing growth (regression) of the systems evolving over time. The PU formalism can be applied also to construct the coherent states of space-dependent oscillators, which in the dissociation limit produce cumulative distribution functions widely used in probability theory and statistics. A combination of the PU and supersymmetry provides a convenient tool for generating analytical solutions of the Fokker-Planck equation with the drift term related to the different forms of potential energy function. The results obtained reveal existence of a new class of macroscopic quantum (or quasi-quantum) phenomena, which may play a vital role in coherent formation of the specific growth patterns in complex systems.

    Sigl, Günter

    2017-01-01

    This books aims at giving an overview over theoretical and phenomenological aspects of particle astrophysics and particle cosmology. To be of interest for both students and researchers in neighboring fields of physics, it keeps a balance between well established foundations that will not significantly change in the future and a more in-depth treatment of selected subfields in which significant new developments have been taking place recently. These include high energy particle astrophysics, such as cosmic high energy neutrinos, the interplay between detection techniques of dark matter in the laboratory and in high energy cosmic radiation, axion-like particles, and relics of the early Universe such as primordial magnetic fields and gravitational waves. It also contains exercises and thus will be suitable for both introductory and advanced courses in astroparticle physics.

A unique feature of the ISSW is the emphasis on bridging the gap between physicists and engineers working in fields as different as gas dynamics, fluid mechanics and materials sciences. The main results presented at these meetings constitute valuable proceedings that offer anyone working in this field an authoritative and comprehensive source of reference.

  5. Birth of a science centre. Italian phenomenology

    2006-06-01

    Full Text Available In May 2004 the Balì Museum, Planetarium and interactive science museum, was opened to the public in Italy: 35 hands-on exhibits designed according to the interactive tradition of the Exploratorium in San Francisco, an astronomic observatory for educational activities, a Planetarium with 70 places. With a total investment of about three million euros, about two thirds of which were spent on restructuring the splendid eighteenth-century villa in which it is housed, the undertaking may be considered a small one in comparison with other European science centres. Three million euros: perhaps enough to cover the cost of only the splendid circular access ramp to the brand-new Cosmocaixa in Barcelona, an investment of one hundred million euros. But the interesting aspect of the story of the Balì Museum (but also of other Italian stories, as we shall see lies in the fact that this lively and advanced science centre stands in the bucolic region of the Marches, next to a small town of only 800 inhabitants (Saltara, in the Province of Pesaro and Urbino, in a municipal territory that has a total of 5000. Whereas in Italy the projects for science centres comparable with the Catalan one, for example projects for Rome and Turin, never get off the ground, smaller ones are opening in small and medium-sized towns: why is this? And what does the unusual location of the centres entail for science communication in Italy? This Focus does not claim to tell the whole truth about Italian interactive museums, but it does offer some phenomenological cues to open a debate on the cultural, economic and political premises that favour their lives.

    Definitions of shock types. Hypovolaemic shock is a state of insufficient perfusion of vital organs with consecutive imbalance of oxygen supply and demand due to an intravascular volume deficiency with critically impaired cardiac preload. Subtypes are haemorrhagic shock, hypovolaemic shock in the narrow sense, traumatic-haemorrhagic shock and traumatic-hypovolaemic shock. Cardiac shock is caused by a primary critical cardiac pump failure with consecutive inadequate oxygen supply of the organism. Anaphylactic shock is an acute failure of blood volume distribution (distributive shock) and caused by IgE-dependent, type-I-allergic, classical hypersensibility, or a physically, chemically, or osmotically induced IgE-independent anaphylactoid hypersensibility. The septic shock is a sepsis-induced distribution failure of the circulating blood volume in the sense of a distributive shock. The neurogenic shock is a distributive shock induced by generalized and extensive vasodilatation with consecutive hypovolaemia due to an imbalance of sympathetic and parasympathetic regulation of vascular smooth muscles.

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

    We study products of precursors of spatially local operators, $W_{x_{n}}(t_{n}) ... W_{x_1}(t_1)$, where $W_x(t) = e^{-iHt} W_x e^{iHt}$. Using chaotic spin-chain numerics and gauge/gravity duality, we show that a single precursor fills a spatial region that grows linearly in $t$. In a lattice system, products of such operators can be represented using tensor networks. In gauge/gravity duality, they are related to Einstein-Rosen bridges supported by localized shock waves. We find a geometrical correspondence between these two descriptions, generalizing earlier work in the spatially homogeneous case.

    2016-04-01

    Full Text Available In this survey, it is aimed to determine parents’ thoughts of children using a toys library opened within a public library. The concept of a “Toys Library”, which is growing in popularity, combines the perceptions of toys and library, based on the principle of lending toys out to disadvantaged children. This study is a qualitative phenomenological research in which parents’ thoughts and knowledge gathered from the literature are examined. The study group is composed of 306 children, 134 from pre-schools and 172 from primary schools, and their parents. In this research, which is based on proper sampling method, statistical data were obtained from the software prepared for the toys library and qualitative data obtained from semi-structured interviews over a 12 month period. As a result of content analysis of 48 parents interviews recorded via video, it has been concluded that the project contributed to the functioning of the public libraries, has fully met the children’s toys needs, and has positively affected the children’s character and social development. As a result of this project, it is hoped that the survey will be seen as a reference point for toy libraries planned to be opened elsewhere.

    Among three typical energy scales, a neutrino mass scale (m{sub {nu}}{approx}0.1eV), a GUT scale (M{sub GUT}{approx}10{sup 16}GeV), and a TeV-scale (M{sub NP}{approx}1TeV), there is a fascinating relation of M{sub NP} Asymptotically-Equal-To {radical}(m{sub {nu}} Dot-Operator M{sub GUT}) The TeV-scale, M{sub NP}, is a new physics scale beyond the standard model which is regarded as 'supersymmetry' (SUSY) in this letter. We investigate phenomenology of SUSY SU(5) GUT with neutrinophilic Higgs, which realizes the above relation dynamically as well as the suitable magnitude of Dirac mass, m{sub {nu}}, through a tiny vacuum expectation value of neutrinophilic Higgs. As a remarkable feature of this model, accurate gauge coupling unification can be achieved as keeping with a proton stability. We also evaluate flavor changing processes in quark/lepton sectors.

    Full Text Available Starting with an overview of possible solutions to the problem of social order, the author presents a non-acritical reconstruction of Edmund Husserl's transcendental phenomenology of intersubjectivity as a sympathetic alternative to Habermas's theory of communicative action. By means of a detailed analysis of the concept of empathy (Einfühlung, he shows that Husserl's phenomenology of intersubjectivity offers a triple foundation of the sciences. As a warrant of the objectivity of the world, it grounds the natural sciences; as a presupposition of sociality, it founds the social sciences; as mediated by culture, it grounds the social sciences as human sciences.

    2010-01-01

    An accurate knowledge of the coalescing binary gravitational waveform is crucial for match filtering techniques, which are currently used in the observational searches performed by the LIGO-Virgo collaboration. Following an earlier paper by the same authors we expose the construction of analytical phenomenological waveforms describing the signal sourced by generically spinning binary systems. The gap between the initial inspiral part of the waveform, described by spin-Taylor approximants, and its final ring-down part, described by damped exponentials, is bridged by a phenomenological phase calibrated by comparison with the dominant spherical harmonic mode of a set of waveforms including both numerical and phenomenological waveforms of a different type. All waveforms considered describe equal mass systems with dimension-less spin magnitudes equal to 0.6. The noise-weighted overlap integral between numerical and phenomenological waveforms ranges between 0.93 and 0.98 for a wide span of mass values.

    The purpose of this paper is to place side by side the experimental results of Piezonu- clear reactions, which have been recently unveiled, and those collected during the last twenty years of experiments on low energy nuclear reactions (LENR). We will briefy re- port the results of our campaign of piezonuclear reactions experiments where ultrasounds and cavitation were applied to solutions of stable elements. These outcomes will be shown to be compatible with the results and evidences obtained from low energy nuclear reac- tion experiments. Some theoretical concepts and ideas, on which our experiments are grounded, will be sketched and it will be shown that, in order to trigger our measured effects, it exists an energy threshold, that has to be overcome, and a maximum inter- val of time for this energy to be released to the nuclear system. Eventually, a research hypothesis will be put forward about the chance to raise the level of analogy from the mere comparison of results up to the phenomenological level. H...

  15. Phenomenology and its application in medicine.

    Science.gov (United States)

    Carel, Havi

    2011-02-01

    Phenomenology is a useful methodology for describing and ordering experience. As such, phenomenology can be specifically applied to the first person experience of illness in order to illuminate this experience and enable health care providers to enhance their understanding of it. However, this approach has been underutilized in the philosophy of medicine as well as in medical training and practice. This paper demonstrates the usefulness of phenomenology to clinical medicine. In order to describe the experience of illness, we need a phenomenological approach that gives the body a central role and acknowledges the primacy of perception. I present such a phenomenological method and show how it could usefully illuminate the experience of illness through a set of concepts taken from Merleau-Ponty. His distinction between the biological body and the body as lived, analysis of the habitual body, and the notions of motor intentionality and intentional arc are used to capture the experience of illness. I then discuss the applications this approach could have in medicine. These include narrowing the gap between objective assessments of well-being in illness and subjective experiences which are varied and diverse; developing a more attuned dialogue between physicians and patients based on a thick understanding of illness; developing research methods that are informed by phenomenology and thus go beyond existing qualitative methods; and providing medical staff with a concrete understanding of the impact of illness on the life-world of patients.

  16. Understanding the creative processes of phenomenological research: The life philosophy of Løgstrup

    Directory of Open Access Journals (Sweden)

    Annelise Norlyk

    2011-11-01

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

  17. Schizophrenia: from phenomenology to neurobiology.

    Science.gov (United States)

    Wong, Albert Hung Choy; Van Tol, Hubert H M

    2003-05-01

    Schizophrenia is a common and debilitating illness, characterized by chronic psychotic symptoms and psychosocial impairment that exact considerable human and economic costs. The literature in electronic databases as well as citations and major articles are reviewed with respect to the phenomenology, pathology, treatment, genetics and neurobiology of schizophrenia. Although studied extensively from a clinical, psychological, biological and genetic perspective, our expanding knowledge of schizophrenia provides only an incomplete understanding of this complex disorder. Recent advances in neuroscience have allowed the confirmation or refutation of earlier findings in schizophrenia, and permit useful comparisons between the different levels of organization from which the illness has been studied. Schizophrenia is defined as a clinical syndrome that may include a collection of diseases that share a common presentation. Genetic factors are the most important in the etiology of the disease, with unknown environmental factors potentially modulating the expression of symptoms. Schizophrenia is a complex genetic disorder in which many genes may be implicated, with the possibility of gene-gene interactions and a diversity of genetic causes in different families or populations. A neurodevelopmental rather than degenerative process has received more empirical support as a general explanation of the pathophysiology, although simple dichotomies are not particularly helpful in such a complicated disease. Structural brain changes are present in vivo and post-mortem, with both histopathological and imaging studies in overall agreement that the temporal and frontal lobes of the cerebral cortex are the most affected. Functional imaging, neuropsychological testing and clinical observation are also generally consistent in demonstrating deficits in cognitive ability that correlate with abnormalities in the areas of the brain with structural abnormalities. The dopamine and other

  18. Phenomenology and neurophysiological correlations: two approaches to perception research.

    Science.gov (United States)

    Spillmann, Lothar

    2009-06-01

    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.

  19. Phenomenology of Sarks and Dileptons

    Science.gov (United States)

    Chaudhry, Jyoti

    We have studied three extensions of the standard model; the sark model, the vector quark model and the 331 model. The sark model has a gauge group SU(2) _{X}otimes SU(3)_{C} otimes SU(2)_{S}otimes U(1) _{Q}, where all gauge symmetries are unbroken. The vector-quark model contains an extra vector-like quark doublet. Finally, the 331 model has a gauge group SU(3)_{C}otimes SU(3)_{L}otimes U(1)_{X } where SU(3)otimes U(1)_ {X} contains the standard electroweak group SU(2)_{L}otimes U(1) _{Y}. This model contains three extended fermion families with the third family treated differently and additional vector gauge bosons. In the sark model, the number of quark-lepton families is constrained to three by the asymptotic freedom for the SU(2)_{X} group. Further, quantization of the electric charge is achieved by the anomaly cancellation conditions. Neutral sark baryons, called narks, are candidates for the cosmological dark matter having the characteristics designed for WIMPS. Further phenomenological implications of sarks are analyzed including electron-positron annihilation, Z^{0 } decay, flavor-changing neutral currents, baryon-number non-conservation, sarkonium and the neutron electric dipole moment. Next, we have studied the CP violation parameter Re(epsilon^'/epsilon) in the vector-quark model and also in the 331 model. For a given value of m_{t}, the vector quark model tends to reduce Re(epsilon ^'/epsilon) whereas the 331 model tends to increase it. If m_{t } is discovered around 150 GeV and the lower experimental value for Re(epsilon^ '/epsilon) (0.74+/- 0.60times 10^{-3}, Fermilab) is confirmed, the standard model is acceptable. But, if its higher value (2.3+/- 0.65times 10 ^{-3}, CERN) persists, a dynamics like the 331 model seems to be favored. Lastly, we have looked for the signatures of the dileptons in e^-p and e ^-e^+ colliders. At HERA, with the center-of-mass energy 314 GeV, a dilepton mass above 150 GeV is inaccessible but at LEPII-LHC, with a 1790 Ge

However, these elements do not seem to be carefully examined and are indistinctly understood as objective empirical factors that may be measured, which may contribute to misunderstandings about CR, erroneous interpretations of results and problematic theoretical models.Conclusion: Empirical studies fail when evaluating phenomenological aspects of the cognitive elements of the CR construct. Psychopathology and phenomenology may help define the characteristics of CR elements and may contribute to their understanding and hierarchical organization as a construct. A review of the psychopathology principles established by Jasper may clarify some of these issues.

  2. The current dialogue between phenomenology and psychiatry: a problematic misunderstanding.

    2015-11-01

    A revival of the dialogue between phenomenology and psychiatry currently takes place in the best international journals of psychiatry. In this article, we analyse this revival and the role given to phenomenology in this context. Although this dialogue seems at first sight interesting, we show that it is problematic. It leads indeed to use phenomenology in a special way, transforming it into a discipline dealing with empirical facts, so that what is called "phenomenology" has finally nothing to do with phenomenology. This so-called phenomenology tallies however with what we have always called semiology. We try to explain the reasons why phenomenology is misused in that way. In our view, this transformation of phenomenology into an empirical and objectifying discipline is explained by the role attributed to phenomenology by contemporary authors, which is to solve the problems raised by the Diagnostic and Statistical Manual of Mental Disorders.

    2016-01-01

    In this review, we present an up-to-date phenomenological summary of research developments in physics of the Quark-Gluon Plasma (QGP). A short historical perspective and theoretical motivation for this rapidly developing field of contemporary Particle Physics is provided. In addition, we introduce and discuss the role of the QCD ground state, non-perturbative and lattice QCD results on the QGP properties as well as the transport models used to make a connection between theory and experiment. The experimental part presents the selected results on bulk observables, hard and penetrating probes obtained in the ultra-relativistic heavy-ion experiments carried out at BNL RHIC, CERN SPS and LHC accelerators. We also give a brief overview of new developments related to the ongoing searches of the QCD critical point and to the collectivity in small ($p+p$ and $p+A$) systems.

  7. Heidegger’s phenomenology of the invisible

    Directory of Open Access Journals (Sweden)

    Andrzej SERAFIN

    2016-12-01

    Full Text Available Martin Heidegger has retrospectively characterized his philosophy as “phenomenology of the invisible”. This paradoxical formula suggests that the aim of his thinking was to examine the origin of the phenomena. Furthermore, Heidegger has also stated that his philosophy is ultimately motivated by a theological interest, namely the question of God’s absence. Following the guiding thread of those remarks, this essay analyzes the essential traits of Heidegger’s thought by interpreting them as an attempt to develop a phenomenology of the invisible. Heidegger’s attitude towards physics and metaphysics, his theory of truth, his reading of Aristotle, his concept of Dasein, his understanding of nothingness are all situated within the problematic context of the relation between the invisible and the revealed. Heidegger’s thought is thereby posited at the point of intersection of phenomenology, ontology, and theology.

  8. The Nonlinear World Conceptual Analysis and Phenomenology

    CERN Document Server

    Oono, Yoshitsugu

    2013-01-01

    The most important characteristic of the “world filled with nonlinearity” is the existence of scale interference: disparate space–time scales interfere with each other. Thus, the effects of unknowable scales invade the world that we can observe directly. This leads to various peculiar phenomena such as chaos, critical phenomena, and complex biological phenomena, among others. Conceptual analysis and phenomenology are the keys to describe and understand phenomena that are subject to scale interference, because precise description of unfamiliar phenomena requires precise concepts and their phenomenological description. The book starts with an illustration of conceptual analysis in terms of chaos and randomness, and goes on to explain renormalization group philosophy as an approach to phenomenology. Then, abduction is outlined as a way to express what we have understood about the world. The book concludes with discussions on how we can approach genuinely complex phenomena, including biological phenomena. T...

  9. The essence of sporting embodiment: phenomenological analyses of the sporting body

    OpenAIRE

    2009-01-01

    Whilst in recent years the sociology of sport has taken to heart vociferous calls ‘to bring the body back in’ to analyses of sporting activity, the ‘promise of phenomenology’ signalled by Kerry and Armour (2000), remains under-realised with regard to sporting embodiment. Surprisingly, given the focus of study, relatively few accounts are truly grounded in the corporeal realities of the lived, sensuous sporting body. Phenomenology offers us a powerful framework for such analysis and has been a...

  10. An inverse model for magnetorheological dampers based on a restructured phenomenological model

    Science.gov (United States)

    Qian, Li-Jun; Liu, Bo; Chen, Peng; Bai, Xian-Xu

    2016-04-01

    Magnetorheological dampers (MRDs), a semi-active actuator based on MR effect, have great potential in vibration/shock control systems. However, it is difficult to establish its inverse model due to its intrinsic strong nonlinear hysteresis behaviors, and sequentially the precise, fast and effective control could not be realized effectively. This paper presents an inverse model for MRDs based on a restructured phenomenological model with incorporation of the "normalization" concept. The proposed inverse model of MRDs is validated by the simulation of the force tracking. The research results indicate that the inverse model could be applied for the damping force control with consideration of the strong nonlinear hysteresis behaviors of the MRDs.

  11. Geometrical shock dynamics for magnetohydrodynamic fast shocks

    KAUST Repository

    Mostert, W.

    2016-12-12

    We describe a formulation of two-dimensional geometrical shock dynamics (GSD) suitable for ideal magnetohydrodynamic (MHD) fast shocks under magnetic fields of general strength and orientation. The resulting area–Mach-number–shock-angle relation is then incorporated into a numerical method using pseudospectral differentiation. The MHD-GSD model is verified by comparison with results from nonlinear finite-volume solution of the complete ideal MHD equations applied to a shock implosion flow in the presence of an oblique and spatially varying magnetic field ahead of the shock. Results from application of the MHD-GSD equations to the stability of fast MHD shocks in two dimensions are presented. It is shown that the time to formation of triple points for both perturbed MHD and gas-dynamic shocks increases as (Formula presented.), where (Formula presented.) is a measure of the initial Mach-number perturbation. Symmetry breaking in the MHD case is demonstrated. In cylindrical converging geometry, in the presence of an azimuthal field produced by a line current, the MHD shock behaves in the mean as in Pullin et al. (Phys. Fluids, vol. 26, 2014, 097103), but suffers a greater relative pressure fluctuation along the shock than the gas-dynamic shock. © 2016 Cambridge University Press

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

    Science.gov (United States)

    Earle, Vicki

    2010-10-01

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

    We consider scenarios in the next-to-minimal supersymmetric model (NMSSM) where the CP-odd and charged Higgs bosons are very light. As we demonstrate, these can be obtained as simple deformations of existing phenomenological MSSM benchmarks scenarios with parameters defined at the weak scale. This offers a direct and meaningful comparison to the MSSM case. Applying a wide set of up-to-date constraints from both high-energy collider and flavour physics, the Higgs boson masses and couplings are studied in viable parts of parameter space. The LHC phenomenology of the light Higgs scenario for neutral and charged Higgs boson searches is discussed. (orig.)

  14. Statistical turbulence theory and turbulence phenomenology

    Science.gov (United States)

    Herring, J. R.

    1973-01-01

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

    Using a global Bayesian analysis, it is shown how the results from 7 and 8 $\\textrm{TeV}$ searches for supersymmetry performed by the CMS experiment constrain the Minimal Supersymmetric StandardModel (MSSM). The study is performed within the framework of the phenomenologicalMSSM (pMSSM), a 19-parameter realization of the R-parity conserving weak scale MSSM, that captures most of the latter's phenomenological features and which,therefore, permits robust conclusions to be drawn about the MSSM.

    2008-01-01

    What does it mean to have cancer as a child or adolescent? To understand this, researchers must study the illness from the child's point of view and listen to these children's descriptions of their "lived world." Phenomenology is a qualitative research methodology that can be used to discover and interpret meaning. To use phenomenology congruently, the philosophical background must be understood as well as the adaptation of the philosophical basis to research in the caring sciences. Only when clinicians truly understand the meaning of this illness to the child can they design nursing interventions to ease suffering and increase quality of life in children and adolescents with cancer.

  18. [An existential-phenomenological approach to consciousness].

    Science.gov (United States)

    Langle, A

    2014-01-01

    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.

    2013-11-01

    Full Text Available It is my intention to elucidate what are the foundations of the truth of those propositions that express what the phenomenological tradition since Husserl has called a «material a priori». My aim is not to paraphrase Husserl, but to try to specify the evidence we have of such claims. I aim to consider to what extent at the basis of such an evidence lays linguistic meaning and how the traditional phenomenological understanding of that evidence may be improved resorting to ideas that are close in spirit to the latter Wittgenstein.

