    This paper presents findings from a two-phase mixed methods study investigating the phenomenological structure of self-relevance among ninth-grade junior high school biology students (Phase 1: N = 118; Phase 2: N = 139). We begin with a phenomenological multidimensional definition of self-relevance as comprising three dimensions: the academic…

  2. Relevance of protection quantities in medical exposures

    2008-01-01

    International Commission on Radiological Protection (ICRP) continues to classify the exposures to radiation in three categories; namely 1- occupational exposure, 2- public exposure, and 3- medical exposure. Protection quantities are primarily meant for the regulatory purpose in radiological protection for controlling and limiting stochastic risks in occupational and public exposures. These are based on two basic assumptions of 1- linear no-threshold dose-effect relationship (LNT) at low doses and 2- long-term additivity of low doses. Medical exposure are predominantly delivered to individuals (patients) undergoing diagnostic examinations, interventional procedures and radiation therapy but also include individual caring for or comforting patients incurring exposure and the volunteers of biomedical medical research programmes. Radiation protection is as relevant to occupational and public exposure as to medical exposures except that the dose limits set for the formers are not applicable to medical exposure but reference levels and dose constrains are recommended for diagnostic and interventional medical procedures. In medical institutions, both the occupational and medical exposure takes place. Since the doses in diagnostic examinations are low, it has been observed that not only the protection quantities are often used in such cases but these are extended to estimate the number of cancer deaths due to such practices. One of the striking features of the new ICRP recommendations has been to elaborate the concepts of the dosimetric quantities. The limitation of protection quantities ((Effective dose, E=Σ RT D TR .W T .W R and Equivalent Dose H T =Σ RT D TR .W R ) have been brought out and this has raised a great concern and initiated debates on the use of these quantities in medical exposures. Consequently, ICRP has set a task group to provide more details and the recommendations. It has, therefore, became important to draw the attention of medical physics community

    The method of QCD sum rules is used here to evaluate vacuUm expectation values (VEV) for various four-fermion operators. It is found that the VEV (anti uσsub(μν) lambda sup(α)d anti d σsub(μν) lambda sup(α)u) is by a factor of 3-3.5 larger than the factorized quantity, while the VEV (anti u lambda sup(α) d anti d lambda sup(α) u) is smaller by a factor of 3-5 A by-product of the work is a phenomenological estimate for the VEV (gsup(3)fsup(abc)Gsub(μν)sup(α)Gsub(ν lambda)sup(b)Gsub(lambda μ)sup(c)) approximately equal to 0.06 GeV 6

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

    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.

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

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

  6. Dreaming Consciousness: A Contribution from Phenomenology

    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.

  8. A phenomenological attempt at understanding otherness

    2017-12-01

    Full Text Available The phenomenology of otherness is not satisfied with the reductionist definitions of the classical anthropological conceptions. The latter have identified the essence of man in his rationality, morality, createdness, or the possibility of moral and aesthetic self-perfection. The monolithic definition of human essence, based on uniform criteria, seems today one-sided and outdated. The parallel effects of cultural diversification, the pluralized political and social system, and multilingualism have directly and inevitably confronted us with otherness and strangeness. We could even say that we can understand our identity primarily through the experience of otherness. We will reach our conclusions related to the phenomenological constitutive of otherness by way of the interpretation of the relevant ideas of Baudrillad, Guillaume and Lévinas.

  9. Phenomenological modeling of turbulence in Z-pinch implosions

    1994-01-01

    A phenomenological investigation into the effects of magnetohydrodynamic (MHD) turbulence on the initial stagnation dynamics of aluminum wire array and argon gas puff Z-pinch implosions is performed. The increases that turbulence produces in the plasma viscosity, heat conductivity, and electrical resistivity are modeled by using multipliers for these quantities in one-dimensional (1-D) MHD calculations. The major effect of these increases is to soften the 1-D implosions by decreasing the densities that are achieved on axis at stagnation. As a consequence, a set of multipliers can be found that reasonably duplicates the average electron temperatures, ion densities, and mass of the K-shell emission region that were measured at stagnation for a variety of Physics International aluminum wire array and argon gas puff experiments. It is determined that the dependence of these measured quantities on the multipliers is weak once a level of enhancement is reached, where agreement between calculations and experiments is attained. The scaling of K-shell yield with load mass for a fixed implosion velocity is then reexamined, and the minimum load mass needed to efficiently produce K-shell emission by thermalization of kinetic energy is calculated for aluminum and argon using this phenomenological soft implosion modeling. The results show an upward shift in the minimum mass by a factor of 6 when compared to the original nonturbulent hard implosion calculations

    Phenomenology is a philosophic attitude and research approach. Its primary position is that the most basic human truths are accessible only through inner subjectivity, and that the person is integral to the environment. This paper discusses the theoretical perspectives related to phenomenology, and includes a discussion of the methods adopted in phenomenological research.

    The phenomenology of the standard Weinberg-Salam Higgs boson is reviewed with particular emphasis on production mechanisms in high energy e + e - and hadron-hadron collisions. The production processes relevant for the ISABELLE and TEVATRON energies are discussed and their backgrounds estimated. It is argued that the toponium production and radiative decay provides the most hopeful reaction to detect a Higgs in both the e + e - and the hadron-hadron machines. (orig.)

    Surface tension provides a thermodynamic avenue for analyzing systems in equilibrium and formulating phenomenological explanations for the behavior of constituent molecules in the surface region. While there are extensive experimental observations and established ideas regarding desorption of ions from the surfaces of aqueous salt solutions, a more successful discussion of the theory has recently emerged, which allows the quantitative calculation of the distribution of ions in the surface region.

    2018-05-01

    Full Text Available This paper deals with the methodological role played by the term «motivation» in young Heidegger’s early hermeneutic transformation of phenomenology. To that effect, I shall start analyzing the concept of motivation in Husserl’s phenomenology so as to better understand its hermeneutical variation in young Heidegger’s philosophy. Subsequently, I will pay special attention to the relevance exhibited by motivation in the emergence of the most important methodological notions of hermeneutical phenomenology as «destruction» (Destruktion, «formal indication» (formale Anzeige and «preconception» (Vorgriff. To conclude, I shall explore the possibility of reshaping the phenomenological problem of the motivation to reduction in hermeneutical terms. That is to say: a motivation to reduction in factical life experience is always needed to access to the primordial sphere of meaning. Accordingly, I will finally suggest that the philosophical basic experience of radical questioning (Fraglichkeit can be read as a hermeneutical epoche, which is, however, directly linked to the concern for one’s own existence.

  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.

    1979-01-01

    The author presents an argument that phenomenological Lagrangians can be used not only to reproduce the soft pion results of current algebra, but also to justify these results, without any use of operator algebra, and shows how phenomenological Lagrangians can be used to calculate corrections to the leading soft pion results to any desired order in external momenta. The renormalization group is used to elucidate the structure of these corrections. Corrections due to the finite mass of the pion are treated and speculations are made about another possible application of phenomenological Lagrangians. (Auth.)

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

    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. Copyright © 2016 Elsevier Inc.

    2008-09-01

    This review focuses on phenomenological studies of delirium, including subsyndromal and prodromal concepts, and their relevance to other elements of clinical profile. A Medline search using the keywords delirium, phenomenology, and symptoms for new data articles published in English between 1998 and 2008 was utilized. The search was supplemented by additional material not identified by Medline but known to the authors. Understanding of prodromal and subsyndromal concepts is still in its infancy. The characteristic profile can differentiate delirium from other neuropsychiatric disorders. Clinical (motoric) subtyping holds potential but more consistent methods are needed. Studies are almost entirely cross-sectional in design and generally lack comprehensive symptom assessment. Multiple assessment tools are available but are oriented towards hyperactive features and few have demonstrated ability to distinguish delirium from dementia. There is insufficient evidence linking specific phenomenology with etiology, pathophysiology, management, course, and outcome. Despite the major advancements of the past decade in many aspects of delirium research, further phenomenological work is crucial to targeting studies of causation, pathophysiology, treatment, and prognosis. We identified eight key areas for future studies.

    The authors investigate some of the effects of plasma turbulence on the K-shell emission dynamics of argon gas puff Z-pinch implosions. The increases that turbulence produces in the plasma viscosity, heat conductivity, and electrical resistivity are modeled phenomenologically using multipliers for these quantities in the MHD calculations. The choice of multipliers was made by benchmarking a 1-D MHD simulation of a Physics International Inc. argon gas puff experiment against the inferred densities and temperatures achieved in the experiment. These multipliers were then used to study the parametric dependence of the K-shell emission on the energy input to the argon plasma for a fixed mass loading. Comparisons between turbulent and non-turbulent argon implosions are made

  2. Stop, look, listen: the need for philosophical phenomenological perspectives on auditory verbal hallucinations

    2013-01-01

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

    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.

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

    van Manen, Max

    2017-05-01

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

    Full Text Available The research carried out on the following strategic phenomenon, for the most part, the guidelines of the functionalist paradigm. This production has its relevance in the scientific community, however, does not cover the strategy in all its complexity. In this scenario, it is intended to address the strategy from the assumptions of social phenomenology, an online research study focused on the action. Social action is the experience of the phenomenon. For this, research is carried out "for reasons" and "why reasons" present in strategic action. The relevance of this study is to address the strategy as a phenomenon that exists because of the social subject, which may show that its essence transcends the limits of individuality, because thinking is based on the phenomenological social awareness of the existence of the other. Held semi-structured interviews with fourteen strategists operating in cluster of furniture Bento Gonçalves, and the data analyzed according to the phenomenological approach of Sanders (1982. As a result, it follows that the "why reasons" are the 'becoming' and expertise, and the "for reasons": the search for freedom in corporate decision making and building a legacy. We conclude that the meaning of strategic action is not isolated, being linked to several factors related to the existential project of the strategist.

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

    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.

    Thin, solid bodies with metric symmetries admit a restricted form of reparameterization invariance. Their dynamical equilibria include motions with both rigid and flowing aspects. On such configurations, a quantity is conserved along the intrinsic coordinate corresponding to the symmetry. As an example of its utility, this conserved quantity is combined with linear and angular momentum currents to construct solutions for the equilibria of a rotating, flowing string, for which it is akin to Bernoulli's constant. - Highlights: • A conserved quantity relevant to the dynamical equilibria of thin structures. • A mixed Lagrangian–Eulerian non-material action principle for fixed windows of axially moving systems. • Analytical solutions for rotating, flowing strings (yarn balloons). • Noether meets Bernoulli in a textile factory.

    Full Text Available Phenomenology, as the study of structures of subjective experiences and consciousness, finds itself in the persistent struggle to claim its rightful place in contemporary research. Accordingly, this article will point out the relevance of first person reports for interdisciplinary investigations of the brain and mind. This is done by exploring the multidisciplinary field of food studies as a novel platform for discussion. The phenomenological inquiry is thus proposed as the vehicle and method to access food-related experience. By highlighting the important surplus, essential to grasping the process of pristine inner experience we adjoin a new perspective to the common focus on the content of experience. Consequently, this will extend the current insights pertinent to food-related research and moreover, give vital implications to our overall construction of concepts in science.

  14. Philosophy of phenomenology: how understanding aids research.

    Converse, Mary

    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.

    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. PMID:22076123

    2017-08-01

    We explore the phenomenology of Elastically Decoupling Relic (ELDER) dark matter. ELDER is a thermal relic whose present density is determined primarily by the cross-section of its elastic scattering off Standard Model (SM) particles. Assuming that this scattering is mediated by a kinetically mixed dark photon, we argue that the ELDER scenario makes robust predictions for electron-recoil direct-detection experiments, as well as for dark photon searches. These predictions are independent of the details of interactions within the dark sector. Together with the closely related Strongly-Interacting Massive Particle (SIMP) scenario, the ELDER predictions provide a physically motivated, well-defined target region, which will be almost entirely accessible to the next generation of searches for sub-GeV dark matter and dark photons. We provide useful analytic approximations for various quantities of interest in the ELDER scenario, and discuss two simple renormalizable toy models which incorporate the required strong number-changing interactions among the ELDERs, as well as explicitly implement the coupling to electrons via the dark photon portal.

    It is noted that the nonlinear evolution equation usub(t) = α(t)usub(xxx) - 6ν(t) usub(x)u, u is identical to u(x,t), possesses three (and, in some cases, four) conserved quantities, that are explicitly displayed. These results are of course relevant only to the cases in which this evolution equation is not known to possess an infinite number of conserved quantities. Purpose and scope of this paper is to report three or four simple conservation laws possessed by the evolution equation usub(t) = α(t)usub(xxx) - 6ν(t)usub(x)u, u is identical to u(x,t). (author)

  3. Contribution to the phenomenological study of meson-baryon reactions at high energy

    International Nuclear Information System (INIS)

    Girardi, Georges.

    The report is divided into two sections corresponding to the two approaches used in the study of 2-body reactions. Part one is devoted to the building of a new phenomenological model, calling on a wide range of theoretical concepts such as duality, quark diagrams, SU(3) symmetry etc... The model thus established is compared with experimental results and seems to resolve certain difficulties which other models cannot avoid. In part two the approach adopted is more typically phenomenological, involving analyses in amplitudes which amounts to the consultation of experience, avoiding, as far as possible, the use of over-specific theoretical concepts. The various results obtained certain regularities in the amplitudes, evidence of underlaying physical laws as yet little understood. From this study an empirical relationship is proposed for two-body scattering amplitudes. This relationship, which considerably simplifies the formulation of phenomenological models, has already been used successfully to study certain processes. The results of these two approaches are shown to agree, which points up the relevance of the physical images used and helps in the understanding of high-energy hadron interactions [fr

  4. Embodiment and psychopathology: a phenomenological perspective.

    Science.gov (United States)

    Fuchs, Thomas; Schlimme, Jann E

    2009-11-01

    To survey recent developments in phenomenological psychopathology. We present the concept of embodiment as a key paradigm of recent interdisciplinary approaches from the areas of philosophy, psychology, psychiatry and neuroscience. This requires a short overview on the phenomenological concept of embodiment; in particular, on the distinction of subject and object body. A psychopathology of embodiment may be based on these and other distinctions, in particular on a polarity of disembodiment and hyperembodiment, which is illustrated by the examples of schizophrenia and depression. Recent contributions to phenomenological accounts of these disorders are presented. Finally, the study discusses the relationship of phenomenological and neuropsychiatric perspectives on embodiment. A phenomenology of embodiment may be combined with enactive approaches to cognitive neuroscience in order to overcome dualist concepts of the mind as an inner realm of representations that mirror the outside world. Phenomenological and ecological concepts of embodiment should also be conjoined to enable a new, advanced understanding of mental illness.

  6. Phenomenology of atmospheric neutrinos

    Fedynitch Anatoli

    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.

  7. Identification techniques for phenomenological models of hysteresis based on the conjugate gradient method

    Andrei, Petru; Oniciuc, Liviu; Stancu, Alexandru; Stoleriu, Laurentiu

    2007-01-01

    An identification technique for the parameters of phenomenological models of hysteresis is presented. The basic idea of our technique is to set up a system of equations for the parameters of the model as a function of known quantities on the major or minor hysteresis loops (e.g. coercive force, susceptibilities at various points, remanence), or other magnetization curves. This system of equations can be either over or underspecified and is solved by using the conjugate gradient method. Numerical results related to the identification of parameters in the Energetic, Jiles-Atherton, and Preisach models are presented

  8. Being Mindful as a Phenomenological Attitude.

    Science.gov (United States)

    Gustin, Lena Wiklund

    2017-08-01

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

    This paper argues that phenomenological insights regarding selfhood are relevant to the informed consent process in the treatment of depression using electro-convulsive therapy (ECT). One of the most significant side-effects associated with ECT is retrograde amnesia. Unfortunately, the current informed consent model does not adequately appreciate the full extent in which memory loss disturbs lived-experience. Through the philosophy of Merleau-Ponty, it is possible to appreciate the way in whi...

  10. Narcissism, self-esteem, and the phenomenology of autobiographical memories.

    Science.gov (United States)

    Jones, Lara L; Norville, Gregory A; Wright, A Michelle

    2017-07-01

    Across two studies, we investigated the influence of narcissism and self-esteem along with gender on phenomenological ratings across the four subscales of the Autobiographical Memory Questionnaire (AMQ; impact, recollection, rehearsal, and belief). Memory cues varied in valence (positive vs. negative) and agency (agentic vs. communal). In Study 2, we used different memory cues reflecting these four Valence by Agency conditions and additionally investigated retrieval times for the autobiographical memories (AMs). Results were consistent with the agency model of narcissism [Campbell, W. K., Brunell, A. B., & Finkel, E. J. (2006). Narcissism, interpersonal self-regulation, and romantic relationships: An agency model approach. In E. J. Finkel & K. D. Vohs (Eds.), Self and relationships: Connecting intrapersonal and interpersonal processes. New York, NY: Guilford], which characterises narcissists as being more concerned with agentic (self-focused) rather than communal (other-focused) positive self-relevant information. Narcissism predicted greater phenomenology across the four subscales for the positive-agentic memories (Study 1: clever; Study 2: attractive, talented) as well as faster memory retrieval times. Narcissism also predicted greater recollection and faster retrieval times for the negative-communal AMs (Study 1: rude; Study 2: annoying, dishonest). In contrast, self-esteem predicted greater phenomenology and faster retrieval times for the positive-communal AMs (Study 1: cooperative; Study 2: romantic, sympathetic). In both studies, results of LIWC analyses further differentiated between narcissism and self-esteem in the content (word usage) of the AMs.

  11. Fitting the Phenomenological MSSM

    AbdusSalam, S S; Quevedo, F; Feroz, F; Hobson, M

    2010-01-01

    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.

    Although cognitive science has recently asked how human sociality is constituted, there is no clear and consistent account of the emergence of human style social agency. Previously, we have critiqued views based on 'participatory sense-making' by arguing that agency requires a distinctive kind...... of phenomenology that enables a diachronic social experience. In advancing the positive argument, we link developmental psychology to phenomenological insights by focusing on child-caregiver dynamics around the middle of the second year. Having developed very basic social skills, an infant comes to feel normative....... Developmental events thus transform the child's experience and drive the emergence of social agency. Once the child has successfully dealt with the environment’s normative perturbations she is able to develop the skills of a fully-fledged human social agent....

    International Nuclear Information System (INIS)

    Cavopol, A.V.

    1987-01-01

    We develop a phenomenological Lagrangian that satisfies the requirements of the so called alternative schemes designed to model low energy meson phenomenology. Linear and nonlinear σ type Lagrangians and symmetry breaking schemes are used to describe pions that exhibit masses proportional to the square of the symmetry breaking term's coefficient, ε. (m π 2 ∼ 0(ε 2 )). The invariance of the theory under coordinate dependent transformations is achieved by introducing gauge fields for both linear and nonlinear Lagrangians. Finally, analogies between the minimal symmetry breaking terms in Quantum Electrodynamics and in our phenomenological lagrangians are used to generate a discussion of the quark-pion mass dependence indicated by the model

  18. Multiple nano elements of SCC--transition from phenomenology to predictive mechanistics

    International Nuclear Information System (INIS)

    Staehle, R.W.

    2009-01-01

    Full text of publication follows: Predicting the occurrence and rate of stress corrosion cracking in materials of construction is one of the most critical pathways for assuring the reliability of light water nuclear reactor plants. It is the general intention of operators of nuclear plants that they continue performing satisfactorily for times of 60 to 80 years at least. Such times are beyond existing experience, and there are no bases for choosing credible predictions. Present bases for predicting SCC rely on anecdotal experience for predicting what materials sustain SCC in specified environments and on phenomenological correlations using such parameters as K (stress intensity), 1/T (temperature), E(corr) (corrosion potential), pH, [x] a (concentration), other established quantities, and statistical correlations. While these phenomenological correlations have served the industry well in the past, they have also allowed grievous mistakes. Further, such correlations are flawed in their fundamental credibility. Predicting SCC in aqueous solutions means to predict its dependence upon the seven primary variables: potential, pH, species, alloy composition, alloy structure, stress and temperature. A serious prediction of SCC upon these seven primary variables can only be achieved by moving to fundamental nano elements. Unfortunately, useful predictability from the nano approach cannot be achieved quickly or easily; thus, it will continue to be necessary to rely on existing phenomenology. However, as the nano approach evolves, it can contribute increasingly to the quantitative capacity of the phenomenological approach. The nano approach will require quite different talents and thinking than are now applied to the prediction of SCC; while some of the boundary conditions of phenomenology must continue to be applied, elements of the nano approach will include accounting for at least, typically, the following multiple elements as they apply at the sites of initiation and at

    We discuss the collider phenomenology of the model of Minimal Universal Extra Dimensions (MUED) at the Large hadron Collider (LHC). We derive analytical results for all relevant strong pair-production processes of two level 1 Kaluza-Klein partners and use them to validate and correct the existing MUED implementation in the fortran version of the PYTHIA event generator. We also develop a new implementation of the model in the C++ version of PYTHIA. We use our implementations in conjunction with the CHECKMATE package to derive the LHC bounds on MUED from a large number of published experimental analyses from Run 1 at the LHC.

  2. 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.

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

    2018-05-11

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

    Høffding, Simon

    This dissertation develops a phenomenology of expert musicianship through an interdisciplinary approach that integrates qualitative interviews with the Danish String Quartet with philosophical analyses drawing on ideas and theses found in phenomenology, philosophy of mind, cognitive science...... and psychology of music. The dissertation is structured through the asking, analyzing and answering of three primary questions, namely: 1) What is it like to be an expert? 2) What is the general phenomenology of expert musicianship? 3) What happens to the self in deep musical absorption? The first question...... targets a central debate in philosophy and psychology on whether reflection is conducive for, or detrimental to, skillful performance. My analyses show that the concepts assumed in the literature on this question are poorly defined and gloss over more important features of expertise. The second question...

  11. Feeling and time: the phenomenology of mood disorders, depressive realism, and existential psychotherapy.

    Ghaemi, S Nassir

    2007-01-01

    Phenomenological research suggests that pure manic and depressive states are less common than mixtures of the two and that the two poles of mood are characterized by opposite ways of experiencing time. In mania, the subjective experience of time is sped up and in depression it is slowed down, perhaps reflecting differences in circadian pathophysiology. The two classic mood states are also quite different in their effect on subjective awareness: manic patients lack insight into their excitation, while depressed patients are quite insightful into their unhappiness. Consequently, insight plays a major role in overdiagnosis of unipolar depression and misdiagnosis of bipolar disorder. The phenomenology of depression also is relevant to types of psychotherapies used to treat it. The depressive realism (DR) model, in contrast to the cognitive distortion model, appears to better apply to many persons with mild to moderate depressive syndromes. I suggest that existential psychotherapy is the necessary corollary of the DR model in those cases. Further, some depressive morbidities may in fact prove, after phenomenological study, to involve other mental states instead of depression. The chronic sub-syndromal depression that is often the long-term consequence of treated bipolar disorder may in fact represent existential despair, rather than depression proper, again suggesting intervention with existential psychotherapeutic methods.

  13. Phenomenological perspectives on self-care in aging

    Full Text Available Olle SöderhamnCenter for Caring Research- Southern Norway, Faculty of Health and Sport Sciences, University of Agder, Grimstad, NorwayAbstract: Self-care is a central concept in health care and may be considered as a means to maintain, restore, and improve one's health and well-being. When performed effectively, self-care contributes not only to human functioning but also to human structural integrity and human development (ie, to a dynamic and holistic state of health. Self-care as a clinical concept is relevant for health care professionals, and it should be meaningful to investigate it at a philosophical level and to further elaborate upon this concept. The aim of this article is to discuss and elaborate upon a phenomenological perspective on self-care in aging that is relevant for the health sciences. Self-care may be preliminarily regarded as a fundamental perspective for the conscious older individual, and as a way of being in the world with both the objective body and with the lived body. The lived body is the personal center of perception and the field of action, and it is also the center of self-care. The potentiality or ability for self-care activity and self-care activity itself are structures given to perception, with self-care ability as an integral part of the lived body. The actualization of self-care ability comes about through a certain meaning, which can be regarded as an important driving force. It is constituted by communication, a healthy lifestyle, and by building meaning and socializing. Successful self-care involves having contacts with the health care system, being conscious of a sound lifestyle, being physically and mentally active, being engaged, having social contacts with family and others, as well as being satisfied, positive, and being able to look forward. One fundamental cornerstone is serenity on behalf of the individual. Self-care can facilitate transitions, and it may also be an outcome of transitions

  14. Phenomenological realism, superconductivity and quantum mechanics

    International Nuclear Information System (INIS)

    Shomar, T.L.E.

    1998-01-01

    The central aim of this thesis is to present a new kind of realism that is driven not from the traditional realism/anti-realism debate but from the practice of physicists. The usual debate focuses on discussions about the truth of theories and their fit with nature, while the real practices of the scientists are forgotten. The position I shall defend is called 'phenomenological realism': theories are merely tools to construct other theories and models, including phenomenological models; phenomenological models are the vehicles of representation. The realist doctrine was recently undermined by the argument from the pessimistic meta-induction, also known as the argument from scientific revolutions. I argue that phenomenological realism is a new kind of scientific realism which can overcome the problem generated by the argument from scientific revolutions, and which depend on the scientific practice. The realist tried to overcome this problem by suggesting various types of theory dichotomy. I claim that different types of dichotomy presented by realists did not overcome the problem, these dichotomies cut through theory vertically. I argue for a different kind of dichotomy between high level theoretical abstractions and low-level theoretical representations. I claim that theoretical work in physics have two distinct types depending on the way they are built these are: theoretical models which built depending on a top-down approach and phenomenological models which are built depending on a bottom-up approach, this dichotomy cuts the division along a horizontal line between low and high level theory. I present two case studies. One from superconductivity where I contrast the BCS theory of superconductivity with the phenomenological model of Landau and Ginzburg. I show how in that field of physics the historical developments favoured phenomenological models over high-level theoretical abstraction. I show how the BCS theory of superconductivity was constructed, and why it

    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.

    In this Letter, we investigate the phenomenologies of models where the Higgs sector plays the role of messengers in gauge mediation. The minimal Higgs sector and its extension are considered respectively. We find that there exist viable models when an appropriate parity is imposed. Phenomenological features in these kind of models include three sum rules for scalar masses, light gluino as well as one-loop {mu} and two-loop B{mu} terms.