  20. Speak Simply When Warning About After Shocks

    Science.gov (United States)

    Michael, A. J.; Hardebeck, J.; Page, M. T.; van der Elst, N.; Wein, A. M.

    2016-12-01

    When a fault in the ground slips, the ground moves fast and can shake hard. After a big ground shake, there are more shakes. We call them after shocks and these can happen over a long time, for many years. An after shock can shake the ground more than it shook the first time. These shocks can shake and break places where people live and work, make rocks fall down and the ground go soft and wet, and hurt or kill people. After shocks also make people worry. If people are scared, then they may leave the area and not come back. To help people be safe and feel calm we want to tell them what may happen. We often use big words and lots of numbers to give the chances for the number of shakes over days, weeks, and years. That helps some people fix things and do their jobs such as those who work on roads, power, water, phones, hospitals, schools or in the money business. But big words and too many numbers can confuse a lot of people and make them worry more. Studies of talking about the ground shake problem show that it is best to speak simply to people. What if we only use the ten hundred most often used words to talk about these ground shakes. Would that work? Here is a possible warning: Last week's huge ground shake will probably make more ground shakes. This week expect to feel three to ten ground shakes and maybe one big ground shake that could break things. That big ground shake has a chance of 1 in 10. This is normal. Be safe. Stay out of broken houses, shops, and work places. When you feel the ground shake: drop, cover, and hold on. People may feel afraid or be hurt, so check on friends and family. Get some more food and water. Over time there will be fewer ground shakes, but always be ready for them. That warning gives a lot of key ideas: what may happen, whether houses could get broken, that what is happening is normal, and what people may feel and should do. These are the key parts of a good warning. Maybe we should use the most often used words all the time.

  1. Radiative Shock Waves In Emerging Shocks

    Science.gov (United States)

    Drake, R. Paul; Doss, F.; Visco, A.

    2011-05-01

    In laboratory experiments we produce radiative shock waves having dense, thin shells. These shocks are similar to shocks emerging from optically thick environments in astrophysics in that they are strongly radiative with optically thick shocked layers and optically thin or intermediate downstream layers through which radiation readily escapes. Examples include shocks breaking out of a Type II supernova (SN) and the radiative reverse shock during the early phases of the SN remnant produced by a red supergiant star. We produce these shocks by driving a low-Z plasma piston (Be) at > 100 km/s into Xe gas at 1.1 atm. pressure. The shocked Xe collapses to > 20 times its initial density. Measurements of structure by radiography and temperature by several methods confirm that the shock wave is strongly radiative. We observe small-scale perturbations in the post-shock layer, modulating the shock and material interfaces. We describe a variation of the Vishniac instability theory of decelerating shocks and an analysis of associated scaling relations to account for the growth of these perturbations, identify how they scale to astrophysical systems such as SN 1993J, and consider possible future experiments.

  3. The status of Husserlian phenomenology in caring research.

    Science.gov (United States)

    Giorgi, A

    2000-01-01

    In a recent article, Paley criticized nursing research that claimed to be phenomenological and recommended that all reference to Husserl be dropped by nurses following certain qualitative procedures. The purpose of this article is to demonstrate that Paley is wrong in his recommendation by showing that Paley (i) does not distinguish scientific phenomenology from philosophical phenomenology; (ii) is severely limited with respect to scholarly references that legitimate and articulate the scientific phenomenological method; (iii) seems to be unaware of the precedents for attempting scholarly analyses of the experiences and behaviors of others; and (iv) seems to be unaware of the internal history of the development of the scientific phenomenological method, which would show its close relationship to Husserl. Although deficiencies in nursing phenomenological research can be found, the solution is not to drive the researchers away from phenomenology, but to encourage them to apply the scientific phenomenological method in a better way.

  6. High-resolution studies of double-layered ejecta craters: Morphology, inherent structure, and a phenomenological formation model

    Science.gov (United States)

    Wulf, Gerwin; Kenkmann, Thomas

    2015-02-01

    The ejecta blankets of impact craters in volatile-rich environments often possess characteristic layered ejecta morphologies. The so-called double-layered ejecta (DLE) craters are characterized by two ejecta layers with distinct morphologies. The analysis of high-resolution image data, especially HiRISE and CTX, provides new insights into the formation of DLE craters. A new phenomenological excavation and ejecta emplacement model for DLE craters is proposed based on a detailed case study of the Martian crater Steinheim—a well-preserved DLE crater—and studies of other DLE craters. The observations show that the outer ejecta layer is emplaced as medial and distal ejecta that propagate outwards in a debris avalanche or (if saturated with water) a debris flow mode after landing, overrunning previously formed secondary craters. In contrast, the inner ejecta layer is formed by a translational slide of the proximal ejecta deposits during the emplacement stage that overrun and superimpose parts of the outer ejecta layer. Based on our model, DLE craters on Mars are the result of an impact event into a rock/ice mixture that produces large amounts of shock-induced vaporization and melting of ground ice, leading to high ejection angles, proximal landing positions, and an ejecta curtain with relatively wet (in terms of water in liquid form) composition in the distal part versus dryer composition in the proximal part. As a consequence, basal melting of ice components in the ejecta at the transient crater rim, which is induced by frictional heating and the enhanced pressure at depth, initiates an outwards directed collapse of crater rim material in a translational slide mode. Our results indicate that similar processes may also be applicable for other planetary bodies with volatile-rich environments, such as Ganymede, Europa, and the Earth.

  7. Dreaming Consciousness: A Contribution from Phenomenology

    Directory of Open Access Journals (Sweden)

    Nicola Zippel

    2016-08-01

    Full Text Available The central aim of this paper is to offer a historical reconstruction of phenomenological studies on dreaming and to put forward a draft for a phenomenological theory of the dream state. Prominent phenomenologists have offered an extremely valuable interpretation of the dream as an intentional process, stressing its relevance in understanding the complexity of the mental life of subject, the continuous interplay between reality and unreality, and the possibility of building parallel spheres of experience influencing the development of personal identity. Taking into consideration the main characteristics of dream experience emphasized by these scholars, in the final part of the paper I propose to elaborate a new phenomenology of dreaming, which should be able to offer a theoretical description of dream states. My sketched proposal is based on Eugen Fink’s notion of the dream as “presentification”. By combining the past and the present of phenomenological investigation, I aim at suggesting a philosophical framework to explain the intentional features of dreaming as Erlebnis.

  13. Medical phenomenology and stroke rehabilitation: an introduction.

    Science.gov (United States)

    Goldberg, Gary

    2011-01-01

    This issue of Topics in Stroke Rehabilitation explores the theme of medical phenomenology and stroke rehabilitation through open peer commentary format. The theme is introduced by a brief summary and overview of phenomenology as a branch of philosophy whose focus is the development of methodology for describing and ordering human experience. The application of this philosophical approach to medicine in general and stroke rehabilitation in particular is then considered. An approach to patients informed by both phenomenology and science provides a more complete, holistic, and humanistic framework than science alone. Phenomenology helps the clinician to understand the importance of narrative, the process of adaptation at the level of the integrated whole person, and the important role of context in determining how recovery unfolds. Embodiment is presented as an organizing principle that links the nature of conscious experience in the lived body and the basic transformation in experience and function associated with an acquired pathology such as stroke. Finally, the nature of open peer commentary is considered and introduced in terms of how it has been specifically implemented in this issue of Topics in Stroke Rehabilitation.

  18. Why natural science needs phenomenological philosophy.

    Science.gov (United States)

    Rosen, Steven M

    2015-12-01

    Through an exploration of theoretical physics, this paper suggests the need for regrounding natural science in phenomenological philosophy. To begin, the philosophical roots of the prevailing scientific paradigm are traced to the thinking of Plato, Descartes, and Newton. The crisis in modern science is then investigated, tracking developments in physics, science's premier discipline. Einsteinian special relativity is interpreted as a response to the threat of discontinuity implied by the Michelson-Morley experiment, a challenge to classical objectivism that Einstein sought to counteract. We see that Einstein's efforts to banish discontinuity ultimately fall into the "black hole" predicted in his general theory of relativity. The unavoidable discontinuity that haunts Einstein's theory is also central to quantum mechanics. Here too the attempt has been made to manage discontinuity, only to have this strategy thwarted in the end by the intractable problem of quantum gravity. The irrepressible discontinuity manifested in the phenomena of modern physics proves to be linked to a merging of subject and object that flies in the face of Cartesian philosophy. To accommodate these radically non-classical phenomena, a new philosophical foundation is called for: phenomenology. Phenomenological philosophy is elaborated through Merleau-Ponty's concept of depth and is then brought into focus for use in theoretical physics via qualitative work with topology and hypercomplex numbers. In the final part of this paper, a detailed summary is offered of the specific application of topological phenomenology to quantum gravity that was systematically articulated in The Self-Evolving Cosmos (Rosen, 2008a).

  3. Putting phenomenology in its place: some limits of a phenomenology of medicine.

    Science.gov (United States)

    Sholl, Jonathan

    2015-12-01

    Several philosophers have recently argued that phenomenology is well-suited to help understand the concepts of health, disease, and illness. The general claim is that by better analysing how illness appears to or is experienced by ill individuals--incorporating the first-person perspective--some limitations of what is seen as the currently dominant third-person or 'naturalistic' approaches to understand health and disease can be overcome. In this article, after discussing some of the main insights and benefits of the phenomenological approach, I develop three general critiques of it. First, I show that what is often referred to as naturalism tends to be misunderstood and/or misrepresented, resulting in straw-man arguments. Second, the concept of normality is often problematically employed such that some aspects of naturalism are actually presupposed by many phenomenologists of medicine. Third, several of the key phenomenological insights and concepts, e.g. having vs. being a body, the alienation of illness, the epistemic role of the first-person perspective, and the idea of health within illness, each bring with them new problems that limit their utility. While acknowledging the possible contributions of phenomenology, these criticisms point to some severe limitations of bringing phenomenological insights to bear on the problems facing philosophy of medicine that should be addressed if phenomenology is to add anything substantially new to its debates.

We investigate this universal principle through an interdisciplinary study of shock-induced cavitation inside liquid volumes, isolated in 2 and 3 dimensions. By combining high-speed visualizations of ideal water drops realized in microgravity with smoothed particle simulations we evidence strong shock-induced cavitation at the focus of the confined shocks. We extend this analysis to ground-observations of jets and drops using an analytic model, and argue that cavitation caused by trapped shocks offers a distinct mechanism of erosion in high-speed impacts (>100 m/s).

  5. Grounded theory.

    Harris, Tina

    2015-04-29

    Grounded theory is a popular research approach in health care and the social sciences. This article provides a description of grounded theory methodology and its key components, using examples from published studies to demonstrate practical application. It aims to demystify grounded theory for novice nurse researchers, by explaining what it is, when to use it, why they would want to use it and how to use it. It should enable nurse researchers to decide if grounded theory is an appropriate approach for their research, and to determine the quality of any grounded theory research they read.

    2010-01-01

    Introduction. Streptococcal toxic shock syndrome is now recognized as a toxin-mediated, multisystem illness. It is characterized by an early onset of shock with multiorgan failure and continues to be associated with high morbidity and mortality, caused by group A Streptococcus pyogenes. The symptoms for staphylococcal and streptococcal toxic shock syndrome are similar. Streptococcal toxic shock syndrome was not well described until 1993, when children who had suffered from varicella pre...

    Methods and apparatus for treating biomass that may include introducing a biomass to a chamber; exposing the biomass in the chamber to a shock event to produce a shocked biomass; and transferring the shocked biomass from the chamber. In some aspects, the method may include pretreating the biomass with a chemical before introducing the biomass to the chamber and/or after transferring shocked biomass from the chamber.

    Several scientific psychologists consider the approach for the study of perceptive problems of the Experimental Phenomenology is problematic, namely that the phenomenological demonstrations are subjectively based and they do not produce quantifiable results. The aim of this study is to show that Experimental Phenomenology can lead to conclusions objective and quantifiable and propose a procedure allowing to obtain objective measuring using the Rasch mathematical model able to describe the experimental data gathered in Experimental Phenomenology procedures. In order to demonstrate this, a Psychophysics simulated study is proposed. It is possible to carry out a fundamental measurement starting from Experimental Phenomenology by way of the Theory of Conjoint Measurement.

  9. Phenomenology and neurobiology of self disorder in schizophrenia: Primary factors.

    Science.gov (United States)

    Borda, Juan P; Sass, Louis A

    2015-12-01

    Schizophrenia is a heterogeneous syndrome, varying between persons and over course of illness. In this and a companion article, we argue that comprehension of this condition or set of conditions may require combining a phenomenological perspective emphasizing disorders of basic-self experience ("ipseity disturbance") with a multidimensional appreciation of possible neurobiological correlates--both primary and secondary. Previous attempts to link phenomenology and neurobiology generally focus on a single neurocognitive factor. We consider diverse aspects of schizophrenia in light of a diverse, albeit interacting, set of neurocognitive abnormalities, examining both synchronic (structural) interdependence and diachronic (temporal) succession. In this article we focus on the primary or foundational role of early perceptual and motoric disturbances that affect perceptual organization and especially intermodal or multisensory perceptual integration (“perceptual dys-integration”). These disturbances are discussed in terms of their implications for three interconnected aspects of selfhood in schizophrenia, primary forms of: disrupted "hold" or "grip" on the world, hyperreflexivity, diminished self-presence (self-affection). Disturbances of organization or integration imply forms of perceptual incoherence or diminished cognitive coordination. The effect is to disrupt one's ability to apprehend the world in holistic, vital, or contextually grounded fashion, or to fully identify with or experience the unity of one's own body or thinking--thereby generating an early and profound (albeit often subtle) disruption or diminishment of basic or core self and of the sense of existing in a coherent world. We discuss interrelationships or possible complementarities between these three aspects, and consider their relevance for a neurodevelopmental account of schizophrenia.

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

    Science.gov (United States)

    Standal, Øyvind F

    2014-01-01

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

  11. Towards a Non-Supersymmetric String Phenomenology

    CERN Document Server

    Abel, Steven; Mavroudi, Eirini

    2015-01-01

    Over the past three decades, considerable effort has been devoted to studying the rich and diverse phenomenologies of heterotic strings exhibiting spacetime supersymmetry. Unfortunately, during this same period, there has been relatively little work studying the phenomenologies associated with their non-supersymmetric counterparts. The primary reason for this relative lack of attention is the fact that strings without spacetime supersymmetry are generally unstable, exhibiting large one-loop dilaton tadpoles. In this paper, we demonstrate that this hurdle can be overcome in a class of tachyon-free four-dimensional string models realized through coordinate-dependent compactifications. Moreover, as we shall see, it is possible to construct models in this class whose low-lying states resemble the Standard Model (or even potential unified extensions thereof) --- all without any light superpartners, and indeed without supersymmetry at any energy scale. The existence of such models thus opens the door to general stu...

    Ratcliffe, Philip G

    2014-01-01

    This book deals with the development of particle physics, in particular through the exacting and all-important interplay between theory and experiment, an area that has now become known as phenomenology. Particle physics phenomenology provides the connection between the mathematical models created by theoretical physicists and the experimentalists who explore the building blocks of matter and the forces that operate between them. Assuming no more background knowledge than the basics of quantum mechanics, relativistic mechanics and nuclear physics, the author presents a solid and clear motivation for the developments witnessed by the particle physics community at both high and low energies over that last 50 or 60 years. In particular, the role of symmetries and their violation is central to many of the discussions. Including exercises and many references to original experimental and theoretical papers, as well as other useful sources, it will be essential reading for all students and researchers in ...

  13. Facilitating phenomenological interviewing by means of reflexology

    2005-09-01

    Full Text Available The aim of this article is to show how reflexology could facilitate phenomenological interviewing by probing the lifeworld of individual participants. It presents a hybrid study of phenomenological interviewing and reflexology as a holistic method of health care. In this sense, it is an interparadigmatic study, since it rests on the interface of Western and Oriental thought. This article reports on seven cases which were included in the qualitative, empirical investigation. During the sessions, reflexological readings served as impetus for inquiry into the experiences of the participants, as congestions on reflex points and along meridians were interpreted in terms of physical organs and functions. These readings were related to corresponding emotions as accepted within the reflexology paradigm. It was, however, up to the participants to inform the researcher of events and/or circumstances that caused the emotions. Thus, nonverbal data communicated information that facilitated verbal exchange concerning the life-world of each individual participant.

    2016-09-01

    Techniques for improved characterization of Satellites have been an area of research for several years. Many of these approaches show great promise and have been validated using models and simulations. In this paper, multiple phenomenologies that support satellite characterization will be discussed to include: optical, radar, signals, and Infra-Red. The paper will identify satellite characteristics that could be gleaned from the various data types. Algorithms that support extracting the information will be referenced. Unique collection conditions that enable a phenomenology to yield desired data will be discussed. This paper will discuss the impact of changes to satellite characterization data types over the life of an on-orbit asset. The benefits of such information will be discussed, to include re-acquiring objects after a maneuver.

  15. Reenactment interviewing: a methodology for phenomenological research.

    Science.gov (United States)

    Drew, N

    1993-01-01

    Reenactment is proposed as an alternative interviewing strategy for phenomenological research. Three techniques borrowed from the psychodramatic method, warming up, scene-setting and soliloquy, are described as they were used in interviews with nurses participating in a study of caregiver/patient relationships. The rationale for and implementation of the techniques are discussed. Indications of successful reenactment during an interview are described and discussed. The data suggest that skillfully directed reenactment can generate intensely vivid recall of memories experiences and emotions, engendering rich descriptions of participants' lived experience and subsequently, produces significant dialogue between interviewer and participant. Parallels are drawn between phenomenological research/philosophy and the philosophy of action upon which psychodramatic techniques are based.

    CERN Document Server

    Scheck, Florian

    2012-01-01

    Electroweak and Strong Interaction: Phenomenology, Concepts, Models, begins with relativistic quantum mechanics and some quantum field theory which lay the foundation for the rest of the text. The phenomenology and the physics of the fundamental interactions are emphasized through a detailed discussion of the empirical fundamentals of unified theories of strong, electromagnetic, and weak interactions. The principles of local gauge theories are described both in a heuristic and a geometric framework. The minimal standard model of the fundamental interactions is developed in detail and characteristic applications are worked out. Possible signals of physics beyond that model, notably in the physics of neutrinos are also discussed. Among the applications scattering on nucleons and on nuclei provide salient examples. Numerous exercises with solutions make the text suitable for advanced courses or individual study. This completely updated revised new edition contains an enlarged chapter on quantum chromodynamics an...

  18. Phenomenology of Bilinear Broken R-parity

    CERN Document Server

    Restrepo, D A

    2001-01-01

    The straightforward supersymmetrization of the Standard Model (SM) results in a phenomenologically inconsistent theory in which Baryon number ($B$) and Lepton number ($L$) are violated by dimension 4 operators, inducing fast proton decay. Proton stability allows only for separate $L$ or $B$ violation and, if neutrinos are massive Majorana particles, $L$ violating terms must be present. In this thesis I will study a Supersymmetric Standard Model (SSM) realization with $B$ conservation and minimal $L$ violation. In this framework $L$ is mildly violated only by super-renormalizable terms, allowing for small neutrino Majorana masses. This model is more predictive than the Baryon-Parity SSM. The induced dimension 4 $L$ violating couplings are not arbitrary, and automatically satisfy all experimental constraints. After introducing the theoretical framework for supersymmetric models without Lepton number, I will discuss the phenomenology of the (unstable) lightest neutralino and of the lightest stop. I will show tha...

  19. Di-Higgs phenomenology: The forgotten channel

    Englert, Christoph; Spannowsky, Michael; Thompson, Jennifer

    2014-01-01

    Searches for multi-Higgs final states allow to constrain parameters of the SM (or extensions thereof) that directly relate to the mechanism of electroweak symmetry breaking. Multi-Higgs production cross sections, however, are small and the phenomenologically accessible final states are challenging to isolate in the busy multi-jet hadron collider environment of the LHC run 2. This makes the necessity to extend the list of potentially observable production mechanisms obvious. Most of the phenomenological analyses in the past have focused on $gg\\to hh+jets$; in this paper we study $pp\\to t\\bar t hh$ at LHC run 2 and find that this channel for $h\\to b\\bar b$ and semi-leptonic and hadronic top decays has the potential to provide an additional handle to constrain the Higgs trilinear coupling in a global fit at the end of run 2.

    2012-06-01

    We use the recently developed Center for Radiative Shock Hydrodynamics (CRASH) code to numerically simulate laser-driven radiative shock experiments. These shocks are launched by an ablated beryllium disk and are driven down xenon-filled plastic tubes. The simulations are initialized by the two-dimensional version of the Lagrangian Hyades code which is used to evaluate the laser energy deposition during the first 1.1 ns. Later times are calculated with the CRASH code. CRASH solves for the multi-material hydrodynamics with separate electron and ion temperatures on an Eulerian block-adaptive-mesh and includes a multi-group flux-limited radiation diffusion and electron thermal heat conduction. The goal of the present paper is to demonstrate the capability to simulate radiative shocks of essentially three-dimensional experimental configurations, such as circular and elliptical nozzles. We show that the compound shock structure of the primary and wall shock is captured and verify that the shock properties are consistent with order-of-magnitude estimates. The synthetic radiographs produced can be used for comparison with future nozzle experiments at high-energy-density laser facilities.

    In risk studies, engineers often have to consider the consequences of an accident leading to a shock on a construction. This can concern the impact of a ground vehicle or aircraft, or the effects of an explosion on an industrial site.This book presents a didactic approach starting with the theoretical elements of the mechanics of materials and structures, in order to develop their applications in the cases of shocks and impacts. The latter are studied on a local scale at first. They lead to stresses and strains in the form of waves propagating through the material, this movement then extending

    The authors define their concept of psychodiagnostic process as inserted within the doctor-patient relationship general context. Five stages are described (a) administering technique, (b) collecting information, (d) writing report, and (e) retrieving information, and termination. Psychodiagnosis is considered under an epistemological criterion. The report is drawn up according to a phenomenological method. This paper ends up with some reflexions about the concepts of health, disease, doctor-patient relationship, and auxiliary means for diagnosis.