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

    de Witt, Lorna; Ploeg, Jenny

    2006-07-01

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

    2013-01-01

    Starting with the ego's consciousness and emphasizing on staying at this realm, Husserl is accused of ignoring the absolute alterity of the other and reducing it to the presence of consciousness. By reducing the other he misses ethics and so embeds the violence at the heart of phenomenological discourse. Here we discuss on this criticism and then we try to defend Husserl against it. By putting phenomenology in its eidetic realm, we will try to answer these criticisms.

  2. Phenomenology of Freedom and Responsibility in Sartre’s Existentialist Ethics

    Directory of Open Access Journals (Sweden)

    Mindaugas Briedis

    2011-03-01

    Full Text Available Freedom and responsibility in one way or another were discussed by all exorcists of non-perspective thinking, i.e., existentialists. However, the phenomenological roots of existentialist ethics still did not receive proper academic attention. In this article I explore J. P. Sartre’s conception of freedom and responsibility uncovering how phenomenological insights can be subordinated and sometimes guide intentions of existentialism. On the other hand, Sartre’s view delivers perfect opportunity to analyse conflation of phenomenological ontology and existentialist ethics. Although Sartre interprets key notions of Husserl and Heidegger primarily in phenomenological manner, the analysis leads away from classical phenomenology and opens up a new outlook at classical ethical dilemmas. Thirdly, the lack of clear ethical claims in phenomenology could be reduced by showing that the ethical potential of phenomenology was partly actualized in existentialism. Besides these primary goals the article opens up a possibility to critically compare the conception of Sartre’s phenomenological-existentialist ethics with other ethical and ontological perspectives, i.e., stoicism, Christianity, psychoanalysis, Marxism, Kant and etc.

    Acoustic cloak based on coordinate transformation is of great topical interest and has promise in potential applications such as sound transparency and insulation. The frequency response of acoustic cloaks with a quantity of discrete homogeneous layers is analyzed by the acoustic scattering theory. The effect of coordinate transformation function on the acoustic total scattering cross section is discussed to achieve low scattering with only a few layers of anisotropic metamaterials. Also, the physics of acoustic wave interaction with the interfaces between the discrete layers inside the cloak shell is discussed. These results provide a better way of designing a multilayered acoustic cloak with fewer layers. (fundamental areas of phenomenology(including applications))

  4. Phenomenology as a resource for patients.

    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.

    Analysis of fluctuations of hadron production properties in collisions of relativistic particles profits from use of measurable intensive quantities which are independent of system size variations. The first family of such quantities was proposed in 1992; another is introduced in this paper. Furthermore we present a proof of independence of volume fluctuations for quantities from both families within the framework of the grand canonical ensemble. These quantities are referred to as strongly intensive ones. Influence of conservation laws and resonance decays is also discussed.

    The activity in sensory cortices and the prefrontal cortex (PFC) throughout the delay interval of working memory (WM) tasks reflect two aspects of WM-quality and quantity, respectively. The delay activity in sensory cortices is fine-tuned to sensory information and forms the neural basis of the precision of WM storage, while the delay activity in the PFC appears to represent behavioral goals and filters out irrelevant distractions, forming the neural basis of the quantity of task-relevant information in WM. The PFC and sensory cortices interact through different frequency bands of neuronal oscillation (theta, alpha, and gamma) to fulfill goal-directed behaviors.

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

    Science.gov (United States)

    Hong, Felix T

    2015-12-01

    Phenomenology aspires to philosophical analysis of humans' subjective experience while it strives to avoid pitfalls of subjectivity. The first step towards naturalizing phenomenology - making phenomenology scientific - is to reconcile phenomenology with modern physics, on the one hand, and with modern cellular and molecular neuroscience, on the other hand. In this paper, free will is chosen for a case study to demonstrate the feasibility. Special attention is paid to maintain analysis with mathematical precision, if possible, and to evade the inherent deceptive power of natural language. Laplace's determinism is re-evaluated along with the concept of microscopic reversibility. A simple and transparent version of proof demonstrates that microscopic reversibility is irreconcilably incompatible with macroscopic irreversibility, contrary to Boltzmann's claim. But the verdict also exalts Boltzmann's statistical mechanics to the new height of a genuine paradigm shift, thus cutting the umbilical cord linking it to Newtonian mechanics. Laplace's absolute determinism must then be replaced with a weaker form of causality called quasi-determinism. Biological indeterminism is also affirmed with numerous lines of evidence. The strongest evidence is furnished by ion channel fluctuations, which obey an indeterministic stochastic phenomenological law. Furthermore, quantum indeterminacy is shown to be relevant in biology, contrary to the opinion of Erwin Schrödinger. In reconciling phenomenology of free will with modern sciences, three issues - alternativism, intelligibility and origination - of free will must be accounted for. Alternativism and intelligibility can readily be accounted for by quasi-determinism. In order to account for origination of free will, the concept of downward causation must be invoked. However, unlike what is commonly believed, there is no evidence that downward causation can influence, shield off, or overpower low-level physical forces already known to

    Increasingly, researchers are recognizing the benefits of expanding research designs that are rooted in one tradition (i.e., monomethod design) into a design that incorporates or interfaces with the other tradition. The flexibility of phenomenologically driven methods provides one such example. Indeed, phenomenological research methods work extremely well as a component of mixed methods research approaches. However, to date, a mixed methods version of phenomenological research has not been fo...

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

    1998-09-01

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

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

    Spray-guided combustion processes for gasoline direct injection offer a great fuel saving potential. The quality of mixture formation has direct impact on combustion and emissions and ultimately on the technical feasibility of the consumption advantage. Therefore, it is very important to select the optimal mixture formation strategy. A systematic optimization of the mixture formation process based on experiments or three-dimensional computational fluid dynamics requires tremendous effort. An efficient alternative is the application-oriented, zero-dimensional numerical simulation of mixture formation. With a systemic model formulation in terms of global thermodynamic and fluid mechanical balance equations, the presented simulation model considers all relevant aspects of the mixture formation process. A comparison with measurements in a pressure/temperature chamber using laser-induced exciplex fluorescence tomography revealed a very satisfactory agreement between simulation and experiment. The newly developed, analytic-phenomenological spray propagation model precisely captures the injector-specific mixture formation characteristics of an annular-orifice injector in terms of penetration and volume. Vaporization rate and mean air/fuel ratio as the key quantities of mixture formation are correctly reproduced. Thus, the simulation model is suited to numerically assess the quality and to optimize the strategy of mixture formation. (orig.)

    1993-02-01

    This article presents philosophical approaches to research in physical therapy. A comparison is made to demonstrate how the research purpose, research design, research methods, and research data differ when one approaches research from the philosophical perspective of positivism (predominantly quantitative) as compared with the philosophical perspective of phenomenology (predominantly qualitative). Differences between the two approaches are highlighted by examples from research articles published in Physical Therapy. The authors urge physical therapy researchers to become familiar with the tenets, rigor, and knowledge gained from the use of both approaches in order to increase their options in conducting research relevant to the practice of physical therapy.

  16. Foreign materials in the repository - update of estimated quantities

    International Nuclear Information System (INIS)

    Hagros, A.

    2007-03-01

    In a repository for spent nuclear fuel, a variety of materials are used during the construction process and during the operation of the repository. In addition to materials necessary for the construction and operation, some materials may be transported into the repository through the ventilation air, as emissions from vehicles, as waste produced by the staff etc. Both of these two types of materials are considered here and their quantities - both the introduced quantities and the quantities that remain after closure - in the repository constructed at Olkiluoto in Eurajoki, Finland are estimated here based on new information. This work is intended to update the estimations that have been made previously, and it takes advantage of the experience collected during the construction of the underground rock characterisation facility ONKALO at Olkiluoto. During this construction process, the quantities of the different construction materials introduced into the underground openings have been monitored and they form a basis for estimating the quantities to be used in the future. The estimations made in this report are specific to a KBS-3V type repository and to the Olkiluoto site, although in some cases more generic information has been used, particularly when the relevant quantities have not been monitored in the ONKALO. The estimations are based on the new repository layout produced in 2006 and consider the latest plans for grouting and rock support. As these plans are generally not final yet, several different alternative plans are assumed when necessary. Also two different strategies for the backfilling of the tunnels are considered. The most significant differences with respect to the results of an earlier estimation are related to the materials used in grouting, shotcreting and in support bolts. In the cases where a mixture of bentonite and crushed rock is the used backfill alternative, gypsum and cement are the materials with the largest quantities remaining in the

    International Nuclear Information System (INIS)

    Bonvini, Marco; Forte, Stefano; Ridolfi, Giovanni

    2011-01-01

    We examine critically the theoretical underpinnings and phenomenological implications of soft gluon (threshold) resummation of rapidity distributions at a hadron collider, taking Drell-Yan production at the Tevatron and the LHC as a reference test case. First, we show that in perturbative QCD soft gluon resummation is necessary whenever the partonic (rather the hadronic) center-of-mass energy is close enough to threshold, and we provide tools to assess when resummation is relevant for a given process. Then, we compare different prescriptions for handling the divergent nature of the series of resummed perturbative corrections, specifically the minimal and Borel prescriptions. We assess the intrinsic ambiguities of resummed results, both due to the asymptotic nature of their perturbative expansion, and to the treatment of subleading terms. Turning to phenomenology, we introduce a fast and accurate method for the implementation of resummation with the minimal and Borel prescriptions using an expansion on a basis of Chebyshev polynomials. We then present results for W and Z production as well as both high- and low-mass dilepton pairs at the LHC, and show that soft gluon resummation effects are generally comparable in size to NNLO corrections, but sometimes affected by substantial ambiguities.

  1. How to develop a phenomenological model of disability

    DEFF Research Database (Denmark)

    Martiny, Kristian Møller Moltke

    2015-01-01

    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...

  2. Phenomenological aspects of the cognitive rumination construct

    Directory of Open Access Journals (Sweden)

    Leonardo Fernandez Meyer

    2015-03-01

    Full Text Available Objective: To evaluate the importance of phenomenological aspects of the cognitive rumination (CR construct in current empirical psychiatric research.Method: We searched SciELO, Scopus, ScienceDirect, MEDLINE, OneFile (GALE, SpringerLink, Cambridge Journals and Web of Science between February and March of 2014 for studies whose title and topic included the following keywords: cognitive rumination; rumination response scale; and self-reflection. The inclusion criteria were: empirical clinical study; CR as the main object of investigation; and study that included a conceptual definition of CR. The studies selected were published in English in biomedical journals in the last 10 years. Our phenomenological analysis was based on Karl Jaspers' General Psychopathology.Results: Most current empirical studies adopt phenomenological cognitive elements in conceptual definitions. However, these elements do not seem to be carefully examined and are indistinctly understood as objective empirical factors that may be measured, which may contribute to misunderstandings about CR, erroneous interpretations of results and problematic theoretical models.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.

  3. Phenomenology and theory of confinement

    International Nuclear Information System (INIS)

    Pervushin, V.N.

    1987-01-01

    Phenomenological and theoretical arguments of the separation of the hadronization dynamics from confinement and the idea of the ''kinematic'' confinement are discussed. The recent theory contains results which point out that the Wilson criterion and the confinement potentials are not sufficient for explaining the phenomenological confinement in the sense of zero color amplitudes or Green functions. However, these potentials well explain the hadron spectrum and spontaneous breaking of chiral symmetry, i.e., the hadronization dynamics. The ''kinematic'' confinement can be explained by the topological degeneration of all color-particle physical states in QCD. This degeneration arises if the theory is quantized by explicitly solving the gauge and dynamic constraints: all color states are defined up to gauge(phase) factors describing the map of the three-dimensional space onto SU(3) c -group (π 3 (SU(3) c =Z). The total probability of the color particle generation is equal to zero due to the destructive interference of these phase factors. As a result, in QCD there remains only a hadron sector used in the phenomenology

  5. 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.

  6. The use of phenomenology in mental health nursing research.

    Picton, Caroline Jane; Moxham, Lorna; Patterson, Christopher

    2017-12-18

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

    Observing the relics of collisions between bubble universes would provide direct evidence for the existence of an eternally inflating Multiverse; the non-observation of such events can also provide important constraints on inflationary physics. Realizing these prospects requires quantitative predictions for observables from the properties of the possible scalar field Lagrangians underlying eternal inflation. Building on previous work, we establish this connection in detail. We perform a fully relativistic numerical study of the phenomenology of bubble collisions in models with a single scalar field, computing the comoving curvature perturbation produced in a wide variety of models. We also construct a set of analytic predictions, allowing us to identify the phenomenologically relevant properties of the scalar field Lagrangian. The agreement between the analytic predictions and numerics in the relevant regions is excellent, and allows us to generalize our results beyond the models we adopt for the numerical studies. Specifically, the signature is completely determined by the spatial profile of the colliding bubble just before the collision, and the de Sitter invariant distance between the bubble centers. The analytic and numerical results support a power-law fit with an index 1< κ ∼< 2. For collisions between identical bubbles, we establish a lower-bound on the observed amplitude of collisions that is set by the present energy density in curvature.

  10. Foreign materials in the repository. Update of estimated quantities

    International Nuclear Information System (INIS)

    Karvonen, T.

    2011-06-01

    A variety of materials are used during the construction process and the operation of the repository for spent nuclear fuel at Olkiluoto in Eurajoki, Finland. In addition to materials necessary for the construction and operation, some materials may be transported into the repository with the ventilation air, as emissions from vehicles etc. Both of these two types of materials are considered here and both introduced quantities and the quantities that remain after the closure in the repository are estimated here based on the most recent information. This work is intended to update the previous estimations, and it takes advantage of the experience collected during the construction of the underground rock characterisation facility called ONKALO at Olkiluoto. The implemented quantities as well as designs and preliminary designs have been used in calculating the quantities of the foreign materials. The estimations made in this report are specific to a KBS-3V type repository. In some cases more generic information has been used, particularly when the relevant quantities have not been monitored in ONKALO. The estimations are based on the new repository layout produced in 2010 and consider the latest plans for grouting and rock support. As all of these plans are not final some quantities may change in the future. As the repository layout may still go through some changes this report also provides the foreign materials for a hundred meters of different deposition tunnels designed for the OL and LO type canisters1. The results have also been calculated for a space demanded by a deposition tunnel end plug and the tunnel lengths before and after one. The most significant foreign materials are certain accessory minerals of the clay materials followed by organic materials (including the organic carbon from the clay materials), cement, steel and silica.

    Hawk, E. A.; McNeil, J. A.

    2001-04-01

    In this work deuteron stripping reactions are studied using the distorted wave born approximation employing dirac phenomenological potentials. In 1982 Shepard and Rost performed zero-range dirac phenomenological stripping calculations and found a dramatic reduction in the predicted cross sections when compared with similar nonrelativistic calculations. We extend the earlier work by including full finite range effects as well as the deuteron's internal D-state. Results will be compared with traditional nonrelativistic approaches and experimental data at low energy.

    The standard phenomenology of the soft pomeron is recalled. The evidence for the soft pomeron having a well-defined Parton content is outlined. The role of the pomeron in deep inelastic scattering at small x is discussed, and it is suggested that the standard phenomenology is incompatible with the HERA data. It is shown how minijets can be included naturally as part of the soft pomeron, and that they do not contribute separately to total cross sections

    Full Text Available Inspired by Husserlian phenomenology, Piero Bertolini defined the phenomenological pedagogy and education as a scientific discipline (Bertolini, 2005. This project remains an undetermined one as there is still room for defining its research methods. This article intends to propose a contribution to the discussion of research methodology, in line with the assumptions of Piero Bertolini (1988 phenomenological pedagogy. In particular, starting from the definition of phenomenological pedagogy and education, it aims to answer the question: what are the research strategies through which to build a viable and rigorous educational knowledge, able to grasp the personal transformation and development in a context of inter-subjectivity? Accordingly, I shall discuss data collection and analysis strategies.

    2016-11-01

    Full Text Available Martin Heidegger’s phenomenology provides methodological guidance for qualitative researchers seeking to explicate the lived experience of study participants. However, most phenomenological researchers apply his philosophy loosely. This is not surprising because Heidegger’s phenomenological philosophy is challenging and the influence of his philosophy in shaping the conduct of interpretive phenomenological research is broadly debated. This article presents an exploration of Dasein, a key tenet of Martin Heidegger’s interpretive phenomenology and explicates its usefulness for phenomenological research. From this perspective, we present guidance for researchers planning to utilize Heidegger’s philosophy underpinning their research.

    In this paper, both the phenomenological and microscopic neutron relativistic optical potentials are presented. The global neutron relativistic phenomenological optical potential (RPOP) based on the available experimental data for various nuclei ranging from C to U with incident energies E n =20--1000 MeV has been obtained through an automatic search of the best parameters by computer. Then the nucleon relativistic microscopic optical potential (RMOP) is studied by utilizing the effective Lagrangian based on the popular Walecka model. Through comparison between the theoretical results and experimental data we shed some insight into both the RMOP and RPOP. Further improvement concerning how to combine the phenomenological potential with the microscopic one in order to reduce the number of free parameters appearing in the RPOP is suggested

  5. Phenomenology of stochastic exponential growth

    Science.gov (United States)

    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.

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

  11. Making Sense of the Works of Amar Kanwar: A Phenomenological Perspective

    Directory of Open Access Journals (Sweden)

    Christine Vial Kayser

    2016-09-01

    Full Text Available Amar Kanwar (b. 1964 is an Indian video and installation artist whose stated concern is violence in the context of South Asia. This article will examine two works, 'A Season Outside' (1997 and 'The Lightning ­Testimonies' (2007, proposing that empathy, intersubjectivity and a search for ­harmony, influenced both by Gandhi and Buddhism, are key concepts relevant to their interpretation while the choice of images and the editing process convey an embodied, phenomenological experience that is coherent with these influences. In addition it will infer from some evidence given by the works and by the artist that this search for social and collective harmony also has a psychological and individual dimension. It will be argued that the latter constitutes the true power of the works as the spectator does not so much reflect upon the violence exercised by the various perpetrators and experienced by the victims in a rational and political manner, but, rather, witnesses the film-maker’s reaction to the experience of violence; a situation which Vivian Sobchack has characterised as phenomenological. Through this process the spectator can empathise with the narrator and reflect on the affects examined by the works: namely violence and loss, but also love and compassion.

  12. Phenomenological theory of synergistic effects in plasma-wall interaction

    International Nuclear Information System (INIS)

    Itoh, N.; Hasebe, Y.

    1986-01-01

    A phenomenological theory for synergistic effects under multi-species particle bombardement has been developed. The theory is based on a model in which two free-energy minima are assumed to be overcome under actions of radiation for a process to be completed. The synergistic factor, the ratio of the yield of the process under irradiation with two species of particles to the summation of the yields of the process under irradiation with each of two component species, is obtained as a function of the beam flux for several parameters relevant to thermodynamic and radiation-enhanced processes. The criterion for the synergistic effect is obtained. The theory has been shown to be able to explain the yield-flux relation obtained by Haasz et al. for hydrogen-induced methane formation from graphite. (orig.)

    Luchetti, Martina; Rossi, Nicolino; Montebarocci, Ornella; Sutin, Angelina R

    2016-05-01

    Phenomenology is a critical component of autobiographical memory retrieval; it reflects both (a) memory-specific features and (b) stable individual differences. Few studies have tested phenomenology longitudinally. The present work examined the continuity of memory phenomenology in a sample of Italians adults (N=105) over a 4-week period. Participants retrieved two 'key' personal memories, a Turning Point and an Early Childhood Memory, rated the phenomenology of each memory, and completed measures of personality, psychological distress and subjective well-being. Phenomenological ratings were moderately stable over time (median correlation >.40), regardless of memory content. Personality traits, psychological distress and well-being were associated with phenomenology cross-sectionally and with changes in phenomenology over time. These results suggest that how individuals re-experience their most important personal memories is relatively consistent over time and shaped by both trait and state aspects of psychological functioning.

    Directory of Open Access Journals (Sweden)

    Patrick Frierson

    2016-06-01

    Full Text Available This paper explores the relationship between empirical psychology, transcendental critique, and phenomenology in Kant’s discussion of respect for the moral law, particularly as that is found in the Critique of Practical Reason. I first offer an empirical-psychological reading of moral respect, in the context of which I distinguish transcendental and empirical perspectives on moral action and defend H. J. Paton’s claim that moral motivation can be seen from two points of view, where “from one point of view, [respect] is the cause of our action, but from another point of view the moral law is its ground.” Then, after a discussion of a distinction between first- and second-order transcendental/practical perspectives where reasons for action are first-order practical judgments while the conditions of possibility for those reasons’ authority are expressed in second-order judgments, I turn to a third kind of perspective: the properly phenomenological one. I explain the general notion of Kantian phenomenology with an example of the experience of time from Kant’s Anthropology before applying this to a phenomenological reading of the discussion of respect in the Critique of Practical Reason. I end by noting that on my account, in contrast to that of Jeanine Grenberg, the distinctive phenomenology of respect is not systematically important for grounding claims in moral philosophy.

  20. Phenomenology and hermeneutics - poles apart?

    DEFF Research Database (Denmark)

    Keller, Kurt Dauer; Feilberg, Casper

    A key dispute within qualitative methodology is the choice between top-down (deductive) and bottom-up (inductive) research approaches. Abduction, on the other hand, has received little attention, even though it would often seem to be a more promising methodology. The phenomenological tradition is...... to qualitative methodology. Thus, like abductive approaches, Ricoeur argues for the necessity of an interplay between explanatory theory and description of the lived understanding of the informant in the development of interpretation....... is marked by a similar dichotomy, whereas hermeneutical phenomenologists argue for the necessity of preunderstanding and theorethical perspectives (van Manen), Husserlian phenomenologists insist on the importance of the epoché together with reduction. The existential phenomenology of Heidegger and Merleau...

    Martin Heidegger’s phenomenology provides methodological guidance for qualitative researchers seeking to explicate the lived experience of study participants. However, most phenomenological researchers apply his philosophy loosely. This is not surprising because Heidegger’s phenomenological philosophy is challenging and the influence of his philosophy in shaping the conduct of interpretive phenomenological research is broadly debated.

    An oft-cited phenomenological methodologist, Max VAN MANEN (2014), claims that qualitative data analysis software (QDAS) is not an appropriate tool for phenomenological research. Yet phenomenologists rarely describe how phenomenology is to be done: pencil, paper, computer? DAVIDSON and DI GREGORIO (2011) urge QDAS contrarians such as VAN MANEN to get over their methodological loyalties and join the digital world, claiming that all qualitative researchers, whatever their methodology, perform p...

  4. I'm shocked: informed consent in ECT and the phenomenological-self.

    Science.gov (United States)

    Seniuk, Patrick

    2018-02-13

    This paper argues that phenomenological insights regarding selfhood are relevant to the informed consent process in the treatment of depression using electro-convulsive therapy (ECT). One of the most significant side-effects associated with ECT is retrograde amnesia. Unfortunately, the current informed consent model does not adequately appreciate the full extent in which memory loss disturbs lived-experience. Through the philosophy of Merleau-Ponty, it is possible to appreciate the way in which memory loss affects a person's self-experience, with emphasis given to one's pre-reflective and embodied, relationship with things in the world. This paper aims to demonstrate that proper informed consent should acknowledge the extent to which repeated ECT treatments affect a patient's sense self.

  5. A review of the theory and phenomenology of lepton pair production

    International Nuclear Information System (INIS)

    Hwa, R.C.

    1978-05-01

    Recent experimental data and theoretical developments on the production of lepton pairs in hadron collisions are reviewed. With emphasis on the interplay between theory and experiment, the relevance of theoretical calculations to the data available at present energies is critically examined. The Drell-Yan mechanism is found to be phenomenologically dominant provided that the parton distribution functions contain effects of gluon radiation in a narrow cone. Explicit QCD perturbative calculations of the non-Drell-Yan type yield results that are apparently important at large transverse momenta, but are contradicted by subsequent data at 400 GeV and below. A consistent picture in the parton model is sketched. Further experiments to probe the basic mechanism are suggested. (author)

  6. Resonant diphoton phenomenology simplified

    International Nuclear Information System (INIS)

    Panico, Giuliano; Vecchi, Luca; 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 resonant diphoton production.

    Local oscillations of the brane world are manifested as massive vector fields. Their coupling to the Standard Model can be obtained using the method of nonlinear realizations of the spontaneously broken higher-dimensional space-time symmetries, and to an extent, are model independent. Phenomenological limits on these vector field parameters are obtained using LEP collider data and dark matter constraints

  10. 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).

  11. [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.

  13. Uncertainties of exposure-related quantities in mammographic x-ray unit quality control

    International Nuclear Information System (INIS)

    Gregory, Kent J.; Pattison, John E.; Bibbo, Giovanni

    2006-01-01

    Breast screening programs operate in many countries with mammographic x-ray units subject to stringent quality control tests. These tests include the evaluation of quantities based on exposure measurements, such as half value layer, automatic exposure control reproducibility, average glandular dose, and radiation output rate. There are numerous error sources that contribute to the uncertainty of these exposure-related quantities, some of which are unique to the low energy x-ray spectrum produced by mammographic x-ray units. For each of these exposure-related quantities, the applicable error sources and their magnitudes vary, depending on the test equipment used to make the measurement, and whether or not relevant corrections have been applied. This study has identified and quantified a range of error sources that may be used to estimate the combined uncertainty of these exposure-related quantities, given the test equipment used and corrections applied. The uncertainty analysis uses methods described by the International Standards Organization's Guide to the Expression of Uncertainty in Measurement. Examples of how these error sources combine to give the uncertainty of the exposure-related quantities are presented. Using the best test equipment evaluated in this study, uncertainties of the four exposure-related quantities at the 95% confidence interval were found to be ±1.6% (half value layer), ±0.0008 (automatic exposure control reproducibility), ±2.3% (average glandular dose), and ±2.1% (radiation output rate). In some cases, using less precise test equipment or failing to apply corrections, resulted in uncertainties more than double in magnitude

    Habit is a key concept in Husserl’s genetic phenomenology. In this paper, I want to flesh out Husserl’s conception of habit (for which he employs a wide variety of terms including: Habitus, Habitualität, Gewohnheit, das Habituelle, Habe, Besitz, Sitte, Tradition) to illustrate the complexity, range and depth of the phenomenological treatment of habit. I shall show that Husserl was by no means offering a limited Cartesian intellectualist explication of habitual action, rather he attempted to c...

  15. Quark-flavour phenomenology of models with extended gauge symmetries

    International Nuclear Information System (INIS)

    Carlucci, Maria Valentina

    2013-01-01

    Gauge invariance is one of the fundamental principles of the Standard Model of particles and interactions, and it is reasonable to believe that it also regulates the physics beyond it. In this thesis we have studied the theory and phenomenology of two New Physics models based on gauge symmetries that are extensions of the Standard Model group. Both of them are particularly interesting because they provide some answers to the question of the origin of flavour, which is still unexplained. Moreover, the flavour sector represents a promising field for the research of indirect signatures of New Physics, since after the first run of LHC we do not have any direct hint of it yet. The first model assumes that flavour is a gauge symmetry of nature, SU(3) 3 f , spontaneously broken by the vacuum expectation values of new scalar fields; the second model is based on the gauge group SU(3) c x SU(3) L x U(1) X , the simplest non-abelian extension of the Standard Model group. We have traced the complete theoretical building of the models, from the gauge group, passing through the nonanomalous fermion contents and the appropriate symmetry breakings, up to the spectra and the Feynman rules, with a particular attention to the treatment of the flavour structure, of tree-level Flavour Changing Neutral Currents and of new CP-violating phases. In fact, these models present an interesting flavour phenomenology, and for both of them we have analytically calculated the contributions to the ΔF=2 and ΔF=1 down-type transitions, arising from new tree-level and box diagrams. Subsequently, we have performed a comprehensive numerical analysis of the phenomenology of the two models. In both cases we have found very effective the strategy of first to identify the quantities able to provide the strongest constraints to the parameter space, then to systematically scan the allowed regions of the latter in order to obtain indications about the key flavour observables, namely the mixing parameters of

    Full Text Available The functionalist paradigm of organisational culture (OC views culture as a variable subject to conscious manipulation and control in order to solve organisational challenges. Therefore, this paper provides information on how OC is a solution to the challenges in Quantity Surveying firms (QSFs.  This was achieved by eliciting the dimensions of OC in forty two QSFs in Lagos, Nigeria, which are the business, people and external environment dimensions. The paper concludes that OC is a relevant solution to the identity and management related challenges in QSFs. Specifically, the paper informs on the implications of business and people dimensions of OC as a solution to the identity challenges, as well as on the implication of the external environment dimension of OC to the management challenges. Based on the findings, practical implications and recommendations were directed at the management and employees QSs in QSFs and Quantity Surveying researchers.

  17. Phenomenology of BWR fuel assembly degradation

    Science.gov (United States)

    Kurata, Masaki; Barrachin, Marc; Haste, Tim; Steinbrueck, Martin

    2018-03-01

    Severe accidents occurred at the Fukushima-Daiichi Nuclear Power Station (FDNPS) which required an immediate re-examination of fuel degradation phenomenology. The present paper reviews the updated knowledge on the phenomenology of the fuel degradation, focusing mainly on the BWR fuel assembly degradation at the macroscopic scale and that of the individual interactions at the meso-scale. Oxidation of boron carbide (B4C) control rods potentially generates far larger amounts of heat and hydrogen under BWR accident conditions. All integral tests with B4C control rods or control blades have shown early failure, liquefaction, relocation and oxidation of B4C starting at temperatures around 1250 °C, well below the significant interaction temperatures of UO2-Zry. These interactions or reactions potentially influence the progress of fuel degradation in the early phase. The steam-starved conditions, which are being discussed as a likely scenario at the FDNPS accident, highly influence the individual interactions and potentially lead the fuel degradation in non-prototypical directions. The detailed phenomenology of individual interactions and their influence on the transient and on the late phase of the severe accidents are also discussed.

    Pool, Natalie M

    2018-07-01

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

  1. Towards a Relational Phenomenology of Violence.

    Science.gov (United States)

    Staudigl, Michael

    This article elaborates a relational phenomenology of violence. Firstly, it explores the constitution of all sense in its intrinsic relation with our embodiment and intercorporality. Secondly, it shows how this relational conception of sense and constitution paves the path for an integrative understanding of the bodily and symbolic constituents of violence. Thirdly, the author addresses the overall consequences of these reflections, thereby identifying the main characteristics of a relational phenomenology of violence. In the final part, the paper provides an exemplification of the outlined conception with regard to a concrete phenomenon of violence, i.e., slapping, and a concluding reflection upon its overall significance for research on violence.

    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.)

  5. The orientation distribution of tunneling-related quantities

    Science.gov (United States)

    Seif, W. M.; Refaie, A. I.; Botros, M. M.

    2018-03-01

    In the nuclear tunneling processes involving deformed nuclei, most of the tunneling-related quantities depend on the relative orientations of the participating nuclei. In the presence of different multipole deformations, we study the variation of a few relevant quantities for the α-decay and the sub-barrier fusion processes, in an orientation degree of freedom. The knocking frequency and the penetration probability are evaluated within the Wentzel-Kramers-Brillouin approximation. The interaction potential is calculated with Skyrme-type nucleon-nucleon interaction. We found that the width of the potential pocket, the Coulomb barrier radius, the penetration probability, the α-decay width, and the fusion cross-section follow consistently the orientation-angle variation of the radius of the deformed nucleus. The orientation distribution patterns of the pocket width, the barrier radius, the logarithms of the penetrability, the decay width, and the fusion cross-section are found to be highly analogous to pattern of the deformed-nucleus radius. The curve patterns of the orientation angle distributions of the internal pocket depth, the Coulomb barrier height and width, as well as the knocking frequency simulate inversely the variation of the deformed nucleus radius. The predicted orientation behaviors will be of a special interest in predicting the optimum orientations for the tunneling processes.

  6. A general phenomenological model for work function

    Science.gov (United States)

    Brodie, I.; Chou, S. H.; Yuan, H.

    2014-07-01

    A general phenomenological model is presented for obtaining the zero Kelvin work function of any crystal facet of metals and semiconductors, both clean and covered with a monolayer of electropositive atoms. It utilizes the known physical structure of the crystal and the Fermi energy of the two-dimensional electron gas assumed to form on the surface. A key parameter is the number of electrons donated to the surface electron gas per surface lattice site or adsorbed atom, which is taken to be an integer. Initially this is found by trial and later justified by examining the state of the valence electrons of the relevant atoms. In the case of adsorbed monolayers of electropositive atoms a satisfactory justification could not always be found, particularly for cesium, but a trial value always predicted work functions close to the experimental values. The model can also predict the variation of work function with temperature for clean crystal facets. The model is applied to various crystal faces of tungsten, aluminium, silver, and select metal oxides, and most demonstrate good fits compared to available experimental values.

  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.

    A survey is given of supersymmetry and supergravity and their phenomenology. Some of the topics discussed are the basic ideas of global supersymmetry, the minimal supersymmetric Standard Model (MSSM) and its phenomenology, the basic ideas of local supersymmetry (supergravity), grand unification, supersymmetry breaking in supergravity grand unified models, radiative breaking of SU(2) x U(1), proton decay, cosmological constraints, and predictions of supergravity grand unified models. While the number of detailed derivations are necessarily limited, a sufficient number of results are given so that a reader can get a working knowledge of this field

  12. [Social actors and phenomenologic modelling].

    Science.gov (United States)

    Laflamme, Simon

    2012-05-01

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

  13. Phenomenology of unified gauge theories

    International Nuclear Information System (INIS)

    Ellis, J.

    1983-01-01

    Part I of these lectures treats the standard Glashow-Weinberg-Salam model of weak and electromagnetic interactions, discussing in turn its basic structure and weak neutral currents, charged currents, mixing angles and CP violation, and the phenomenology of weak vector and Higgs bosons. Part II of the lectures discusses the structure of theories of dynamical symmetry breaking such as technicolour, phenomenological consequences, frustrations and alternatives. The third part of these lectures offers the standard menu of grand unified theories (GUTs) of the strong, weak and electromagnetic interactions, including an hors d'oeuvre of constraints on the parameters of the standard model, a main course of baryon number violating processes, and desserts which violate lepton number and CP. The fourth and final part goes through different attempts to remedy the inadequacies of previous theories by invoking supersymmetry and reaching out towards gravitation. (orig./HSI)

    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.)

  17. Phenomenology of School Leaders' Experiences of Ethical Dilemmas

    OpenAIRE

    Guy, Timothy Michael

    2016-01-01

    This research study explores the intersection of school leadership and ethics. This study used the hermeneutic phenomenological approach described by Max Van Manen (1990, 2014) to explore the question: How do school leaders experience ethical dilemmas in their role as school leaders? Hermeneutic phenomenology seeks to find the meaning of a phenomenon, which in this case is the experience of an ethical dilemma. Hermeneutic refers to the interpretive-reflective-analytical component and phenom...

  3. Quantity Stickiness versus Stackelberg Leadership

    International Nuclear Information System (INIS)

    Ferreira, F. A.

    2008-01-01

    We study the endogenous Stackelberg relations in a dynamic market. We analyze a twice-repeated duopoly where, in the beginning, each firm chooses either a quantity-sticky production mode or a quantity-flexible production mode. The size of the market becomes observable after the first period. In the second period, a firm can adjust its quantity if, and only if, it has adopted the flexible mode. Hence, if one firm chooses the sticky mode whilst the other chooses the flexible mode, then they respectively play the roles of a Stackelberg leader and a Stackelberg follower in the second marketing period. We compute the supply quantities at equilibrium and the corresponding expected profits of the firms. We also analyze the effect of the slope parameter of the demand curve on the expected supply quantities and on the profits.

    2011-03-01

    Full Text Available The core of this article is the ancient question concerning the individual person in relation to his/her society. This fundamental question of ethics and political philosophy is approached from the perspective of phenomenological philosophy. Hence, this article is an attempt to conjoin two prima facie inconsistent (because of category mistake types of attitude towards reality and action, e.g. democracy and phenomenology. The thesis states that there is a common ground between the basic features of phenomenological method and the fundamental values of democracy. This paper explores the arguments that establish this parallelism between the values of democracy and phenomenology. One of the outcomes of this analysis will be the sketch of a new kind of virtue ethics and a new type of citizen, concerning new approaches to identity problem. In this respect method of phenomenology can be used as a technique (phronesis for a future citizenship. On the other hand, this perspective helps to re­evaluate the treasures of antique democracy and compare them with contemporary transformations of democracy in political, social and everyday spheres.

    El Haj, Mohamad; Nandrino, Jean-Louis

    2017-10-01

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

    We report a phenomenological two-nucleon interaction operator obtained by fitting the nucleon-nucleon phase shifts up to 425 MeV in S, P, D and F waves, and the deuteron properties. The operator has the standard eight potentials associated with the two-body operators 1, sigma 1 x sigma 2 , tau 1 x tau 2 , sigma 1 x sigma 2 tau 1 x tau 2 , S 12 , S 12 tau 1 x tau 2 , L x S and L x Stau 2 ; and six phenomenological potentials associated with operators L 2 , L 2 sigma 1 x sigma 2 , L 2 tau 1 x tau 2 , L 2 sigma 1 x sigma 2 tau 1 xtau 2 (L x S) 2 tau 1 x tau 2 . The six quadratic L terms are relatively weak, and are chosen in order to make many-body calculations with this operator simpler. (orig.)

    Full Text Available Today, phenomenology, with an emphasis on direct explanations with regard to the lived experience of people is interest of different areas. With emphasis on body, Merleau- Ponty's phenomenology is considered in medical science. In his phenomenology, Merleau- Ponty gives new definition of body and names it lived body. Lived body is against of mechanical body and is the central of subjectivity and being- in- the – world and included all of existential aspects of man. Such definition enable doctors to consider all of existential aspects of man besides his physiological and same understanding of the disease based on the patient lived experience. This paper attempts to examine the implications of this new concept of the body as it is described in the medical field.

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

    In four-generation models Higgs masses of 115-315 GeV are perfectly allowed by electroweak precision data. In this mass range we find dramatic effects on Higgs phenomenology at hadron colliders: production rates are enhanced, weak-boson-fusion channels are suppressed, angular distributions are modified, Higgs pairs can be observed, and Higgs decays to Majorana neutrinos can lead to exotic signals.

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

    Science.gov (United States)

    Brown, S R

    2000-12-01

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

  2. Supply Chain Coordination under Trade Credit and Quantity Discount with Sales Effort Effects

    Directory of Open Access Journals (Sweden)

    Zhihong Wang

    2018-01-01

    Full Text Available The purpose of this paper is to investigate the role of trade credit and quantity discount in supply chain coordination when the sales effort effect on market demand is considered. In this paper, we consider a two-echelon supply chain consisting of a single retailer ordering a single product from a single manufacturer. Market demand is stochastic and is influenced by retailer sales effort. We formulate an analytical model based on a single trade credit and find that the single trade credit cannot achieve the perfect coordination of the supply chain. Then, we develop a hybrid quantitative analytical model for supply chain coordination by coherently integrating incentives of trade credit and quantity discount with sales effort effects. The results demonstrate that, providing that the discount rate satisfies certain conditions, the proposed hybrid model combining trade credit and quantity discount will be able to effectively coordinate the supply chain by motivating retailers to exert their sales effort and increase product order quantity. Furthermore, the hybrid quantitative analytical model can provide great flexibility in coordinating the supply chain to achieve an optimal situation through the adjustment of relevant parameters to resolve conflict of interests from different supply chain members. Numerical examples are provided to demonstrate the effectiveness of the hybrid model.

  3. Aerodynamic Effects in Weakly Ionized Gas: Phenomenology and Applications

    International Nuclear Information System (INIS)

    Popovic, S.; Vuskovic, L.

    2006-01-01

    Aerodynamic effects in ionized gases, often neglected phenomena, have been subject of a renewed interest in recent years. After a brief historical account, we discuss a selected number of effects and unresolved problems that appear to be relevant in both aeronautic and propulsion applications in subsonic, supersonic, and hypersonic flow. Interaction between acoustic shock waves and weakly ionized gas is manifested either as plasma-induced shock wave dispersion and acceleration or as shock-wave induced double electric layer in the plasma, followed by the localized increase of the average electron energy and density, as well as enhancement of optical emission. We describe the phenomenology of these effects and discuss several experiments that still do not have an adequate interpretation. Critical for application of aerodynamic effects is the energy deposition into the flow. We classify and discuss some proposed wall-free generation schemes with respect to the efficiency of energy deposition and overall generation of the aerodynamic body force

  5. The problem of arriving at a phenomenological description of memory loss.

    Science.gov (United States)

    Moyle, W; Clinton, M

    1997-07-01

    This paper discusses a methodological difficulty that arose when uncovering the conscious experience of being nurtured as an in-patient with depression on a psychiatric ward. It considers the problem of arriving at a phenomenological description of memory loss in a patient who had undergone electroconvulsive therapy (ECT). The paper begins by describing the prevalence of depression and its significance for nurses working in in-patient settings. Examples of empirical research into memory loss in depression are used to show what researchers must set aside if they are to arrive at a phenomenological description of memory loss. The choice of a phenomenological approach to the wider study from which the methodological problem discussed here arose is then justified. The phenomena of memory is introduced to show the methodological significance of attempting to arrive at a phenomenological description of the statement made by one of the participants, a woman being treated as an in-patient for major depression. A possible description of the phenomena of memory loss based on the existential phenomenology of Sartre is offered to call into question the ability of researchers to bracket their assumptions. The significance for nurses of the wider study from which our example is taken is then described. Finally it is argued that despite the methodological difficulty described, a phenomenological perspective based on the philosophy of Husserl can point nurses in the direction of meeting the human needs of their patients.

  6. 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.

    Poenaru, D N; Gherghescu, R A; Nagame, Y; Hamilton, J H; Ramayya, A V

    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.

    Strandmark, Margaretha

    2015-08-01

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

  9. Management of Water Quantity and Quality Based on Copula for a Tributary to Miyun Reservoir, Beijing

    2017-12-01

    Due to the complex mutual influence between water quantity and water quality of river, it is difficult to reflect the actual characters of the tributaries to reservoir. In this study, the acceptable marginal probability distributions for water quantity and quality of reservoir inflow were calculated. A bivariate Archimedean copula was further applied to establish the joint distribution function of them. Then multiple combination scenarios of water quantity and water quality were designed to analyze their coexistence relationship and reservoir management strategies. Taking Bai river, an important tributary into the Miyun Reservoir, as a study case. The results showed that it is feasible to apply Frank copula function to describe the jointed distribution function of water quality and water quantity for Bai river. Furthermore, the monitoring of TP concentration needs to be strengthen in Bai river. This methodology can be extended to larger dimensions and is transferable to other reservoirs via establishment of models with relevant data for a particular area. Our findings help better analyzing the coexistence relationship and influence degree of the water quantity and quality of the tributary to reservoir for the purpose of water resources protection.

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

    Science.gov (United States)

    van Hezewijk, René; Stam, Henderikus J

    2008-08-01

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

    One of the central problems of string-phenomenology is to find stable vacua in the four dimensional effective theories which result from compactification. We present an algorithmic method to find all of the vacua of any given string-phenomenological system in a huge class. In particular, this paper reviews and then extends hep-th/0606122 to include various nonperturbative effects. These include gaugino condensation and instantonic contributions to the superpotential.

  14. Phenomenological Equations Relating Various Critical Anomalies above a Cubic-to-Tetragonal Phase Transition Point

    1980-01-01

    Phenomenological equations are derived which interrelate the anomalies in various thermodynamic quantities above the transition point of a cubic-to-tetragonal phase transition caused by an instability of a triply degenerate soft mode. The anomalous part of the Gibbs free energy is assumed to be a simple sum of the three parts which represent the contributions from the three fluctuation components. A cylindrical approximation is adopted to each of the three contributions by taking into account the symmetry of the fluctuations. The theory predicts that the adiabatic elastic compliances, s11s, s12s, and also s11s-s12s should exhibit anomalies proportional to the anomaly in the specific heat at constant pressure. This is in marked contrast with the result of the generalized Pippard equations derived by Garland, and by Janovec. The new equations are successfully tested for KMnF3, CsPbCl3, and CsPbBr3. The β-γ transition of NH4Br is also discussed.

  15. Using Transcendental Phenomenology to Explore the “Ripple Effect” in a Leadership Mentoring Program

    Directory of Open Access Journals (Sweden)

    Tammy Moerer-Urdahl

    2004-06-01

    Full Text Available Several approaches exist for organizing and analyzing data in a phenomenological qualitative study. Transcendental phenomenology, based on principles identified by Husserl (1931 and translated into a qualitative method by Moustakas (1994, holds promise as a viable procedure for phenomenological research. However, to best understand the approach to transcendental phenomenology, the procedures need to be illustrated by a qualitative study that employs this approach. This article first discusses the procedures for organizing and analyzing data according to Moustakas (1994. Then it illustrates each step in the data analysis procedure of transcendental phenomenology using a study of reinvestment or the “ripple effect” for nine individuals who have participated in a youth leadership mentoring program from the 1970s to the present. Transcendental phenomenology works well for this study as this methodology provides logical, systematic, and coherent design elements that lead to an essential description of the experience.

  16. Phenomenology and Qualitative Data Analysis Software (QDAS: A Careful Reconciliation

    Directory of Open Access Journals (Sweden)

    Brian Kelleher Sohn

    2017-01-01

    Full Text Available An oft-cited phenomenological methodologist, Max VAN MANEN (2014, claims that qualitative data analysis software (QDAS is not an appropriate tool for phenomenological research. Yet phenomenologists rarely describe how phenomenology is to be done: pencil, paper, computer? DAVIDSON and DI GREGORIO (2011 urge QDAS contrarians such as VAN MANEN to get over their methodological loyalties and join the digital world, claiming that all qualitative researchers, whatever their methodology, perform processes aided by QDAS: disaggregation and recontextualization of texts. Other phenomenologists exemplify DAVIDSON and DI GREGORIO's observation that arguments against QDAS often identify problems more closely related to the researchers than QDAS. But the concerns about technology of McLUHAN (2003 [1964], HEIDEGGER (2008 [1977], and FLUSSER (2013 cannot be ignored. In this conceptual article I answer the questions of phenomenologists and the call of QDAS methodologists to describe how I used QDAS to carry out a phenomenological study in order to guide others who choose to reconcile the use of software to assist their research.

    Objective: aiming at contributing to the knowledge on doses in computed tomography (CT), this study has the objective of determining dosimetric quantities associated with pediatric abdominal CT scans, comparing the data with diagnostic reference levels (DRL). Materials and methods: the study was developed with a Toshiba Asteion single-slice CT scanner and a GE BrightSpeed multi-slice CT unit in two hospitals. Measurements were performed with a pencil-type ionization chamber and a 16 cm-diameter polymethylmethacrylate trunk phantom. Results: No significant difference was observed in the values for weighted air kerma index (C{sub W}), but the differences were relevant in values for volumetric air kerma index (C{sub VOL}), air kerma-length product (P{sub KL,CT}) and effective dose. Conclusion: Only the CW values were lower than the DRL, suggesting that dose optimization might not be necessary. However, P{sub KL,CT} and effective dose values stressed that there still is room for reducing pediatric radiation doses. The present study emphasizes the importance of determining all dosimetric quantities associated with CT scans. (author)

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

    Luchetti, Martina; Sutin, Angelina R

    2018-01-01

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

    1980-01-01

    This report supersedes ICRU Report 19. Since ICRU Report 19 was published, a number of discussions have taken place between members of the Report Committee on Fundamental Quantities and Units and other workers in the field. Some of these discussions have resulted in the acceptance of certain modifications in the material set out in Report 19 and these modifications are incorporated in the current report. In addition, there has been some expansion and rearrangement of the material in the earlier report. In line, with providing more didactic material and useful source material for other ICRU reports, the general considerations in subsection 1.A of Report 19 have been expanded and placed in a separate subsection. The additional material includes discussions of four terms that are used in this document - quantity, unit, stochastic, and non-stochastic - along with a brief discussion of the mathematical formalism used in ICRU reports. As in ICRU Report 19, the definitions of quantities and units specifically designed for radiation protection (Part B) are separated from those of the general quantities (Part A). The inclusion of the index concept outlined in ICRU Report 25[4] required an extension of Part B

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

    Science.gov (United States)

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

    2017-07-01

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

    During Edmund Husserl,s lifetime, modern logic and mathematics rapidly developed toward their current outlook and Husserl,s writings can be fruitfully compared and contrasted with both 19th century figures (Boole, Schroder, Weierstrass) as well as the 20th century characters (Heyting, Zermelo, Godel). 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.

    We discuss in this paper the metrological status of unmeasurable protection quantities and the need to maintain these kind of quantities in the system. The discussion is based on reports from the institutions responsible for the quantities and on scientific publications. In conclusion, we can say that there are alternatives for changing the system in a way that it keep just measurable quantities, nevertheless the present system is well assimilated. Even though a proposal yet to be presented for changing the system, although might simplify and improve it, is not intended to overcome the existence of unmeasurable quantities or the two kinds of quantities.

    2012-01-01

    The very precise combined HERA data provides a testing ground in which the relevance of novel QCD regimes, other than the successful linear DGLAP evolution, in small-x inclusive DIS data can be ascertained. We present a study of the dependence of the AAMQS fits, based on the running coupling BK non-linear evolution equations (rcBK), on the fitted dataset. This allows for the identification of the kinematical region where rcBK accurately describes the data, and thus for the determination of its applicability boundary. We compare the rcBK results with NNLO DGLAP fits, obtained with the NNPDF methodology with analogous kinematical cuts. Further, we explore the impact on LHC phenomenology of applying stringent kinematical cuts to the low-x HERA data in a DGLAP fit.

    Science.gov (United States)

    Thoma, Samuel

    2012-11-01

    This article tries to link the present lack of theoretical discussion within German Social Psychiatry with a loss of phenomenological and anthropological thought. The so-called Phenomenological Psychiatry used to play a very important role in German psychiatry during the 50 ies until the 70 ies and had strong influences on the first reformers of German psychiatry, such as Walter Ritter von Baeyer, Heinz Häfner, Caspar Kulenkampff, Karl Peter Kisker and Erich Wulff. Their reforms were not only founded by a social criticism put forth by theories such as marxism (Basaglia, Wulff) or structuralism (Foucault) but also by a concrete notion of what it is like to suffer from mental illness and what kind of needs are linked to such suffering. This very notion was given by the phenomenological approach. Finally the article tries to give reasons for today's reciprocal loss of connection of the phenomenological and the socio-psychiatric school. © Georg Thieme Verlag KG Stuttgart · New York.

  15. Terms and definitions in the field of radiological technique. Dose quantities and units

    International Nuclear Information System (INIS)

    1985-12-01

    The standard gives the terms and definitions of concepts, dose quantities and units. The radiation field condition 'secondary electron equilibrium', which forms part of the definition of standard ion dose, is given more precisely. The term 'free in air' is used in its original meaning, i.e. characterization of measuring conditions excluding avoidable stray radiation, which deviates from DIN 6814, part 3/06.72. Dosemeters for measurement of standard ion dose of air kerma are calibrated 'free in air', but this calibration condition is not part of the quantity definition. The quantities standard ion dose or air kerma therefore can also be measured in any other material. The qunatitative relationships between standard ion dose and the quantities 'exposure' and air kerma, as given in the ICRU publication 33 'Quantities and Units' (1980), are explained. The standard introduces the SI units Gray (for energy dose), Sievert (for dose equivalent), and Becquerel (for the activity of a radioactive substance). As the change to the SI units conceals the approximated equality of the numerical values of the standrd ion dose of photon radiation in roentgen, of the energy dose for soft tissue in rad, and of the dose equivalent in rem, new definitions are given in accordance with ICRU 33 for the quantities specified dose rate, dose rate constant, and area exposure product. These definitions use the terms 'energy dose' and 'kerma'. The dose concepts applied in the field of radiation protection, especially ambient dose and individual dose, are defined as dose equivalents in compliance with the Radiation Protection Ordinance. The relevant sections present information on the conversion of standard ion dose values to the corresponding values of kerma, energy dose, or dose equivalent. (orig./HP) [de

    Peccei, R.D.