    Highlights of recent phenomenological studies of metal failure are given. Failure leading to spallation and fragmentation are typically of interest. The current ‘best model’ includes the following; a full history stress in tension; nucleation initiating dynamic relaxation; toward a tensile yield function; failure dependent on strain, strain rate, and temperature; a mean-preserving ‘macrodefect’ is introduced when failure occurs in tension; and multifield theoretical refinements

    We investigate the minimal theory of massive gravity (MTMG) recently introduced. After reviewing the original construction based on its Hamiltonian in the vielbein formalism, we reformulate it in terms of its Lagrangian in both the vielbein and the metric formalisms. It then becomes obvious that, unlike previous attempts in the literature of Lorentz-violating massive gravity, not only the potential but also the kinetic structure of the action is modified from the de Rham-Gabadadze-Tolley (dRGT) massive gravity theory. We confirm that the number of physical degrees of freedom in MTMG is two at fully nonlinear level. This proves the absence of various possible pathologies such as superluminality, acausality and strong coupling. Afterwards, we discuss the phenomenology of MTMG in the presence of a dust fluid. We find that on a flat homogeneous and isotropic background we have two branches. One of them (self-accelerating branch) naturally leads to acceleration without the genuine cosmological constant or dark energy. For this branch both the scalar and the vector modes behave exactly as in general relativity (GR). The phenomenology of this branch differs from GR in the tensor modes sector, as the tensor modes acquire a non-zero mass. Hence, MTMG serves as a stable nonlinear completion of the self-accelerating cosmological solution found originally in dRGT theory. The other branch (normal branch) has a dynamics which depends on the time-dependent fiducial metric. For the normal branch, the scalar mode sector, even though as in GR only one scalar mode is present (due to the dust fluid), differs from the one in GR, and, in general, structure formation will follow a different phenomenology. The tensor modes will be massive, whereas the vector modes, for both branches, will have the same phenomenology as in GR.

    Supersymmetry (SUSY) stabilizes the hierarchy between the electroweak scale and the scale of grand unified theories (GUT) or the Planck scale. The simplest supersymmetric extension of the SM, the minimal supersymmetric SM (MSSM) solves several phenomenological problems, e. g. the gauge couplings unify and the lightest supersymmetric particle (LSP) is a dark matter candidate. In this thesis, Jarlskog invariants, squark pair production at the LHC and massive neutrinos are discussed in the framework of the MSSM and its extensions. (orig.)

    We present the second multi-frequency radio detection of a reverse shock in a $\\gamma$-ray burst. By combining our extensive radio observations of the Fermi-LAT GRB 160509A at $z = 1.17$ up to $20$ days after the burst with Swift X-ray observations and ground-based optical and near-infrared data, we show that the afterglow emission comprises distinct reverse shock and forward shock contributions: the reverse shock emission dominates in the radio band at $\\lesssim10~$days, while the forward shock emission dominates in the X-ray, optical, and near-infrared bands. Through multi-wavelength modeling, we determine a circumburst density of $n_0\\approx10^{-3}~$cm$^{-3}$, supporting our previous suggestion that a low-density circumburst environment is conducive to the production of long-lasting reverse shock radiation in the radio band. We infer the presence of a large excess X-ray absorption column, $N_{\\rm H} \\approx 1.5\\times10^{22}~$cm$^{-2}$, and a high rest-frame optical extinction, $A_{\\rm V}\\approx3.4~$mag. We...

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

    Supersonic outflows from objects as varied as stellar jets, massive stars and novae often exhibit multiple shock waves that overlap one another. When the intersection angle between two shock waves exceeds a critical value, the system reconfigures its geometry to create a normal shock known as a Mach stem where the shocks meet. Mach stems are important for interpreting emission-line images of shocked gas because a normal shock produces higher postshock temperatures and therefore a higher-excitation spectrum than an oblique one does. In this paper we summarize the results of a series of numerical simulations and laboratory experiments designed to quantify how Mach stems behave in supersonic plasmas that are the norm in astrophysical flows. The experiments test analytical predictions for critical angles where Mach stems should form, and quantify how Mach stems grow and decay as intersection angles between the incident shock and a surface change. While small Mach stems are destroyed by surface irregularities and ...

    Micro-forming of ultra-thin sheet metals raises numerous challenges. In this investigation, the predictions of state-of-the-art crystal plasticity (CP) and phenomenological models are compared in the framework of industrial bending-dominated forming processes. Sheet copper alloys 0.1mm-thick are considered, with more than 20 grains through the thickness. Consequently, both model approaches are valid on theoretical ground. The phenomenological models’ performance was conditioned by the experimental database used for parameter identification. The CP approach was more robust with respect to parameter identification, while allowing for a less flexible description of kinematic hardening, at the cost of finer mesh and specific grain-meshing strategies. The conditions for accurate springback predictions with CP-based models are investigated, in an attempt to bring these models at the robustness level required for industrial application.

    Full Text Available This paper is a phenomenological critique of some of the basic notions informing much of the researchin and practice of science education (SE today. It is suggested that the philosophical grounds of S Eare in need of three “reversals of primacy”: the ontological primacy of the perceptual lifeworld must replace that of abstract scientific models; the epistemological primacy of attentive practice must replace that of conceptual cognition; and the pedagogical primacy of cultivating competencies must replace that of imparting ready-made knowledge. Four arguments for a phenomenological approach to SE are presented and some consequences for the training of science teachers are discussed; some of which are already being implemented at the science teacher education of the Norwegian University of Life Sciences.

    Grounded cognition rejects traditional views that cognition is computation on amodal symbols in a modular system, independent of the brain's modal systems for perception, action, and introspection. Instead, grounded cognition proposes that modal simulations, bodily states, and situated action underlie cognition. Accumulating behavioral and neural evidence supporting this view is reviewed from research on perception, memory, knowledge, language, thought, social cognition, and development. Theories of grounded cognition are also reviewed, as are origins of the area and common misperceptions of it. Theoretical, empirical, and methodological issues are raised whose future treatment is likely to affect the growth and impact of grounded cognition.

    2012-01-01

    To provide a comprehensive overview of the many research approaches related to phenomenology and their philosophical underpinnings. Phenomenological research approaches are varied and often difficult to apply appropriately. Some researchers persist in labelling their studies as examples of Heideggerian or Husserlian phenomenology without fully understanding the implications of the underpinning philosophical assumptions. Methodological sources related to phenomenology as a philosophy and phenomenology as a research approach are used to illustrate the range of phenomenological methods and their philosophical underpinnings. The origins of phenomenology are the writings of Husserl and the advancement of his thoughts by Merleau-Ponty, Heidegger, Gadamer and Ricoeur. The importance of fully understanding a methodology and its philosophical underpinnings before using it, or claiming to use it, is emphasised. In addition, the variety of phenomenological research approaches that have evolved over the past 50 years are explored and placed in the context of their philosophical underpinnings. There is no single way to conduct a phenomenological study. There are many approaches from which researchers can choose. This has resulted in a range of labels and often in different descriptions for the same approach. It is essential that researchers planning to use phenomenology are familiar with the many approaches available. This knowledge will help researchers choose the approaches that best suit the aims of their studies.

  14. Medicine and the individual: is phenomenology the answer?

    Gergel, Tania L

    2012-10-01

    The issue of how to incorporate the individual's first-hand experience of illness into broader medical understanding is a major question in medical theory and practice. In a philosophical context, phenomenology, with its emphasis on the subject's perception of phenomena as the basis for knowledge and its questioning of naturalism, seems an obvious candidate for addressing these issues. This is a review of current phenomenological approaches to medicine, looking at what has motivated this philosophical approach, the main problems it faces and suggesting how it might become a useful philosophical tool within medicine, with its own individual, but interrelated, contribution to make to current medical debates. After the general background, there is a brief summary of phenomenological ideas and their current usage in a medical context. Next is a critique of four key claims within current phenomenological medical works, concerning both the role phenomenology plays and the supposedly clear divide between phenomenology and other approaches. There are significant problems within these claims, largely because they overlook the complexity of the questions they consider. Finally, there is some more in-depth examination of phenomenology itself and the true complexity of phenomenological debate concerning subjectivity. The aim is to show that it will be both more productive and truer to phenomenology itself, if we use phenomenology as a philosophical method for explicating and gaining deeper understanding of complex and fundamental problems, which are central to medicine, rather than as providing simple, but flawed solutions.

    2008-01-01

    Socrates can, to some extent, be credited with an original conception of what is now seen as 20th century phenomenology 'invented' by Heidegger. With phenomenology becoming more recognised as important in understanding health care and all its complexities, this article by Victoria Vivilaki and Martin Johnson provides a theoretical evaluation of some of the terminology and the underpinning philosophy used in recent phenomenological studies.

    1993-06-01

    Two hundred and seventy patients with schizophrenia (104 patients in Kelantan and 166 patients in Penang) were interviewed using the Present State Examination to elicit the differences in the phenomenology of their hallucinations. The results indicate that there are significant differences in the phenomenology of hallucinations between the Malays of Penang and Kelantan and also among some Chinese patients. These findings indicate that culture does affect the phenomenology of schizophrenia, even among people of the same race but of different regions.

  1. A corrugated termination shock in pulsar wind nebulae?

    Science.gov (United States)

    Lemoine, Martin

    2016-08-01

    Successful phenomenological models of pulsar wind nebulae assume efficient dissipation of the Poynting flux of the magnetized electron-positron wind as well as efficient acceleration of the pairs in the vicinity of the termination shock, but how this is realized is not yet well understood. This paper suggests that the corrugation of the termination shock, at the onset of nonlinearity, may lead towards the desired phenomenology. Nonlinear corrugation of the termination shock would convert a fraction of order unity of the incoming ordered magnetic field into downstream turbulence, slowing down the flow to sub-relativistic velocities. The dissipation of turbulence would further preheat the pair population on short length scales, close to equipartition with the magnetic field, thereby reducing the initial high magnetization to values of order unity. Furthermore, it is speculated that the turbulence generated by the corrugation pattern may sustain a relativistic Fermi process, accelerating particles close to the radiation reaction limit, as observed in the Crab nebula. The required corrugation could be induced by the fast magnetosonic modes of downstream nebular turbulence; but it could also be produced by upstream turbulence, either carried by the wind or seeded in the precursor by the accelerated particles themselves.

  2. Streptococcal toxic shock syndrome

    2010-01-01

    Full Text Available Introduction. Streptococcal toxic shock syndrome is now recognized as a toxin-mediated, multisystem illness. It is characterized by an early onset of shock with multiorgan failure and continues to be associated with high morbidity and mortality, caused by group A Streptococcus pyogenes. The symptoms for staphylococcal and streptococcal toxic shock syndrome are similar. Streptococcal toxic shock syndrome was not well described until 1993, when children who had suffered from varicella presented roughly 2-4 weeks later with a clinical syndrome highly suggestive of toxic shock syndrome. Characteristics, complications and therapy. It is characterized by a sudden onset of fever, chills, vomiting, diarrhea, muscle aches and rash. It can rapidly progress to severe and intractable hypotension and multisystem dysfunction. Almost every organ system can be involved. Complications of streptococcal toxic shock syndrome may include kidney failure, liver failure and even death. Crystalloids and inotropic agents are used to treat the hypovolemic shock aggressively, with close monitoring of the patient’s mean arterial pressure and central venous pressure. An immediate and aggressive management of hypovolemic shock is essential in streptococcal toxic shock syndrome. Targeted antibiotics are indicated; penicillin or a betalactam antibiotic is used for treating group A streptococci, and clindamycin has emerged as a key portion of the standard treatment.

  3. When Shock Waves Collide

    Supersonic outflows from objects as varied as stellar jets, massive stars, and novae often exhibit multiple shock waves that overlap one another. When the intersection angle between two shock waves exceeds a critical value, the system reconfigures its geometry to create a normal shock known as a Mach stem where the shocks meet. Mach stems are important for interpreting emission-line images of shocked gas because a normal shock produces higher postshock temperatures, and therefore a higher-excitation spectrum than does an oblique shock. In this paper, we summarize the results of a series of numerical simulations and laboratory experiments designed to quantify how Mach stems behave in supersonic plasmas that are the norm in astrophysical flows. The experiments test analytical predictions for critical angles where Mach stems should form, and quantify how Mach stems grow and decay as intersection angles between the incident shock and a surface change. While small Mach stems are destroyed by surface irregularities and subcritical angles, larger ones persist in these situations and can regrow if the intersection angle changes to become more favorable. The experimental and numerical results show that although Mach stems occur only over a limited range of intersection angles and size scales, within these ranges they are relatively robust, and hence are a viable explanation for variable bright knots observed in Hubble Space Telescope images at the intersections of some bow shocks in stellar jets.

    Ames Research Center developed a prototype pressure suit for hemophiliac children, based on research of astronauts' physiological responses in microgravity. Zoex Corporation picked up the design and patents and developed an anti-shock garment for paramedic use. Marketed by Dyna Med, the suit reverses the effect of shock on the body's blood distribution by applying counterpressure to the legs and abdomen, returning blood to vital organs and stabilizing body pressure until the patient reaches a hospital. The DMAST (Dyna Med Anti-Shock Trousers) employ lower pressure than other shock garments, and are non-inflatable.

  5. Chiral Shock Waves

    Sen, Srimoyee

    2016-01-01

    We study shock waves in relativistic chiral matter. We argue that the conventional Rankine- Hugoinot relations are modified due to the presence of chiral transport phenomena. We show that the entropy discontinuity in a weak shock wave is linearly proportional to the pressure discontinuity when the effect of chiral transport becomes sufficiently large. We also show that rarefaction shock waves, which do not exist in usual nonchiral fluids, can appear in chiral matter. These features are exemplified by shock propagation in dense neutrino matter in the hydrodynamic regime.

  6. Quantum supergravity, supergravity anomalies and string phenomenology

    2016-01-01

    I discuss the role of quantum effects in the phenomenology of effective supergravity theories from compactification of the weakly coupled heterotic string. An accurate incorporation of these effects requires a regularization procedure that respects local supersymmetry and BRST invariance and that retains information associated with the cut-off scale, which has physical meaning in an effective theory. I briefly outline the Pauli-Villars regularization procedure, describe some applications, and comment on what remains to be done to fully define the effective quantum field theory.

    2011-03-01

    Full Text Available Although manga constitute a massive transcultural flow, they are extremely diverse as far as genre and content are concerned. This article attempts to bridge these differences by highlighting phenomenological patterns within popular manga: by bracketing content, the author focuses on the experience of reading manga, thereby considering the medial aspect of these works. By examining a diverse corpus of contemporary popular series (Bleach, Death Note, Fruits Basket, and Kitchen Princess, the article pays attention to elements such as reading rhythm, contrast, fragmentation, and page tabularity, in order to pave the way for future study of manga’s place in the contemporary medial ethos.

    Finite Unified Theories (FUTs) are N = 1 supersymmetric Grand Unified Theories (GUTs) which can be made finite to all-loop orders, leading to a large reduction in the number of free parameters. We confront the predictions of SU(5) FUTs with the top and bottom quark masses, which allows us to discriminate among different models. We include further low-energy phenomenology constraints, such as B physics observables, the bound on the SM Higgs mass and the cold dark matter density, and then are able to make predictions for the lightest Higgs boson mass and the sparticle spectrum.

  9. Phenomenology of chiral damping in noncentrosymmetric magnets

    KAUST Repository

    Akosa, Collins Ashu

    2016-06-21

    A phenomenology of magnetic chiral damping is proposed in the context of magnetic materials lacking inversion symmetry. We show that the magnetic damping tensor acquires a component linear in magnetization gradient in the form of Lifshitz invariants. We propose different microscopic mechanisms that can produce such a damping in ferromagnetic metals, among which local spin pumping in the presence of an anomalous Hall effect and an effective “s-d” Dzyaloshinskii-Moriya antisymmetric exchange. The implication of this chiral damping in terms of domain-wall motion is investigated in the flow and creep regimes.

  10. Subjectivity and intersubjectivity between semiotics and phenomenology

    Directory of Open Access Journals (Sweden)

    Francesco Marsciani

    2014-12-01

    Full Text Available A semiotic theory of subjectivity cannot prescind from a radical consideration of the intersubjective dimension, which, from the phenomenological perspective, represents the constitutive instance of the meaning of the world. The theory of signification has yet to come to terms with this fundamental option: the theory of enunciation, for example, is still tied to the alternative between an egological perception of the production of meaning and a truly intersubjective conception. A radically intersubjective understanding of the constitution of meaning must, in the theory of enunciation, include an authentic theory of alterity in which the production of communicative intentions can be described based on a more fundamental transcendental intentionality.

    2013-05-01

    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.

    Full Text Available Reconsideration of psychopathology arises from a phenomenological perspective focused on the case of third-generation therapies. Basic principles and bases of the therapeutic actions of functional analytic psychotherapy are described. A way of understanding the psychopathology that encompasses both a transverse diagnosis related to dysfunctional avoidance of psychological events as a theory of pathological formation of Self is presented. Both functional formats of psychopathological explanation would account for multiple clinical diagnoses commonly used. Finally we conclude about the differences and conceptual difficulties between different generations of cognitive-behavioral therapies.

    CERN Document Server

    Olmo, Gonzalo J

    2011-01-01

    We show that a quadratic gravitational Lagrangian in the Palatini formulation is able to capture different aspects of quantum gravity phenomenology in a single framework. In particular, we show that in this theory field excitations propagating with different energy-densities perceive different background metrics, which is a fundamental characteristic of the DSR and Rainbow Gravity approaches. Also, the resulting isotropic and anisotropic cosmologies are free from the big bang singularity. This singularity avoidance occurs non-perturbatively and shares some similitudes with the effective dynamics of loop quantum cosmology.

    2014-01-01

    Global hybrid (electron fluid, kinetic ions) and fully kinetic simulations of the magnetosphere have been used to show surprising interconnection between shocks, turbulence and magnetic reconnection. In particular collisionless shocks with their reflected ions that can get upstream before retransmission can generate previously unforeseen phenomena in the post shocked flows: (i) formation of reconnecting current sheets and magnetic islands with sizes up to tens of ion inertial length. (ii) Generation of large scale low frequency electromagnetic waves that are compressed and amplified as they cross the shock. These 'wavefronts' maintain their integrity for tens of ion cyclotron times but eventually disrupt and dissipate their energy. (iii) Rippling of the shock front, which can in turn lead to formation of fast collimated jets extending to hundreds of ion inertial lengths downstream of the shock. The jets, which have high dynamical pressure, 'stir' the downstream region, creating large scale disturbances such as vortices, sunward flows, and can trigger flux ropes along the magnetopause. This phenomenology closes the loop between shocks, turbulence and magnetic reconnection in ways previously unrealized. These interconnections appear generic for the collisionless plasmas typical of space, and are expected even at planar shocks, although they will also occur at curved shocks as occur at planets or around ejecta.

    Political campaigns today are won or lost in the so-called ground war--the strategic deployment of teams of staffers, volunteers, and paid part-timers who work the phones and canvass block by block, house by house, voter by voter. Ground Wars provides an in-depth ethnographic portrait of two...... infrastructures that utilize large databases with detailed individual-level information for targeting voters, and armies of dedicated volunteers and paid part-timers. Nielsen challenges the notion that political communication in America must be tightly scripted, controlled, and conducted by a select coterie...... of professionals. Yet he also quashes the romantic idea that canvassing is a purer form of grassroots politics. In today's political ground wars, Nielsen demonstrates, even the most ordinary-seeming volunteer knocking at your door is backed up by high-tech targeting technologies and party expertise.

    Full Text Available In this review, we present an up-to-date phenomenological summary of research developments in the physics of the Quark–Gluon Plasma (QGP. A short historical perspective and theoretical motivation for this rapidly developing field of contemporary particle physics is provided. In addition, we introduce and discuss the role of the quantum chromodynamics (QCD ground state, non-perturbative and lattice QCD results on the QGP properties, as well as the transport models used to make a connection between theory and experiment. The experimental part presents the selected results on bulk observables, hard and penetrating probes obtained in the ultra-relativistic heavy-ion experiments carried out at the Brookhaven National Laboratory Relativistic Heavy Ion Collider (BNL RHIC and CERN Super Proton Synchrotron (SPS and Large Hadron Collider (LHC accelerators. We also give a brief overview of new developments related to the ongoing searches of the QCD critical point and to the collectivity in small (p + p and p + A systems.

  2. Phenomenological Model of Charge Localization in the Layered Manganites

    Science.gov (United States)

    Gray, Kenneth E.; Badica, Elvira

    2003-03-01

    The connection of magnetic order with charge delocalization in manganites has received considerable interest recently, and the need to go beyond double exchange (DE) to explain the localized state above TC was first introduced by Millis, et al [Phys. Rev. Lett. 74, 5144 (1995)]. In this spirit, we propose a simple model that can explain the various ground states for layered manganites, La_2-2xSr_1+2xMn_2O_7, in terms of the relative energy gain due to DE compared to a phenomenological localization parameter. This model includes antiferromagnetic (AF) superexchange and thus can also be used for layered manganites exhibiting A-type AF order within the bilayer that we find to be either conducting (x=0.54) or insulating (x=0.48). In a magnetic field, the latter case shows a first order metal-insulator transition that is a signature of a crossover of these energies of the localized and delocalized states. Experimentally, localized states seem to be most strongly favored for x 0.50 although the low-temperature state is not always the CE state and quasi-bi-strip charge order has been observed for x=0.48 by Kubota, et al [J. Phys. Soc. Japan, 69, 1986 (2000)].

  4. The problem of psychopathology and phenomenology. What is viable and not viable in phenomenological psychiatry.

    Science.gov (United States)

    Ramos-Gorostiza, Pablo; Adán-Manes, Jaime

    2013-01-01

    The epistemological underpinnings of psychiatric theory and practice have always been unstable. This reflects the essential contradiction existing between the task (the description and individuation of speech and behavior as psychopathological symptoms) and tools (semiotics). As a result of this contradiction, the history of psychiatry is one of permanent crisis in which there are moments of temporary stability as approaches that aim at organizing this mismatch between tasks and tools gain prevalence. However, these approaches can only offer a false sense of unity, consistency and progress. In this sense, a narrow perspective on a particular period may lead us to believe that psychiatry is just another medical specialty with its own specific theoretical framework like others. However, any such perspective overlooks the coexistence of different schools, disagreements, contradictions, global alternatives, etc. For a certain period of time, phenomenology was assumed to be as the solution for psychiatry’s internal contradiction. As we see it, phenomenology was only partially understood. Despite the great influence it exerted upon psychiatry worldwide, it finally fell into disuse as a mere empiricism. Husserl’s phenomenology was more thoroughly understood and better assimilated by other psychiatrists, and its influence has persisted to the present day. If we view phenomenology in its proper (Husserlian) sense, it is possible to understand psychopathology as a means of creating intelligibility and clarifying the uniqueness of psychiatry. On the other hand, if phenomenology is understood as a representational theory, it will eventually lead to an unavoidable relapse into psychologism, which has been the main path of psychiatry until now.

  5. Fifty years of Yang-Mills Theories: a phenomenological point of view

    2005-01-01

    On the occasion of the celebration of the first half-century of Yang--Mills theories, I am contributing a personal recollection of how the subject, in its early times, confronted physical reality, that is, its "phenomenology". There is nothing original in this work, except, perhaps, my own points of view. But I hope that the older practitioners of the field will find here grounds for nostalgia, or good reasons to disagree with me. Younger addicts may learn that history does not resemble at all what is reflected in current textbooks: it was orders of magnitude more fascinating.

  6. Personality disorders from a phenomenological perspective.

    Science.gov (United States)

    Dörr Zengers, O

    2008-01-01

    Different studies have questioned the capacity of the categorical diagnostics to establish a clear distinction between the existence or not of a determined personality disorder. The dimensional perspective would approach more to reality, in the measure that it tries to measure the different intensity degrees in which these disorders are present in the patients. But its application is very laborious and besides, presupposes that those categories whose nuances it pretends to measure really exist. The foresaid leads us to appeal to phenomenological perspective, which seems to be more adequate for the study of complex realities, as it is the case of the personality and its disorders. The essential features of the phenomenological method in the sense of Husserl are described, as well as his contribution to the study of personality disorders. This can be summarized in three fundamental points: the ideal types, introduced in psychiatry by Karl Jaspers, the existential types, by Ludwig Binswanger, and the dialectic typologies and polarities, by Wolfgang Blankenburg and the undersigned. This author defines and develops each one of these concepts, aiming to show their advantages with respect to the categorical and dimensional systems.

  7. Hermann Weyl's Phenomenological Contribution to Quantum Physics

    Science.gov (United States)

    Mastrobisi, Giorgio J.

    On examining carefully Weyl's writings one realizes that the great mathematician from Göttingen in his researches follows the programmatic scheme of the binomial of "wissenschaftliche Erkenntnis" (scientific Knowledge) and "philosophische Besinnung" (philosophical Reflection). In 1954 in a retrospective writing he affirmed: «The formulation of Einstein's Theory of Relativity and the Laws of Gravitation, valid in this context and corroborated by experimental proofs turning to experience, constitute a method which combines "Wesenanalyse" with "mathematische Konstruktion" of convincing and excellent exemplarity». This conviction has conducted him to a close collaboration with A. Einstein (documented by punctual correspondence) for the decisive formulation of the "General Theory of Relativity", but also of the Theory of unified Field of Gravitation and Electromagnetism and therefore the following formulation of some fundamental principles of Quantum Physics. So Weyl's theoretical formation was marked by the devotion toward a mathematical formalization ("mathematische Konstruktion") of physical phenomena, reporting each of them to the causal structure of the "mathematical thinking" and geometry, contemporarely to a strong inclination toward the phenomenological "Analysis of essence". He brings really a notable quantity of considerations in that 1954 essay by the point of view of the decisive role that the "pure Phenomenology" of Edmund Husserl developed in the determination of his scientific activity.

    2000-09-01

    The authors examined the phenomenology of bibliotherapy and its effects in changing preservice teachers' punitive attitudes toward children. Participants (N = 29) were enrolled in a university course (Introduction to Emotional Disturbance). Five books by Torey Hayden, autobiographical accounts of teaching and building relationships with students with emotional and behavioral disorders, were read and discussed within the framework of group bibliotherapy. Participants completed a self-report rating form measuring their tendency toward punitiveness during the first and last weeks of the 15-week semester. Participants also completed a questionnaire measuring the bibliotherapeutic impact of reading Hayden's texts, and they kept journals about the experience of reading Hayden. Comparison of the group's pre- and post-measures on punitiveness showed a small, albeit significant decrease in punitiveness; decreased punitiveness was associated with the therapeutic impact of reading Hayden. Phenomenological analysis of the participants' journal entries revealed that the structure of the experience of reading Hayden was one of identification with the protagonist, leading to emotional and cognitive learning.

  9. Aspects Of Grand Unified And String Phenomenology

    CERN Document Server

    Walker, J W

    2005-01-01

    Explored in this report is the essential interconnectedness of Grand Unified and String Theoretic Phenomenology. In order to extract a modeled connection to low-energy physics from the context of superstring theory, it is presently necessary to input some preferred region of parameter space in which to search. This need may be well filled by a parallel study of Grand Unification, which is by contrast in immediate proximity to a wealth of experimental data. The favored GUT so isolated may then reasonably transfer this phenomenological correlation to a string embedding, receiving back by way of trade a greater sense of primary motivation, and potentially enhanced predictability for parameters taken as input in a particle physics context. The Flipped SU(5) GUT will be our preferred framework in which to operate and first receives an extended study in a non-string derived setting. Of particularly timely interest are predictions for super-particle mass ranges and the interrelated question of proton decay lifetime....

  10. Resurrecting No-Scale Supergravity Phenomenology

    Ellis, John; Olive, Keith A

    2010-01-01

    In the context of phenomenological models in which the soft supersymmetry-breaking parameters of the MSSM become universal at some unification scale, M_{in}, above the GUT scale, \\mgut, it is possible that all the scalar mass parameters m_0, the trilinear couplings A_0 and the bilinear Higgs coupling B_0 vanish simultaneously, as in no-scale supergravity. Using these no-scale inputs in a renormalization-group analysis of the minimal supersymmetric SU(5) GUT model, we pay careful attention to the matching of parameters at the GUT scale. We delineate the region of M_{in}, m_{1/2} and \\tan \\beta where the resurrection of no-scale supergravity is possible, taking due account of the relevant phenomenological constraints such as electroweak symmetry breaking, m_h, b \\to s \\gamma, the neutralino cold dark matter density \\ohsq and g_\\mu - 2.

    Directory of Open Access Journals (Sweden)

    Dan Zahavi

    2011-02-01

    Full Text Available Drawing on the work of Scheler, Heidegger, Merleau-Ponty, Husserl and Sartre, this article presents an overview of some of the diverse approaches to intersubjectivity that can be found in the phenomenological tradition. Starting with a brief description of Scheler’s criticism of the argument from analogy, the article continues by showing that the phenomenological analyses of intersubjectivity involve much more than a ‘solution’ to the ‘traditional’ problem of other minds. Intersubjectivity doesn’t merely concern concrete faceto-face encounters between individuals. It is also something that is at play in simple perception, in tool-use, in emotions, drives and different types of self-awareness. Ultimately, the phenomenologists would argue that a treatment of intersubjectivity requires a simultaneous analysis of the relationship between subjectivity and world. It is not possible simply to insert intersubjectivity somewhere within an already established ontology; rather, the three regions ‘self’, ‘others’, and ‘world’ belong together; they reciprocally illuminate one another, and can only be understood in their interconnection.

    We present the second multi-frequency radio detection of a reverse shock in a γ-ray burst. By combining our extensive radio observations of the Fermi-Large Area Telescope γ-ray burst 160509A at z = 1.17 up to 20 days after the burst with Swift X-ray observations and ground-based optical and near-infrared data, we show that the afterglow emission comprises distinct reverse shock and forward shock contributions: the reverse shock emission dominates in the radio band at ≲10 days, while the forward shock emission dominates in the X-ray, optical, and near-infrared bands. Through multi-wavelength modeling, we determine a circumburst density of {n}0≈ {10}-3 {{cm}}-3, supporting our previous suggestion that a low-density circumburst environment is conducive to the production of long-lasting reverse shock radiation in the radio band. We infer the presence of a large excess X-ray absorption column, N H ≈ 1.5 × 1022 {{cm}}-2, and a high rest-frame optical extinction, A V ≈ 3.4 mag. We identify a jet break in the X-ray light curve at {t}{jet}≈ 6 {days}, and thus derive a jet opening angle of {θ }{jet}≈ 4^\\circ , yielding a beaming-corrected kinetic energy and radiated γ-ray energy of {E}{{K}}≈ 4× {10}50 erg and {E}γ ≈ 1.3× {10}51 erg (1-104 keV, rest frame), respectively. Consistency arguments connecting the forward shocks and reverse shocks suggest a deceleration time of {t}{dec} ≈ 460 s ≈ T 90, a Lorentz factor of {{Γ }}({t}{dec})≈ 330, and a reverse-shock-to-forward-shock fractional magnetic energy density ratio of {R}{{B}}\\equiv {ɛ }{{B},{RS}}/{ɛ }{{B},{FS}}≈ 8. Our study highlights the power of rapid-response radio observations in the study of the properties and dynamics of γ-ray burst ejecta.

    Dosne Pasqualini, C

    1998-01-01

    The concept of shock and its close relationship with that of stress dates back to the experiments of Hans Selye initiated in 1936 at McGill University in Montreal, with whom I collaborated between 1939 and 1942. It was demonstrated that the General Adaptation Syndrome begins with an Alarm Reaction, which consists of a Stage of Shock and one of Counter-Shock, followed by a Stage of Adaptation and finally a Stage of Exhaustion. My Ph.D. thesis concluded that shock was due to an adrenal insufficiency postulating that active metabolic processes drain the body of certain essential compounds the lack of which causes shock. My interest in the role of the glucose metabolism in shock led me to work with Bernardo Houssay in 1942 at the Institute of Physiology of the University of Buenos Aires and in 1944 with C.N.H. Long at Yale University. There I developed a method for the induction of hemorrhagic shock in the guinea pig with 94% lethality; curiously, the administration of 200 mg of ascorbic acid prevented death. Upon my return to Buenos Aires, these results were confirmed and moreover, it was demonstrated that the administration of cortisone led to 40% survival of the animals while desoxycorticosterone had no effect. At the time, no explanation was available but to-day, half a century later, this Symposium should be able to explain the mechanisms leading to death by hemorrhagic shock.

    Extracorporeal shock waves have revolutionized urological stone treatment. Nowadays shock waves are widely used in orthopedics, too. This article reviews the applications of extracorporeal shock waves on bone and adjacent soft tissue. The osteoneogenetic effect of extracorporeal shock waves has been proven and can be used to treat pseudarthrosis with a success rate of around 75%. Shock waves have a positive effect in tennis and golfer's elbow, calcaneal spur, and the complex called "periarthritis humero-scapularis." The mechanism for this is not yet known, and results from large prospective and randomized studies are still lacking. However, the treatment has been performed many thousands of times. In patients in whom conservative treatment has failed surgery used to be the only choice, but its success rate barely exceeds that of shock wave therapy and surgery can still be done if shock wave therapy fails. Extracorporeal shock waves will have an impact on orthopedics comparable to its effect in urology. Scientific evaluations, professional certifications, quality assurance and reimbursement issues present great challenges.

    Shock curvatures are related to pressure gradients, streamline curvatures and vorticity in flows with planar and axial symmetry. Explicit expressions, in an influence coefficient format, are used to relate post-shock pressure gradient, streamline curvature and vorticity to pre-shock gradients and shock curvature in steady flow. Using higher order, von Neumann-type, compatibility conditions, curved shock theory is applied to calculate the flow near singly and doubly curved shocks on curved surfaces, in regular shock reflection and in Mach reflection. Theoretical curved shock shapes are in good agreement with computational fluid dynamics calculations and experiment.

  12. Some reflections on clinical supervision: an existential-phenomenological paradigm.

    Science.gov (United States)

    Jones, A

    1998-03-01

    This paper reviews psychotherapy, counselling, and nursing literature related to ideas of clinical supervision and attempts to illuminate areas important to effective health related practice and specifically palliative care. Included are explorations of existentialism, phenomenology, existential phenomenology and psychoanalytical concepts. The phenomenological idea of lived experience is outlined and the Heideggerian notion of authenticity is explored in context. The paper also examines dynamic forces such as hope, trust and personal values that might influence clinical supervision design and so inform a framework for practice. An existential-phenomenological method of supervision is offered as one basis for professional practice. The central recommendation of this paper is, however, to identify relevant value and belief systems to direct clinical supervision. Nursing models might appropriately instruct approaches to supervision. The writer considers the phenomenological idea of the lived experiences as a means by which to at once capture the essence of palliative care nursing and guide the supervision towards the existential idea of authenticity.

  13. Phenomenological Justification of Theory of Time

    Directory of Open Access Journals (Sweden)

    Perminov V. Ya.

    2013-01-01

    Full Text Available The article exposes Husserl’s theory of time and provides its detailed comparison with theories of time of I. Kant and F. Brentano. The author first examines the general principles of the phenomenological theory of consciousness, and then analyzes the time concept of F. Brentano and Husserl’s criticism of these ideas, and eventually makes a comparison of Husserl’s and Kant’s theories of time. The author is inclined to conclude that progress in the interpretation of the time made by Husserl, is largely external, based on unacceptable epistemological principles. Critique of these principles the author plans to carry out in one of the next issues of the magazine.

    Rattazzi, Riccardo; Wells, J D; Rattazzi, Riccardo; Strumia, Alessandro; Wells, James D.

    2000-01-01

    We explore the phenomenology of a class of models with anomaly-mediated supersymmetry breaking. These models retain the successful flavor properties of the minimal scenario while avoiding the tachyons. The mass spectrum is predicted in terms of a few parameters. However various qualitatively different spectra are possible, often strongly different from the ones usually employed to explore capabilities of new accelerators. One stable feature is the limited spread of the spectrum, so that squarks and gluinos could be conceivably produced at TEVII. The lightest superpartner of standard particles is often a charged slepton or a neutral higgsino. It behaves as a stable particle in collider experiments but it decays at or before nucleosynthesis. We identify the experimental signatures at hadron colliders that can help distinguish this scenario from the usual ones.

  15. The Phenomenology of Small-Scale Turbulence

    Science.gov (United States)

    Sreenivasan, K. R.; Antonia, R. A.

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

  16. E6SSM vs MSSM gluino phenomenology

    CERN Document Server

    Svantesson, Patrik; Hall, Jonathan P; King, Stephen F

    2012-01-01

    The E6SSM is a promising model based on the group E6, assumed to be broken at the GUT scale, leading to the group SU(3)\\times SU(2)\\times U(1)\\times U(1)' at the TeV scale. It gives a solution to the MSSM {\\mu}-problem without introducing massless axions, gauge anomalies or cosmological domain walls. The model contains three families of complete 27s of E6, giving a richer phenomenology than the MSSM. The E6SSM generically predicts gluino cascade decay chains which are about 2 steps longer than the MSSM's due to the presence of several light neutralino states. This implies less missing (and more visible) transverse momentum in collider experiments and kinematical distributions such as M_eff are different. Scans of parameter space and MC analysis suggest that current SUSY search strategies and exclusion limits have to be reconsidered.

  17. Phenomenology of muon-induced neutron yield

    Science.gov (United States)

    Malgin, A. S.

    2017-07-01

    The cosmogenic neutron yield Yn characterizes the ability of matter to produce neutrons under the effect of cosmic ray muons with spectrum and average energy corresponding to an observation depth. The yield is the basic characteristic of cosmogenic neutrons. The neutron production rate and neutron flux both are derivatives of the yield. The constancy of the exponents α and β in the known dependencies of the yield on energy Yn∝Eμα and the atomic weight Yn∝Aβ allows one to combine these dependencies in a single formula and to connect the yield with muon energy loss in matter. As a result, the phenomenological formulas for the yields of muon-induced charged pions and neutrons can be obtained. These expressions both are associated with nuclear loss of the ultrarelativistic muons, which provides the main contribution to the total neutron yield. The total yield can be described by a universal formula, which is the best fit of the experimental data.

  18. [Phenomenology of multiculturalism and intercultural pluralism].

    2012-01-01

    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.

  1. Hypnosis phenomenology and the neurobiology of consciousness.

    Science.gov (United States)

    Rainville, Pierre; Price, Donald D

    2003-04-01

    Recent developments in the philosophical and neurobiological studies of consciousness provide promising frameworks to investigate the neurobiology of hypnosis. A model of consciousness phenomenology is described to demonstrate that the experiential dimensions characterizing hypnosis (relaxation and mental ease, absorption, orientation and monitoring, and self-agency) reflect basic phenomenal properties of consciousness. Changes in relaxation-mental ease and absorption, produced by standard hypnotic procedures, are further associated with changes in brain activity within structures critically involved in the basic representation of the body-self and the regulation of states of consciousness. The combination of experiential and modern brain imaging methods offers a unique perspective on hypnotic phenomena and provides new observations consistent with the proposition that hypnosis is an altered state of consciousness.

  2. Extended inertial range phenomenology of magnetohydrodynamic turbulence

    Science.gov (United States)

    Matthaeus, William H.; Zhou, YE

    1989-01-01

    A phenomenological treatment of the inertial range of isotropic statistically steady magnetohydrodynamic turbulence is presented, extending the theory of Kraichnan (1965). The role of Alfven wave propagation is treated on equal footing with nonlinear convection, leading to a simple generalization of the relations between the times characteristic of wave propagation, convection, energy transfer, and decay of triple correlations. The theory leads to a closed-form steady inertial range spectral law that reduces to the Kraichnan and Kolmogorov laws in appropriate limits. The Kraichnan constant is found to be related in a simple way to the Kolmogorov constant; for typical values of the latter constant, the former has values in the range 1.22-1.87. Estimates of the time scale associated with spectral transfer of energy also emerge from the new approach, generalizing previously presented 'golden rules' for relating the spectral transfer time scale to the Alfven and eddy-turnover time scales.

    Gregory Cameron

    2011-12-01

    Full Text Available “Politics and the Internet” is a critique of the political potential of the internet from the perspective of Husserl’s discussion of intersubjectivity and objectivity in Cartesian Meditations and Origins of Geometry. Unlike other critiques of the internet from a phenomenological perspective, this paper does not consider the limitations of internet communication from the perspective of the body. Here, rather, the prime concern is with the constitution of objectivity and the ways in which the internet limits this constitution. The paper builds towards a consideration of the essential role of objectivity as a condition of possibility for politics and community. Implicit in the argument is a defence of print and broadcast media.

    The classical Hamiltonian of the interacting boson model is defined and expressed in terms of the conventional quadrupole variables. This is used in the analyses of the dynamics in the various limits of the model. The purpose is to determine the range and the features of the collective phenomena which the interacting boson model is capable of describing. In the commonly used version of the interacting boson model with one type of the s and d bosons and quartic interactions, this capability has certain limitations and the model should be used with care. A more sophisticated version of the interacting boson model with neutron and proton bosons is not discussed.

    Nayani, T H; David, A S

    1996-01-01

    A comprehensive semi-structured questionnaire was administered to 100 psychotic patients who had experienced auditory hallucinations. The aim was to extend the phenomenology of the hallucination into areas of both form and content and also to guide future theoretical development. All subjects heard 'voices' talking to or about them. The location of the voice, its characteristics and the nature of address were described. Precipitants and alleviating factors plus the effect of the hallucinations on the sufferer were identified. Other hallucinatory experiences, thought insertion and insight were examined for their inter-relationships. A pattern emerged of increasing complexity of the auditory-verbal hallucination over time by a process of accretion, with the addition of more voices and extended dialogues, and more intimacy between subject and voice. Such evolution seemed to relate to the lessening of distress and improved coping. These findings should inform both neurological and cognitive accounts of the pathogenesis of auditory hallucinations in psychotic disorders.

    2015-12-01

    Paul Ricoeur's hermeneutic phenomenology has proved to be very helpful in guiding nursing researchers' qualitative analysis of interview transcripts. Modifying Ricoeur's philosophy, a number of nursing researchers have developed their own interpretive methods and shared them, along with their experience, with research community. Major contributors who published papers directly presenting their modifications of Ricoeur's theory include Rene Geanellos (2000), Lena Wiklund, Lisbet Lindholm and Unni Å. Lindström (2002), Anders Lindseth and Astrid Norberg (2004) and Pia Sander Dreyer and Birthe D Pedersen (2009). The aim of this article was to delineate differences among these methods. Descriptive presentation of each method side by side makes clear the differences among them. In addition, Ricoeur's hermeneutic theory is portrayed and compared with the modifications. It is believed that differences that are found can stimulate further thoughts on how to apply Ricoeur's theory in qualitative research in nursing.

    give a brief overview of the phenomenology related to the measurements of the last unknown lepton mixing angle !13, CP violation (CPV) in neutrino os- cillations, and the neutrino mass hierarchy (MH). Sensitivities of upcoming reactor and accelerator experiments to !13 are discussed, showing that within a few years values of sin2 2!13 ! 10−2 will be probed, while CPV andMH mea- surements will be very difÞcult with that generation of experiments. I make some selected remarks on CPV andMH determinations with a subsequent gen- eration of experiment consisting of a high precision/high luminosity oscillation facility. In particular, I emphasize the possibility to explore synergies of such an advanced accelerator facility with a huge multi-purpose detector.

As a result, this paper embraces embodied methodologies. It integrates audio-visual impressionistic tales and netnographic snippets to shape its multisensory exploration of an under-researched European tourism and train...