    1987-01-01

    The author briefly discusses two new phenomena of recent interest, the 5/sup th/ force and variant axions. The former, for its elucidation, will require further gravitational experiments, but the author concludes that variant axions are now definitely rules out experimentally. Various aspects of superstring phenomenology are then addressed, including some of the generic predictions of superstrings and some of its generic problems. In particular, he discusses some of the phenomenological consequences of having an extra Z 0 boson and the circumstances under which this excitation is a genuine prediction of superstrings. Since it is likely that a more reliable relic of superstrings will be provided by the presence of superpartners at low energy (≤ TeV), he discusses some of the bounds for squarks and gluinos obtained at the SppS collider and the expectations for their production at the Tevatron. As a final topic, he touches upon some of the consequences that result from having the Fermi scale arise from an underlying theory. Some aspects of the composite Higgs model and of the strongly coupled standard model are briefly reviewed

  20. A phenomenological model for pre-stressed piezoelectric ceramic stack actuators

    International Nuclear Information System (INIS)

    Wang, D H; Zhu, W

    2011-01-01

    In order to characterize the hysteretic characteristics between the output displacement and applied voltage of pre-stressed piezoelectric ceramic stack actuators (PCSAs), this paper considers that a linear force and a hysteretic force will be generated by a linear extension and a hysteretic extension, respectively, due to the applied voltage to a pre-stressed PCSA and the total force will result in the forced vibration of the single-degree-of-freedom (DOF) system composed of the mass of the pre-stressed PCSA and the equivalent spring and damper of the pre-stressed mechanism, which lets the PCSA be pre-stressed to endure enough tension. On this basis, the phenomenological model to characterize the hysteretic behavior of the pre-stressed PCSA is put forward by using the Bouc–Wen hysteresis operator to model the hysteretic extension. The parameter identification method in a least-squares sense is established by identifying the parameters for the linear and hysteretic components separately with the step and periodic responses of the pre-stressed PCSA, respectively. The performance of the proposed phenomenological model with the corresponding parameter identification method is experimentally verified by the established experimental set-up. The research results show that the phenomenological model for the pre-stressed PCSA with the corresponding parameter identification method can accurately portray the hysteretic characteristics of the pre-stressed PCSA. In addition, the phenomenological model for PCSAs can be deduced from the phenomenological model for pre-stressed PCSAs by removing the terms related to the pre-stressed mechanisms

    Directory of Open Access Journals (Sweden)

    Heather Hill-Vásquez

    2016-06-01

    Full Text Available Focusing on the pain experience of hysterectomy, this article applies and interrogates the foundational descriptive process on which phenomenology is based and suggests that feminism and phenomenology are more compatible than previously asserted. Building upon the work of feminist philosophers who have also explored how feminist and phenomenological approaches share similar methods and intentions—especially in connection with the former’s significant attention to lived experience as a source for the theory feminism employs—the article engages with the philosophies of Maurice Merleau-Ponty and Samuel Mallin who maintain a consistent attention to the body in their phenomenological approaches. Arguing that Mallin’s method of “body hermeneutics” is especially valuable for constructing a feminist phenomenological approach, the article applies Mallin’s theories to the hysterectomy experience, thus revealing how other female-coded experiences of pain, intrusion, shame, and vulnerability are intertwined with hysterectomy. Moreover, the article posits the pain experience of hysterectomy as a particularly emphatic form of phenomenological excorporation in which hidden and habituated assumptions—in this case, the previously unnoticed and unexamined association of a woman’s womb with what it means to be a woman—are painfully brought to light. As the womb becomes more present in the notion and reality of its absence, what does this mean for the many women who experience the shared phenomenon of hysterectomy—including feminist women who enter the experience with a more explicit understanding of themselves as gendered subjects?

    For the description of hadrons as bound states the physical perturbation theory (PPT) on the spatial components of the gluon field over the exact solution, defined by the temporal one, is proposed. A quntization method is used, which in each order of the PPT is relativistic-covariant, and an elimination of the infrared divergences with the help of the phenomenological redefinition of the Coulomb potential. The main elements of the PPT: the Green functions of quarks and gluons, the effective coupling constant are found; and the functional, unifying the meson spectroscopy, dual amplitudes and chiral Lagrangians, is constructed

  7. Relevance in the science classroom: A multidimensional analysis

    Science.gov (United States)

    Hartwell, Matthew F.

    While perceived relevance is considered a fundamental component of adaptive learning, the experience of relevance and its conceptual definition have not been well described. The mixed-methods research presented in this dissertation aimed to clarify the conceptual meaning of relevance by focusing on its phenomenological experience from the students' perspective. Following a critical literature review, I propose an identity-based model of perceived relevance that includes three components: a contextual target, an identity target, and a connection type, or lens. An empirical investigation of this model that consisted of two general phases was implemented in four 9th grade-biology classrooms. Participants in Phase 1 (N = 118) completed a series of four open-ended writing activities focused on eliciting perceived personal connections to academic content. Exploratory qualitative content analysis of a 25% random sample of the student responses was used to identify the main meaning-units of the proposed model as well as different dimensions of student relevance perceptions. These meaning-units and dimensions provided the basis for the construction of a conceptual mapping sentence capturing students' perceived relevance, which was then applied in a confirmatory analysis to all other student responses. Participants in Phase 2 (N = 139) completed a closed survey designed based on the mapping sentence to assess their perceived relevance of a biology unit. The survey also included scales assessing other domain-level motivational processes. Exploratory factor analysis and non-metric multidimensional scaling indicated a coherent conceptual structure, which included a primary interpretive relevance dimension. Comparison of the conceptual structure across various groups (randomly-split sample, gender, academic level, domain-general motivational profiles) provided support for its ubiquity and insight into variation in the experience of perceived relevance among students of different

    2018-01-01

    In some quarters within philosophy of medicine, more particularly in the phenomenological approaches, naturalism is looked upon with suspicion. This paper argues, first, that it is necessary to distinguish between two expressions of this attitude towards naturalism: phenomenological approaches to illness disagree with naturalism regarding various theoretical claims and they disapprove of naturalism on an ethical level. Second, this paper argues that both the disagreement with and the disappro...

    This article examines the history of the conceptualization of dissociative, conversion, and somatoform syndromes in relation to one another, chronicles efforts to classify these and other phenomenologically-related psychopathology in the American diagnostic system for mental disorders, and traces the subsequent divergence in opinions of dissenting sectors on classification of these disorders. This article then considers the extensive phenomenological overlap across these disorders in empirical research, and from this foundation presents a new model for the conceptualization of these disorders. The classification of disorders formerly known as hysteria and phenomenologically-related syndromes has long been contentious and unsettled. Examination of the long history of the conceptual difficulties, which remain inherent in existing classification schemes for these disorders, can help to address the continuing controversy. This review clarifies the need for a major conceptual revision of the current classification of these disorders. A new phenomenologically-based classification scheme for these disorders is proposed that is more compatible with the agnostic and atheoretical approach to diagnosis of mental disorders used by the current classification system.

    2015-01-01

    Thermodynamic quantities of 46 Ti have been calculated in the framework of the BCS model with inclusion of modified nuclear pairing gap (MPBCS) that was proposed in our previous publication. Using modified paring gap results in an S-shaped heat capacity curve at critical temperature with a smooth behavior instead of singular behavior of the same curve in the BCS calculations. In addition the thermal quantities have been extracted within the framework of a canonical ensemble according to the new experimental data on nuclear level densities measured by the Oslo group. Comparison shows a good agreement between our calculations in MPBCS and the extracted quantities in the canonical ensemble framework

    2017-09-01

    The activation response of a material is a primary factor considered when evaluating its suitability for a nuclear application. Various radiological quantities, such as total (becquerel) activity, decay heat, and γ dose, can be readily predicted via inventory simulations, which numerically evolve in time the composition of a material under exposure to neutron irradiation. However, the resulting data sets can be very complex, often necessarily resulting in an over-simplification of the results - most commonly by just considering total response metrics. A number of different techniques for disseminating more completely the vast amount of data output from, in particular, the FISPACT-II inventory code system, including importance diagrams, nuclide maps, and primary knock-on atom (PKA) spectra, have been developed and used in scoping studies to produce database reports for the periodic table of elements. This paper introduces the latest addition to this arsenal - standardised and automated plotting of the time evolution in a radiological quantity for a given material separated by contributions from dominant radionuclides. Examples for relevant materials under predicted fusion reactor conditions, and for bench-marking studies against decay-heat measurements, demonstrate the usefulness and power of these radionuclide-separated activation plots.

  16. The damping of spin motions in ultrathin films: Is the Landau-Lifschitz-Gilbert phenomenology applicable?

    International Nuclear Information System (INIS)

    Mills, D.L.; Arias, Rodrigo

    2006-01-01

    The Landau-Lifschitz-Gilbert (LLG) equation is used widely in device design to describe spin motions in magnetic nanoscale structures. The damping term in this equation plays an essential role in the description of the magnetization dynamics. The form of this term is simple and appealing, but it is derived through use of elementary phenomenological considerations. An important question is whether or not it provides a proper description of the damping of the magnetization in real materials. Recently, it was predicted that a mechanism called two magnon damping should contribute importantly to linewidths and consequently spin damping in ultrathin ferromagnetic films. This process yields ferromagnetic resonance (FMR) linewidths whose frequency dependence is incompatible with the linear variation expected from the Landau-Lifschitz equation. This prediction has now been confirmed experimentally. Furthermore, subsequent experimental and theoretical studies have demonstrated that the damping rate depends strongly on wave vector as well. It is thus clear that for many samples, the LLG equation fails to account for the systematics of the damping of the magnetization in ultrathin ferromagnets, at the linear response level. The paper will review the recent literature on this topic relevant to this issue. One must then inquire into the nature of a proper phenomenology to describe these materials. At the linear response level, the theory of the two magnon mechanism is sufficiently complete that one can describe the response of these systems without resort to LLG phenomenology. However, currently there is very great interest in the large amplitude response of the magnetization in magnetic nanostructures. In the view of the authors, it is difficult to envision a generally applicable extension of linear response theory into the large amplitude regime

    International Nuclear Information System (INIS)

    1989-01-01

    It is recommended that if measurements are made with the objective of monitor radiation levels in the environment to elucidate long-term changes in these levels, then air kerma should be used. If the objective is to give an indication that levels from man-made sources are acceptable within specified limits for the exposure of people, then ambient dose equivalent should be used. It should be noted that radiation risks to individuals are best expressed by the quantity effective dose equivalent. If this latter quantity is to be accurately assessed, it may be necessary to obtain details of the quality of the environmental radiation that cannot be described adequately by simple measurements of either air kerma or ambient dose equivalent. If the above objectives pertain, the measurements should record both air kerma and ambient dose equivalent. If neutrons are measured in the environment then ambient dose equivalent is the appropriate quantity for both the above objectives. (author)

    2016-01-01

    The emergence of Phenomenology cannot to be understood outside the context of naturalism, the crisis affecting the philosophy and the scientific foundation of psychology toward the end of the 19th century. Binswanger thinks Husserl's attempt to found the experience of the things themselves in intentional living structures can to be useful to guide the psychiatric examination. For that, he seeks in the fundamental dimensions of existence, the conditions of possibility of being sick, which are also those of the same psychiatry. While the phenomenological psycho(patho)logy has not born of direct confrontation with patients, it doesn't mean that it doesn't have internal references with practice. It's proposed then a semiological Eidetic founded in multiple modes of intentionality, or "basic categories", opposite of semiology supported on psychic functions. From etiology to the anthropological a priori of mental illnesses, from the symptom to the phenomenon, here are two possible readings in the field of the clinic.

  1. Phenomenological study on the significance of the scalar potential and Lamb shift

    International Nuclear Information System (INIS)

    Yuan Xuhao; Li Xueqian; Ke Hongwei

    2011-01-01

    We indicated in our previous work that for QED the contributions of the scalar potential, which appears at the loop level, is much smaller than that of the vector potential, and in fact negligible. But the situation may be different for QCD, the reason being that the loop effects are more significant because α s is much larger than α, and secondly the non-perturbative QCD effects may induce the scalar potential. In this work, we phenomenologically study the contribution of the scalar potential to the spectra of charmonium. Taking into account both vector and scalar potentials, by fitting the well measured charmonium spectra, we re-fix the relevant parameters and test them by calculating other states of the charmonium family. We also consider the role of the Lamb shift and present the numerical results with and without involving the Lamb shift. (authors)

    Full Text Available Healthcare professionals, daily confronted with existential failty, feel themselves emotionally vulnerable too. For this reason, they need knowledge and tools in order to take care for themselves. Phenomenology provides an epistemological model that includes subjective and affective dimensions and legitimates lived experience as a source of cognition. In the undergraduate and continuing education of healthcare professionals, the phenomenological approach can represent a way of promoting self-care through personal narrative and reflection.

  6. Phenomenological perspectives on self-care in aging.

    2013-01-01

    Self-care is a central concept in health care and may be considered as a means to maintain, restore, and improve one's health and well-being. When performed effectively, self-care contributes not only to human functioning but also to human structural integrity and human development (ie, to a dynamic and holistic state of health). Self-care as a clinical concept is relevant for health care professionals, and it should be meaningful to investigate it at a philosophical level and to further elaborate upon this concept. The aim of this article is to discuss and elaborate upon a phenomenological perspective on self-care in aging that is relevant for the health sciences. Self-care may be preliminarily regarded as a fundamental perspective for the conscious older individual, and as a way of being in the world with both the objective body and with the lived body. The lived body is the personal center of perception and the field of action, and it is also the center of self-care. The potentiality or ability for self-care activity and self-care activity itself are structures given to perception, with self-care ability as an integral part of the lived body. The actualization of self-care ability comes about through a certain meaning, which can be regarded as an important driving force. It is constituted by communication, a healthy lifestyle, and by building meaning and socializing. Successful self-care involves having contacts with the health care system, being conscious of a sound lifestyle, being physically and mentally active, being engaged, having social contacts with family and others, as well as being satisfied, positive, and being able to look forward. One fundamental cornerstone is serenity on behalf of the individual. Self-care can facilitate transitions, and it may also be an outcome of transitions.

    To determine the quantity of potential heat W that has flowed past a certain point in a certain time, the velocity of the combustible Q, the temperature T, and the specific gravity YDTU are measured, and these values are transmitted to a computer which automatically calculates the quantity: ..pi..EQUATION/sup -/ in which delta T is the difference between the combustible temperature T and a reference temperature, and in which the relation f(YDTU, delta T) represents the heat of combustion as a function of the quantities YDTU and delta T and possibly other properties of the combustible. Alternatively the quantity: ..pi..EQUATION/sup -/ may be measured; here the quantities have the same meaning as above.

    Highlights: ► Assessment of CHF limits is vital for LWR optimization and safety analysis. ► Phenomenological modeling is a valuable adjunct to pure empiricism. ► It is based on empirical representations of the (several, competing) phenomena. ► Phenomenological modeling codes making ‘aggregate’ predictions need careful assessment against experiments. ► The physical and mathematical basis of a phenomenological modeling code GRAMP is presented. ► The GRAMP code is assessed against measurements from BARC (India) and Harwell (UK), and the Look Up Tables. - Abstract: Reliable knowledge of the critical heat flux is vital for the design of light water reactors, for both safety and optimization. The use of wholly empirical correlations, or equivalently “Look Up Tables”, can be very effective, but is generally less so in more complex cases, and in particular cases where the heat flux is axially non-uniform. Phenomenological models are in principle more able to take into account of a wider range of conditions, with a less comprehensive coverage of experimental measurements. These models themselves are in part based upon empirical correlations, albeit of the more fundamental individual phenomena occurring, rather than the aggregate behaviour, and as such they too require experimental validation. In this paper we present the basis of a general-purpose phenomenological code, GRAMP, and then use two independent ‘direct’ sets of measurement, from BARC in India and from Harwell in the United Kingdom, and the large dataset embodied in the Look Up Tables, to perform a validation exercise on it. Very good agreement between predictions and experimental measurements is observed, adding to the confidence with which the phenomenological model can be used. Remaining important uncertainties in the phenomenological modeling of CHF, namely the importance of the initial entrained fraction on entry to annular flow, and the influence of the heat flux on entrainment rate

    Science.gov (United States)

    Eder, W. E.

    1982-01-01

    Properties of the quantity "plane angle" are explored under the hypothesis that it is a dimensional quantity. The exploration proceeds especially with respect to the physical concept, its mathematical treatment, vector concepts, measurement theory, units of related quantities, engineering pragmatism, and SI. An attempt is made to bring these different relations into a rational, logical and consistent framework, and thus to justify the hypothesis. Various types of vectorial quantities are recognized, and their properties described with an outline of the necessary algebraic manipulations. The concept of plane angle is amplified, and its interdependence with the circular arc is explored. The resulting units of plane angle form a class of similar scales of measurement. Consequences of the confirmed hypothesis are developed for mathematical expressions involving trigonometric functions, rotational volumes and areas, mathematical limits, differentiation and series expansion. Consequences for mechanical rotational quantities are developed, with proposals for revisions to a number of expressions for derived units within SI. A revised definition for the quantity "plane angle" is stated to take account of the developed insights. There is a clear need to reconsider the status of plane angle and some other quantities within the international framework of SI.

    To describe van Manen's method and concept of reduction in a study that used a phenomenological hermeneutic approach. Nurse researchers have used van Manen's method in different ways. Participants' lifeworlds are described in depth, but descriptions of reduction have been brief. The literature and knowledge review and manual search of research articles. Databases Web Science, PubMed, CINAHL and PsycINFO, without applying a time period, to identify uses of van Manen's method. This paper shows how van Manen's method has been used in nursing research and gives some examples of van Manen's reduction. Reduction enables us to conduct in-depth phenomenological hermeneutic research and understand people's lifeworlds. As there are many variations in adapting reduction, it is complex and confusing. This paper contributes to the discussion of phenomenology, hermeneutic study and reduction. It opens up reduction as a method for researchers to exploit.

It is shown that there are essentially three types of colour models with colour excitation when the colour group is SU(3)- Han-Nambu, Greenberg and a model which has the same charges as that of Tati and which can be thought of as the Gell-Mann colour scheme with excitation of the colour degrees of freedom. Particular attention is paid to the four problems of colour models for psi phenomenology-the radiative decays, the G parity conservation, the lack of deep inelastic threshold phenomena and the apparent discovery of dileptons at SPEAR.

  19. The phenomenology of lucid dreaming: an online survey.

    Stumbrys, Tadas; Erlacher, Daniel; Johnson, Miriam; Schredl, Michael

    2014-01-01

    In lucid dreams the dreamer is aware that he or she is dreaming. Although such dreams are not that uncommon, many aspects of lucid dream phenomenology are still unclear. An online survey was conducted to gather data about lucid dream origination, duration, active or passive participation in the dream, planned actions for lucid dreams, and other phenomenological aspects. Among the 684 respondents who filled out the questionnaire, there were 571 lucid dreamers (83.5%). According to their reports, lucid dreams most often originate spontaneously in adolescence. The average lucid dream duration is about 14 minutes. Lucid dreamers are likely to be active in their lucid dreams and plan to accomplish different actions (e.g., flying, talking with dream characters, or having sex), yet they are not always able to remember or successfully execute their intentions (most often because of awakening or hindrances in the dream environment). The frequency of lucid dream experience was the strongest predictor of lucid dream phenomenology, but some differences were also observed in relation to age, gender, or whether the person is a natural or self-trained lucid dreamer. The findings are discussed in light of lucid dream research, and suggestions for future studies are provided.

  20. An integrated approach to determine phenomenological equations in metallic systems

    Science.gov (United States)

    Ghamarian, Iman

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

    While mainstream psychiatry tends to view psychosis as an enduring and chronic condition, there is growing interest in the possibility of recovery from psychosis. A phenomenological research method was utilized in interviewing 17 individuals who all self-identified as being in recovery from psychosis. The research question was, "What was the lived…

  3. Duty and “the just” in the phenomenological ethics: towards a material deontological ethics

    Directory of Open Access Journals (Sweden)

    Pilar Fernández Beites

    2017-10-01

    Full Text Available This article defends that ethics of values developed from classical phenomenology includes an interesting theory of duty. Developing some thesis of Max Scheler, here it is proposed a phenomenological notion of “duty” (or “the right”, if we use the term of Ross, which is linked to a very peculiar value: the value of “justice”. This allows to keep away the phenomenological ethics of values of all kinds of “consequentialism” and bring it closer to the “deontological” ethics. But the duty of phenomenological ethics is not formal, but founded on the value, so that we could speak of an “material deontological ethics”, which aims to serve as a mediation between the two great classical paradigms.

    Full Text Available We carried out a phenomenological and narrative analysis of the journals of writer Alejandra Pizarnik. We analyzed descriptions of her experiences as a psychiatric patient, and the changes reported in her physical experiences as well as existential orientation. This is an inductive enquiry based on the phenomenological and narrative analysis of a historic case study. Based on our results, we suggest some phenomenological categories which might be vital to our understanding of certain mental illness pathologies.

  6. Phenomenology of muon number violation in spontaneously broken gauge theories

    International Nuclear Information System (INIS)

    Shanker, O.U.

    1980-01-01

    The phenomenology of muon number violation in gauge theories of weak and electromagnetic interactions is studied. In the first chapter a brief introduction to the concept of muon number and to spontaneously broken gauge theories is given. A review of the phenomenology and experimental situation regarding different muon number violating processes is made in the second chapter. A detailed phenomenological study of the μe conversion process μ - + (A,Z) → e - + (A,Z) is given in the third chapter. In the fourth chapter some specific gauge theories incorporating spontaneously broken horizontal gauge symmetries between different fermion generations are discussed with special reference to muon number violation in the theories. The μe conversion process seems to be a good process to search for muon number violation if it occurs. The K/sub L/-K/sub S/ mass difference is likely to constrain muon number violating rates to lie far below present experimental limits unless strangeness changing neutral currents changing strangeness by two units are suppressed

    2013-10-22

    The theory and phenomenology of neutrinos will be addressed, especially that relating to the observation of neutrino flavor transformations. The current status and implications for future experiments will be discussed with special emphasis on the experiments that will determine the neutrino mass ordering, the dominant flavor content of the neutrino mass eigenstate with the smallest electron neutrino content and the size of CP violation in the neutrino sector. Beyond the neutrino Standard Model, the evidence for and a possible definitive experiment to confirm or refute the existence of light sterile neutrinos will be briefly discussed.

  11. Beyond Empathy. Phenomenological Approaches to Intersubjectivity

    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. 

  12. Particle Phenomenology of Compact Extra Dimensions

    International Nuclear Information System (INIS)

    Melbeus, Henrik

    2012-01-01

    This thesis is an investigation of the subject of extra dimensions in particle physics. In recent years, there has been a large interest in this subject. In particular, a number of models have been suggested that provide solutions to some of the problem with the current Standard Model of particle physics. These models typically give rise to experimental signatures around the TeV energy scale, which means that they could be tested in the next generation of high-energy experiments, such as the LHC. Among the most important of these models are the universal extra dimensions model, the large extra dimensions model by Arkani-Hamed, Dimopolous, and Dvali, and models where right-handed neutrinos propagate in the extra dimensions. In the thesis, we study phenomenological aspects of these models, or simple modifications of them. In particular, we focus on Kaluza-Klein dark matter in universal extra dimensions models, different aspects of neutrino physics in higher dimensions, and collider phenomenology of extra dimensions. In addition, we consider consequences of the enhanced renormalization group running of physical parameters in higher-dimensional models

  13. From the History of Islamic Studies: A.-M. Schimmel and Phenomenological Approach to Religion

    Directory of Open Access Journals (Sweden)

    Samarina Tat’iana

    2017-06-01

    Full Text Available This article analyses key works of the well-known classic of Islamic studies A.-M. Schimmel and demonstrates that in her legacy the methodology of classical phenomenology of religion has found its fresh application to the study of Islam. The article focuses on essential points of A.-M. Schimmel’s biography that had infl uenced her academic career, and then analyses her phenomenological approach showing how she builds a system of description of Islam by means of systematising religious phenomena that proceeds from external forms (material objects to the centre of religion, God. Phenomenological analysis of Islam provides a base for comprehensive understanding and description of religious phenomena, starting from the perception of stone, holiday, clothes, myth in minds of ordinary Muslims. Schimmel’s phenomenological approach to Islam takes into account the specifi city of lived religion prior to the emergence of this trend. A.-M. Schimmel’s legacy therefore fits in the context of contemporary religious studies. The second part of the article examines the influence of leading scholars in phenomenology of religion (Mircea Eliade, Gerardus van der Leeuw, Friedrich Heiler on A.-M. Schimmel. It is concluded that the positive reception of her work among scholars of Islam and among Muslims themselves suggests that the language of the phenomenological description is the language of religious dialogue.

  14. The Logic of Appearance: Dennett, Phenomenology and Psychoanalysis

    Science.gov (United States)

    Feyaerts, Jasper; Vanheule, Stijn

    2017-01-01

    In the present essay, we aim to develop and contrast three different positions toward Sellars’ distinction between the manifest and scientific images of man: Dennett’s philosophical reconstruction of neurocognitive science, contemporary phenomenology and psychoanalysis. We will suggest that these respective traditions and the substantial differences between them can be understood in terms of a ‘logic of appearance.’ Related to this are differing ideas about the rights and limits of the first-person perspective, the relation between conscious experience and belief, and the issue of naturalization. In the final part, we will try to specify, on the basis of a detailed reading of the disagreement between Dennett and phenomenology, in what way psychoanalytic theory could respond to these different issues.

  15. Local Field Response Method Phenomenologically Introducing Spin Correlations

    Science.gov (United States)

    Tomaru, Tatsuya

    2018-03-01

    The local field response (LFR) method is a way of searching for the ground state in a similar manner to quantum annealing. However, the LFR method operates on a classical machine, and quantum effects are introduced through a priori information and through phenomenological means reflecting the states during the computations. The LFR method has been treated with a one-body approximation, and therefore, the effect of entanglement has not been sufficiently taken into account. In this report, spin correlations are phenomenologically introduced as one of the effects of entanglement, by which multiple tunneling at anticrossing points is taken into account. As a result, the accuracy of solutions for a 128-bit system increases by 31% compared with that without spin correlations.

  17. A phenomenological approach to modeling chemical dynamics in nonlinear and two-dimensional spectroscopy.

    Ramasesha, Krupa; De Marco, Luigi; Horning, Andrew D; Mandal, Aritra; Tokmakoff, Andrei

    2012-04-07

    We present an approach for calculating nonlinear spectroscopic observables, which overcomes the approximations inherent to current phenomenological models without requiring the computational cost of performing molecular dynamics simulations. The trajectory mapping method uses the semi-classical approximation to linear and nonlinear response functions, and calculates spectra from trajectories of the system's transition frequencies and transition dipole moments. It rests on identifying dynamical variables important to the problem, treating the dynamics of these variables stochastically, and then generating correlated trajectories of spectroscopic quantities by mapping from the dynamical variables. This approach allows one to describe non-Gaussian dynamics, correlated dynamics between variables of the system, and nonlinear relationships between spectroscopic variables of the system and the bath such as non-Condon effects. We illustrate the approach by applying it to three examples that are often not adequately treated by existing analytical models--the non-Condon effect in the nonlinear infrared spectra of water, non-Gaussian dynamics inherent to strongly hydrogen bonded systems, and chemical exchange processes in barrier crossing reactions. The methods described are generally applicable to nonlinear spectroscopy throughout the optical, infrared and terahertz regions.