    2015-11-01

    The study explored factors leading to chief nursing officer (CNO) sustainment in the professional practice of nurse executive leadership. CNOs are expected to lead adaptations in care delivery in this current era of healthcare reform, requiring a multitude of new leadership skills. Exploration is needed to understand barriers to longevity, which prevent consistency of leadership and execution of vision. Twenty CNOs were interviewed to determine the lived experience related to the phenomena of role sustainment. An interpretative phenomenological analysis approach was used. Six themes emerged describing sustainment. These are as follows: loving the profession, having a broader impact, reflecting on one's own work, learning to manage conflict, maintaining work/life balance, and working with supportive leaders. The desire and passion for nurse executive leadership must be enhanced through education and competencies that emerged in this study and include strategic processing, mindful reflection, and resiliency training.

    Inner speaking is a common and widely discussed phenomenon of inner experience. Based on our studies of inner experience using Descriptive Experience Sampling (a qualitative method designed to produce high fidelity descriptions of randomly selected pristine inner experience), we advance an initial phenomenology of inner speaking. Inner speaking does occur in many, though certainly not all, moments of pristine inner experience. Most commonly it is experienced by the person as speaking in his or her own naturally inflected voice but with no sound being produced. In addition to prototypical instances of inner speaking, there are wide-ranging variations that fit the broad category of inner speaking and large individual differences in the frequency with which individuals experience inner speaking. Our observations are discrepant from what many have said about inner speaking, which we attribute to the characteristics of the methods different researchers have used to examine inner speaking.

  11. Effective Lagrangians and Light Gravitino Phenomenology

    Luty, M A; Luty, Markus A.; Ponton, Eduardo

    1998-01-01

    We construct the low-energy effective lagrangian for supersymmetry breaking models with a light gravitino. Our effective lagrangian is written in terms of the spin-1/2 Goldstino (the longitudinal component of the gravitino) transforming under a non-linear realization of supersymmetry. The Goldstino is derivatively coupled. We use this lagrangian to place bounds on the supersymmetry breaking scale \\sqrt{F} from Goldstino phenomenology. The most stringent bounds come from the coupling of a single photon to Goldstino pairs. For gauge-mediated models, this coupling arises at one loop in the effective lagrangian, and supernova cooling allows \\sqrt{F} > 610 GeV or \\sqrt{F} 140 GeV for tan\\beta = 2.

    We show that an invariant an universal length scale can be consistently introduced in a generally covariant theory through the gravitational sector using the Palatini approach. The resulting theory is able to capture different aspects of quantum gravity phenomenology in a single framework. In particular, it is found that in this theory field excitations propagating with different energy-densities perceive different background metrics, which is a fundamental characteristic of the DSR and Rainbow Gravity approaches. We illustrate these properties with a particular gravitational model and explicitly show how the soccer ball problem is avoided in this framework. The isotropic and anisotropic cosmologies of this model also avoid the big bang singularity by means of a big bounce.

  13. Differentiating between descriptive and interpretive phenomenological research approaches.

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

    Full Text Available Sotiria Gkisioti, Spyros D MentzelopoulosDepartment of Intensive Care Medicine, University of Athens Medical School, Evaggelismos General Hospital, Athens, GreeceAbstract: Shock means inadequate tissue perfusion by oxygen-carrying blood. In vasogenic shock, this circulatory failure results from vasodilation and/or vasoplegia. There is vascular hyporeactivity with reduced vascular smooth muscle contraction in response to α1 adrenergic agonists. Considering vasogenic shock, one can understand its utmost importance, not only because of its association with sepsis but also because it can be the common final pathway for long-lasting, severe shock of any cause, even postresuscitation states. The effective management of any patient in shock requires the understanding of its underlying physiology and pathophysiology. Recent studies have provided new insights into vascular physiology by revealing the interaction of rather complicated and multifactorial mechanisms, which have not been fully elucidated yet. Some of these mechanisms, such as the induction of nitric oxide synthases, the activation of adenosine triphosphate-sensitive potassium channels, and vasopressin deficiency, have gained general acceptance and are considered to play an important role in the pathogenesis of vasodilatory shock. The purpose of this review is to provide an update on the pathogenesis of vasogenic shock.Keywords: nitric oxide synthases, KATP channels, vasopressin, H2S, vasoplegic syndrome

    Full Text Available Mika Elo is a postdoctoral researcher and lecturer in visual culture at Aalto University School of Arts, Design and Architecture (Aalto-ARTS, Helsinki. His research interests include theory of photographic media, philosophical media theory, and artistic research. He is participating in discussions in these areas in the capacity of curator, visual artist and researcher. He has published articles in Finnish, German, and English among others on Benjamin, Nancy, artistic research and photography theory. His doctoral thesis Valokuvan medium [The Medium of Photography] was published in Finnish in 2005 (Tutkijaliitto, Helsinki. In 2009–2011 he worked in the Figures of Touch research project (figuresoftouch.com, and since 2011 he is the director of Media Aesthetics research group at Aalto-ARTS, Department of Media.Author Biography The article reflects on digitality and interface design in terms of the multiple senses of touch. Touching is presented as a “pathic” sense of being exposed, which implies that touching exceeds the tactile and even the phenomenal world. A particular focus is set on Aristotle's and Husserl's ways of thematizing the sense of touch. In this way, two extremes of the phenomenological thinking of touching are articulated: touching as an indistinct and heterogeneous constituent of sensitivity and touching as the guarantor of immediacy of the sense experience. Referring to Derrida's critical notes concerning haptocentrism, the article attempts to problematize the hand and the finger as phenomenological figures of touch and as holds of haptic realism. The article concludes that insofar as digital interface design aims at haptic realism it conceives of the sense of touch in terms of narcissistic feedback and thus tends to conceal the pathic moment of touching.

    In the context of phenomenological models in which the soft supersymmetry-breaking parameters of the MSSM become universal at some unification scale, M{sub in}, above the GUT scale, M{sub GUT}, it is possible that all the scalar mass parameters m{sub 0}, the trilinear couplings A{sub 0} and the bilinear Higgs coupling B{sub 0} vanish simultaneously, as in no-scale supergravity. Using these no-scale inputs in a renormalisation-group analysis of the minimal supersymmetric SU(5) GUT model, we pay careful attention to the matching of parameters at the GUT scale. We delineate the region of M{sub in}, m{sub 1/2} and tan {beta} where the resurrection of no-scale supergravity is possible, taking due account of the relevant phenomenological constraints such as electroweak symmetry breaking, m{sub h},b {yields}s {gamma}, the neutralino cold dark matter density {omega}{sub {chi}} h {sup 2} and g{sub {mu}} -2. No-scale supergravity survives in an L-shaped strip of parameter space, with one side having m{sub 1/2}>or similar 200 GeV, the second (orthogonal) side having M{sub in}>or similar 5 x 10 {sup 16} GeV. Depending on the relative signs and magnitudes of the GUT superpotential couplings, these may be connected to form a triangle whose third side is a hypotenuse at larger M{sub in}, m{sub 1/2} and tan {beta}, whose presence and location depend on the GUT superpotential parameters. We compare the prospects for detecting sparticles at the LHC in no-scale supergravity with those in the CMSSM and the NUHM. (orig.)

  17. The phenomenology of the intersubjective impairment.

    2016-08-01

    Several studies suggest that the disorders of the self include a disturbance of the most elementary component of self - the minimal self. Characterizing these disorders and understanding the mechanisms involved remain a challenge to medical epistemology and health care professionals. In the present work, I bring together concepts of different fields, such as neuroscience, epistemology and phenomenology. The main goal is to show that the second-person perspective can be used to point out particular features of social cognition and its related psychopathology. Taking the hypothesis that the second-person perspective is the congruence point between an objective process and the subjective experience, I will attempt to explain schizophrenia as a self-related deficit, first in the light of the first-person and the third-person perspective and afterward, in the light of the poorly less understood second-person perspective. On the one hand, the first-person experience is correlated both with space and time. In fact, psychiatric patients report subjective experiences that can be understood within research on the bodily self, such as (1) spatially incongruent proprioception and (2) impaired sense of time as the basic mechanism that allows conscious experience. On the other hand, the second-person approach has already begun to prove productive within social cognition research, pointing out the importance of experiencing and interacting with others as our primarily way well-being. I will phenomenological analyse subjective and intersubjective experience in the disorders of the self and derive practical consequences to evidence-based medicine.

    A shock tube facility for generating a cylindrical converging shock wave is developed in this work. Based on the shock dynamics theory, a specific wall profile is designed for the test section of the shock tube to transfer a planar shock into a cylindrical one. The shock front in the converging part obtained from experiment presents a perfect circular shape, which proves the feasibility and reliability of the method. The time variations of the shock strength obtained from numerical simulation, experiment, and theoretical estimation show the desired converging effect in the shock tube test section. Particular emphasis is then placed on the problem of shock-interface interaction induced by cylindrical converging shock waves. For this purpose, membrane-less gas cylinder is adopted to form the interface between two different fluids while the laser sheet technique to visualize the flow field. The result shows that it is convenient to perform such experiments in this facility.

  1. Collisionless parallel shocks

    1993-01-01

    Consideration is given to a collisionless parallel shock based on solitary-type solutions of the modified derivative nonlinear Schroedinger equation (MDNLS) for parallel Alfven waves. The standard derivative nonlinear Schroedinger equation is generalized in order to include the possible anisotropy of the plasma distribution and higher-order Korteweg-de Vies-type dispersion. Stationary solutions of MDNLS are discussed. The anisotropic nature of 'adiabatic' reflections leads to the asymmetric particle distribution in the upstream as well as in the downstream regions of the shock. As a result, nonzero heat flux appears near the front of the shock. It is shown that this causes the stochastic behavior of the nonlinear waves, which can significantly contribute to the shock thermalization.

    The interaction between a supersonic stellar wind and a (super-)sonic interstellar wind has recently been viewed with new interest. We here first give an overview of the modeling, which includes the heliosphere as an example of a special astrosphere. Then we concentrate on the shock structures of fluid models, especially of hydrodynamic (HD) models. More involved models taking into account radiation transfer and magnetic fields are briefly sketched. Even the relatively simple HD models show a rich shock structure, which might be observable in some objects. We employ a single fluid model to study these complex shock structures, and compare the results obtained including heating and cooling with results obtained without these effects. Furthermore, we show that in the hypersonic case valuable information of the shock structure can be obtained from the Rankine-Hugoniot equations. We solved the Euler equations for the single fluid case and also for a case including cooling and heating. We also discuss the analytic...

  4. On the phenomenology of empathy in nursing: empathy or sympathy?

    Science.gov (United States)

    Yegdich, T

    1999-07-01

    In her recent phenomenological study Baillie attempted to describe the essential structure of empathy in surgical nursing. The study is important in that it utilizes a qualitative research method to investigate the phenomena of empathy, in contrast to previous quantitative studies. Although the phenomenological approach is clearly identified and ascribed to Husserl as the founder of the phenomenological movement, as well as utilizing the peculiarly Husserlian notion of bracketing, or epoché, in an attempt to describe the essence (another Husserlian objective) of the phenomenon under investigation (empathy), the research method does not reflect Husserl's philosophy. The results reflect nurses' subjective views on empathy, an exercise consistent with the nurse-phenomenologists quoted, who without exception, all believe Husserlian phenomenology concerns itself with subjective experience. However, in seeking the essence of phenomena unclouded by subjective opinion, Husserl stands in contrast to nursing interpretations of phenomenology's famous catch phrase, 'back to the things themselves' (zu den Sachen selbst). Nurse-phenomenologists have misunderstood the intention of Husserlian phenomenology, and despite their opposition to traditional scientific methods, are still mired in the Kantian notion of science as a reality independent of mind. A theme consistent with the 'things-in-themselves', not the things themselves. As such, nursing's use of the phenomenological method is questionable, and therefore the research findings on the phenomenon of empathy need to be reformulated. Interestingly, the phenomenon of empathy challenges us to question such underlying assumptions on how we view the world.

The study used phenomenological design and descriptive phenomenological approach was adapted. The participants were selected by using homogenous sampling strategy and data were collected through in depth interviews from six volunteer pre-service teachers which are a woman and five men. In analysis of the research data, thematic analysis approach was utilized. As a result of the analysis, two themes were constructed to explain the reasons for cheating that are personal factors and environmental factors. The personal factors are comprised of personal characteristics, academic gains and insufficient self-perception. The environmental factors affecting cheating behaviors are instructor’s attitudes and behaviors, exam-based evaluation system, the role of courses, peer effect, institutional features and family expectations.Keywords: Cheating, preservice teachers, qualitative research, phenomenology ÖzBu araştırmanın amacı öğretmen adaylarının kopya çekme davranışlarının nedenlerini incelemektir.

    Full Text Available In May 2004 the Balì Museum, Planetarium and interactive science museum, was opened to the public in Italy: 35 hands-on exhibits designed according to the interactive tradition of the Exploratorium in San Francisco, an astronomic observatory for educational activities, a Planetarium with 70 places. With a total investment of about three million euros, about two thirds of which were spent on restructuring the splendid eighteenth-century villa in which it is housed, the undertaking may be considered a small one in comparison with other European science centres. Three million euros: perhaps enough to cover the cost of only the splendid circular access ramp to the brand-new Cosmocaixa in Barcelona, an investment of one hundred million euros. But the interesting aspect of the story of the Balì Museum (but also of other Italian stories, as we shall see lies in the fact that this lively and advanced science centre stands in the bucolic region of the Marches, next to a small town of only 800 inhabitants (Saltara, in the Province of Pesaro and Urbino, in a municipal territory that has a total of 5000. Whereas in Italy the projects for science centres comparable with the Catalan one, for example projects for Rome and Turin, never get off the ground, smaller ones are opening in small and medium-sized towns: why is this? And what does the unusual location of the centres entail for science communication in Italy? This Focus does not claim to tell the whole truth about Italian interactive museums, but it does offer some phenomenological cues to open a debate on the cultural, economic and political premises that favour their lives.

    Hermeneutic phenomenology has been used widely by researchers to understand lived experiences. This methodology asserts that individual people are as unique as their life stories. The practice of midwifery is underpinned by a philosophy that values women and the uniqueness of their child-bearing journey. The tenets of hermeneutics phenomenology align with those of contemporary midwifery practice, making it a useful research methodology for providing insights into issues relevant to the profession. The purpose of this paper is to unravel some foundational concepts of hermeneutic phenomenology and recommend it as a methodology of choice for midwives to apply to their application to midwifery-in-action.

    For a population with any given number of types, we construct a new multivariate Moran process with frequency-dependent selection and establish, analytically, a correspondence to equilibrium Lotka-Volterra phenomenology. This correspondence, on the one hand, allows us to infer the phenomenology of our Moran process based on much simpler Lokta-Volterra phenomenology and, on the other, allows us to study Lotka-Volterra dynamics within the finite populations of a Moran process. Applications to community ecology, population genetics, and evolutionary game theory are discussed.

  15. The phenomenology of maverick dark matter

    Science.gov (United States)

    Krusberg, Zosia Anna Celina

    Astrophysical observations from galactic to cosmological scales point to a substantial non-baryonic component to the universe's total matter density. Although very little is presently known about the physical properties of dark matter, its existence offers some of the most compelling evidence for physics beyond the standard model (BSM). In the weakly interacting massive particle (WIMP) scenario, the dark matter consists of particles that possess weak-scale interactions with the particles of the standard model, offering a compelling theoretical framework that allows us to understand the relic abundance of dark matter as a natural consequence of the thermal history of the early universe. From the perspective of particle physics phenomenology, the WIMP scenario is appealing for two additional reasons. First, many theories of BSM physics contain attractive WIMP candidates. Second, the weak-scale interactions between WIMPs and standard model particles imply the possibility of detecting scatterings between relic WIMPs and detector nuclei in direct detection experiments, products of WIMP annihilations at locations throughout the galaxy in indirect detection programs, and WIMP production signals at high-energy particle colliders. In this work, we use an effective field theory approach to study model-independent dark matter phenomenology in direct detection and collider experiments. The maverick dark matter scenario is defined by an effective field theory in which the WIMP is the only new particle within the energy range accessible to the Large Hadron Collider (LHC). Although certain assumptions are necessary to keep the problem tractable, we describe our WIMP candidate generically by specifying only its spin and dominant interaction form with standard model particles. Constraints are placed on the masses and coupling constants of the maverick WIMPs using the Wilkinson Microwave Anisotropy Probe (WMAP) relic density measurement and direct detection exclusion data from both

  16. The Phenomenology of Flipped SU(5)

    Science.gov (United States)

    Abel, S. A.

    1990-01-01

    Available from UMI in association with The British Library. In this thesis, I examine the phenomenology of the supersymmetric flipped SU(5) model. Such a model has been derived as a low energy approximation to heterotic string theory, probably with a 'no-scale' supersymmetry breaking mechanism. It is found that a large region of the flipped SU(5) parameter space predicts a satisfactory breaking down to the standard model on renormalization down to low energies. In particular it contains a number of phenomenological advantages over other GUT schemes, such as a natural Higg's doublet-triplet mass splitting, and a neutrino see-saw mechanism. Analysis of the neutrino sector shows that this model may allow rapid decays of the heavy neutrinos into lighter electron-neutrinos. This is due to new flavour changing couplings in the superpotential, which are included in the neutrino mass matrix. Such fast decays may be able to evade certain cosmological bounds, based on the standard inflationary scenarios and the observation of the 3K background radiation. Thus it is possible that neutrinos could form a substantial proportion of the dark matter in the Universe. Rare processes may be significantly enhanced in the flipped SU(5) scenario, due to new couplings whose off diagonal Kobayashi-Maskawa matrix elements need not be small. In particular, the gaugino-fermion-sfermion coupling may give important new flavour changing diagrams, since, after supersymmetry is broken, the fermions and sfermions are no longer simultaneously diagonalizable. This leads to the possibility of decays such as Z to bs and muto egamma being detected in the near future. In addition to this there are significant new contributions to the electric dipole moment of the neutron which may be as high as the present day limit of | d_ n| < 10^{-25}ecm. Support for this model may come from neutralino contributions to the number of 'neutrino species' measured in Z decays. Finally, the anomalous magnetic moment of the

    The dynamics of photoevaporated molecular clouds is determined by the ablative pressure acting on the ionization front. An important step in the understanding of the ensuing motion is to develop the linear stability theory for the initially flat front. Despite the simplifications introduced by the linearization, the problem remains quite complex and still draws a lot of attention. The complexity is related to the large number of effects that have to be included in the analysis: acceleration of the front, possible temporal variation of the intensity of the ionizing radiation, the tilt of the radiation flux with respect to the normal to the surface, and partial absorption of the incident radiation in the ablated material. In this paper, we describe a model where all these effects can be taken into account simultaneously, and a relatively simple and universal dispersion relation can be obtained. The proposed phenomenological model may prove to be a helpful tool in assessing the feasibility of the laboratory experiments directed towards scaled modeling of astrophysical phenomena.

  20. Dante's inferno: phenomenology of a strange passion.

    Dante's Inferno presents us with a spiritual adventure where the experience of wrath plays a crucial role. The infernal pilgrim's 'passage through wrath' is their only access to the lower part of Hell. Wrath - and the place where it is punished as a vice - occupy a very central position in the moral topography of Dante's Inferno: the Stygian Marsh, which defends the heart of Hell, its stronghold, and makes it inaccessible. Wrathfulness is situated at the borderline between 'carnal' and 'spiritual' sins, higher and lower Hell, weakness and wickedness of the will. What is the meaning of this situation? How is the sin of wrathfulness related to wrath as an expression of just indignation? How can the same passion have an angelical and an infernal face? What is anger's relation to reason? Does the trial gone through by the two pilgrims teach us something on the nature of this passion? Here are some questions which this paper tries to answer, thereby outlining a phenomenological theory of those passions which might be called 'dynamic'. Copyright 2000 S. Karger AG, Basel

  1. Phenomenological model for light-projectile breakup

    Kalbach, C.

    2017-01-01

    Background: Projectile breakup can make a large contribution to reactions induced by projectiles with mass numbers 2, 3, and 4, yet there is no global model for it and no clear agreement on the details of the reaction mechanism. Purpose: This project aims to develop a phenomenological model for light-projectile breakup that can guide the development of detailed theories and provide a useful tool for applied calculations. Method: An extensive database of double-differential cross sections for the breakup of deuterons, 3He ions, and α particles was assembled from the literature and analyzed in a consistent way. Results: Global systematics for the centroid energies, peak widths, and angular distributions of the breakup peaks have been extracted from the data. The dominant mechanism appears to be absorptive breakup, where the unobserved projectile fragment fuses with the target nucleus during the initial interaction. The global target-mass-number and incident-energy dependencies of the absorptive breakup cross section have also been determined, along with channel-specific normalization constants. Conclusions: Results from the model generally agree with the original data after subtraction of a reasonable underlying continuum. Absorptive breakup can account for as much as 50%-60% of the total reaction cross section.

  2. Phenomenology of Compositeness at the LHC

    CERN Document Server

    Salvioni, Ennio; Zwirner, Fabio

    The hierarchy problem of the weak scale calls for extensions of the Standard Model at the TeV, and thus within the reach of the CERN Large Hadron Collider (LHC). One of the best motivated proposals builds on the idea that the Higgs could be a composite pseudo-Nambu-Goldstone boson. In this thesis we discuss several topics in the phenomenology of composite Higgs models, concentrating mainly on LHC physics. In Chapter 1 we introduce the hierarchy problem and the essential features of viable theories of compositeness at the TeV scale. Chapter 2 is dedicated to a review of concrete constructions realizing the composite Higgs idea, focusing mostly on models with partial compositeness. In Chapter 3 we present the effective Lagrangians suited for describing the Higgs boson and the constraints placed by electroweak precision tests on their parameters. Motivated by hints in the experimental results, we also reconsider the possibility of custodial breaking in the couplings of the Higgs to the W and Z. Chapter 4 is devo...

    2016-01-01

    We present some of the topics covered in two lectures under the same title that was given at the "Summer School on High Energy Physics at the LHC: New trends in HEP" in Natal, Brazil. In this contribution we give a brief review on the application of perturbative QCD to the hard diffractive processes. Such reactions involving a hard scale can be understood in terms of quarks and gluons degrees of freedom and have become an useful tool for investigating the low-$x$ structure of the proton and the behavior of QCD in the high-density regime. We start using the information from the $ep$ collisions at HERA concerned to the inclusive diffraction to introduce the concept of diffractive parton distributions. Their interpretation in the resolved pomeron model is addressed and we discuss the limits of diffractive hard-scattering factorization for hadron-hadron collisions. Some examples of phenomenology for the diffractive production of $W/Z$, heavy $Q\\bar{Q}$ and quarkonium in hadron-hadron reactions are presented. We a...

  4. New Results in Light-Front Phenomenology

    The light-front quantization of gauge theories such as QCD in light-cone gauge provides a frame-independent wavefunction representation of relativistic bound states, simple forms for current matrix elements, explicit unitarity, and a trivial vacuum. The freedom to choose the light-like quantization four-vector provides an explicitly covariant formulation of light-front quantization and can be used to determine the analytic structure of light-front wave functions and to define a kinematical definition of angular momentum. The AdS/CFT correspondence of large $N_C$ supergravity theory in higher-dimensional anti-de Sitter space with supersymmetric QCD in 4-dimensional space-time has interesting implications for hadron phenomenology in the conformal limit, including an all-orders demonstration of counting rules for exclusive processes. String/gauge duality also predicts the QCD power-law behavior of light-front Fock-state hadronic wavefunctions with arbitrary orbital angular momentum at high momentum transfer. The...

  5. Phenomenology in minimal theory of massive gravity

    De Felice, Antonio

    2015-01-01

    We investigate the minimal theory of massive gravity (MTMG) recently introduced. After reviewing the original construction based on its Hamiltonian in the vielbein formalism, we reformulate it in terms of its Lagrangian in both the vielbein and the metric formalisms. It then becomes obvious that, unlike previous attempts in the literature, not only the potential but also the kinetic structure of the action is modified from the de Rham-Gabadadze-Tolley (dRGT) massive gravity theory. We confirm that the number of physical degrees of freedom in MTMG is two at fully nonlinear level. This proves the absence of various possible pathologies such as superluminality, acausality and strong coupling. Afterwards, we discuss the phenomenology of MTMG in the presence of a dust fluid. We find that on a flat homogeneous and isotropic background we have two branches. One of them (self-accelerating branch) naturally leads to acceleration without the genuine cosmological constant or dark energy. For this branch both the scalar ...

  6. Conciliating neuroscience and phenomenology via category theory.

    The paper discusses how neural and mental processes correlate for developing cognitive abilities like memory or spatial representation and allowing the emergence of higher cognitive processes up to embodied cognition, consciousness and creativity. It is done via the presentation of MENS (for Memory Evolutive Neural System), a mathematical methodology, based on category theory, which encompasses the neural and mental systems and analyzes their dynamics in the process of 'becoming'. Using the categorical notion of a colimit, it describes the generation of mental objects through the iterative binding of distributed synchronous assemblies of neurons, and presents a new rationale of spatial representation in the hippocampus (Gómez-Ramirez and Sanz, 2011). An important result is that the degeneracy of the neural code (Edelman, 1989) is the property allowing for the formation of mental objects and cognitive processes of increasing complexity order, with multiple neuronal realizabilities; it is essential "to explain certain empirical phenomena like productivity and systematicity of thought and thinking (Aydede 2010)". Rather than restricting the discourse to linguistics or philosophy of mind, the formal methods used in MENS lead to precise notions of Compositionality, Productivity and Systematicity, which overcome the dichotomic debate of classicism vs. connectionism and their multiple facets. It also allows developing the naturalized phenomenology approach asked for by Varela (1996) which "seeks articulations by mutual constraints between phenomena present in experience and the correlative field of phenomena established by the cognitive sciences", while avoiding their pitfalls.

    This project tackles the problem of conversion of validated a priori physics-based modeling capabilities, specifically those relevant to the analysis and interpretation of planetary atmosphere observations, to application-oriented software for use in science and science-support activities. The software package under development, named the Photochemical Phenomenology Modeling Tool (PPMT), has particular focus on the atmospheric remote sensing data to be acquired by the CIRS instrument during the CASSINI Jupiter flyby and orbital tour of the Saturnian system. Overall, the project has followed the development outline given in the original proposal, and the Year 1 design and architecture goals have been met. Specific accomplishments and the difficulties encountered are summarized in this report. Most of the effort has gone into complete definition of the PPMT interfaces within the context of today's IT arena: adoption and adherence to the CORBA Component Model (CCM) has yielded a solid architecture basis, and CORBA-related issues (services, specification options, development plans, etc.) have been largely resolved. Implementation goals have been redirected somewhat so as to be more relevant to the upcoming CASSINI flyby of Jupiter, with focus now being more on data analysis and remote sensing retrieval applications.

  8. Phenomenology of Dirac Neutralino Dark Matter

    Energy Technology Data Exchange (ETDEWEB)

    Buckley, Matthew R.; Hooper, Dan; Kumar, Jason

    2013-09-01

    In supersymmetric models with an unbroken R-symmetry (rather than only R-parity), the neutralinos are Dirac fermions rather than Majorana. In this article, we discuss the phenomenology of neutralino dark matter in such models, including the calculation of the thermal relic abundance, and constraints and prospects for direct and indirect searches. Due to the large elastic scattering cross sections with nuclei predicted in R-symmetric models, we are forced to consider a neutralino that is predominantly bino, with very little higgsino mixing. We find a large region of parameter space in which bino-like Dirac neutralinos with masses between 10 and 380 GeV can annihilate through slepton exchange to provide a thermal relic abundance in agreement with the observed cosmological density, without relying on coannihilations or resonant annihilations. The signatures for the indirect detection of Dirac neutralinos are very different than predicted in the Majorana case, with annihilations proceeding dominately to $\\tau^+ \\tau^-$, $\\mu^+ \\mu^-$ and $e^+ e^-$ final states, without the standard chirality suppression. And unlike Majorana dark matter candidates, Dirac neutralinos experience spin-independent scattering with nuclei through vector couplings (via $Z$ and squark exchange), leading to potentially large rates at direct detection experiments. These and other characteristics make Dirac neutralinos potentially interesting within the context of recent direct and indirect detection anomalies. We also discuss the case in which the introduction of a small Majorana mass term breaks the $R$-symmetry, splitting the Dirac neutralino into a pair of nearly degenerate Majorana states.

    2013-01-01

    We review how quark models are able to describe the phenomenology of the charm meson sector. The spectroscopy and decays of charmonium and open charm mesons are described in a particular quark model and compared with the data and the results of other existing models in the literature. A quite reasonable global description of the heavy meson spectra is reached. A new assignment of the $\\psi(4415)$ resonance as a 3D state leaving aside the 4S state to the X(4360) is tested through the analysis of the resonance structure in $e^{+}e^{-}$ exclusive reactions around the $\\psi(4415)$ energy region. We make tentative assignments of some of the $XYZ$ mesons. To elucidate the structure of the $1^{+}$ $c\\bar{s}$ states, i.e. $D_{s1}(2460)$ and $D_{s1}(2536)$, we study the strong decay properties of the $D_{s1}(2536)$ meson. We also perform a calculation of the branching fractions for the semileptonic decays of $B$ and $B_{s}$ mesons into final states containing orbitally excited charmed and charmed-strange mesons, which...

    In the phenomenological relativistic framework of the Dirac equation for spherical nuclei, we use different kinds of single-particle central potentials ({sigma}{sub S}+{sigma}{sub 0}) to investigate certain aspects of the spin and pseudospin (PS) symmetries. Neither the splitting of PS doublets (PSDs) nor the similarity of the radial parts of the small components (F/r) of the corresponding Dirac spinors have been found related with the magnitude of {sigma}{sub S}+{sigma}{sub 0}, in the sense predicted by several authors in the last decade. This conclusion is shown to be valid, in particular, for a potential of Coulomb type. We give a simple explanation for the strong correlation established in the relativistic calculations between the similarity of the radial parts of the big (small) components of the Dirac spinors of two spin (pseudospin) partners and the number of their nodes. The direct effects of the so-called PS symmetry-breaking term (and its singularity point) on the F functions of the PSDs are also analysed. (orig.)

    2014-04-01

    Full Text Available The observation of a scalar resonance at the Large Hadron Collider (LHC, compatible with perturbative electroweak symmetry breaking, reinforces the Standard Model (SM parameterisation of all subatomic data. The logarithmic evolution of the SM gauge and matter parameters suggests that this parameterisation remains viable up to the Planck scale, where gravitational effects are of comparable strength. String theory provides a perturbatively consistent scheme to explore how the parameters of the Standard Model may be determined from a theory of quantum gravity. The free fermionic heterotic string models provide concrete examples of exact string solutions that reproduce the spectrum of the Minimal Supersymmetric Standard Model. Contemporary studies entail the development of methods to classify large classes of models. This led to the discovery of exophobic heterotic-string vacua and the observation of spinor-vector duality, which provides an insight to the global structure of the space of (2,0 heterotic-string vacua. Future directions entail the study of the role of the massive string states in these models and their incorporation in cosmological scenarios. A complementary direction is the formulation of quantum gravity from the principle of manifest phase space duality and the equivalence postulate of quantum mechanics, which suggest that space is compact. The compactness of space, which implies intrinsic regularisation, may be tightly related to the intrinsic finite length scale, implied by string phenomenology.

    One of the most fundamental features of a black hole in general relativity is its event horizon: a boundary from which nothing can escape. There has been a recent surge of interest in the nature of these event horizons and their local neighbourhoods. In an attempt to resolve black hole information paradox(es), and more generally, to better understand the path towards quantum gravity, ‘firewalls’ have been proposed as an alternative to black hole event horizons. In this paper, we explore the phenomenological implications of black holes possessing a surface or ‘firewall’, and predict a potentially detectable signature of these firewalls in the form of a high energy astrophysical neutrino flux. We compute the spectrum of this neutrino flux in different models and show that it is a possible candidate for the source of the PeV neutrinos recently detected by IceCube. This opens up a new area of research, bridging the non-perturbative physics of quantum gravity with the observational black hole and high energy astrophysics.

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.

    The structure of relativistic radiation mediated shocks (RRMS) propagating into a cold electron-proton plasma is calculated and analyzed. A qualitative discussion of the physics of relativistic and non relativistic shocks, including order of magnitude estimates for the relevant temperature and length scales, is presented. Detailed numerical solutions are derived for shock Lorentz factors $\\Gamma_u$ in the range $6\\le\\Gamma_u\\le30$, using a novel iteration technique solving the hydrodynamics and radiation transport equations (the protons, electrons and positrons are argued to be coupled by collective plasma processes and are treated as a fluid).

    SURF and its extension SURFplus are reactive burn models aimed at shock initiation and propagation of detonation waves in high explosives. A distinctive feature of these models is that the burn rate depends on the lead shock pressure. A key part of the models is an algorithm to detect the lead shock. Typically, shock capturing hydro algorithms have small oscillations behind a shock.

    SURF and its extension SURFplus are reactive burn models aimed at shock initiation and propagation of detonation waves in high explosives. A distinctive feature of these models is that the burn rate depends on the lead shock pressure. A key part of the models is an algorithm to detect the lead shock. Typically, shock capturing hydro algorithms have small oscillations behind a shock. Here we investigate how well the shock detection algorithm works for a nearly steady propagating detonation wave in one-dimension using the Eulerian xRage code.

    2007-01-01

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

  16. Stroke rehabilitation and the phenomenological reconstitution of the self.

    Banja, John D

    2011-01-01

    This commentary will apply the notions of constitution and "phenomenological introspection" developed by phenomenology's founder Edmund Husserl to certain themes in Sharon Kaufman's 1988 essay, "Toward a Phenomenology of Boundaries in Medicine: Chronic Illness Experience in the Case of Stroke." The article will discuss how phenomenological analysis can provide important therapeutic insights about the lived experiences of stroke patients and their caregivers, especially as that experience is shaped in the immediate aftermath of a serious stroke. This article will also argue that phenomenology in and by itself is woefully inadequate for producing the kind of self-knowledge and political will needed to produce a socioeconomic environment that reasonably accommodates the needs of stroke patients. The article will end with a brief discussion of how an Eastern, particularly Buddhist, conception of the self is considerably more disability friendly than the one Westerners (phenomenologically) "constitute" and how the former's more realistic understanding of the trajectory of human functioning and its inevitable decline over a lifespan offers a superior platform for developing disability policy and care than its Western counterpart.

  17. Physics of Collisionless Shocks Space Plasma Shock Waves

    2013-01-01

    The present book provides a contemporary systematic treatment of shock waves in high-temperature collisionless plasmas as are encountered in near Earth space and in Astrophysics. It consists of two parts. Part I develops the complete theory of shocks in dilute hot plasmas under the assumption of absence of collisions among the charged particles when the interaction is mediated solely by the self-consistent electromagnetic fields. Such shocks are naturally magnetised implying that the magnetic field plays an important role in their evolution and dynamics. This part treats both subcritical shocks, which dissipate flow energy by generating anomalous resistance or viscosity, and supercritical shocks. The main emphasis is, however, on super-critical shocks where the anomalous dissipation is insufficient to retard the upstream flow. These shocks, depending on the direction of the upstream magnetic field, are distinguished as quasi-perpendicular and quasi-parallel shocks which exhibit different behaviours, reflecti...

    Novel low-energy defibrillation therapies are thought to be driven by virtual-electrodes (VEs), due to the interaction of applied monophasic electric shocks with fine-scale anatomical structures within the heart. Significant inter-species differences in the cardiac (micro)-anatomy exist, however, particularly with respect to the degree of endocardial trabeculations, which may underlie important differences in response to low-energy defibrillation protocols. Understanding the interaction of monophasic electric fields with the specific human micro-anatomy is therefore imperative in facilitating the translation and optimisation of these promising experimental therapies to the clinic. In this study, we sought to investigate how electric fields from implanted devices interact with the highly trabeculated human endocardial surface to better understand shock success in order to help optimise future clinical protocols. A bi-ventricular human computational model was constructed from high resolution (350 μm) ex-vivo MR data, including anatomically accurate endocardial structures. Monophasic shocks were applied between a basal right ventricular catheter and an exterior ground. Shocks of varying strengths were applied with both anodal [positive right ventricle (RV) electrode] and cathodal (negative RV electrode) polarities at different states of tissue refractoriness and during induced arrhythmias. Anodal shocks induced isolated positive VEs at the distal side of "detached" trabeculations, which rapidly spread into hyperpolarised tissue on the surrounding endocardial surfaces following the shock. Anodal shocks thus depolarised more tissue 10 ms after the shock than cathodal shocks where the propagation of activation from VEs induced on the proximal side of "detached" trabeculations was prevented due to refractory endocardium. Anodal shocks increased arrhythmia complexity more than cathodal shocks during failed anti-arrhythmia shocks. In conclusion, multiple detached

    Traumatic neurogenic shock is a rare but serious complication of spinal cord injury. It associates bradycardia and hypotension caused by a medullary trauma. It is life-threatening for the patient and it aggravates the neurological deficit. Strict immobilization and a quick assessment of the gravity of cord injury are necessary as soon as prehospital care has begun. Initial treatment requires vasopressors associated with fluid resuscitation. Steroids are not recommended. Early decompression is recommended for incomplete deficit seen in the first 6 hours. We relate the case of secondary spinal shock to a luxation C6/C7 treated in prehospital care.

    According to the data in the literature, the authors attempted to sum-up present attitudes on the value of corticoids in the treatment of septic shock. If their cardiovascular effects after a period of enthusiasm, are presently rather controversial, their cellular and sub-cellular actions, on the lysosomal membranes, capillary permeability and perhaps the intimate mechanisms of cellular oxygenation seem to be more real. However, the contra-indications which persist in the results of clinical works have resulted in the fact that the exact place of cortico-steroids in the therapeutic arsenal of septic shock still remains to be specified.

    As travel has become easier and more affordable, the number of people traveling has risen sharply. People travel for many and varied reasons, from the business person on an overseas assignment to backpackers seeking new and exotic destinations. Others may take up residence in different regions, states or countries for family, business or political reasons. Other people are fleeing religious or political persecution. Wherever they go and for whatever reason they go, people take their culture with them. Culture, like language, is acquired innately in early childhood and is then reinforced through formal and complex informal social education into adulthood. Culture provides a framework for interpersonal and social interactions. Therefore, the contact with a new culture is often not the exciting or pleasurable experience anticipated. When immersed in a different culture, people no longer know how to act when faced with disparate value systems. Contact with the unfamiliar culture can lead to anxiety, stress, mental illness and, in extreme cases, physical illness and suicide. "Culture shock" is a term coined by the anthropologist Oberg. It is the shock of the new. It implies that the experience of the new culture is an unpleasant surprise or shock, partly because it is unexpected and partly because it can lead to a negative evaluation of one's own culture. It is also known as cross-cultural adjustment, being that period of anxiety and confusion experienced when entering a new culture. It affects people intellectually, emotionally, behaviorally and physically and is characterized by symptoms of psychological distress. Culture shock affects both adults and children. In travelers or workers who have prolonged sojourns in foreign countries, culture shock may occur not only as they enter the new culture, but also may occur on their return to their original culture. Children may also experience readjustment problems after returning from leading sheltered lives in expatriate

  2. Characteristics of Weak Interplanetary Shocks and Shock-like Events

    Science.gov (United States)

    Balogh, A.; Gloag, J. M.

    The variation of magnetic and plasma parameters across the discontinuity of a colli- sionless shock wave are clearly understood and presented in MHD theory. The anal- ysis of 116 shock waves appearing on the Ulysses shock list in the period mid 1996 to the end of 1999 show that in the cases of the stronger shock waves, measured by the ratio of downstream to upstream magnetic field magnitudes, this MHD descrip- tion is adequate. However in the case of many of the weaker shocks there are events which are not clearly characterised in MHD terms and in these cases plasma param- eters are particularly difficult to interpret. To explore the issues associated with these very weak shocks further, a set of shock-like events is considered which have shock characteristics in the high frequency wave data measured by the plasma wave inves- tigation(URAP) but are not considered to be clearly shock waves purely considering magnetic and plasma data. These shock-like events are thought to extend the spectrum of interplanetary shocks at the very weakest end and possibly beyond what should be considered a collisionless shock wave.

    Curved shock theory is introduced and applied to calculate the flow behind concave shock waves. For sonic conditions, three characterizing types of flow are identified, based on the orientation of the sonic line, and it is shown that, depending on the ratio of shock curvatures, a continuously curving shock can exist with Type III flow, where the sonic line intercepts the reflected characteristics from the shock, thus preventing the formation of a reflected shock. The necessary shock curvature ratio for a Type III sonic point does not exist for a hyperbolic shock so that it will revert to Mach reflection for all Mach numbers. A demonstration is provided, by CFD calculations, at Mach 1.2 and 3.

    In the present study, we investigate the possible relationship of IP parameters of solar wind and interplanetary magnetic field with ground-based geomagnetic indices. To carry out the study, we take all the IP shock events listed by Proton Monitor onboard Solar and Heliospheric Observatory (SOHO) during 2005, and plot the time variations of all the IP parameters and geomagnetic parameters (±5 days), centered at the shock arrival time. Next, we obtain scatter plots of absolute values of solar wind parameters such as Vsw, Nsw and Interplanetary Magnetic Field (IMF) components Bx, By, Bz and total B with the values of geomagnetic parameters such as Dst, Kp indices, dayside Magnetopause (MP) distance and Cosmic-Ray Neutron Monitor count (CRNM). The scatter plots show that before the IP shock, the pattern is random with no clear relationship. Following the shock, a clear pattern emerges with a type of relationship being seen – clear for SHARP shocks and less clear for DIFFUSE shocks. A total of 10 shock events for 2005 have been studied. Typical examples of this behaviour are the shock events of January 21, 2005 and May 15, 2005. Our study suggests a definite correlation between changes in the solar wind and interplanetary magnetic field parameters and ground-based geomagnetic response. We are trying to obtain quantitative relationships between these for shock events of 2005.

The manuscript also identifies the limits of applicability of classical molecular dynamics based shock compression simulation for PVC. The mechanism of bond dissociation under shock loading and its progression is demonstrated in this manuscript using the density functional theory based molecular dynamics simulations. The rate of dissociation of different bonds at different shock velocities is also presented in this manuscript.

    The shock-tube problem has served as a popular test for numerical hydrodynamics codes. The development of relativistic hydrodynamics codes has created a need for a similar test problem in relativistic hydrodynamics. The analytical solution to the special relativistic shock-tube problem is presented here. The relativistic shock-jump conditions and rarefaction solution which make up the shock tube are derived. The Newtonian limit of the calculations is given throughout.

    The equations governing the motion of hypoelastic materials (and related models of non-Newtonian fluids) are not in conservation form. Hence there is no obvious formulation of Rankine-Hugoniot jump conditions across a shock. In this paper we demonstrate that a viscosity criterion can be used to obtain meaningful shock conditions. In particular, we discuss shocks of small amplitude. The shock conditions obtained will in general depend on the form of the viscosity term.