  18. Generalized uncertainty principle and quantum gravity phenomenology

    Science.gov (United States)

    Bosso, Pasquale

    The fundamental physical description of Nature is based on two mutually incompatible theories: Quantum Mechanics and General Relativity. Their unification in a theory of Quantum Gravity (QG) remains one of the main challenges of theoretical physics. Quantum Gravity Phenomenology (QGP) studies QG effects in low-energy systems. The basis of one such phenomenological model is the Generalized Uncertainty Principle (GUP), which is a modified Heisenberg uncertainty relation and predicts a deformed canonical commutator. In this thesis, we compute Planck-scale corrections to angular momentum eigenvalues, the hydrogen atom spectrum, the Stern-Gerlach experiment, and the Clebsch-Gordan coefficients. We then rigorously analyze the GUP-perturbed harmonic oscillator and study new coherent and squeezed states. Furthermore, we introduce a scheme for increasing the sensitivity of optomechanical experiments for testing QG effects. Finally, we suggest future projects that may potentially test QG effects in the laboratory.

    2010-01-01

    Introduction: Although a considerable amount of research has addressed psychopathological and personality correlates of creativity, the relationship between these characteristics and the phenomenology of creativity has been neglected. Relating these characteristics to the phenomenology of creativity may assist in clarifying the precise nature of the relationship between psychopathology and creativity. The current article reports on an empirical study of the relationship between the phenomenology of the creative process and psychopathological and personality characteristics in a sample of artists. Method: A total of 100 artists (43 males, 57 females, mean age = 34.69 years) from a range of disciplines completed the Experience of Creativity Questionnaire and measures of “positive” schizotypy, affective disturbance, mental boundaries, and normal personality. Results: The sample of artists was found to be elevated on “positive” schizotypy, unipolar affective disturbance, thin boundaries, and the personality dimensions of Openness to Experience and Neuroticism, compared with norm data. Schizotypy was found to be the strongest predictor of a range of creative experience scales (Distinct Experience, Anxiety, Absorption, Power/Pleasure), suggesting a strong overlap of schizotypal and creative experience. Discussion: These findings indicate that “positive” schizotypy is associated with central features of “flow”-type experience, including distinct shift in phenomenological experience, deep absorption, focus on present experience, and sense of pleasure. The neurologically based construct of latent inhibition may be a mechanism that facilitates entry into flow-type states for schizotypal individuals. This may occur by reduced latent inhibition providing a “fresh” awareness and therefore a greater absorption in present experience, thus leading to flow-type states. PMID:18682376

  1. Is nuclear structure relevant to non-mesonic hyper-nuclear weak decay?

    International Nuclear Information System (INIS)

    2002-01-01

    This work studies the relevance of nuclear structure in the non-mesonic weak decay of Λ-hypernuclei, with the mechanism of ΛN → NN transition being restricted to one pion exchange (OPE) only. As an application, for the hypernucleus Λ 12 C a comparison between the L-S coupling and the j-j coupling gives an estimate of the range of nuclear structure effects. A considerable dependence is found of the total decay rate and the ratio Γ n /Γ p on the single particle properties of nuclear models. The possible contribution from the ΔI = 3/2 channel is investigated in a phenomenological manner. (author)

    Scholars who research phenomena of concern to the discipline of nursing are challenged with making wise choices about different qualitative research approaches. Ultimately, they want to choose an approach that is best suited to answer their research questions. Such choices are predicated on having made distinctions between qualitative methodology, methods, and analytic frames. In this article, we distinguish two qualitative research approaches widely used for descriptive studies: descriptive phenomenological and qualitative description. Providing a clear basis that highlights the distinguishing features and similarities between descriptive phenomenological and qualitative description research will help students and researchers make more informed choices in deciding upon the most appropriate methodology in qualitative research. We orient the reader to distinguishing features and similarities associated with each approach and the kinds of research questions descriptive phenomenological and qualitative description research address. © The Author(s) 2016.

    1998-01-01

    Examples exist in dosimetry and radiation protection where primary attention was focused on the unit rather than the corresponding quantity. Another difficulty arises from the fact that quantities in this field cannot be considered as pure physical quantities, they are rather biophysical quantities. There are too many quantities (e. g. 17 quantities based on the dose equivalent), with differences in numerical values of 'similar' quantities, not always satisfactory approximations of virtually unmeasurable quantities by measurable quantities, inconsistency in definitions and interpretations of quantities of some international expert bodies, and problems of weighting and conversion factors.

    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.

    1985-01-01

    Philosophies and quantities for radiation protection have often been subjected to changes, and some of the developments are traced which ultimately led to recent proposals by ICRU. Development in the past has largely been towards clarification and generalisation of definitions. The present changes, however, reflect a more fundamental issue, the transition from the limitation system to the assessment system in radiation protection. The index quantities were suitable tools to ascertain compliance with the limitation system of radiation protection. The new quantities proposed by ICRU are suitable estimators for effective dose equivalent, which is an essential quantity in the assessment system of radiation protection. A synopsis of the definitions is given. (author)

    2014-01-01

    Highlights: • Phenomenological uncertainty analysis has been applied to level 2 PSA. • The methodology provides an alternative to simple deterministic analyses and sensitivity studies. • A realistic evaluation provides a more complete characterization of risks. • Uncertain parameters of MAAP code for the early containment failure were identified. - Abstract: This paper illustrates an application of a severe accident analysis code, MAAP, to the uncertainty evaluation of early containment failure scenarios employed in the containment event tree (CET) model of a reference plant. An uncertainty analysis of containment pressure behavior during severe accidents has been performed for an optimum assessment of an early containment failure model. The present application is mainly focused on determining an estimate of the containment building pressure load caused by severe accident sequences of a nuclear power plant. Key modeling parameters and phenomenological models employed for the present uncertainty analysis are closely related to the in-vessel hydrogen generation, direct containment heating, and gas combustion. The basic approach of this methodology is to (1) develop severe accident scenarios for which containment pressure loads should be performed based on a level 2 PSA, (2) identify severe accident phenomena relevant to an early containment failure, (3) identify the MAAP input parameters, sensitivity coefficients, and modeling options that describe or influence the early containment failure phenomena, (4) prescribe the likelihood descriptions of the potential range of these parameters, and (5) evaluate the code predictions using a number of random combinations of parameter inputs sampled from the likelihood distributions

    Target restoration space (TRS) is the most precise space required for designing optimal prosthesis. TRS consists of an internal or external tooth space to confirm the esthetics and function of the final restoration. Therefore, assisted with quantitive analysis transfer, TRS quantitative analysis is a significant improvement for minimum tooth preparation. This article presents TRS quantity-related measurement, analysis, transfer, and internal relevance of three TR. classifications. Results reveal the close bond between precision and minimally invasive treatment. This study can be used to improve the comprehension and execution of precise esthetic prosthodontics.

  11. EOQ Model for Deteriorating Items with exponential time dependent Demand Rate under inflation when Supplier Credit Linked to Order Quantity

    Rakesh Prakash Tripathi

    2014-05-01

    Full Text Available In paper (2004 Chang studied an inventory model under a situation in which the supplier provides the purchaser with a permissible delay of payments if the purchaser orders a large quantity. Tripathi (2011 also studied an inventory model with time dependent demand rate under which the supplier provides the purchaser with a permissible delay in payments. This paper is motivated by Chang (2004 and Tripathi (2011 paper extending their model for exponential time dependent demand rate. This study develops an inventory model under which the vendor provides the purchaser with a credit period; if the purchaser orders large quantity. In this chapter, demand rate is taken as exponential time dependent. Shortages are not allowed and effect of the inflation rate has been discussed. We establish an inventory model for deteriorating items if the order quantity is greater than or equal to a predetermined quantity. We then obtain optimal solution for finding optimal order quantity, optimal cycle time and optimal total relevant cost. Numerical examples are given for all different cases. Sensitivity of the variation of different parameters on the optimal solution is also discussed. Mathematica 7 software is used for finding numerical examples.

    Full Text Available This study has tried to investigate and reconstruct the meaning of life style in a phenomenological approach among young people in Tehran city. Most research done on this issue has been described by adopting deductive strategy and underlying prefabricated theories.While the phenomenological method focuses on how humans meant their experiences and transform them to collective and personal form of their consciousness. It also requires a methodologicalunderstandingthat how humans experience these phenomena. Researcher to collect such data is necessary to engage in-depth interviews with people who have directly experienced the phenomenon of interest that means they have Lived experience that is in contrast with second order experience and the operating variables that derived from metanarratives. Thus, we have distinguished four major lifestyles of young people’s lives in Tehran according to Husserl’s epoche manner and meet schutz’s typification criteria that contain; pleasure seeking - aesthetic lifestyle, functionalistic, subcultural and passive.

    Sprenger, Martin; Goethe Univ., Frankfurt am Main; Nicolini, Piero; Bleicher, Marcus

    2012-02-01

    Many modern theories which try to unite gravity with the Standard Model of particle physics, as e.g. string theory, propose two key modifications to the commonly known physical theories: - the existence of additional space dimensions - the existence of a minimal length distance or maximal resolution. While extra dimensions have received a wide coverage in publications over the last ten years (especially due to the prediction of micro black hole production at the LHC), the phenomenology of models with a minimal length is still less investigated. In a summer study project for bachelor students in 2010 we have explored some phenomenological implications of the potential existence of a minimal length. In this paper we review the idea and formalism of a quantum gravity induced minimal length in the generalised uncertainty principle framework as well as in the coherent state approach to non- commutative geometry. These approaches are effective models which can make model-independent predictions for experiments and are ideally suited for phenomenological studies. Pedagogical examples are provided to grasp the effects of a quantum gravity induced minimal length. (orig.)

    This paper deals with the phenomenological consequences of supersymmetric theories, and with the implications of such theories for future high energy machines. The paper represents the work of a subgroup at the meeting. The authors are concerned only with high energy predictions of supersymmetry; low energy consequences (for example in the K/sub o/K-bar/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

    2011-01-01

    JPL collaborated with experts from industry and other organizations to develop a conceptual model of quantities, units, dimensions, and values based on the current work of the ISO 80000 committee revising the International System of Units & Quantities based on the International Vocabulary of Metrology (VIM). By providing support for ISO 80000 in SysML via the International Vocabulary of Metrology (VIM), this conceptual model provides, for the first time, a standard-based approach for addressing issues of unit coherence and dimensional analysis into the practice of systems engineering with SysML-based tools. This conceptual model provides support for two kinds of analyses specified in the International Vocabulary of Metrology (VIM): coherence of units as well as of systems of units, and dimension analysis of systems of quantities. To provide a solid and stable foundation, the model for defining quantities, units, dimensions, and values in SysML is explicitly based on the concepts defined in VIM. At the same time, the model library is designed in such a way that extensions to the ISQ (International System of Quantities) and SI Units (Systeme International d Unites) can be represented, as well as any alternative systems of quantities and units. The model library can be used to support SysML user models in various ways. A simple approach is to define and document libraries of reusable systems of units and quantities for reuse across multiple projects, and to link units and quantity kinds from these libraries to Unit and QuantityKind stereotypes defined in SysML user models.

    This article examines a clinical sample of 66 Dominican and Puerto Rican subjects who reported ataques de nervios and also psychiatric disorder, and disentangles the phenomenological experiences of ataque de nervios, panic attacks, and panic disorder. In-depth cultural interviews assessed the symptomatic phenomenology of ataque episodes from the local perspective as well as in terms of key panic features, such as recurrence, rapid peaking of symptoms, and lack of provocation. Independent diagnostic assessments of panic attacks and disorder were also used to establish the phenomenological overlap between ataque and panic. Our findings indicate that 36 percent of ataques de nervios fulfill criteria for panic attacks and between 17 percent and 33 percent for panic disorder, depending on the overlap method used. The main features distinguishing ataques that fulfill panic criteria from ataques that do not include whether the episodes were provoked by an upsetting event in the person's life and the rapidity of crescendo of the actual attack. A key finding is that ataques often share individual phenomenological features with panic episodes, but that these features usually do not "run together" during the ataque experience. This confirms previous findings that ataque is a more inclusive construct than panic disorder. The importance of these findings for the clinical diagnosis and treatment of persons with ataques is discussed.

  1. Concept of ICRU's operational quantity and its application

    International Nuclear Information System (INIS)

    Murakami, Hiroyuki

    1995-01-01

    The operational quantity which was introduced in the ICRU report 39 published in 1985 was shocking rather than fresh for the author. The report was translated into Japanese, but at the beginning, the contents were not able to be understood. Thereafter, the measurement of ICRU sphere dose equivalent was introduced in a national law. But it is feared that the understanding of this operational quantity is limited to specialist level, and is not by men of practical works. The meaning of ''operational'' must be that workers measure and obtain dose on the spot for the radiation protection for themselves. The principles used when ICRU considered the new practical measured quantity are shown. In the definition of operational quantity in area monitoring, two concepts of expanded and aligned connect real measurement with the operational quantity. The problems of measuring individual dose equivalent are discussed. As to the reality of applying the operational quantity, the fundamentals of the calibration of measuring instruments, the investigation of the operational quantity in relation to measuring instruments and measurement mode, and the relation of area monitoring and individual monitoring are described.

    2018-05-17

    The assessment of marijuana use quantity poses unique challenges. These challenges have limited research efforts on quantity assessments. However, quantity estimates are critical to detecting associations between marijuana use and outcomes. We examined accuracy of marijuana users' estimations of quantities of marijuana they prepared to ingest and predictors of both how much was prepared for a single dose and the degree of (in)accuracy of participants' estimates. We recruited a sample of 128 regular-to-heavy marijuana users for a field study wherein they prepared and estimated quantities of marijuana flower in a joint or a bowl as well as marijuana concentrate using a dab tool. The vast majority of participants overestimated the quantity of marijuana that they used in their preparations. We failed to find robust predictors of estimation accuracy. Self-reported quantity estimates are inaccurate, which has implications for studying the link between quantity and marijuana use outcomes.

  3. Phenomenology of heavy quarkonia and quantum chromodynamics

    International Nuclear Information System (INIS)

    Schmitz, S.J.A.

    1986-01-01

    Heavy quarkonia, the c anti c, b anti b, and soon to be discovered t anti t families of states, are studied in the framework of potential theory. The earlier proposed, flavor independent Riverside potential is fit to masses of c anti c and b anti b states and their electronic widths are calculated. An unusual feature of the potential is the use of a parameter b which controls the small r or asymptotic freedom behavior and which can be related to the QCD scale parameters Λ/MS. This parameter b is virtually undetermined by the c anti c and b anti b spectra, merely excluding the range b < 4 or Λ/MS ≤ 120 MeV and slightly favoring Λ/MS ≅ 250 MeV. It is shown how even minimal information on the t anti t states will restrict the Λ/MS value to a range of the order of 50 MeV. A recent Lattice Gauge potential shows a remarkable closeness to the phenomenological approach. In view of the approximations involved, the difference between the two potentials is small. This difference is investigated in terms of the strong coupling constant α which can be extracted from both potentials. In the main r regime the Lattice Gauge α is markedly smaller than the phenomenological one. It is shown that the absence of intermediate, virtual quark loops in the Lattice Gauge calculation, i.e. the so-called quenched approximation, accounts for at least some and possibly most of that difference. Overall, the phenomenology of heavy quarkonia as studied in this work is in no conflict with QCD

  8. A Phenomenology of ‘Blending in’: Beyond Emotional Regulation

    Directory of Open Access Journals (Sweden)

    Katie Creighton

    2018-02-01

    Full Text Available The phenomenon of devaluing of self for adolescent girls has been highlighted in previous qualitative research in a US cultural context. Carol Gilligan and her colleagues have documented a loss of connection to self and loss of voice. ‘Blending in’ pertains to such a loss of connection and voice. ‘Blending in’ emerges from many aspects of 8 Irish females’ retrospective qualitative phenomenological accounts of their adolescent experiences. These features of blending in include: a dumbing down of intellectual ability in order to fit in, a desire to be hidden in the group to ‘fade into the background’, to not stand out as being different, fear of being labelled by others and fear of challenging others. Blending in gives phenomenological support to Gilligan’s (1990 accounts of silencing and loss of relation to self in adolescent girls, to a rendering of self as other. This phenomenological exploration is resonant also with de Beauvoir’s Second Sex and to a loss of capacity for introversion in Western culture, echoing Jung (1921. Blending in requires firmer addressing in social and emotional education (SEE, especially regarding challenge to self-management as emotional impulse and behaviour regulation. Self-management as blending in risks being a process of loss of voice and alienation of self.

  9. Numbers and meanings. Ideality in the incipient Husserl’s phenomenology

    José Manuel Chillón

    2017-04-01

    Full Text Available The reflection on numbers and meanings are a good example of how the incipient phenomenology is in the realm of pure logic. The paper states that, due to ambiguities in these early works and in order to draw a reflection that does not tear the philosophical personality of Husserl, the thesis of the ideality be read from the perspective of later works. This paper reconstructs, from initial analysis of the numbers and meanings, the thesis of the ideality Husserl which, in our view, detect the fundamental aspects of phenomenology despite the subsequent abandonment of the eidetic realism.

  10. Phenomenology of Mobile Phone Users’ Experiences About Mobilization in Social Relationships

    2017-09-01

    Full Text Available Technology has important role in communications and shapes people’s relations but also imposes its principles on these relationships. The term “Mobilization” refers to special form of life style characterized by properties such as speed and quantity. This investigation aimed at studying user experiences with regard to mobilization in human relationships. To this purpose, we conducted a phenomenological approach and arranged in-depth interviews with 12 users of mobile phones focusing on different virtual spaces. The use of mobile and virtual networks was researched with the view of "satisfaction and happiness."The obtained data were analyzed with Colaizzi’s 7 steps method and the results revealed 2 themes: “experience from technology” and “relational experiences” with more detailed sub-themes. Results showed that users pass through the stages of “experience from technology” i.e., from “familiarity”, to “attraction”, then “drown to nakedness, “to” pointlessness,” and ultimately “control”. Also participants’ communication experiences showed different types of confounded relationships. This process called mobilization, in which the characteristics, application context, and specific nature of the mobile phone use enter the human relationships and change them. Indeed, mobilization is not a technologic process but is a cultural one. The problem is not the invention but is the feel and urge to use this technology.

    Guerra, Karina Juliana; Spiri, Wilza Carla

    2013-01-01

    This study aimed at understanding the meaning of leadership to undergraduate nursing students and the expectation related to their professional practice. Phenomenology was used as theoretical framework. Fifteen undergraduate nursing students were recruited as subjects and answered the following question: "What do you understand by leadership, and how can it be applied in your professional practice?" The topics which were revealed and analyzed, Leadership Styles and Leadership Exercise, enabled us to understand that the meaning attributed to leadership is unveiled as a dynamic process, and the style adopted is the form to lead a team; therefore, an ideal leadership style does not exist. In teaching, the leadership style began to be discussed when the participant forms of personnel management were approached. In leadership practice, the dissociation between leadership theory and practice is emphasized, pointing out that integration with practice is relevant for leadership learning.

  12. MYSTICAL ASPECT OF EDITH STEIN'S ANTHROPOLOGY: FROM PHENOMENOLOGY TO THOMISM

    Directory of Open Access Journals (Sweden)

    J. A. Shabanova

    2016-12-01

    Full Text Available The aim of the study is to find mystical elements in Edith Stein's anthropology as a connecting principle between phenomenology and Thomism. Relying on methodological definition of philosophical mystic, as a matching of theological and philosophical doctrines, based upon reflection on experience of ecstatic unity with the Absolute, it was shown that phenomenology is implicitly directed towards research of real structure of immediate experience which in all its limits approaches to mystical experience. Not the mind and not the faith, but will (that directs knowledge to mystical unity of immanent subject and transcendental object in finding the truth is defining for the mystical character of Stein's creative method. Stein, being a bright representative of phenomenology, gradually disagrees with Husserl at some points: 1. Stein considers the world as an immediate contemplation on the entity that transcends the identity of being and thinking; 2. In her opinion, phenomenology neglects the ontological Absolute. As a result, there is misplace of the Absolute by structural-cognitive aims, that, in its turn, was a reason for amalgamation of onthology and epistemology, according to Stein's views. 3. Stein strives to overcome epistemological rationality and achieve a sphere of philosophical mystic where ontological object and epistemological subject are identical in the act of mystical contemplation. 4. Lack of metaphysical elements in phenomenology leads Stein to Thomism in which she potentially seeks a way out of metaphysical limits and the way which leads to the level of transpersonal states of mind. 5. Stein reproaches transcendentalism in loss of the world and she ignores the changes in Husserl's world outlook, his transcendental turn and genealogy of the trustworthy acquaintance with the world.

    2016-03-16

    Multiple studies have shown compromise of autobiographical memory and phenomenological reliving in Alzheimer's disease (AD). We investigated various phenomenological features of autobiographical memory to determine their relative vulnerability in AD. To this aim, participants with early AD and cognitively normal older adult controls were asked to retrieve an autobiographical event and rate on a five-point scale metacognitive judgments (i.e., reliving, back in time, remembering, and realness), component processes (i.e., visual imagery, auditory imagery, language, and emotion), narrative properties (i.e., rehearsal and importance), and spatiotemporal specificity (i.e., spatial details and temporal details). AD participants showed lower general autobiographical recall than controls, and poorer reliving, travel in time, remembering, realness, visual imagery, auditory imagery, language, rehearsal, and spatial detail-a decrease that was especially pronounced for visual imagery. Yet, AD participants showed high rating for emotion and importance. Early AD seems to compromise many phenomenological features, especially visual imagery, but also seems to preserve some other features.

  1. Phenomenology of Minimal Unified Tree Level Gauge Mediation at the LHC

    CERN Document Server

    Monaco, Maurizio; Romanino, Andrea; Spinrath, Martin

    2013-01-01

    We study the collider phenomenology of the minimal unified version of the supersymmetry breaking scheme called Tree-level Gauge Mediation. We identify a peculiar source of gaugino mass non-universality related to the necessary SU(5)-breaking in the light fermion mass ratios and a gaugino mass sum rule at the GUT scale, 3 M_2 + 2 M_3 = 5 M_1, which represents a smoking gun of this scenario, together with the known tree-level sfermion mass ratio \\tilde m_{d^c,l} = \\sqrt{2} \\tilde m_{q,u^c,e^c}. The boundary conditions of the soft SUSY breaking terms can be parameterised in terms of six relevant parameters only (plus the sign of the \\mu-parameter). We analyze the parameter space and define three benchmark points, corresponding to the three possible NLSPs, a bino- or wino-like neutralino or the stau. The LSP is the gravitino as in gauge mediation. For these benchmark points we show possible signatures at the LHC focusing on the Razor variable. We also comment on the Higgs mass.

  2. Pathophysiology of obsessive-compulsive disorder: a necessary link between phenomenology, neuropsychology, imagery and physiology.

    Aouizerate, Bruno; Guehl, Dominique; Cuny, Emmanuel; Rougier, Alain; Bioulac, Bernard; Tignol, Jean; Burbaud, Pierre

    2004-02-01

    Obsessive-compulsive disorder (OCD) is characterized by repetitive intrusive thoughts and compulsive time-consuming behaviors classified into three to five distinct symptom dimensions including: (1) aggressive/somatic obsessions with checking compulsions; (2) contamination concerns with washing compulsions; (3) symmetry obsessions with counting/ordering compulsions; (4) hoarding obsessions with collecting compulsions; and (5) sexual/religious concerns. Phenomenologically, OCD could be thought of as the irruption of internal signals centered on the erroneous perception that "something is wrong" in a specific situation. This generates severe anxiety, leading to recurrent behaviors aimed at reducing the emotional tension. In this paper, we examine how the abnormalities in brain activity reported in OCD can be interpreted in the light of physiology after consideration of various approaches (phenomenology, neuropsychology, neuroimmunology and neuroimagery) that contribute to proposing the central role of several cortical and subcortical regions, especially the orbitofrontal cortex (OFC), the anterior cingulate cortex (ACC), the dorsolateral prefrontal cortex (DLPC), the head of the caudate nucleus and the thalamus. The OFC is involved in the significance attributed to the consequences of action, thereby subserving decision-making, whereas the ACC is particularly activated in situations in which there are conflicting options and a high likelihood of making an error. The DLPC plays a critical part in the cognitive processing of relevant information. This cortical information is then integrated by the caudate nucleus, which controls behavioral programs. A dysfunction of these networks at one or several stages will result in the emergence and maintenance of repetitive thoughts and characteristic OCD behavior. Copyright 2004 Elsevier Ltd.

    2009-01-01

    A phenomenological quasiparticle model, featuring dynamically generated self-energies of excitation modes, successfully describes lattice QCD results relevant for the QCD equation of state and related quantities both at zero and non-zero net baryon density. Here, this model is extended to study bulk and shear viscosities of the gluon-plasma within an effective kinetic theory approach. In this way, the compatibility of the employed quasiparticle ansatz with the apparent low viscosities of the strongly coupled deconfined gluonic medium is shown.

    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.

  5. The usage of amount, quantity and body in a corpus of biology

    Directory of Open Access Journals (Sweden)

    Purificación Sánchez Hernández

    2002-04-01

    Full Text Available Grammars and dictionaries usually offer relevant and accurate information to students of a second language. However, the meaning of a textual element is often dynamic and that information is not always based on real usage patterns. New occurrences on the object level in new contexts can introduce novel semantic potentials, so that existing interpretations may be superseded by new ones. Concordancing has been shown to be one of the most important tools to facilitate the understanding of the usage patterns of a language. In this paper we examine the differences between amount, quantity and body as terms expressing magnitude, sum and size in a corpus of Biology. According to some popular dictionaries and grammars, the terms amount and quantity have always been considered synonymous terms for expressing magnitude, size and sum. We demonstrate that, according to our records, they cannot be always used as synonymous terms since they have different patterns of usage. On the other hand there are other forms, such as body, that appear in our Corpus, implying magnitude, size and sum, that are not usually described as having such meanings in dictionaries.

    In spite of the extraordinary success of the Standard Model (SM) supplemented with massive neutrinos in accounting for the whole huge bulk of phenomenology which has been accumulating in the last three decades, there exist strong theoretical reasons in particle physics and significant 'observational' hints in astroparticle physics for new physics beyond it. My lecture is devoted to a critical assessment of our belief in such new physics at the electroweak scale, in particular identifying it with low-energy supersymmetric extensions of the SM. I'll explain why we have concrete hopes that this decade will shed definite light on what stands behind the phenomenon of electroweak symmetry breaking

    To investigate behaviours related to four alcohol policy variables (policy-relevant behaviours) and demographic variables in relation to typical quantities of alcohol consumed on-premise in six International Alcohol Control study countries. General population surveys with drinkers using a comparable survey instrument and data analysed using path analysis in an overall model and for each country. typical quantities per occasion consumed on-premise; gender, age; years of education, prices paid, time of purchase, time to access alcohol and liking for alcohol advertisements. In the overall model younger people, males and those with fewer years of education consumed larger typical quantities. Overall lower prices paid, later time of purchase and liking for alcohol ads predicted consuming larger typical quantities; this was found in the high-income countries, less consistently in the high-middle-income countries and not in the low middle-income country. Three policy-relevant behaviours (prices paid, time of purchase, liking for alcohol ads) mediated the relationships between age, gender, education and consumption in high-income countries. International Alcohol Control survey data showed a relationship between policy-relevant behaviours and typical quantities consumed and support the likely effect of policy change (trading hours, price and restrictions on marketing) on heavier drinking. The path analysis also revealed policy-relevant behaviours were significant mediating variables between the effect of age, gender and educational status on consumption. However, this relationship is clearest in high-income countries. Further research is required to understand better how circumstances in low-middle-income countries impact effects of policies. © 2018 The Authors Drug and Alcohol Review published by John Wiley & Sons Australia, Ltd on behalf of Australasian Professional Society on Alcohol and other Drugs.

  8. Memory-Based Quantity Discrimination in Coyotes (Canis latrans

    Directory of Open Access Journals (Sweden)

    Salif Mahamane

    2014-08-01

    Full Text Available Previous research has shown that the ratio between competing quantities of food significantly mediates coyotes‘ (Canis latrans ability to choose the larger of two food options. These previous findings are consistent with predictions made by Weber‘s Law and indicate that coyotes possess quantity discrimination abilities that are similar to other species. Importantly, coyotes‘ discrimination abilities are similar to domestic dogs (Canis lupus familiaris, indicating that quantitative discrimination may remain stable throughout certain species‘ evolution. However, while previously shown in two domestic dogs, it is unknown whether coyotes possess the ability to discriminate visual quantities from memory. Here, we address this question by displaying different ratios of food quantities to 14 coyotes before placing the choices out of sight. The coyotes were then allowed to select one of either non-visible food quantities. Coyotes‘ discrimination of quantity from memory does not follow Weber‘s Law in this particular task. These results suggest that working memory in coyotes may not be adapted to maintain information regarding quantity as well as in domestic dogs. The likelihood of a coyote‘s choosing the large option increased when it was presented with difficult ratios of food options first, before it was later presented with trials using more easily discriminable ratios, and when the large option was placed on one particular side. This suggests that learning or motivation increased across trials when coyotes experienced difficult ratios first, and that location of food may have been more salient in working memory than quantity of food.

    In this paper, we examine the consistency of the Large Hadron Collider (LHC) data collected during Runs 1 and 2 by the ATLAS and CMS experiments with the predictions of a 2-Higgs doublet model embedding vectorlike quarks (VLQs) for p p →H , A production and H , A →γ γ decay mechanisms, respectively, of (nearly) degenerate C P -even (H ) and C P -odd (A ) Higgs bosons. We show that a scenario containing one single VLQ with electromagnetic charge 2 /3 can explain the above ATLAS and CMS data for masses in the region 350 GeV ≤mVLQ≤1.5 TeV or so, depending on tan β , and for several values of the mixing angle between the top quark (t ) and its VLQ counterpart (T ). We then perform a global fit onto the model by including all relevant experimental as well as theoretical constraints. The surviving samples of our analysis are discussed within 2 σ of the LHC measurements. Additionally, we also comment on the recent anomalous result reported by CMS using Run 2 data on the associated Standard Model Higgs boson production with top quark pairs p p →t t ¯ h with an observed significance of 3.3 σ . Other than these specific examples, we also present a phenomenological analysis of the main features of the model, including the most promising T decay channels.

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

    Science.gov (United States)

    Nelson, Barnaby; Sass, Louis A

    2008-01-01

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

    Staudigl, Michael

    2013-01-01

    This article elaborates a relational phenomenology of violence. Firstly, it explores the constitution of all sense in its intrinsic relation with our embodiment and intercorporality. Secondly, it shows how this relational conception of sense and constitution paves the path for an integrative understanding of the bodily and symbolic constituents of violence. Thirdly, the author addresses the overall consequences of these reflections, thereby identifying the main characteristics of a relational...

  15. Quantities used in radiological protection

    International Nuclear Information System (INIS)

    Menossi, Carlos

    2010-01-01

    The application of ICRP recommendations requires knowledge of a variety of concepts and magnitudes. Many of them are employed in other fields of science and precision in its definition reflects this wide application. In this regard, information on quantities and basic units of radiation, which exists in numerous publications, are subjects of great interest. The characteristics and radiation effects are studied by physicists, biologists and chemists mainly. However, there are basics that must be known and to be recognized by general practitioners and specialists from all branches of medicine. The information on quantities and units are used only in radiation protection, have been obtained from the reports listed on the attached bibliography. Such quantities and units contain weighting factors used to provide for different types of radiation and energies that affect the body and thus take into account the relative radio-sensitivity of different tissues. Additionally, they have added a series of data for a better understanding of the units: for example, multiples and sub-multiples, and some examples of converting the units used in radiation protection.

  16. Husserlian Phenomenology as a Kind of Introspection

    Directory of Open Access Journals (Sweden)

    Christopher Gutland

    2018-06-01

    Full Text Available The thesis of this article is that Husserl's proposed method for intuitively exploring the essential or a priori laws of consciousness is a kind of introspection. After a first reflection on the meaning of “introspection,” four elements of Husserl's methodology are introduced: the principle of all principles, epoché, phenomenological reduction, and eidetic variation. These features are then individually related to six common features Eric Schwitzgebel mentions in his definition of introspection in the Stanford Encyclopedia of Philosophy. The explanation of these elements is complemented by mentioning phenomenological insights they offer. It is thereby shown how Husserl's methodology evades some of the pitfalls of introspection and reaches a secure ground. Such pitfalls are: a relatively uncontrolled and varying scope of awareness, false prejudices, and problems distinguishing between idiosyncratic and general features of consciousness. As this article is written for the section Theoretical and Philosophical Psychology, Husserl's approach is developed in relation to two well-known philosophical systems that considerably influenced him, Hume's and Kant's.

  17. Destruction as a Step in Heidegger's Phenomenology

    Directory of Open Access Journals (Sweden)

    M.J Safian

    2014-08-01

    Full Text Available One of the most controversial issues in Heidegger’s philosophy is his claim that western philosophy tradition has overlooked the issue of Being. Heidegger’s attempt is to reveal the origins of this negligence by means of destruction. However, it seems that through such claim Heidegger aims to destroy and disvalue this tradition. In addition to defining and explaining destruction, our purpose in this article is to show that Heidegger’s goal is not to destroy the tradition of philosophy but the term destruction refers to a process which is a step in Heidegger’s phenomenology by means of which one can conceive and perceive Being better because only through such destruction ontology can fully assure itself in a phenomenological way of the genuine character of its concepts. The necessity of doing destruction in Heidegger’s thought has also been discussed and his persistence on it has been shown in two of his works, one belongs to early and another to later Heidegger.

    Science.gov (United States)

    Palmer, Matthew A; Brewer, Neil; McKinnon, Anna C; Weber, Nathan

    2010-02-01

    This study investigated whether measuring the phenomenology of eyewitness identification decisions aids evaluation of their accuracy. Witnesses (N=502) viewed a simulated crime and attempted to identify two targets from lineups. A divided attention manipulation during encoding reduced the rate of remember (R) correct identifications, but not the rates of R foil identifications or know (K) judgments in the absence of recollection (i.e., K/[1-R]). Both RK judgments and recollection ratings (a novel measure of graded recollection) distinguished correct from incorrect positive identifications. However, only recollection ratings improved accuracy evaluation after identification confidence was taken into account. These results provide evidence that RK judgments for identification decisions function in a similar way as for recognition decisions; are consistent with the notion of graded recollection; and indicate that measures of phenomenology can enhance the evaluation of identification accuracy.

  1. The covariance matrix of derived quantities and their combination

    International Nuclear Information System (INIS)

    Zhao, Z.; Perey, F.G.

    1992-06-01

    The covariance matrix of quantities derived from measured data via nonlinear relations are only approximate since they are functions of the measured data taken as estimates for the true values of the measured quantities. The evaluation of such derived quantities entails new estimates for the true values of the measured quantities and consequently implies a modification of the covariance matrix of the derived quantities that was used in the evaluation process. Failure to recognize such an implication can lead to inconsistencies between the results of different evaluation strategies. In this report we show that an iterative procedure can eliminate such inconsistencies

  2. Bridging Mechanistic and Phenomenological Models of Complex Biological Systems.

    Science.gov (United States)

    Transtrum, Mark K; Qiu, Peng

    2016-05-01

    The inherent complexity of biological systems gives rise to complicated mechanistic models with a large number of parameters. On the other hand, the collective behavior of these systems can often be characterized by a relatively small number of phenomenological parameters. We use the Manifold Boundary Approximation Method (MBAM) as a tool for deriving simple phenomenological models from complicated mechanistic models. The resulting models are not black boxes, but remain expressed in terms of the microscopic parameters. In this way, we explicitly connect the macroscopic and microscopic descriptions, characterize the equivalence class of distinct systems exhibiting the same range of collective behavior, and identify the combinations of components that function as tunable control knobs for the behavior. We demonstrate the procedure for adaptation behavior exhibited by the EGFR pathway. From a 48 parameter mechanistic model, the system can be effectively described by a single adaptation parameter τ characterizing the ratio of time scales for the initial response and recovery time of the system which can in turn be expressed as a combination of microscopic reaction rates, Michaelis-Menten constants, and biochemical concentrations. The situation is not unlike modeling in physics in which microscopically complex processes can often be renormalized into simple phenomenological models with only a few effective parameters. The proposed method additionally provides a mechanistic explanation for non-universal features of the behavior.

  6. Glueball phenomenology within a nonlocal approach

    International Nuclear Information System (INIS)

    Giacosa, F.

    2005-01-01

    In this thesis we describe the properties of glueball phenomenology within a nonlocal covariant constituent approach. The search for glueballs, their theoretical description and the mixing with quarkonia mesons is an active and unsolved issue of hadronic QCD. Different models and assignments have been proposed, but up to now no certain statement about their existence can be done. After introducing the theoretical framework in which we will work in, the attention will be focused on the problem of the scalar glueball, which lattice QCD predicts to be the lightest gluonic state with a mass between 1.4-1.8 GeV. In the same mass region one encounters many scalar resonances; mixing between the bare glueball and quarkonia states is therefore likely. In a covariant constituent approach one cannot define rigorously a mixing matrix connecting the bare to physical fields. However, we propose a definition which satisfies the correct requirements and which can be compared to other phenomenological studies. The two-photon decay of isoscalar-scalar states is believed to be crucial to pin down the flavor content of the resonances between 1 and 2 GeV. We discuss and calculate the two-photon decay rates of the mixed states glueball-quarkonia, getting results which are consistent with the current experimental upper limits

  7. Phenomenological modeling of long range noncontact friction in micro- and nanoresonators

    International Nuclear Information System (INIS)

    Gusso, Andre

    2011-01-01

    Motivated by the results of an experiment using atomic force microscopy performed by Gotsmann and Fuchs [Phys. Rev. Lett. 86, 2597 (2001)], where a strong energy loss due to the tip-sample interaction was measured, we investigate the potential implications of this energy loss channel to the quality factor of suspended micro- and nanoresonators. Because the observed tip-sample dissipation remains without a satisfactory theoretical explanation, two phenomenological models are proposed to generalize the experimental observations. In the minimal phenomenological model the range of validity of the power law found experimentally for the damping coefficient is assumed to be valid for larger separations. A more elaborate phenomenological model assumes that the noncontact friction is a consequence of the Casimir force acting between the closely spaced surfaces. Both models provide quantitative results for the noncontact friction between any two objects which are then used to estimate the energy loss for suspended bar micro- and nanoresonators. It is concluded that the energy loss due to the unknown mechanism has the potential to seriously restrict the quality factor of both micro- and nanoresonators.

  8. Phenomenological aspects of heterotic orbifold models at one loop

    International Nuclear Information System (INIS)

    Birkedal-Hansen, A.; Binetruy, P.; Mambrini, Y.; Nelson, B.

    2003-01-01

    We provide a detailed study of the phenomenology of orbifold compactifications of the heterotic string within the context of supergravity effective theories. Our investigation focuses on those models where the soft Lagrangian is dominated by loop contributions to the various soft supersymmetry breaking parameters. Such models typically predict non-universal soft masses and are thus significantly different from minimal supergravity and other universal models. We consider the pattern of masses that are governed by these soft terms and investigate the implications of certain indirect constraints on supersymmetric models, such as flavor-changing neutral currents, the anomalous magnetic moment of the muon and the density of thermal relic neutralinos. These string-motivated models show novel behavior that interpolates between the phenomenology of unified supergravity models and models dominated by the superconformal anomaly

    2012-01-01

    We study the impact of semi-annihilations χχ ↔ χX; where χ is dark matter and X is any standard model particle, on dark matter phenomenology. We formulate scalar dark matter models with minimal field content that predict non-trivial dark matter phenomenology for different discrete Abelian symmetries Z N , N > 2, and contain semi-annihilation processes. We implement such an example model in micrOMEGAs and show that semi-annihilations modify the phenomenology of this type of models. (authors)

  10. Using Phenomenology to Study how Junior and Senior High School Students in Japan Perceive their Volunteer Efforts

    Directory of Open Access Journals (Sweden)

    Kayoko Ueda

    2009-06-01

    Full Text Available The purpose of this paper is to describe the methods used in a phenomenological study aimed at understanding students' perceptions of volunteer experiences from the viewpoint of their existential meanings. In Japan, as volunteer activities have just been recently introduced to youth education, it is necessary to verify the effect of the activity on the students. The authors present phenomenological reduction, which is a fundamental concept in phenomenology, as a health care research method to elucidate the essence of people's lived experiences. The 22 statements presented from volunteer students' group discussion after their practices were redescribed by phenomenological reduction, a method of valid interpretation based on their embodiment and desire. The phenomenological approach allows us to understand the essence of students' perceptions in terms of their purpose in life, which suggests that educators could inspire the students to realize existential growth by participating in volunteer activities through practical communications with others.

  13. Hypergraph topological quantities for tagged social networks

    Science.gov (United States)

    Zlatić, Vinko; Ghoshal, Gourab; Caldarelli, Guido

    2009-09-01

    Recent years have witnessed the emergence of a new class of social networks, which require us to move beyond previously employed representations of complex graph structures. A notable example is that of the folksonomy, an online process where users collaboratively employ tags to resources to impart structure to an otherwise undifferentiated database. In a recent paper, we proposed a mathematical model that represents these structures as tripartite hypergraphs and defined basic topological quantities of interest. In this paper, we extend our model by defining additional quantities such as edge distributions, vertex similarity and correlations as well as clustering. We then empirically measure these quantities on two real life folksonomies, the popular online photo sharing site Flickr and the bookmarking site CiteULike. We find that these systems share similar qualitative features with the majority of complex networks that have been previously studied. We propose that the quantities and methodology described here can be used as a standard tool in measuring the structure of tagged networks.

  15. Internally consistent gamma ray burst time history phenomenology

    International Nuclear Information System (INIS)

    Cline, T.L.

    1985-01-01

    A phenomenology for gamma ray burst time histories is outlined. Order of their generally chaotic appearance is attempted, based on the speculation that any one burst event can be represented above 150 keV as a superposition of similarly shaped increases of varying intensity. The increases can generally overlap, however, confusing the picture, but a given event must at least exhibit its own limiting characteristic rise and decay times if the measurements are made with instruments having adequate temporal resolution. Most catalogued observations may be of doubtful or marginal utility to test this hypothesis, but some time histories from Helios-2, Pioneer Venus Orbiter and other instruments having one-to several-millisecond capabilities appear to provide consistency. Also, recent studies of temporally resolved Solar Maximum Mission burst energy spectra are entirely compatible with this picture. The phenomenology suggested here, if correct, may assist as an analytic tool for modelling of burst processes and possibly in the definition of burst source populations

  20. Mathematical and information-geometrical entropy for phenomenological Fourier and non-Fourier heat conduction

    Science.gov (United States)

    Li, Shu-Nan; Cao, Bing-Yang

    2017-09-01

    The second law of thermodynamics governs the direction of heat transport, which provides the foundational definition of thermodynamic Clausius entropy. The definitions of entropy are further generalized for the phenomenological heat transport models in the frameworks of classical irreversible thermodynamics and extended irreversible thermodynamics (EIT). In this work, entropic functions from mathematics are combined with phenomenological heat conduction models and connected to several information-geometrical conceptions. The long-time behaviors of these mathematical entropies exhibit a wide diversity and physical pictures in phenomenological heat conductions, including the tendency to thermal equilibrium, and exponential decay of nonequilibrium and asymptotics, which build a bridge between the macroscopic and microscopic modelings. In contrast with the EIT entropies, the mathematical entropies expressed in terms of the internal energy function can avoid singularity paired with nonpositive local absolute temperature caused by non-Fourier heat conduction models.

  3. Time-dependent fatigue--phenomenology and life prediction

    International Nuclear Information System (INIS)

    Coffin, L.F.

    1979-01-01

    The time-dependent fatigue behavior of materials used or considered for use in present and advanced systems for power generation is outlined. A picture is first presented to show how basic mechanisms and phenomenological information relate to the performance of the component under consideration through the so-called local strain approach. By this means life prediction criteria and design rules can be formulated utilizing laboratory test information which is directly translated to predicting the performance of a component. The body of phenomenological information relative to time-dependent fatigue is reviewed. Included are effects of strain range, strain rate and frequency, environment and wave shape, all of which are shown to be important in developing both an understanding and design base for time dependent fatigue. Using this information, some of the current methods being considered for the life prediction of components are reviewed. These include the current ASME code case, frequency-modified fatigue equations, strain range partitioning, the damage function method, frequency separation and damage rate equations. From this review, it is hoped that a better perspective on future directions for basic material science at high temperature can be achieved

  4. Phenomenology and the Possibility of Religious Experience

    Mercer Ronald L.

    2017-10-01

    Full Text Available Work in what has been known as the theological turn in French phenomenology describes the way in which human beings are always, already open to a religious encounter. This paper will focus on Levinas as a proper transcendental phenomenologist as would be characterized by parts of Husserl and Husserl’s last assistant Eugen Fink. What Levinas does in his phenomenology of the face/other (which gets tied up in religious language is to describe an absolute origin out of which the subject arises. This point of origin structures the self in such a way as to always, already be open to that which overflows experience and, thus, makes possible the very experience of an encounter with the numinous. Such an approach to religious experience for which I am arguing simply takes Levinas at his word when he declares “The idea of God is an idea that cannot clarify a human situation. It is the inverse that is true.” (“Transcendence and Height” Understanding the structure of the subject as open to that which cannot be reduced/totalized/ encapsulated is to recognize that the human situation is ready for the possibility of religious experience.

  6. Phenomenology of neutral current interactions

    International Nuclear Information System (INIS)

    Sakurai, J.J.

    1978-01-01

    Neutral-current interactions are discussed within a rather general phenomenological framework without commitment to any particular theoretical model. Three points are kept in mind: what various experiments really measure; the performing of complete experiments to determine the neutral-current couplings; and the testing of models in an objective, emotionally uninvolved manner. The following topics are considered: neutrino-electron scattering, hadronic currents and models, neutrino-induced inclusive hadronic reactions, neutrino-induced exclusive hadronic reactions, and neutral-current phenomena without neutrinos. In conclusion, what has actually been learned about neutral-current interactions is summarized. 9 figures, 2 tables

We will show how a TeV scale tension may be compatible with the existence of Large Extra Dimensions and how anomalous U(1)'s can give rise to interesting signatures at LHC or in cosmic rays. Finally, we discuss unoriented D-brane instantons as a source of non-perturbative effects that can contribute to moduli stabilization and susy braking in combination with fluxes. We conclude with an outlook and directions for future work.

  8. DOE approach to threshold quantities

    International Nuclear Information System (INIS)

    Wickham, L.E.; Kluk, A.F.; Department of Energy, Washington, DC)

    1985-01-01

    The Department of Energy (DOE) is developing the concept of threshold quantities for use in determining which waste materials must be handled as radioactive waste and which may be disposed of as nonradioactive waste at its sites. Waste above this concentration level would be managed as radioactive or mixed waste (if hazardous chemicals are present); waste below this level would be handled as sanitary waste. Ideally, the threshold must be set high enough to significantly reduce the amount of waste requiring special handling. It must also be low enough so that waste at the threshold quantity poses a very small health risk and multiple exposures to such waste would still constitute a small health risk. It should also be practical to segregate waste above or below the threshold quantity using available instrumentation. Guidance is being prepared to aid DOE sites in establishing threshold quantity values based on pathways analysis using site-specific parameters (waste stream characteristics, maximum exposed individual, population considerations, and site specific parameters such as rainfall, etc.). A guidance dose of between 0.001 to 1.0 mSv/y (0.1 to 100 mrem/y) was recommended with 0.3 mSv/y (30 mrem/y) selected as the guidance dose upon which to base calculations. Several tasks were identified, beginning with the selection of a suitable pathway model for relating dose to the concentration of radioactivity in the waste. Threshold concentrations corresponding to the guidance dose were determined for waste disposal sites at a selected humid and arid site. Finally, cost-benefit considerations at the example sites were addressed. The results of the various tasks are summarized and the relationship of this effort with related developments at other agencies discussed

Here the volume-, as well as the mass-flow rate, as derived quantities are of particular interest. The application of these quantities in relation to the legal units of measurement is specifically described. In addition the quantity equation and further the quantity equation adapted to the use of suitable units and their modes of application are compared. In the appendix four examples clarify these modes. Special attention is paid to the quantity equation adapted to practically oriented units. The applications of this type of equation in VDI regulations, standards and other technical guidelines for measurement of flow are mentioned. Moreover, the meaning of the standard state for the comparison of flows of gaseous fluids is illustrated. The difficulties concerning an international agreement on uniform standard temperature are explained. Starting from there, the advantages of the fundamental quantity 'amount of substance' applied to the measurement of flow are described. The use of this quantity for the thermodynamic state of ideal and real gases, respectively gas mixtures, is demonstrated in the appendix by an example. (orig.) [de

  10. Physics on the smallest scales: an introduction to minimal length phenomenology

    Many modern theories which try to unify gravity with the Standard Model of particle physics, such as e.g. string theory, propose two key modifications to the commonly known physical theories: the existence of additional space dimensions; the existence of a minimal length distance or maximal resolution. While extra dimensions have received a wide coverage in publications over the last ten years (especially due to the prediction of micro black hole production at the Large Hadron Collider), the phenomenology of models with a minimal length is still less investigated. In a summer study project for bachelor students in 2010, we have explored some phenomenological implications of the potential existence of a minimal length. In this paper, we review the idea and formalism of a quantum gravity-induced minimal length in the generalized uncertainty principle framework as well as in the coherent state approach to non-commutative geometry. These approaches are effective models which can make model-independent predictions for experiments and are ideally suited for phenomenological studies. Pedagogical examples are provided to grasp the effects of a quantum gravity-induced minimal length. This paper is intended for graduate students and non-specialists interested in quantum gravity.

  11. Phenomenological Psychopathology: From Spatial Disorder to the Problem of Disembodied Desire

    2014-12-01

    Full Text Available This study presents a phenomenological analysis of a case of schizotypal personality disorder used as a concrete starting point to formulate a basic phenomenological theory of embodied and disembodied desire. After describing the core symptoms of the patient (i.e. mainly his spatial disorder from a first-person per-spective, the problem of disembodied desire is introduced in relation to patient’s imaginary that is lived as an isolated experience condemned to remaining unrealized. The case analysis refers to Blankenburg’s concept of the loss of natural self-experience and to its contemporary development, i.e., the psychopathology of common sense, conceiving schizophrenia, and schizotypal personality disorder, as a syndrome rooted in ipseity disturbance and in disembodiment of the self. Disembodied desire is then qualified as a disorder due not to neurotic defense mechanisms, but rather to more pervasive self-disorders. In the final part, the problem of disembodied desire is addressed starting from a basic phenomenological theory of desire, dealing both with drive intentionality, as the transcendental condition of the ego-constitution, and with imagination, as the distanced self-representation of drive and as a structural possibility of distancing the immediacy of bodily experience.

    This paper aimed to report the experience of driving modes of an interview on data production in phenomenological research. The proposed study is an experience report of a phenomenological investigation in which the researchers present their experience with children, considering the interview as an existential encounter. It describes ways of conducting the interview in its ontic and ontological dimensions. The ontic dimension refers to the facts related to the interview, presented in the researcher, in the researched subject and in the environment; both in its planning and its development. The ontological dimension is based on empathy and intersubjectivity. The interview enables the access to meaningful structures to comprehend the being, as a way of building investigative/assistance possibilities that enable to reveal the being of the human.