    We use STEREO data to study shocks driven by stream interactions and the waves associated with them. During the years of the extended solar minimum 2007-2010, stream interaction shocks have Mach numbers between 1.1-3.8 and {theta}{sub Bn}{approx}20-86 Degree-Sign . We find a variety of waves, including whistlers and low frequency fluctuations. Upstream whistler waves may be generated at the shock and upstream ultra low frequency (ULF) waves can be driven locally by ion instabilities. The downstream wave spectra can be formed by both, locally generated perturbations, and shock transmitted waves. We find that many quasiperpendicular shocks can be accompanied by ULF wave and ion foreshocks, which is in contrast to Earth's bow shock. Fluctuations downstream of quasi-parallel shocks tend to have larger amplitudes than waves downstream of quasi-perpendicular shocks. Proton foreshocks of shocks driven by stream interactions have extensions dr {<=}0.05 AU. This is smaller than foreshock extensions for ICME driven shocks. The difference in foreshock extensions is related to the fact that ICME driven shocks are formed closer to the Sun and therefore begin to accelerate particles very early in their existence, while stream interaction shocks form at {approx}1 AU and have been producing suprathermal particles for a shorter time.

    The 2008-2010 food crisis might have been a harbinger of fundamental climate-induced food crises with geopolitical implications. Heat-wave-induced yield losses in Russia and resulting export restrictions led to increases in market prices for wheat across the Middle East, likely contributing to the Arab Spring. With ongoing climate change, temperatures and temperature variability will rise, leading to higher uncertainty in yields for major nutritional crops. Here we investigate which countries are most vulnerable to teleconnected supply-shocks, i.e. where diets strongly rely on the import of wheat, maize, or rice, and where a large share of the population is living in poverty. We find that the Middle East is most sensitive to teleconnected supply shocks in wheat, Central America to supply shocks in maize, and Western Africa to supply shocks in rice. Weighing with poverty levels, Sub-Saharan Africa is most affected. Altogether, a simultaneous 10% reduction in exports of wheat, rice, and maize would reduce caloric intake of 55 million people living in poverty by about 5%. Export bans in major producing regions would put up to 200 million people below the poverty line at risk, 90% of which live in Sub-Saharan Africa. Our results suggest that a region-specific combination of national increases in agricultural productivity and diversification of trade partners and diets can effectively decrease future food security risks.

    Our present knowledge of the properties of the various planetary bow shocks is briefly reviewed. We do not follow the astronomical ordering of the planets. We rather distinguish between magnetised and unmagnetised planets which groups Mercury and Earth with the outer giant planets of the solar system, Mars and Moon in a separate group lacking magnetic fields and dense atmospheres, and Venus together with the comets as the atmospheric celestial objects exposed to the solar wind. Asteroids would, in this classification, fall into the group together with the Moon and should behave similarly though being much smaller. Extrasolar planets are not considered as we have only remote information about their behaviour. The presentation is brief in the sense that our in situ knowledge is rather sporadic yet, depending on just a countable number of bow shock crossings from which just some basic conclusions can be drawn about size, stationarity, shape and nature of the respective shock. The only bow shock of which we have ...

    The Hugoniot (4 - 30 GPa) and the isotherm (1 - 7 GPa) of nitrobenzene have been investigated by shock and static compression experiments. Nitrobenzene has the most basic structure of nitro aromatic compounds, which are widely used as energetic materials, but nitrobenzene has been considered not to explode in spite of the fact its calculated heat of detonation is similar to TNT, about 1 kcal/g. Explosive plane-wave generators and diamond anvil cell were used for shock and static compression, respectively. The obtained Hugoniot consists of two linear lines, and the kink exists around 10 GPa. The upper line agrees well with the Hugoniot of detonation products calculated by KHT code, so it is expected that nitrobenzene detonates in that area. Nitrobenzene solidifies under 1 GPa of static compression, and the isotherm of solid nitrobenzene was obtained by X-ray diffraction technique. Comparing the Hugoniot and the isotherm, nitrobenzene is in liquid phase under experimented shock condition. From the expected phase diagram, shocked nitrobenzene seems to remain metastable liquid in solid phase region on that diagram.

    2007-01-01

    Matched filtering is used to search for gravitational waves emitted by inspiralling compact binaries in data from ground-based interferometers. One of the key aspects of the detection process is the deployment of a set of templates, also called a template bank, to cover the astrophysically interesting region of the parameter space. In a companion paper, we described the template-bank algorithm used in the analysis of LIGO data to search for signals from non-spinning binaries made of neutron star and/or stellar-mass black holes; this template bank is based upon physical template families. In this paper, we describe the phenomenological template bank that was used to search for gravitational waves from non-spinning black hole binaries (from stellar mass formation) in the second, third and fourth LIGO science runs. We briefly explain the design of the bank, whose templates are based on a phenomenological detection template family. We show that this template bank gives matches greater than 95% with the physical t...

  19. [The psychological dynamics of Kurt Lewin. The problem of the relation between mechanics and phenomenology].

    2005-01-01

    By reviewing especially Lewin's researches from his German period - which are important insofar as they exhibit the epistemological grounds of his whole work, as well as his fundamental insights into the "structure of mind" - the Author points out a series of difficulties inherent in Lewin's original approach. Such difficulties also explain why Lewin's grandiose program to develop a scientific psychology, more mathematico-galilaeiano, was after his time abandoned. Indeed, if on the one hand a rereading of Lewin's epistemology reveals the unexpected debt he pays to the mechanical model of thought, yet, on the other hand, a careful analysis of his notion of "field," otherwise fruitful, shows that he can neither consistently exploit his phenomenological view of the field as a "space of life," nor adequately deal with the human subject by the mere experimental method. As a matter of fact, the brave effort to join the two patterns together - the phenomenological and the experimental-objectivistic-mathematical one - produces a basic ambiguity, owing not so much to Lewin's limitations as to the epochal clash between two patterns that are actual gnoseological and methodological archetypes. Nevertheless, some weakness in Lewin's "dynamic" approach does not seem by itself to prejudge his later social psychology; rather, also in the light of recent historiography, the question of the link between these different moments of his work should be reconsidered.

  1. Phenomenological sizes of confinement regions in baryons

    Energy Technology Data Exchange (ETDEWEB)

    Brown, G.E.; Klimt, S.; Weise, W.; Rho, M.

    1988-10-01

    Standard order of magnitude estimates from QCD indicate that the radius of the quark-gluon core in the nucleon is ..lambda../sup -1//sub QCD/ > or approx. 1 fm. However, in work with the chiral bag model, we have found that the effective confinement size for low energy reactions can be as small as approx. = 1/2 fm or smaller. This shrinking of the effective confinement size has been attributed to the pressure of the pion cloud surrounding the quark core. The concept of confinement size is evidently subtle in light-quark systems, due to the chiral vacuum structure. This is indicated by the 'Cheshire Cat' phenomenon, in which physical observables tend to be insensitive to the bag radius R. We suggest that when strange quarks are present, a qualitative change occurs in the Cheshire Cat picture; in particular, we propose that strangeness provides an obstruction to this picture. We present a phenomenological indication that when strange quarks are present, the bag radius R is frozen at a value substantially larger than 0.5 fm by as much as a factor of two. Roughly speaking, the Cheshire Cat picture emerges from a near cancellation between repulsive quark kinetic and attractive pion-cloud energies in the case of the nucleon. In the ..lambda.. and ..sigma.. particles, however, replacement of one up or down quark by a strange quark removes part of the attraction from the coupling of the quarks to the pion cloud. This upsets the balance needed for the Cheshire Cat phenomenon and makes larger strange baryons more favorable energetically than the 0.5 fm ones appropriate for pure u- and d-systems. We find that magnetic moments of strange baryons favor a bag radius R approx. = 1.1 fm. We find that the excited states of the ..lambda..-hyperons favor similarly large bag radii. Somewhat less convincingly, due to perturbative effects - the bag radius appropriate to the ..delta..(1232) lies intermediate between that of the nucleon and of the stran

  2. In situ local shock speed and transit shock speed

    Directory of Open Access Journals (Sweden)

    S. Watari

    Full Text Available A useful index for estimating the transit speeds was derived by analyzing interplanetary shock observations. This index is the ratio of the in situ local shock speed and the transit speed; it is 0.6–0.9 for most observed shocks. The local shock speed and the transit speed calculated for the results of the magnetohydrodynamic simulation show good agreement with the observations. The relation expressed by the index is well explained by a simplified propagation model assuming a blast wave. For several shocks the ratio is approximately 1.2, implying that these shocks accelerated during propagation in slow-speed solar wind. This ratio is similar to that for the background solar wind acceleration.

    2017-05-01

    Wave-driven outflows and non-disruptive explosions have been implicated in pre-supernova outbursts, supernova impostors, luminous blue variable eruptions, and some narrow-line and superluminous supernovae. To model these events, we investigate the dynamics of stars set in motion by strong acoustic pulses and wave trains, focusing on nonlinear wave propagation, shock formation, and an early phase of the development of a weak shock. We identify the shock formation radius, showing that a heuristic estimate based on crossing characteristics matches an exact expansion around the wave front and verifying both with numerical experiments. Our general analytical condition for shock formation applies to one-dimensional motions within any static environment, including both eruptions and implosions. We also consider the early phase of shock energy dissipation. We find that waves of super-Eddington acoustic luminosity always create shocks, rather than damping by radiative diffusion. Therefore, shock formation is integral to super-Eddington outbursts.

    Sheets-Johnstone, Maxine

    2015-12-01

    This paper first clarifies phenomenology in ways essential to demonstrating its basic concern with Nature and its recognition of individual and cultural differences as well as commonalities. It furthermore clarifies phenomenological methodology in ways essential to understanding the methodology itself, its purpose, and its consequences. These clarifications show how phenomenology, by hewing to the dynamic realities of life itself and experiences of life itself, counters reductive thinking and "embodiments" of one kind and another. On the basis of these clarifications, the paper then turns to detailing conceptual complementarities between phenomenology and the life sciences, particularly highlighting studies in coordination dynamics. In doing so, it brings to light fundamental relationships such as those between mind and motion and between intrinsic dynamics and primal animation. It furthermore highlights the common concern with origins in both phenomenology and evolutionary biology: the history of how what is present is related to its inception in the past and to its transformations from past to present.

  8. Rigour in phenomenological research: reflections of a novice nurse researcher.

    Pereira, Helder Rocha

    2012-01-01

    This paper is intended to explore conflicts and doubts that novice researchers face when using phenomenological research methods, especially with regard to methodological rigour. There is an increasing interest in different qualitative approaches. The best way to evaluate the quality of qualitative studies has been debated intensively. The great theoretical and methodological diversity of qualitative approaches suggests that a single set of criteria may not be appropriate for all types of research. This is a methodological paper that discusses a personal experience of addressing rigour in a phenomenological study, supported by literature on the topic. Generic qualitative criteria may not be the most adequate to ensure rigour in phenomenological research. The different poles of discussion about the best way to ensure validity of phenomenological research puzzle novice nurse researchers. Focusing on integrative validity that addresses experiential and methodological concerns ensures that researchers will respect the philosophical assumptions underlying a method and allows them to recognise study soundness in the findings and the research process. Phenomenological research must demonstrate methodological congruence and provide meaningful results about lived experiences in a balanced way. Novice researchers need support to understand the articulation between philosophical and methodological foundations that guide the methods they use.

  9. A phenomenological investigation of science center exhibition developers' expertise development

    Young, Denise L.

    The purpose of this study was to examine the exhibition developer role in the context of United States (U.S.) science centers, and more specifically, to investigate the way science center exhibition developers build their professional expertise. This research investigated how successfully practicing exhibition developers described their current practices, how they learned to be exhibition developers, and what factors were the most important to the developers in building their professional expertise. Qualitative data was gathered from 10 currently practicing exhibition developers from three science centers: the Exploratorium, San Francisco, California; the Field Museum, Chicago, Illinois; and the Science Museum of Minnesota, St. Paul, Minnesota. In-depth, semistructured interviews were used to collect the data. The study embraced aspects of the phenomenological tradition and sought to derive a holistic understanding of the position and how expertise was built for it. The data were methodically coded and organized into themes prior to analysis. The data analysis found that the position consisted of numerous and varied activities, but the developers' primary roles were advocating for the visitor, storytelling, and mediating information and ideas. They conducted these activities in the context of a team and relied on an established exhibition planning process to guide their work. Developers described a process of learning exhibition development that was experiential in nature. Learning through daily practice was key, though they also consulted with mentors and relied on visitor studies to gauge the effectiveness of their work. They were adept at integrating prior knowledge gained from many aspects of their lives into their practice. The developers described several internal factors that contributed to their expertise development including the desire to help others, a natural curiosity about the world, a commitment to learning, and the ability to accept critique. They

    The study of psycho-emotional reactions associated with chronic neuropathies, is an important factor of the integrated solution to the problem of treatment and prevention of disorders of the peripheral nervous system. The aim of the research is to study clinical psychopathological phenomenology and personality characteristics of patients suffering from chronic neuropathies. We examined 115 patients with chronic neuropathies in comparison with 60 healthy persons using a clinical conversation method, shortened multivariable personality questionnaire, The Zung Self-Rating Depression Scale, Spilberger's scale of trait and state anxiety and Symptom Check List-90-Revised questionnaire. Patients with chronic neuropathies are characterized by multiple complaints from the psycho-emotional sphere, the most common of which are depressed mood (72.2%), fatigue (76.5%) and sleep disorders (77.4%). Elevated levels of somatization (2,35 ± 0,66 points), interpersonal sensitivity (1,83 ± 0,80 points), depression (2,82 ± 1,05 points), anxiety (2,08 ± 1, 28 points) were revealed in patients. The level of depression on the The Zung Self-Rating Depression Scale in patients corresponded to mild depression of situational or neurotic genesis (54,45 ± 9,93 points), and trait and state anxiety to an increased level (respectively 45,17 ± 11,19 points and 45,14 ± 9,89 points). Specific personality traits in the form of persistent depressive tendencies combined with hypochondriacal symptoms, an increase in trait and state anxiety, decreased general reactivity and manifestations of chronic fatigue and exhaustion correspond to somatic predisposition and provide ground to consider them as signs of persistent neuroticism with hypochondriacal personality development and accentuation on hypothymic (dysthymic) type. The study revealed a wide range of psychopathological phenomena of a polymorphic character. The main psychopathological construct of unfavourable changes in the psycho

    globally women receive HIV testing in pregnancy; however, limited information is available on their experiences of this potentially life-changing event. This study aims to explore women's experiences of receiving a positive HIV test result following antenatal screening. a qualitative, phenomenological approach. two public National Health Service (NHS) hospitals and HIV support organisations. a purposive sampling strategy was used. Thirteen black African women with a positive HIV result, in England, participated. data were collected using in-depth semi-structured interviews. An interpretive phenomenological approach to data analysis was used. the emergent phenomenon was transition and transformation of 'being,' as women accepted HIV as part of their lives. Paired themes support the phenomenon: shock and disbelief; anger and turmoil; stigma and confidentiality issues; acceptance and resilience. Women had extreme reactions to their positive HIV diagnosis, compounded by the cultural belief that they would die. Initial disbelief of the unexpected result developed into sadness at the loss of their old self. Turmoil was evident, as women considered termination of pregnancy, self-harm and suicide. Women felt isolated from others and relationship breakdowns often occurred. Most reported the pervasiveness of stigma, and how this was managed alongside living with HIV. Coping strategies included keeping HIV 'secret' and making their child(ren) the prime focus of life. Growing resilience was apparent with time. this study gives midwives unique understanding of the complexities and major implications for women who tested positive for HIV. Women's experiences resonated with processes of bereavement, providing useful insight into a transitional and transformational period, during which appropriate support can be targeted. midwives are crucial in improving the experience of women when they test HIV positive and to do this they need to be appropriately trained. Midwives need to

    Menarche is a significant physical and emotional experience for adolescent girls, especially in certain cultures, where it is viewed as a rite of passage, affecting the meaning of lived experiences. The purpose of the study was to explore the menarche experience among Jordanian adolescent girls when they reach menarche. Interpretive phenomenological analysis. Az-Zarqa City, Jordan. A homogenous sample of 7 Jordanian girls, ages 12-14 years, who had their first menstruation within the past 6 months. Participants were asked to narrate their experiences through journal writing; their reports to be used for interpretive phenomenological analyses by 2 independent researchers, to ensure the findings' trustworthiness. Three major themes emerged as: (1) menstruation as a forbidden topic; (2) keeping the "topic" to oneself; and (3) no more secrets. Each theme was characterized according to distinct sets of emotions and knowledge-seeking patterns because Jordanian culture and Islamic teachings had greatly influenced the girls' experience of menarche. Menarche was considered a social taboo; not to be openly discussed. At the first signs of menarche, participants were shocked, scared, confused, and anxious. They had limited information and support from their family or school system. Therefore, they relied on self-perceptions about menarche, and viewed the experience of menstruation with profound negative emotions. Participants hesitated to share their experiences with their mothers and close friends. They felt alone and experienced their emotional turmoil in isolation and without support. Jordanian adolescent girls need formal health education to understand and manage the reproductive changes that occur in their bodies.

    The results from the cubic polynomial (CP) formula of the square of the angular velocity and the nuclear moments of inertia are compared with those from the variable moment of inertia (VMI) model and the available experimental information on transition energies for yrast line in even-even nuclei. The evaluated model parameters lead to an excellent fit for all energy levels ( I approx 24). The calculated critical spin for backbending in the zeta - omega sup 2 plot is found to be in agreement with the experimental data. (author)

    Curved shock theory is used to show that the flow behind attached shocks on doubly curved wedges can have either positive or negative post-shock pressure gradients depending on the freestream Mach number, the wedge angle and the two wedge curvatures. Given enough wedge length, the flow near the leading edge can choke to force the shock to detach from the wedge. This local choking can preempt both the maximum deflection and the sonic criteria for shock detachment. Analytical predictions for detachment by local choking are supported by CFD results.

  16. What is an organ? Heidegger and the phenomenology of organ transplantation.

    Science.gov (United States)

    Svenaeus, Fredrik

    2010-06-01

    This paper investigates the question of what an organ is from a phenomenological perspective. Proceeding from the phenomenology of being-in-the-world developed by Heidegger in Being and Time and subsequent works, it compares the being of the organ with the being of the tool. It attempts to display similarities and differences between the embodied nature of the organs and the way tools of the world are handled. It explicates the way tools belong to the totalities of things of the world that are ready to use and the way organs belong to the totality of a bodily being able to be in this very world. In so doing, the paper argues that while the organ is in some respects similar to a bodily tool, this tool is nonetheless different from the tools of the world in being tied to the organism as a whole, which offers the founding ground of the being of the person. However, from a phenomenological point of view, the line between organs and tools cannot simply be drawn by determining what is inside and outside the physiological borders of the organism. We have, from the beginning of history, integrated technological devices (tools) in our being-in-the-world in ways that make them parts of ourselves rather than parts of the world (more organ- than tool-like), and also, more recently, have started to make our organs more tool-like by visualising, moving, manipulating, and controlling them through medical technology. In this paper, Heidegger's analysis of organ, tool, and world-making is confronted with this development brought about by contemporary medical technology. It is argued that this development has, to a large extent, changed the phenomenology of the organ in making our bodies more similar to machines with parts that have certain functions and that can be exchanged. This development harbours the threat of instrumentalising our bodily being but also the possibility of curing or alleviating suffering brought about by diseases which disturb and destroy the normal functioning

    We derive fast forward interplanetary (IP) shock speeds and impact angles to study the geoeffectivness of 461 IP shocks that occurred from January 1995 to December 2013 using ACE and WIND spacecraft data. The geomagnetic activity is inferred from the SuperMAG project data. SuperMAG is a large chain which employs more than 300 ground stations to compute enhanced versions of the traditional geomagnetic indices. The SuperMAG auroral electroject SME index, an enhanced version of the traditional AE index, is used as an auroral power (AP) indicator. AP intensity jumps triggered by shock impacts are correlated with both shock speed and impact angle. It is found that high AP intensity events typically occur when high speed IP shocks impact the Earths magnetosphere with the shock normal almost parallel to the Sun-Earth line. This result suggests that symmetric and strong magnetospheric compression leads to favorable conditions for intense auroral power release, as shown previously by simulations and observations.

  19. A Shocking Surprise in Stephan's Quintet

    Science.gov (United States)

    2006-01-01

    This false-color composite image of the Stephan's Quintet galaxy cluster clearly shows one of the largest shock waves ever seen (green arc). The wave was produced by one galaxy falling toward another at speeds of more than one million miles per hour. The image is made up of data from NASA's Spitzer Space Telescope and a ground-based telescope in Spain. Four of the five galaxies in this picture are involved in a violent collision, which has already stripped most of the hydrogen gas from the interiors of the galaxies. The centers of the galaxies appear as bright yellow-pink knots inside a blue haze of stars, and the galaxy producing all the turmoil, NGC7318b, is the left of two small bright regions in the middle right of the image. One galaxy, the large spiral at the bottom left of the image, is a foreground object and is not associated with the cluster. The titanic shock wave, larger than our own Milky Way galaxy, was detected by the ground-based telescope using visible-light wavelengths. It consists of hot hydrogen gas. As NGC7318b collides with gas spread throughout the cluster, atoms of hydrogen are heated in the shock wave, producing the green glow. Spitzer pointed its infrared spectrograph at the peak of this shock wave (middle of green glow) to learn more about its inner workings. This instrument breaks light apart into its basic components. Data from the instrument are referred to as spectra and are displayed as curving lines that indicate the amount of light coming at each specific wavelength. The Spitzer spectrum showed a strong infrared signature for incredibly turbulent gas made up of hydrogen molecules. This gas is caused when atoms of hydrogen rapidly pair-up to form molecules in the wake of the shock wave. Molecular hydrogen, unlike atomic hydrogen, gives off most of its energy through vibrations that emit in the infrared. This highly disturbed gas is the most turbulent molecular hydrogen ever seen. Astronomers were surprised not only by the turbulence

    Global phenomenological GDP08 and microscopic helium-3 optical model potentials have been recently derived. We evaluate these two potential sets by comparing the elastic scattering data of 25 MeV 3He on 16O, 18O, 19F, 23Na, 24Mg, 25Mg, 26Mg, 27Al, 28Si, 30Si, 31P, 32S, 34S, 35Cl, 37Cl, and 39K isotopes. Using the deuteron angular distributions calculated with the distorted wave Born approximation model, we extract the ground-state proton spectroscopic factors from (3He, d) reactions on the same set of nuclei. The extracted proton spectroscopic factors are compared with the large-basis shell-model calculations.