  13. Making humor together: phenomenology and interracial humor

    Directory of Open Access Journals (Sweden)

    Michael D. Barber

    2016-01-01

    Full Text Available This paper explains humor through phenomenological concepts and methods. The three major theories of humor: Superiority, Relief, and Incongruity depend on the thwarting of intentional expectations. Since one experiences an incongruity between what is intended and what is actually experienced, the incongruity theory affords the best explanation, but intentionality remains fundamental for all theories. Theorists of humor rightly insist that the enjoyment of humorous incongruity completes the definition of humor, but such enjoyment also depends on a special epoché, usually elicited by the cues of an interlocutor who invites the listener to leap together into the humorous finite province of meaning. In this province, actions and statements, hurtful in everyday life, such as a pie thrown at someone who ducks as the pie hits another, produce laughter. This comic epoché resembles the phenomenological epoché in its distancing from everyday life, and, like the phenomenological epoché, it opens everyday experience to reflection. Although one often experiences and enjoys humor alone, humor is thoroughly intersubjective and more frequently occurs when two persons participate in the humorous epoché together. The opportunities for making humor together are enhanced to the extent the partners differ in their expectations and responses to situations. Those differences, including bodily differences, often result from the complex intersubjective networks, including culture. As in the case of a seemingly solitary activity like reflection, which one learns from others and exercises on one’s own autonomously, one internalizes others’ styles of humor and discovers such internalization through reflection on one’s «because motives». On the basis of these features – intentionality, epoché, and intersubjectivity, the paper concludes by briefly examining an example of interracial humor. Despite the racist character of much interracial humor, the example

  19. New quantities in radiation protection and conversion coefficients

    International Nuclear Information System (INIS)

    1986-01-01

    Four new quantities have been proposed by the ICRP for use in radiation protection from external sources, i.e. the ambient dose equivalent, the directional dose equivalent, the individual dose equivalent (penetrating), and the individual dose equivalent (superficial). These quantities are briefly described together with two new concepts of expanded and aligned fields. The BCRU recommends that these quantities should be adopted for use in the UK together with conversion coefficients when re-calibrating existing instruments, reporting the results of measurements and designing instruments.

  20. Trait Dissociation and the Subjective Affective, Motivational, and Phenomenological Experience of Self-Defining Memories

    Science.gov (United States)

    Sutin, Angelina R.; Stockdale, Gary D.

    2010-01-01

    The present research reports two studies that examine the relation between non-pathological trait dissociation and the subjective affect, motivation, and phenomenology of self-defining memories. In Study 1 (N=293), participants retrieved and rated the emotional and motivational experience of a general and a positive and negative achievement-related memory. Study 2 (N=449) extended these ratings to relationship-related memories and the phenomenological experience of the memory. Dissociation was associated with incongruent affect in valenced memories (e.g., positive affect in a negative memory) and memories that were visually incoherent and saturated with power motivation, hubristic pride, and shame, regardless of valence or domain. The present findings demonstrate that autobiographical memories, which integrate emotional, motivational, and phenomenological components, reflect the emotional and motivational processes inherent to dissociation.

  1. Phenomenology of a nonstandard Higgs boson in WLWL scattering

    International Nuclear Information System (INIS)

    Koulovassilopoulos, V.; Chivukula, R.S.

    1994-01-01

    In this paper we consider the phenomenology of a nonstandard Higgs boson in longitudinal gauge boson scattering. First, we present a composite Higgs model [based on an SU(4)/Sp(4) chiral-symmetry breaking pattern] in which there is a nonstandard Higgs boson. Then we explore, in a model-independent way, the phenomenology of such a nonstandard Higgs boson by calculating the leading one-loop logarithmic corrections to longitudinal gauge boson scattering. This calculation is done using the equivalence theorem and the Higgs boson is treated as a scalar-isoscalar resonance coupled to the Goldstone bosons of the SU(2) L xSu(2) R /SU(2) V chiral symmetry breaking. We show that the most important deviation from the one-Higgs-doublet standard model is parametrized by one unknown coefficient which is related to the Higgs-boson width. The implications for future hadron colliders are discussed

  2. The ICRU dose equivalence quantities in radiation protection

    International Nuclear Information System (INIS)

    Grimbergen, T.W.M.

    1990-09-01

    The definitions and application of the new ICRU radiation protection quantities have been reviewed and studied in literature. Special emphasis was laid on the consequences of the use of the new quantities by personnel dosimetry services, and on the consequences of the use of the new quantities during an intercomparison programme for dosimetry services. The study shows that the recommendations of the ICRU are not yet complete and not fully realizable. This means that the dosimetry services always have to make certain approximations, when they use the new quantities. In literature, several approaches have been proposed. The feasibility of an approach depends on the characteristics of the dosimeters used. The use of different approaches by the dosimetry services is thought to be of possible influence on the results of an intercomparison programme. (author). 42 refs.; 3 figs.; 1 tab

  8. Light-cone quantization and QCD phenomenology

    International Nuclear Information System (INIS)

    Brodsky, S.J.; Robertson, D.G.

    1995-01-01

    In principle, quantum chromodynamics provides a fundamental description of hadronic and nuclear structure and dynamics in terms of their elementary quark and gluon degrees of freedom. In practice, the direct application of QCD to reactions involving the structure of hadrons is extremely complex because of the interplay of nonperturbative effects such as color confinement and multi-quark coherence. A crucial tool in analyzing such phenomena is the use of relativistic light-cone quantum mechanics and Fock state methods to provide tractable and consistent treatments of relativistic many-body systems. In this article we present an overview of this formalism applied to QCD, focusing in particular on applications to the final states in deep inelastic lepton scattering that will be relevant for the proposed European Laboratory for Electrons (ELFE), HERMES, HERA, SLAC, and CEBAF. We begin with a brief introduction to light-cone field theory, stressing how it many allow the derivation of a constituent picture, analogous to the constituent quark model, from QCD. We then discuss several applications of the light-cone Fock state formalism to QCD phenomenology. The Fock state representation includes all quantum fluctuations of the hadron wavefunction, including far off-shell configurations such as intrinsic charm and, in the case of nuclei, hidden color. In some applications, such as exclusive processes at large momentum transfer, one can make first-principle predictions using factorization theorems which separate the hard perturbative dynamics from the nonpertubative physics associated with hadron binding. The Fock state components of the hadron with small transverse size, which dominate hard exclusive reactions, have small color dipole moments and thus diminished hadronic interactions. Thus QCD predicts minimal absorptive corrections, i.e., color transparency for quasi-elastic exclusive reactions in nuclear targets at large momentum transfer

    These notes are an abbreviated version of lectures given at the 1997 Zakopane School. They contain two topics. The first is a description in elementary terms of the basic ideas underlying the speculative hypothesis that pieces of strong-interaction vacuum with a rotated chiral order parameter, disoriented chiral condensate or DCC, might be produced in high energy elementary particle collisions. The second topic is a discussion of the phenomenological techniques which may be applied to data in order to experimentally search for the existence of DCC

    Grant, Jon E; Schreiber, Liana R N; Odlaug, Brian L

    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.

    Dendy, R.O.

    2002-01-01

    There is substantial experimental evidence that simple diffusive models for turbulent transport are insufficient to produce all the confinement phenomena observed in tokamaks. This paper reports on the emerging linkage between rapid, nonlocal, nondiffusive transport and overall confinement phenomenology including edge pedestals, enhanced confinement, ELMs, and internal transport barriers. Modern statistical physics techniques are used to construct simple models that generate many of the distinctive elements of global tokamak confinement phenomenology. The similarities are deep and are quantified. These results imply that current observations of avalanching transport in tokamaks may be deeply linked to the fundamental global features of tokamak plasma confinement. (author)

    Full Text Available Quantity discrimination has been studied extensively in different non-human animal species. In the current study, we tested eleven hand-raised wolves (Canis lupus in a two-way choice task. We placed a number of food items (one to four sequentially into two opaque cans and asked the wolves to choose the larger amount. Moreover, we conducted two additional control conditions to rule out non-numerical properties of the presentation that the animals might have used to make the correct choice. Our results showed that wolves are able to make quantitative judgments at the group, but also at the individual level even when alternative strategies such as paying attention to the surface area or time and total amount are ruled out. In contrast to previous canine studies on dogs (Canis familiaris and coyotes (Canis latrans, our wolves’ performance did not improve with decreasing ratio, referred to as Weber’s law. However, further studies using larger quantities than we used in the current setup are still needed to determine whether and when wolves’ quantity discrimination conforms to Weber’s law.

  14. Phenomenological applications of perturbative quantum chromodynamics

    International Nuclear Information System (INIS)

    Zahir, M.S.Z.

    1981-01-01

    In this thesis, three diffrent topics in high energy particle physics are investigated each of which is a case of theoretical and phenomenological application of perturbative Quantum Chromodynamics. The first topic is addressed to the structure of nucleons as probed in deep-inelastic lepton-nucleon scattering. Since, at present, meaningful calculations in Quantum Chromodynamics (QCD) can be done only for short distances or large momentum transfers, phenomenological applications of QCD to the full hadronic processes many a time require additional model dependent procedures. In this thesis, the structure functions of the nucleon in the framework of the valon model in which a nucleon is assumed to be a bound state of three valence quark clusters (valons) are analyzed. In the second topic the production of massive dimuons at large transverse momentum in Drell-Yan process is analyzed where it is believed that the dimuons acquire large transverse momentum through the emission or absorption of hard gluons. Following a model independent formalism, in this thesis, the lowest order QCD contributions to the structure functions in lepton-pair production are calculated and it is shown that there exist sum rules connecting the four sructure functions to be satisfied at zero rapidity and large transverse momentum of the muon-pair for similar interacting hadrons. In the third topic a discussion is given on how high energy photons can replace hadrons in new lepton-pair production process

    2014-04-01

    Full Text Available Grice (1975 pointed out that the ignorance inferences normally drawn when disjunctive sentences are uttered are cancelled when it is presupposed that speakers are not going to provide all of the relevant information that they have available (e.g., in the context of a treasure hunt. This argues that ignorance inferences depend on the maxim of quantity for their derivation. Here it is argued that the situation with Scalar Implicatures is different. This is expected by the grammatical theory of Scalar Implicatures, but not by standard Gricean or neo-Gricean alternatives. http://dx.doi.org/10.3765/sp.7.5 BibTeX info

    International Nuclear Information System (INIS)

    Camassa, R.; Levermore, C.D.

    1997-01-01

    We derive local conservation laws for layer-mean quantities in two general settings. When applied to Euler flows, the first of these settings yields well-known local conservation laws for quantities averaged between material surfaces. The second, however, leads to new local conservation laws for quantities involving the vorticity that are averaged between arbitrary surfaces. These produce the crucial vorticity conservation laws in shallow water models that admit nonhydrostatic and noncolumnar motion. Moreover, they seem to lie outside the Hamiltonian paradigm of fluid dynamics. The formalism generalizes to skew-symmetric matrix fields; applications to electromagnetism are suggested. copyright 1997 The American Physical Society

    2003-01-01

    Syringomyelia, considered a rare neurological disease, is relatively uninvestigated in the nursing literature. The aims of this qualitative phenomenological case study were to discover the nature, meanings, and dynamics of lived experiences of a 52-year-old Caucasian male with syringomyelia. Using van Manen's Method of Phenomenological inquiry (van Manen, 1990), data were collected, checked, and analyzed according to the philosophy, approach, and methodological procedures of phenomenology. Findings revealed an overarching theme of engulfment by disease. Essential themes included loss of abilities, struggles to adapt to changes, and life as a person who was disabled. Eleven sub-themes were also identified. Implications for nursing practice are discussed.

  1. Descriptive psychopathology, phenomenology, and the legacy of Karl Jaspers.

    Science.gov (United States)

    Häfner, Heinz

    2015-03-01

    With his early publications (1910-1913), Karl Jaspers created a comprehensive methodological arsenal for psychiatry, thus laying the foundation for descriptive psychopathology. Following Edmund Husserl, the founder of philosophical phenomenology, Jaspers introduced phenomenology into psychopathology as "static understanding," ie, the unprejudiced intuitive reproduction (Vergegenwärtigung) and description of conscious phenomena. In a longitudinal perspective, "genetic understanding" based on empathy reveals how mental phenomena arise from mental phenomena. Severance in understanding of, or alienation from, meaningful connections is seen as indicating illness or transition of a natural development into a somatic process. Jaspers opted for philosophy early. After three terms of law, he switched to studying medicine, came to psychopathology after very little training in psychiatry; to psychology without ever studying psychology; and to a chair in philosophy without ever studying philosophy. In the fourth and subsequent editions of his General Psychopathology, imbued by his existential philosophy, Jaspers partly abandoned the descriptive method.

TMD factorization naturally suggests alternative definitions of su...

  4. The relevance of Heidegger's philosophy of technology for biomedical ethics.

    Science.gov (United States)

    Svenaeus, Fredrik

    2013-02-01

    Heidegger's thoughts on modern technology have received much attention in many disciplines and fields, but, with a few exceptions, the influence has been sparse in biomedical ethics. The reason for this might be that Heidegger's position has been misinterpreted as being generally hostile towards modern science and technology, and the fact that Heidegger himself never subjected medical technologies to scrutiny but was concerned rather with industrial technology and information technology. In this paper, Heidegger's philosophy of modern technology is introduced and then brought to bear on medical technology. Its main relevance for biomedical ethics is found to be that the field needs to focus upon epistemological and ontological questions in the philosophy of medicine related to the structure and goal of medical practice. Heidegger's philosophy can help us to see how the scientific attitude in medicine must always be balanced by and integrated into a phenomenological way of understanding the life-world concerns of patients. The difference between the scientific and the phenomenological method in medicine is articulated by Heidegger as two different ways of studying the human body: as biological organism and as lived body. Medicine needs to acknowledge the priority of the lived body in addressing health as a way of being-in-the-world and not as the absence of disease only. A critical development of Heidegger's position can provide us with a criterion for distinguishing the uses of medical technologies that are compatible with such an endeavor from the technological projects that are not.

  5. The transcendence of time in the epistemology of observation from a phenomenological standpoint

    Directory of Open Access Journals (Sweden)

    Stathis Livadas

    2011-12-01

    Full Text Available In this article I deal with time as a notion of epistemological content associated though with the notion of a subjective consciousness co-constitutive of physical reality. In this phenomenologically grounded approach I attempt to establish a 'metaphysical' aspect of time, within a strictly epistemological context, in the sense of an underlying absolute subjectivity which is non-objectifiable within objective temporality and thus non-susceptible of any ontological designation. My arguments stem, on the one hand, from a version of quantum-mechanical theory (History Projection Operator theory, HPO theory in view of its formal treatment of two different aspects of time within a quantum context. The discrete, partial-ordering properties (the notions of before and after and the dynamical-parameter properties reflected in the wave equations of motion. On the other hand, to strengthen my arguments for a transcendental factor of temporality, I attempt an interpretation of some relevant conclusions in the work of J. Eccles ([5] and of certain results of experimental research of S. Deahaene et al. ([2] and others.

    The phenomenology of color scalar octet particles is discussed. Namely, the discovery potential of scalar octets at LEP, FNAL and LHC is discussed. It appears that new hadrons composed from scalar colour octets are rather longlived (Γ≤O(10) keV). The current experimental data don't contradict to the existence of light (M∼O(1) GeV) scalar octets. Light scalar colour octets give additional contribution to the QCD β-function and allow to improve agreement between deep inelastic and LEP data. 10 refs.; 2 figs

    A phenomenological model for nuclear multifragmentation is presented. It is made up of two complementary parts: molecular dynamics and restructured aggregation. It is applied to study the multifragmentation of 16 O+ 80 Br system at several bombarding energies. The results turn out to be in good agreement with available emulsion data. The production of charged particles and IMF as a function of the bombarding energy is also studied. The results seem to agree quite well with experimental observations and with previous results of other model calculations. (author) 19 refs.; 5 figs.; 1 tab

    The Porcupine caribou herd has traditionally used the coastal plain of the Arctic National Wildlife Refuge, Alaska, for calving. Availability of nutritious forage has been hypothesized as one of the reasons the Porcupine caribou herd migrates hundreds of kilometers to reach the coastal plain for calving (Kuropat and Bryant 1980, Russell et al. 1993).Forage quantity and quality and the chronology of snowmelt (which determines availability and phenological stages of forage) have been suggested as important habitat attributes that lead calving caribou to select one area over another (Lent 1980, White and Trudell 1980, Eastland et al. 1989). A major question when considering the impact of petroleum development is whether potential displacement of the caribou from the 1002 Area to alternate calving habitat will limit access to high quantity and quality forage.Our study had the following objectives: 1) quantify snowmelt patterns by area; 2) quantify relationships among phenology, biomass, and nutrient content of principal forage species by vegetation type; and 3) determine if traditional concentrated calving areas differ from adjacent areas with lower calving densities in terms of vegetation characteristics.

  9. Thinking of Identity as Self and Body. Recent Contributions from Phenomenology, Cognitive Studies, and Neuroscience

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available In recent years, phenomenology has increasingly engaged in dialogue with the cognitive sciences, the neurosciences, and psychopathology. In particular, the foci of this debate are: the structure of consciousness and conscious acts, the different forms of self-awareness, the inquiry concerning the self and its disturbances, and intersubjectivity. Two recent volumes bear witness to this flourishing debate. The first one, Body Memory, Metaphor, and Movement deals with the issue of embodied subjectivity and is particularly concerned with the phenomenon of implicit body memory and collects contributions from phenomenology, the cognitive sciences, and embodied therapies. The second one, The Oxford Handbook of the Self brings together contributions from phenomenological, cognitive, and psychopathological research and addresses the topic of the Self from the diverse standpoints expressed by these areas of studies. The issue of the Self is analyzed with regard to various perspectives such as bodily existence, the formation of personal identity, metaphysical inquiry, the moral dimension and the pathologies of the self. The essay aims to provide a critical assessment of these volumes and to discuss their theoretical impact on current phenomenological and cognitive research.

    Full Text Available In the article sights of founders of existential psychology at phenomenology and psychological mechanisms of intrapersonal conflicts are considered. It is underlined, that the basic internal conflict is connected with existential anxiety, human life-death. Experience of the existence in the modern social world often has tragical character for the person. The solution of existential intrapersonal conflicts is defined by how the person could realize in itself deep «Me» connected with feeling of finding of internal and external freedom, creative and spontaneity. It is emphasized, that freedom is the main quality of social human life, but the way to it demands from the person of the responsibility, courage and honesty. The authorship of own destiny, personal identity are a source of the solution of existential intrapersonal conflicts. Not each person is capable to keep authenticity in the life. Integrity «Me» cannot be restored, ignoring cultural mental-moral values. Purpose. To study phenomenology and psychological mechanisms of the solution of existential intrapersonal conflicts. Methodology. The qualitative theoretical analysis and synthesis of literary data. Results. In the article general concepts of leading scientists-psychologists of existential orientation to phenomenology and mechanisms of the solution of intrapersonal conflicts are presented.

  15. Contribution to the prediction of sodium-water reactions effects: application to confinement losses inside a steam generator building of a sodium fast reactor

    Daudin, Kevin

    2015-01-01

    Study of sodium-water reaction (SWR) consequences in open air represents a challenge in the frame of safety assessments of sodium fast reactors (SFR). In case of major accident and to predict consequences of SWR, it is necessary to better appreciate phenomena and especially quantity and rate of the energy release. The objective is thus to strengthen the understanding of such reactions in order to predict with lore accuracy its consequences on mechanical equipment in the surroundings. This work focuses on three areas : research of accidental sequences, experimental investigation, and phenomenological analysis before the explosive contact. At first, a tree structure risk analysis with calculations of dangerous phenomena permitted to suggest how the contact between reactants may happen. Then, demonstrative experimental studies were performed to deepen some practical aspects of the phenomenology, like the influence of the way the reactants get in contact. Data analysis conducted to the development of a phenomenological model, implemented into a software platform for numerical simulations. Although numerous hypothesis, transient heat transfer consideration enables to reproduce experimental observations, especially the influence of mixing conditions (sodium mass and initial temperatures) on the phenomenology. This study of the premixing step of sodium-water explosion is relevant in the frame of current prediction methods of mechanical loadings on structures. (author) [fr

  16. A conserved quantity in thin body dynamics

    Hanna, J. A.; Pendar, H.

    2016-02-01

    Thin, solid bodies with metric symmetries admit a restricted form of reparameterization invariance. Their dynamical equilibria include motions with both rigid and flowing aspects. On such configurations, a quantity is conserved along the intrinsic coordinate corresponding to the symmetry. As an example of its utility, this conserved quantity is combined with linear and angular momentum currents to construct solutions for the equilibria of a rotating, flowing string, for which it is akin to Bernoulli's constant.

  18. A phenomenological case study concerning science teacher educators' beliefs and teaching practices about culturally relevant pedagogy and preparing K-12 science teachers to engage African American students in K-12 science

    Science.gov (United States)

    Underwood, Janice Bell

    Due to the rising diversity in today's schools, science teacher educators (STEs) suggest that K-12 teachers must be uniquely prepared to engage these students in science classrooms. Yet, in light of the increasing white-black science achievement gap, it is unclear how STEs prepare preservice teachers to engage diverse students, and African Americans in particular. Therefore, the purpose of this study was to find out how STEs prepare preservice teachers to engage African American students in K-12 science. Thus, using the culturally relevant pedagogy (CRP) framework, this phenomenological case study explored beliefs about culturally relevant science teaching and the influence of reported beliefs and experiences related to race on STEs' teaching practices. In the first phase, STE's in a mid-Atlantic state were invited to participate in an electronic survey. In the second phase, four participants, who were identified as exemplars, were selected from the survey to participate in three semi-structured interviews. The data revealed that STEs were more familiar with culturally responsive pedagogy (CResP) in the context of their post-secondary classrooms as opposed to CRP. Further, most of the participants in part one and two described modeling conventional ways they prepare their preservice teachers to engage K-12 students, who represent all types of diversity, without singling out any specific race. Lastly, many of the STEs' in this study reported formative experiences related to race and beliefs in various manifestations of racism have impacted their teaching beliefs and practices. The findings of this study suggest STEs do not have a genuine understanding of the differences between CRP and CResP and by in large embrace CResP principles. Secondly, in regards to preparing preservice teachers to engage African American students in science, the participants in this study seemed to articulate the need for ideological change, but were unable to demonstrate pedagogical changes

  1. Optimal trading quantity integration as a basis for optimal portfolio management

    Directory of Open Access Journals (Sweden)

    Saša Žiković

    2005-06-01

    Full Text Available The author in this paper points out the reason behind calculating and using optimal trading quantity in conjunction with Markowitz’s Modern portfolio theory. In the opening part the author presents an example of calculating optimal weights using Markowitz’s Mean-Variance approach, followed by an explanation of basic logic behind optimal trading quantity. The use of optimal trading quantity is not limited to systems with Bernoulli outcome, but can also be used when trading shares, futures, options etc. Optimal trading quantity points out two often-overlooked axioms: (1 a system with negative mathematical expectancy can never be transformed in a system with positive mathematical expectancy, (2 by missing the optimal trading quantity an investor can turn a system with positive expectancy into a negative one. Optimal trading quantity is that quantity which maximizes geometric mean (growth function of a particular system. To determine the optimal trading quantity for simpler systems, with a very limited number of outcomes, a set of Kelly’s formulas is appropriate. In the conclusion the summary of the paper is presented.

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

    Science.gov (United States)

    Pooler, Charlotte

    2014-01-01

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

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

    Science.gov (United States)

    Murray, Stuart J; Holmes, Dave

    2013-07-01

    Working within the tradition of continental philosophy, this article argues in favour of a phenomenological understanding of language as a crucial component of bioethical inquiry. The authors challenge the 'commonsense' view of language, in which thinking appears as prior to speaking, and speech the straightforward vehicle of pre-existing thoughts. Drawing on Maurice Merleau-Ponty's (1908-1961) phenomenology of language, the authors claim that thinking takes place in and through the spoken word, in and through embodied language. This view resituates bioethics as a matter of bodies that speak. It also refigures the meaning of ethical self-reflexion, and in so doing offers an alternative view on reflexivity and critique. Referring to the Kantian critical tradition and its reception by Hannah Arendt and Michel Foucault, we advance a position we call 'critical ethical reflexivity'. We contend that Merleau-Ponty's phenomenology of language offers valuable insight into ethical reflexivity and subject formation. Moreover, his understanding of language may foster new qualitative empirical research in bioethics, lead to more nuanced methods for interpreting personal narratives, and promote critical self-reflexion as necessary for bioethical inquiry. © 2013 John Wiley & Sons Ltd.

    Worrying is the central feature of generalized anxiety disorder (GAD). Many people worry from time to time, but in GAD the worrying is prolonged and difficult to control. Worrying is a specific way of coping with perceived threats and feared situations. Meanwhile, it is not considered to be a helpful coping strategy, and the phenomenological account developed in this paper aims to show why. It builds on several phenomenological notions and in particular on Michael Wheeler's application of the...

  6. SLED phenomenology: curvature vs. volume

    International Nuclear Information System (INIS)

    Niedermann, Florian; Schneider, Robert

    2016-01-01

    We assess the question whether the SLED (Supersymmetric Large Extra Dimensions) model admits phenomenologically viable solutions with 4D maximal symmetry. We take into account a finite brane width and a scale invariance (SI) breaking dilaton-brane coupling, both of which should be included in a realistic setup. Provided that the brane tension and the microscopic size of the brane take generic values set by the fundamental bulk Planck scale, we find that either the 4D curvature or the size of the extra dimensions is unacceptably large. Since this result is independent of the dilaton-brane couplings, it provides the biggest challenge to the SLED program. In addition, to quantify its potential with respect to the cosmological constant problem, we infer the amount of tuning on model parameters required to obtain a sufficiently small 4D curvature. A first answer was recently given in http://dx.doi.org/10.1007/JHEP02(2016)025, showing that 4D flat solutions are only ensured in the SI case by imposing a tuning relation, even if a brane-localized flux is included. In this companion paper, we find that the tuning can in fact be avoided for certain SI breaking brane-dilaton couplings, but only at the price of worsening the phenomenological problem. Our results are obtained by solving the full coupled Einstein-dilaton system in a completely consistent way. The brane width is implemented using a well-known ring regularization. In passing, we note that for the couplings considered here the results of http://dx.doi.org/10.1007/JHEP02(2016)025 (which only treated infinitely thin branes) are all consistently recovered in the thin brane limit, and how this can be reconciled with the concerns about their correctness, recently brought up in http://dx.doi.org/10.1007/JHEP01(2016)017.

  7. Dark matter phenomenology of SM and enlarged Higgs sectors extended with vector-like leptons.

    Science.gov (United States)

    Angelescu, Andrei; Arcadi, Giorgio

    2017-01-01

    We will investigate the scenario in which the Standard Model (SM) Higgs sector and its two-doublet extension (called the Two Higgs Doublet Model or 2HDM) are the "portal" for the interactions between the Standard Model and a fermionic Dark Matter (DM) candidate. The latter is the lightest stable neutral particle of a family of vector-like leptons (VLLs). We will provide an extensive overview of this scenario combining the constraints coming purely from DM phenomenology with more general constraints like Electroweak Precision Test (EWPT) as well as with collider searches. In the case that the new fermionic sector interacts with the SM Higgs sector, constraints from DM phenomenology force the new states to lie above the TeV scale. This requirement is relaxed in the case of 2HDM. Nevertheless, strong constraints coming from EWPTs and the Renormalization Group Equations (RGEs) limit the impact of VLFs on collider phenomenology.

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

    Science.gov (United States)

    Rosen, Steven M

    2017-12-01

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

  10. A Method for Developing Enterprise Architecture Frameworks: An Interpretive Phenomenology Study

    Directory of Open Access Journals (Sweden)

    Ali Moeini

    2015-03-01

    Full Text Available Nowadays, many of organizations, who are involved in enterprise architecting, make their own architecture framework or customize existing frameworks. These endeavors are based on the knowledge and the experience of each organization, and there is no defined method for developing the enterprise architecture framework. Therefore, a method for developing architecture framework is presented in this qualitative research. For this reason, 15 versions of 5 most used architecture frameworks are analyzed based on the interpretive phenomenology. Based on this analysis, a method for developing architecture frameworks is introduced which contains 8 disciplines and 6 phases. Analyzing the qualitative data of the research and also the validation of the research are carried out using the guidelines of Van Manen in the interpretive phenomenology.

  11. Impact of age-relevant goals on future thinking in younger and older adults.

    Science.gov (United States)

    Lapp, Leann K; Spaniol, Julia

    2017-10-01

    This study investigated how personal goals influence age differences in episodic future thinking. Research suggests that personal goals change with age and like autobiographical memory, future thinking is thought to be organised and impacted by personal goals. It was hypothesised that cueing older adults with age-relevant goals should modulate age differences in episodic details and may also influence phenomenological characteristics of imagined scenarios. Healthy younger and older adults completed the Future Thinking Interview [Addis, D. R., Wong, A. T., & Schacter, D. L. (2008). Age-related changes in the episodic simulation of future events. Psychological Science, 19(1), 33-41. doi: 10.1111/j.1467-9280.2008.02043.x ] adapted to activate age-appropriate goals. Narratives were scored with an established protocol to obtain objective measures of episodic and semantic details. Subjective features such as emotionality and personal significance showed age differences as a function of goal domain while other features (e.g., vividness) were unaffected. However, consistent with prior reports, older adults produced fewer episodic details than younger adults and this was not modulated by goal domain. The results do not indicate that goal activation affects level of episodic detail. With respect to phenomenological aspects of future thinking, however, younger adults show more sensitivity to goal activation, compared with older adults.

    1985-01-01

    The ICRU Report 39 entitled ''Determination of Dose Equivalents Resulting from External Radiation Sources'' is briefly discussed. Four new operational dose equivalent quantities have been recommended in ICRU 39. The 'ambient dose equivalent' and the 'directional dose equivalent' are applicable to environmental monitoring and the 'individual dose equivalent, penetrating' and the 'individual dose equivalent, superficial' are applicable to individual monitoring. The quantities should meet the needs of day-to-day operational practice, while being acceptable to those concerned with metrological precision, and at the same time be used to give effective control consistent with current perceptions of the risks associated with exposure to ionizing radiations.

    2002-01-01

    To explore the prevalence, phenomenology, and background of leisure sickness, i.e., the condition of people developing symptoms of sickness during weekends and/or vacations. In order to obtain an estimate of its prevalence, a representative Dutch sample consisting of 1,128 men and 765 women was asked to indicate to what extent they recognized themselves in our description of weekend and vacation sickness. For the investigation of the phenomenology and background of this condition and the characteristics of the patients suffering from it, questionnaire data were collected in new samples consisting of 114 cases and 56 controls. Questions referred to symptoms, onset, duration, appreciation of weekend and vacation activities, and appraisal of work and workload. In the case of male respondents, 3.6 and 3.2% recognized themselves in the description of the weekend and the vacation syndrome, respectively, compared with 2.7 and 3.2% women. Most frequently reported symptoms were headache/migraine, fatigue, muscular pains, and nausea. In addition, viral infections (flue-like, common cold) were often reported in relation to vacations. Cases had generally suffered from leisure sickness for over 10 years and the onset was associated with stressful conditions. They attributed their condition to difficulties with the transition from work to nonwork, stress associated with travel and vacation, as well as workload and personality characteristics. There were no significant group differences in the appreciation of weekend and leisure activities or lifestyle during days off. Most striking differences were found with respect to experienced workload, sense of responsibility, and inability to relax. Leisure sickness is a relatively common condition. Specific lifestyle factors or leisure activities seem to be less relevant for its development. Concerning risk factors, the data tend to point to high workload and person characteristics, namely, the inability to adapt to the nonworking

    The aim of the study was to assess the correlation of Candida spp. incidence in periodontal tissues with various clinical manifestations of chronic periodontal disease (CPD). Ninety patients with CPD were included in the study in which Candida spp. was evaluated in periodontal pockets content and gingival biopsy material. In severe CPD more Candida spp. were seen in gingival biopsy than in periodontal pockets (p=0.0006). Candida spp. incidence and quantity correlated directly with the disease grade showing incidence increase from 40 to 73.3% and quantity increase from 0.8±0.18 до 3.6±0.49 lg CFU/ml in light and severe CPD, correspondingly Candida spp. had statistically significant association with cyanotic gingival color (p=0.0018), tongue plaque and swelling (р=0.0042), lip exfoliation (р=0.0030), periodontal pockets depth >5 mm (р=0.0030), oral mucosa hyperemia (р=0.0157), alveolar bone destruction >1/2 of root length (р=0.0157). These data prove the relevance of Candida spp. and mycological assessment of gingival biopsy in CPD patients.

  1. The Emancipation of the Preface in the "Phenomenology of Spirit"

    Full Text Available In his work Prefaces, Kierkegaard’s pseudonym Nicolaus Notabene refers satirically to the preface of Hegel’s Phenomenology of Spirit, claiming the value of a preface beyond its connection with the book, against the hegelian objections to prefaces. The present paper aims to compare both works in order to reconsider the relation between them, proposing and alternative interpretation according to which Kierkegaard’s book, beyond its ironical nature, can be regarded as an explicit statement of the inherent meaning to Hegel’s critique of prefaces carried out in the very preface to the Phenomenology of Spirit. Thus Notabene’s satire will help to identify the hegelian preface as an “emancipated preface”, just as Kierkegaard’s heteronym describes them, as texts whose real meaning would consist in its ability to operate exclusively as a disposition [Stemning / Stimmung] towards the work that they precede.

  2. Dark matter phenomenology of SM and enlarged Higgs sectors extended with vector-like leptons

    We will investigate the scenario in which the Standard Model (SM) Higgs sector and its two-doublet extension (called the Two Higgs Doublet Model or 2HDM) are the ''portal'' for the interactions between the Standard Model and a fermionic Dark Matter (DM) candidate. The latter is the lightest stable neutral particle of a family of vector-like leptons (VLLs). We will provide an extensive overview of this scenario combining the constraints coming purely from DM phenomenology with more general constraints like Electroweak Precision Test (EWPT) as well as with collider searches. In the case that the new fermionic sector interacts with the SM Higgs sector, constraints from DM phenomenology force the new states to lie above the TeV scale. This requirement is relaxed in the case of 2HDM. Nevertheless, strong constraints coming from EWPTs and the Renormalization Group Equations (RGEs) limit the impact of VLFs on collider phenomenology.

  3. Generalized anxiety disorder and online intelligence: a phenomenological account of why worrying is unhelpful.

    Science.gov (United States)

    Meynen, Gerben

    2011-05-03

    Worrying is the central feature of generalized anxiety disorder (GAD). Many people worry from time to time, but in GAD the worrying is prolonged and difficult to control. Worrying is a specific way of coping with perceived threats and feared situations. Meanwhile, it is not considered to be a helpful coping strategy, and the phenomenological account developed in this paper aims to show why. It builds on several phenomenological notions and in particular on Michael Wheeler's application of these notions to artificial intelligence and the cognitive sciences. Wheeler emphasizes the value of 'online intelligence' as contrasted to 'offline intelligence'. I discuss and apply these concepts with respect to worrying as it occurs in GAD, suggesting that GAD patients overrate the value of detached contemplation (offline intelligence), while underrating their embodied-embedded adaptive skills (online intelligence). I argue that this phenomenological account does not only help explaining why worrying is used as a coping strategy, but also why cognitive behavioral therapy is successful in treating GAD.

    2007-01-01

    Many dosimetric quantities have been used for radiation protection purpose. The International Commission on Radiological Protection (ICRP) has recommended protection quantities and the International Commission on Radiation Units and Measurements (ICRU) has introduced operational quantities to provide a reasonable estimate of the protection quantities. Enthusiastic discussions are continuously made on the issues of the dosimetric quantities, such as basic biological data for the definition of these quantities and applicability of the quantities to actual radiation protection practice. At the moment, some changes are being proposed concerning dosimetric quantities in the draft recommendations of ICRP, opened for consultation in recent years. Thus, the Japan Health Physics Society (JHPS) established the Expert Committee on concepts of Dosimetric Quantities used in radiological protection (ECDQ) in April 2005 to reviewed and discuss issues in the dosimetric quantities.

  7. The body as constitutive element phenomenology and psychoanalysis on our view of ourselves and others.

    Science.gov (United States)

    Monjaraz Fuentes, Paulina; Rojas Hernández, María Del Carmen; Santasilia, Stefano; Monjaraz Fuentes, Fernanda

    2017-12-01

    The aim of this manuscript is to highlight that from the phenomenology and psychoanalysis point of view, the meaning of the notion of the body is different from the medical biologicist discourse. In psychoanalysis, the body is an erogenized body. It is constituted as an object for another self. Similarly, in phenomenology, the body is an own body in first instance. It is the body of a self, rather than a living body and a material body. Both positions enable us to understand how this conceptualization of the body is essential in any human field. Especially in the clinic, the position of the subject before the other will lead to a specific form of intervention. From this understanding of the human body, both phenomenology and psychoanalysis confirm that the biologicist understanding of the body, presumed by all psychological and medical practices, is insufficient.

    Within the phenomenological tradition, one frequently finds the bold claim that interpersonal understanding is rooted in a sui generis form of intentional experience, most commonly labeled empathy (Einfühlung). The following paper explores this claim, emphasizing its distinctive character......, and examining the phenomenological considerations offered in its defense by two of its main proponents, Edmund Husserl and Edith Stein. After offering in section 2 some preliminary indications of how empathy should be understood, I then turn to some characterizations of its distinctive structure, considering......, in section 3, the Husserlian claim that certain forms of empathy are perceptual in nature, and in section 4, Stein’s insistence that empathetic experience frequently involves explicating the other’s own intentional experiences.

    : the larger the simulated sewer network, the smoother the simulated diurnal flow rate and concentration variations. In the discussion, it is pointed out how the proposed phenomenological models can be expanded to other applications, for example to represent heavy metal or organic micro-pollutant loads......Activated Sludge Models are widely used for simulation-based evaluation of wastewater treatment plant (WWTP) performance. However, due to the high workload and cost of a measuring campaign on a full-scale WWTP, many simulation studies suffer from lack of sufficiently long influent flow rate...... and concentration time series representing realistic wastewater influent dynamics. In this paper, a simple phenomenological modelling approach is proposed as an alternative to generate dynamic influent pollutant disturbance scenarios. The presented set of models is constructed following the principles of parsimony...

  11. Phenomenology of the gauge symmetry for right-handed fermions

    Chao, Wei

    2018-02-01

    In this paper we investigate the phenomenology of the U(1) gauge symmetry for right-handed fermions, where three right-handed neutrinos are introduced for anomalies cancellations. Constraints on the new gauge boson Z_{R} from Z-Z^' mixing as well as the upper bound of Z^' production cross section in di-lepton channel at the LHC are presented. We further study the neutrino mass and the phenomenology of Z_{R}-portal dark matter in this model. The lightest right-handed neutrino can be the cold dark matter candidate stabilized by a Z_2 flavor symmetry. Our study shows that active neutrino masses can be generated via the modified type-II seesaw mechanism; right-handed neutrino is available dark matter candidate for its mass being very heavy, or for its mass at near the resonant regime of the SM Higgs and(or) the new bosons; constraint from the dilepton search at the LHC is stronger than that from the Z-Z^' mixing only for g_{R}<0.121, where g_{R} is the new gauge coupling.

  17. Dosimetric radiation protection quantities. Impact of the forthcoming ICRP recommendations

    International Nuclear Information System (INIS)

    Pradhan, A.S.; Lee, J.I.; Kim, J.L.; Kim, B.H.

    2008-01-01

    The physical quantities namely fluence, kerma and absorbed dose provide the base for the operational and the protection quantities. The absorbed dose continues to be the fundamental physical quantity for the radiological protection. The most striking feature relating the quantities in the forthcoming recommendations is the updating of the radiation and tissue weighting factors based on the latest available scientific information on radiobiology and the physics of radiation exposure. This is bound to make a significant impact in arriving at the equivalent doses and effective dose. For external exposures of neutrons, the forthcoming recommendations are going to improve the relationship between the operational and protection quantities. The changes in the tissue weighting factors of some tissues/organs, the inclusion of several new tissues/organs for the consideration of tissue weighting factors and the use of the proposed Reference Male and Reference Female voxel phantoms would require new conversion coefficients and dose coefficients for external and internal exposures. The other striking feature appears to be the details of the concepts to ensure that the protections quantities are used for the appropriate and intended purposes only and the misuse is avoided.

    Research in theoretical elementary particle physics was performed by the PI Yannick Meurice and co-PI Mary Hall Reno. New techniques designed for precision calculations of strong interaction physics were developed using the tensor renormalization group method. Large-scale Monte Carlo simulations with dynamical quarks were performed for candidate models for Higgs compositeness. Ab-initio lattice gauge theory calculations of semileptonic decays of B-mesons observed in collider experiments and relevant to test the validity of the standard model were performed with the Fermilab/MILC collaboration. The phenomenology of strong interaction physics was applied to new predictions for physics processes in accelerator physics experiments and to cosmic ray production and interactions. A research focus has been on heavy quark production and their decays to neutrinos. The heavy quark contributions to atmospheric neutrino and muon fluxes have been evaluated, as have the neutrino fluxes from accelerator beams incident on heavy targets. Results are applicable to current and future particle physics experiments and to astrophysical neutrino detectors such as the IceCube Neutrino Observatory.

    Full Text Available During recent centuries, under the influence of modern and postmodern ideas, religious studies have been exposed to new approaches and views. On the one hand, these approaches are not an extension of theology in the traditional sense and on the other hand, they give a remarkable role to method in religious studies. The importance of phenomenology and the eyes it has caught as a "method" in study of religion, as well as in such disciplines as philosophy of religion, sociology of religion, psychology of religion, history of religion  and so on,‌ have been due to the compatibility of this method or approach with different religions and as a result due to preparing the ground for comparative studies of religions, on the one hand, and because of being descriptive and non-judicative about beliefs and thoughts, on the other. Historically speaking, this method or approach is a product of the mixture of two intellectual currents in the nineteenth century west. These two currents comprise scientific research of religion and the philosophical phenomenology of the German philosopher, "Edmund Husserl". As compared to philosophical phenomenology, phenomenology of religion has undergone through dramatic changes in all its aspects. But we can't understand phenomenology of religion, particularly in the twentieth century, apart from philosophical phenomenology, specifically Husserl's phenomenology and its important concepts.

  2. Levels of reduction in van Manen's phenomenological hermeneutic method: an empirical example.

    Heinonen, Kristiina

    2015-05-01

    To describe reduction as a method using van Manen's phenomenological hermeneutic research approach. Reduction involves several levels that can be distinguished for their methodological usefulness. Researchers can use reduction in different ways and dimensions for their methodological needs. A study of Finnish multiple-birth families in which open interviews (n=38) were conducted with public health nurses, family care workers and parents of twins. A systematic literature and knowledge review showed there were no articles on multiple-birth families that used van Manen's method. Discussion The phenomena of the 'lifeworlds' of multiple-birth families consist of three core essential themes as told by parents: 'a state of constant vigilance', 'ensuring that they can continue to cope' and 'opportunities to share with other people'. Reduction provides the opportunity to carry out in-depth phenomenological hermeneutic research and understand people's lives. It helps to keep research stages separate but also enables a consolidated view. Social care and healthcare professionals have to hear parents' voices better to comprehensively understand their situation; they need further tools and training to be able to empower parents of twins. This paper adds an empirical example to the discussion of phenomenology, hermeneutic study and reduction as a method. It opens up reduction for researchers to exploit.

    Band-Winterstein, Tova

    2015-01-01

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

  4. Quantum groups in hadron phenomenology

    1997-01-01

    We show that application of quantum unitary groups, in place of ordinary flavor SU(n f ), to such static aspects of hadron phenomenology as hadron masses and mass formulas is indeed fruitful. So-called q-deformed mass formulas are given for octet baryons 1/2 + and decuplet baryons 3/2 + , as well as for the case of vector mesons 1 - involving heavy flavors. For deformation parameter q, rigid fixation of values is used. New mass sum rules of remarkable accuracy are presented. As shown in decuplet case, the approach accounts for effects highly nonlinear in SU(3)-breaking. Topological implication (possible connection with knots) for singlet vector mesons and the relation q ↔ Θ c (Cabibbo angle) in case of baryons are considered

    Kobiela Filip

    2015-06-01

    Full Text Available The paper addresses the family of questions that arose from the field of interactions between phenomenology and the cognitive sciences. On the one hand, apparently partial coextensivity of research domain of phenomenology and the cognitive sciences sets the goal of their cooperation and mutual inspiration. On the other hand, there are some obstacles on the path to achieve this goal: phenomenology and the cognitive sciences have different traditions, they speak different languages, they have adopted different methodological approaches, and last but not least, their prominent exponents exhibits different styles of thinking. In order to clarify this complicated area of tensions, the paper presents the results of philosophical reflections of such topics as: 1 philosophical presuppositions and postulates of the cognitive sciences 2 abstraction of some phenomena during idealisation and the dialectical model of science's development 3 argumentation based on prediction of future development of the cognitive sciences. This finally leads to the formulation of a phenomenology-based postulate for adequate model of mind and the discussion of humanistic dimension of cognitive sciences.

    The numerical results obtained in the interpretation of individual monitoring of external radiation depend not only on the accurate calibration of the radiation measurement instruments involved, but also on the definition of the quantities in term of which these instruments are calibrated The absence of uniformity in terminology not only makes it difficult to understand properly the scientific and technical literature but can also lead to incorrect interpretation of particular concepts and recommendations. In this paper, brief consideration is given to definition of radiation quantities and terminology used in calibration procedures. (author)

    2014-08-01

    Recently, white striations parallel to muscle fibers direction have been observed on the surface of chicken breast, which could be ascribed to intensive growth selection. The aim of this study was to evaluate the effect of white striping on chemical composition with special emphasis on myofibrillar and sarcoplasmic protein fractions that are relevant to the processing features of chicken breast meat. During this study, a total of 12 pectoralis major muscles from both normal and white striped fillets were used to evaluate chemical composition, protein solubility (sarcoplasmic, myofibrillar, and total protein solubility), protein quantity (sarcoplasmic, myofibrillar, and stromal proteins), water holding capacity, and protein profile by SDS-PAGE analysis. White-striped fillets exhibited a higher percentage of moisture (75.4 vs. 73.8%; P cooking loss (33.7 vs. 27.4%; P chicken breast meat with white striping defect had different chemical composition (more fat and less protein) and protein quality and quantity (low content of myofibrillar proteins and high content of stromal proteins) with respect to normal meat. Furthermore, white striped fillets had lower protein functionality (higher cooking loss). All the former changes indicate that white striping has great impact on quality characteristics of chicken breast meat. © Poultry Science Association Inc.

    Energy Technology Data Exchange (ETDEWEB)

    Gaillard, Mary K., E-mail: mkgaillard@lbl.gov

    2016-11-15

    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.

    Freud's metapsychology is the subject of an important debate. This is over whether psychoanalysis is best construed as a science of the natural science type or as a special human science. The same debate applies to Melanie Klein's work. In Klein's metapsychology are two different and incompatible models of explanation. One is taken over from Freud's structural theory and appears to be similarly mechanistic. The other is clinically based and phenomenological. These two are discussed with special reference to the concepts of "phantasy" and "internal object".

    Davidson, Michele R

    2004-09-01

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

    2007-01-01

    Seeking relevant criteria for testing the quality of turbulence models, the scale of turbulence and the gust factor have been estimated from data and compared with predictions from first-order models of these two quantities. It is found that the mean of the measured length scales is approx. 10......% smaller than the IEC model, for wind turbine hub height levels. The mean is only marginally dependent on trends in time series. It is also found that the coefficient of variation of the measured length scales is about 50%. 3sec and 10sec pre-averaging of wind speed data are relevant for MW-size wind...... turbines when seeking wind characteristics that correspond to one blade and the entire rotor, respectively. For heights exceeding 50-60m the gust factor increases with wind speed. For heights larger the 60-80m, present assumptions on the value of the gust factor are significantly conservative, both for 3...

    We investigate the phenomenology of Composite 2-Higgs doublet models (C2HDMs) of various Yukawa types based on the global symmetry breaking SO(6) → SO(4) x SO(2). The kinetic part and the Yukawa Lagrangian are constructed in terms of the pseudo Nambu-Goldstone Boson (pNGB) matrix and a 6-plet of fermions under SO(6). The scalar potential is assumed to be the same as that of the Elementary 2-Higgs doublet model (E2HDM) with a softly broken discrete Z{sub 2} symmetry. We then discuss the phenomenological differences between the E2HDM and C2HDM by focusing on the deviations from standard model (SM) couplings of the discovered Higgs state (h) as well as on the production cross sections and branching ratios (BRs) at the large Hadron collider (LHC) of extra Higgs bosons. We find that, even if the same deviation in the hVV (V = W,Z) coupling is assumed in the two scenarios, there appear significant differences between the E2HDM and C2HDM from the structure of the Yukawa couplings, so that production and decay features of extra Higgs bosons can be used to distinguish between the two scenarios.

    Various solutions have been proposed for improving the combustion process of conventional diesel engines and reducing the exhaust emissions without making serious modifications on the engine, one of which is the use of natural gas as a supplement for the conventional diesel fuel, the so called dual fuel natural gas diesel engines. The most common type of these is referred to as the pilot ignited natural gas diesel engine (PINGDE). Here, the primary fuel is natural gas that controls the engine power output, while the pilot diesel fuel injected near the end of the compression stroke auto-ignites and creates ignition sources for the surrounding gaseous fuel mixture to be burned. Previous research studies have shown that the main disadvantage of this dual fuel combustion is its negative impact on engine efficiency compared to the normal diesel operation, while carbon monoxide emissions are also increased. The pilot diesel fuel quantity and injection advance influence significantly the combustion mechanism. Then, in order to examine the effect of these two parameters on the performance and emissions, a comprehensive two-zone phenomenological model is employed and applied on a high-speed, pilot ignited, natural gas diesel engine located at the authors' laboratory. According to the results, the simultaneously increase of the pilot fuel quantity accompanied with an increase of its injection timing results to an improvement of the engine efficiency (increase) and of the emitted CO emissions (decrease) while it has a negative effect (increase) of NO emissions

    Compares various methods of defining derived quantities, arguing for a definitional formula using base or fundamental units in a word equation, or symbol-equations with the symbols explained. Suggests that fundamental units be defined operationally or left regarded as intuitive as in the case of length and time. (JM)

  16. On Judith Butler: A Phenomenology of Lived, narrated and Represented Embodiment

    Full Text Available In this paper we take Judith Butler’s thinking as a basis from which to consider the ideas of three authors. In our view, these authors complement Butler’s project of helping excluded people to fight for a dignified life, a “liveable life”; and specifically to the idea of using performative resignifications of discourses and practices. On one hand, we present the writings of Sarah Ahmed and Lanei Rodemeyer; they consider the spatiality and temporality of the lived body (Ahmed and the relationship between the lived body and discourse (Rodemeyer. In both cases, “pure phenomenology” (and not hermeneutics is applied to the question of sexual diversity. On the other hand, we delve into the works of Louise Bourgeois, for whom artistic creation is a way of exorcising pain and becoming free of socially constructed prisons. Starting from the paths opened by these authors, we believe that a phenomenology is possible in which there is place for what does not fit into the norm. this phenomenology would make it possible, on one side, to rend visibility to those who do not fit into the established norms and categories and, on another side, to contribute to a reformulation of discourse, such a transformation that allows the excluded to inhabit them. “Pure” phenomenology, that aims at going to “the things themselves” do not naturalise oppressions, but it is rather an ally to recognise, denounce and provide a reparation for them.

    This study is a part of a larger project in which the aim is to illuminate the meaning of the caring relationship between patients and nurses in daily nursing practice. Empirical studies in this area inspired from the interpretive phenomenological method are not commonly used. The aim of this paper is to describe how an interpretive phenomenological method was used to illuminate the meaning of the phenomenon caring relationship in daily nursing practice. Data were collected during 16 nursing care proceedings using participant observation with field notes, and in addition to that two interviews, one patient and one nurse. The interpretation moved back and forth between the whole and the parts in a dialectic process. Initial interpretive understanding of interviews and field notes, meaning units and comprehensive understanding were presented. Themes from the patient's interviews were competence, lack of continuity, strain and vulnerability. Themes from the nurse's interviews were competence and striving. Themes from the field notes were interactions towards a goal. The use of interpretive phenomenology offered an opportunity for learning to understand the meaning of the phenomenon caring relationship in daily nursing practice with both strengths and limitations. This study gave an understanding of the phenomenon through the illumination of the patient's and the nurse's thoughts, feelings and actions in the nursing care proceedings that led to a more profound knowledge about how they together create an encounter through their unique competence.

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

  19. Detection Dynamics Of Nitrogen Based Explosive Quantities In Selected Cylindrical Containers

    Full Text Available An experimental set up for examining the variation of detection intensity with explosive quantity has been studied. Containers made from ceramic carbon steel wood and HDPE were filled with explosive masses ranging from 10 kg to 500 kg and irradiated by a 14.1 MeV point isotropic neutron source. The resulting gamma photons were analyzed for their C N and O composition and the sum computed to yield a quantity known as the material quotient MQ. Examination of MQ values indicates an initial increase in detection intensity with increasing explosive quantity. Saturation is however reached at an explosive quantity of about 25kg where detection intensity reduces with further increase in explosive quantity. Effects of variation in explosive quantity appeared to be more pronounced for explosives contained in HDPE and wooden containers and least pronounced for those in steel containers. Source-detector configuration was identified as a major factor affecting effective detection of large masses of explosives.