    Full Text Available By taking care of cancer patients in their process of end of life, nursing experience situations of suffering before the anguish of others. This study aimed to understand the meaning and significance attributed by the nurses from the palliative care cancer hospital. This is a phenomenological research, grounded in Heidegger’s thinking, performed with 13 nurses, who work at Oncology hospitalward, through semi-structured interviews, which were analyzed according to the steps recommended by Josgrilberg. From understanding the statementsof the subjects, two ontological themesemerged: Feeling satisfaction and love in the care offered and Feeling anger and inabilitytowards terminally ill patients.We inferred that working in Oncology Ward is something rewarding for these professionals, but it entails physical and mental suffering, from feeling helpless before the death-dying process. Thus, we showedthat nursing professionals need to be recognized as human beings and as such, also deserving of care.

    Parry, Jonathan

    2003-01-01

    This paper attempts to answer the research question, "how do senior executives in my organisation make sense of their professional life?" Having reviewed the sensemaking literature, in particular that of the pre-eminent author in this field, Karl E. Weick, I adopt a phenomenological, interpretist orientation which relies on an ideographic, inductive generation of theory. I situate myself, both as researcher and chief executive of the organisation studied, in the narrative of sensemaking. Using semi-structured interviews and a combination of grounded theory and template analysis to generate categories, seven themes of sensemaking are tentatively produced which are then compared with Weick's characteristics. The methodological approach is then reflected on, criticised and alternative methodologies are briefly considered. The conclusion reached is that the themes generated by the research may have relevance for sensemaking processes, but that the production of formal theory through social research is problematic.

  3. Dependence of the aftershock flow on the main shock magnitude

    2017-01-01

    Previously, we predicted and then observed in practice the property of aftershocks which consists in the statistically regular clustering of events in time during the first hours after the main shock. The characteristic quasi-period of clustering is three hours. This property is associated with the cumulative action of the surface waves converging to the epicenter, whereas the quasi-period is mainly determined by the time delay of the round-the-world seismic echo. The quasi-period varies from case to case. In the attempt to find the cause of this variability, we have statistically explored the probable dependence of quasi-period on the magnitude of the main shock. In this paper, we present the corresponding result of analyzing global seismicity from the USGS/NEIC earthquake catalog. We succeeded in finding a significant reduction in the quasiperiod of the strong earthquakes clustering with growth in the magnitude of the main shock. We suggest the interpretation of this regularity from the standpoint of the phenomenological theory of explosive instability. It is noted that the phenomenon of explosive instability is fairly common in the geophysical media. The examples of explosive instability in the radiation belt and magnetospheric tail are presented. The search for the parallels in the evolution of explosive instability in the lithosphere and magnetosphere of the Earth will enrich both the physics of the earthquakes and physics of the magnetospheric pulsations.

    1988-01-01

    The effect produced by shock loading (to peak pressures of 12 and 24) on deformed synthetic quartz containing a dislocation and abundant bubbles and small inclusions was investigated, and the relationships between preexisting dislocation density shock lamellae in the target material were examined. The resultant material was found to be inhomogeneously deformed and extremely fractured. Results of TEM examinations indicate that no change in dislocation density was caused by shock loading except in regions containing shock lamellae, where the dislocation density was lowered. The shock-induced defects tend to nucleate on and be controlled by preexisting stress concentrators; shock lamellae, glassy veins, and most curviplanar defects form in tension, presumably during release. An extremely mobile silica fluid is formed and injected into fractures during release, which forcibly removes crystalline fragments from vein walls. It is concluded that shock deformation in quartz is dominated by fracture and melting.

    This volume of the Shock Wave Science and Technology Reference Library is concerned with the interplay between bubble dynamics and shock waves. It is divided into four parts containing twelve chapters written by eminent scientists. Topics discussed include shock wave emission by laser generated bubbles (W Lauterborn, A Vogel), pulsating bubbles near boundaries (DM Leppinen, QX Wang, JR Blake), interaction of shock waves with bubble clouds (CD Ohl, SW Ohl), shock propagation in polydispersed bubbly liquids by model equations (K Ando, T Colonius, CE Brennen.

  6. Cosmic Ray Spectrum in Supernova Remnant Shocks

    CERN Document Server

    Kang, Hyesung

    2010-01-01

    We perform kinetic simulations of diffusive shock acceleration (DSA) in Type Ia supernova remnants (SNRs) expanding into a uniform interstellar medium (ISM). Bohm-like diffusion assumed, and simple models for Alfvenic drift and dissipation are adopted. Phenomenological models for thermal leakage injection are considered as well. We find that the preshock gas temperature is the primary parameter that governs the cosmic ray (CR) acceleration efficiency and energy spectrum, while the CR injection rate is a secondary parameter. For SNRs in the warm ISM, if the injection fraction is larger than 10^{-4}, the DSA is efficient enough to convert more than 20 % of the SN explosion energy into CRs and the accelerated CR spectrum exhibits a concave curvature flattening to E^{-1.6}. Such a flat source spectrum near the knee energy, however, may not be reconciled with the CR spectrum observed at Earth. On the other hand, SNRs in the hot ISM, with an injection fraction smaller than 10^{-4}, are inefficient accelerators with...

    We study the time evolution of 2-point functions and entanglement entropy in strongly anisotropic, inhomogeneous and time-dependent N=4 super Yang-Mills theory in the large N and large 't Hooft coupling limit using AdS/CFT. On the gravity side this amounts to calculating the length of geodesics and area of extremal surfaces in the dynamical background of two colliding gravitational shockwaves, which we do numerically. We discriminate between three classes of initial conditions corresponding to wide, intermediate and narrow shocks, and show that they exhibit different phenomenology with respect to the nonlocal observables that we determine. Our results permit to use (holographic) entanglement entropy as an order parameter to distinguish between the two phases of the cross-over from the transparency to the full-stopping scenario in dynamical Yang-Mills plasma formation, which is frequently used as a toy model for heavy ion collisions. The time evolution of entanglement entropy allows to discern four regimes: hi...

  8. Vantage perspective during encoding: The effects on phenomenological memory characteristics.

    Mooren, Nora; Krans, Julie; Näring, Gérard W B; Moulds, Michelle L; van Minnen, Agnes

    2016-05-01

    The vantage perspective from which a memory is retrieved influences the memory's emotional impact, intrusiveness, and phenomenological characteristics. This study tested whether similar effects are observed when participants were instructed to imagine the events from a specific perspective. Fifty student participants listened to a verbal report of car-accidents and visualized the scenery from either a field or observer perspective. There were no between-condition differences in emotionality of memories and the number of intrusions, but imagery experienced from a relative observer perspective was rated as less self-relevant. In contrast to earlier studies on memory retrieval, vantage perspective influenced phenomenological memory characteristics of the memory representation such as sensory details, and ratings of vividness and distancing of the memory. However, vantage perspective is most likely not a stable phenomenological characteristic itself. Implications and suggestions for future research are discussed.

  9. Phenomenology and Sociological Research: The Constitution of “Friendship”

    Directory of Open Access Journals (Sweden)

    Jochen Dreher

    2016-01-01

    Full Text Available This analysis combines phenomenological and sociological research for an investigation of the social relationship of “friendship”. From a phenomenological perspective, it focuses on the epistemological basis, on the subjective constitution of the phenomenon of “friendship”. The social construction of friendship however, is described from a sociological research perspective with reference to concrete empirical expressions of this specific social relationship. The key for the reflections on friendship is the adaptation of Edmund Husserl’s method of phenomenological reduction for the analysis of social phenomena, based on the argumentations of Alfred Schutz and Aron Gurwitsch. This leads to the assumption that friendship is symbolically constituted with reference to everyday transcendent ideas which substantially define the specific expression of this social relationship.

    We are interested in the kind of knowledge that is particularly relevant to caring practice and the way in which qualitative research findings can serve such knowledge. As phenomenological researchers we have been engaged with the question of how findings from such research can be re-presented and expressed more aesthetically. Such a movement towards a more aesthetic phenomenology may serve the communicative concern to express phenomena relevant to caring practice in ways that appeal to the 'head, hand and heart'. The paper first offers some thoughts about the complex kind of knowledge relevant to caring that is not only technical or propositional, but actionable and aesthetically moving as well. We call this kind of knowledge 'embodied relational understanding'. Further, the paper outlines the development of one way of serving a more aesthetic phenomenology whereby research findings can be faithfully and evocatively translated into more empathically impactful expressions. We call this process 'embodied interpretation'. It is guided by an epistemological framework grounded in the philosophies of Gadamer and Gendlin. We finally illustrate the process with reference to the experience of living after Stroke, and consider the value of this translational process for nursing education and practice.

  11. Simulations of Relativistic Collisionless Shocks: Shock Structure and Particle Acceleration

    2006-04-10

    We discuss 3D simulations of relativistic collisionless shocks in electron-positron pair plasmas using the particle-in-cell (PIC) method. The shock structure is mainly controlled by the shock's magnetization (''sigma'' parameter). We demonstrate how the structure of the shock varies as a function of sigma for perpendicular shocks. At low magnetizations the shock is mediated mainly by the Weibel instability which generates transient magnetic fields that can exceed the initial field. At larger magnetizations the shock is dominated by magnetic reflections. We demonstrate where the transition occurs and argue that it is impossible to have very low magnetization collisionless shocks in nature (in more than one spatial dimension). We further discuss the acceleration properties of these shocks, and show that higher magnetization perpendicular shocks do not efficiently accelerate nonthermal particles in 3D. Among other astrophysical applications, this may pose a restriction on the structure and composition of gamma-ray bursts and pulsar wind outflows.

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

  13. About the Stimmung. Biranism and phenomenology

    Directory of Open Access Journals (Sweden)

    Umbelino, Luís António

    2009-04-01

    Full Text Available M. Richir, in recent works, showed the importance of a phenomenological analysis of the complex relations between “phantasie”, “imagination” and “afectivité” to the deciphering of our too much human nature. The terra incognita that can be seen from that conceptual crossroad is difficult to analyse and poses a challenge: to understand that we can not “measure” our “human condition” without taking into account the imaginative and affective dimensions, the boundaries of reason, the shores of the symbolic institution, the savage non perceptible presence of the Stimmung. In this particular context it is not, in our view, a detail the reference made by Richir to Maine de Biran. The phenomenologist believes Biran to be the philosopher that “better then anyone else, and much before Heidegger”, understood and more rigorously analysed the singular characteristics of that terra incognita (that “lost continent” as Biran puts it of the Stimmung, of the affective tonalities, variations and eruptions. This paper aims to underlain the main points of Richir’s positions on this subject, but also, and most of all, to meditate on that contribution made by Maine de Biran to the understanding of the always bizarre tonality that bathes the world when it appears to us with its Jemeiningkeit.Marc Richir ha mostrado en obras recientes la importancia de un análisis fenomenológico de las relaciones complejas entre fantasía, imaginación y afectividad, a fin de descifrar nuestra “demasiado humana” naturaleza.

    Purpose Febrile status epilepticus (FSE) has been associated with hippocampal injury and subsequent hipppocampal sclerosis (HS) and temporal lobe epilepsy. The FEBSTAT study was designed to prospectively examine the association between prolonged febrile seizures and development of HS and associated temporal lobe epilepsy, one of the most controversial issues in epilepsy. We report on the baseline phenomenology of the final cohorts as well as detailed aims and methodology. Methods The “Consequences of Prolonged Febrile Seizures in Childhood” (FEBSTAT) study is a prospective, multicenter study. Enrolled are children, aged 1 month to 6 years, presenting with a febrile seizure lasting 30 minutes or more based upon ambulance, emergency department, and hospital records, and parental interview. At baseline, procedures included an MRI and EEG done within 72 hours of FSE, and a detailed history and neurological examination. Baseline development and behavior are assessed at one month. The baseline assessment is repeated, with age- appropriate developmental testing at one and five years after enrollment as well as at the development of epilepsy and one year after that. Telephone calls every three months document further seizures. Two other groups of children are included: a ‘control’ group consisting of children with a first febrile seizure ascertained at Columbia University and with almost identical baseline and one year follow-up examinations and a pilot cohort of FSE from Duke University. Key findings The FEBSTAT cohort consists of 199 children with a median age at baseline of 16.0 months (Interquartile range (IQR)=12.0–24.0) and a median duration of FSE of 70.0 minutes (IQR=47.0–110.0). Seizures were continuous in 57.3% and behaviorally intermittent (without recovery in between) in 31.2%; most were partial (4;2.0%) or secondary generalized (65.8%), and almost all (98.0%) culminated in a generalized tonic clonic seizure. Of the 199 children, 86.4% had normal

  15. Desalination shocks in microstructures

    Mani, Ali

    2011-01-01

    Salt transport in bulk electrolytes is limited by diffusion and convection, but in microstructures with charged surfaces (e.g. microfluidic devices, porous media, soils, or biological tissues) surface conduction and electro-osmotic flow also contribute to ionic fluxes. For small applied voltages, these effects lead to well known linear electrokinetic phenomena. In this paper, we predict some surprising nonlinear dynamics that can result from the competition between bulk and interfacial transport at higher voltages. When counter-ions are selectively removed by a membrane or electrode, a "desalination shock" can propagate through the microstructure, leaving in its wake an ultrapure solution, nearly devoid of co-ions and colloidal impurities. We elucidate the basic physics of desalination shocks and develop a mathematical theory of their existence, structure, and stability, allowing for slow variations in surface charge or channel geometry. Via asymptotic approximations and similarity solutions, we show that des...

  17. SUPERDIFFUSIVE SHOCK ACCELERATION

    The theory of diffusive shock acceleration is extended to the case of superdiffusive transport, i.e., when the mean square deviation grows proportionally to t{sup {alpha}}, with {alpha} > 1. Superdiffusion can be described by a statistical process called Levy random walk, in which the propagator is not a Gaussian but it exhibits power-law tails. By using the propagator appropriate for Levy random walk, it is found that the indices of energy spectra of particles are harder than those obtained where a normal diffusion is envisaged, with the spectral index decreasing with the increase of {alpha}. A new scaling for the acceleration time is also found, allowing substantially shorter times than in the case of normal diffusion. Within this framework we can explain a number of observations of flat spectra in various astrophysical and heliospheric contexts, for instance, for the Crab Nebula and the termination shock of the solar wind.

    Directory of Open Access Journals (Sweden)

    Ingrid Richardson

    2005-01-01

    Full Text Available Today’s handheld devices are becoming increasingly multifunctional, portable and interactive technospaces which enfold (and unfold an assortment of media forms. This transformation requires a critical approach that considers mobile media as more than telecommunications tools, but also as hybrid new media interfaces. This article presents some initial thoughts pre-empting a larger research project on the phenomenology of mobile media. From a phenomenological perspective, each body-tool relation induces its own technosoma, or specific ways of ‘being-with-equipment’ in a Heideggerian sense; in this conceptual framework, I explore some of the medium specific and intercorporeal effects of the mobile phone.

  1. Shock breakout theory

    CERN Document Server

    Waxman, Eli

    2016-01-01

    The earliest supernova (SN) emission is produced when the optical depth of the plasma lying ahead of the shock, which ejects the envelope, drops below c/v, where v is the shock velocity. This "breakout" may occur when the shock reaches the edge of the star, producing a bright X-ray/UV flash on time scales of seconds to a fraction of an hour, followed by UV/optical "cooling" emission from the expanding cooling envelope on a day time-scale. If the optical depth of circumstellar material (CSM) ejected from the progenitor star prior to the explosion is larger than c/v, the breakout will take place at larger radii, within the CSM, extending its duration to days time scale. The properties of the early, breakout and cooling, emission carry unique signatures of the structure of the progenitor star (e.g. its radius and surface composition) and of its mass-loss history. The recent progress of wide-field transient surveys enable SN detections on a day time scale, and are being used to set unique constraints on the proge...

  2. Characterization of shocked beryllium

    Directory of Open Access Journals (Sweden)

    Papin P.A.

    2012-08-01

    Full Text Available While numerous studies have investigated the low-strain-rate constitutive response of beryllium, the combined influence of high strain rate and temperature on the mechanical behavior and microstructure of beryllium has received limited attention over the last 40 years. In the current work, high strain rate tests were conducted using both explosive drive and a gas gun to accelerate the material. Prior studies have focused on tensile loading behavior, or limited conditions of dynamic strain rate and/or temperature. Two constitutive strength (plasticity models, the Preston-Tonks-Wallace (PTW and Mechanical Threshold Stress (MTS models, were calibrated using common quasi-static and Hopkinson bar data. However, simulations with the two models give noticeably different results when compared with the measured experimental wave profiles. The experimental results indicate that, even if fractured by the initial shock loading, the Be remains sufficiently intact to support a shear stress following partial release and subsequent shock re-loading. Additional “arrested” drive shots were designed and tested to minimize the reflected tensile pulse in the sample. These tests were done to both validate the model and to put large shock induced compressive loads into the beryllium sample.

    Using modern high-energy-density facilities it is straightforward to produce radiative shock waves in which the transfer of energy by radiation controls the hydrodynamic structure of the system. Some of these experiments use shock tubes. This paper discusses such experiments, with an emphasis on the simple physical relations that determine the primary features of such shocks and on the details and impact of radiative energy transfer in such systems. Notable aspects include the creation of high-density shocked layers, the flow of radiative energy toward regions of higher energy density, and the creation of secondary shocks by ablation of the tube walls ahead of the primary shock front. Simulations of one such experimental system are also shown.

    We review recent progress on collisionless relativistic shocks. Kinetic instability theory is briefed including its predictions and limitations. The main focus is on numerical experiments in (i) pair and (ii) electron-nucleon plasmas. The main results are: (i) confirmation of shock evolution in non-magnetised relativistic plasma in 3D due to either the lepton-Weibel instability or the ion-Weibel instability; (ii) sensitive dependence on upstream magnetisation ; (iii) the sensitive dependence of particle dynamics on the upstream magnetic inclination angle $\\thetabn$, where particles of $\\thetabn>34^\\circ$ cannot escape upstream, leading to the distinction between `sub-luminal' and `super-luminal' shocks; (iv) particles in ultra-relativistic shocks can hardly overturn the shock and escape to upstream; they may oscillate around the shock ramp for a long time, so to speak `surfing it' and thereby becoming accelerated by a kind of SDA; (v) these particles form a power law tail on the downstream distribution; their...

  5. Shock wave treatment in medicine

    Extracorporeal shock wave therapy in orthopedics and traumatology is still a young therapy method. Since the last few years the development of shock wave therapy has progressed rapidly. Shock waves have changed the treatment of urolithiasis substantially. Today shock waves are the first choice to treat kidney and urethral stones. Urology has long been the only medical field for shock waves in medicine. Meanwhile shock waves have been used in orthopedics and traumatology to treat insertion tendinitis, avascular necrosis of the head of femur and other necrotic bone alterations. Another field of shock wave application is the treatment of tendons, ligaments and bones on horses in veterinary medicine. In the present paper we discuss the basic theory and application of shock waves and its history in medicine. The idea behind using shock wave therapy for orthopedic diseases is the stimulation of healing in tendons, surrounding tissue and bones. This is a completely different approach compared to urology where shock waves are used for disintegration.

    2015-01-01

    Shock waves exist throughout the universe and are fundamental to understanding the nature of collisionless plasmas. Reformation is a process, driven by microphysics, which typically occurs at high Mach number supercritical shocks. While ongoing studies have investigated this process extensively both theoretically and via simulations, their observations remain few and far between. In this letter we present a study of very high Mach number shocks in a parameter space that has been poorly explored and we identify reformation using in situ magnetic field observations from the Cassini spacecraft at 10 AU. This has given us an insight into quasi-perpendicular shocks across two orders of magnitude in Alfven Mach number (MA) which could potentially bridge the gap between modest terrestrial shocks and more exotic astrophysical shocks. For the first time, we show evidence for cyclic reformation controlled by specular ion reflection occurring at the predicted timescale of ~0.3 {\\tau}c, where {\\tau}c is the ion gyroperio...

    Interplanetary shocks are associated to approximately one third of the CMEs detected in the interplanetary medium. Even though they have been associated to fast CMEs (V>1000 km/s) it has been shown that some slow ones (V 300 km/s) presented shocks at 1 AU. The structure of the features observed in coronograph images can be hardly compared to the ones detected beyond the coronograph field of view, where the shock is clearly identify. For a few cases, the shock in front of the CME has been distinguish in white light images, but, is there a real visual difference between the CME itself and the considered shock? In this work we compare the optical characteristics of CMEs and some hydrodynamic parameters of ICMEs to show that the feature observed in white light images can be considered as a shock structure.

  15. How to develop a phenomenological model of disability.

    Science.gov (United States)

    Martiny, Kristian Moltke

    2015-11-01

    During recent decades various researchers from health and social sciences have been debating what it means for a person to be disabled. A rather overlooked approach has developed alongside this debate, primarily inspired by the philosophical tradition called phenomenology. This paper develops a phenomenological model of disability by arguing for a different methodological and conceptual framework from that used by the existing phenomenological approach. The existing approach is developed from the phenomenology of illness, but the paper illustrates how the case of congenital disabilities, looking at the congenital disorder called cerebral palsy (CP), presents a fundamental problem for the approach. In order to understand such congenital cases as CP, the experience of disability is described as being gradually different from, rather than a disruption of, the experience of being abled, and it is argued that the experience of disability is complex and dynamically influenced by both intrinsic and extrinsic factors. Different experiential aspects of disability- pre-reflective, attuned and reflective aspects-are described, demonstrating that the experience of disability comes in different degrees. Overall, this paper contributes to the debates about disability by further describing the personal aspects and experience of persons living with disabilities.

  2. Perceptual Anomalies in Schizophrenia: Integrating Phenomenology and Cognitive Neuroscience

    Science.gov (United States)

    Uhlhaas, Peter J.; Mishara, Aaron L.

    2007-01-01

    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
