    The 'Severe Accident Phenomenology Short Course' is part of the Excellence Spreading activities of the European Severe Accident Research NETwork of Excellence SARNET (project of the EURATOM 6. Framework programme). It was held at Cadarache, 9-13 January 2006. The course was divided in 14 lectures covering all aspects of severe accident phenomena that occur during a scenario. It also included lectures on PSA-2, Safety Assessment and design measures in new LWR plants for severe accident mitigation (SAM). This book presents the lecture notes of the Severe Accident Phenomenology Short Course and condenses the essential knowledge on severe accident phenomenology in 2008. (authors)

    In order to optimise the use of the available means and to constitute sustainable research groups in the European Union, the Severe Accident Research NETwork of Excellence (SARNET) has gathered 51 organisations representing most of the actors involved in Severe Accident (SA) research in Europe plus Canada. This project was co-funded by the European Commission (EC) under the 6th Euratom Framework Programme. Its objective was to resolve the most important pending issues for enhancing, in regard of SA, the safety of existing and future Nuclear Power Plants (NPPs). SARNET tackled the fragmentation that existed between the national R and D programmes, in defining common research programmes and developing common computer codes for safety assessment. The Joint Programme of Activities consisted in: (i) Implementing an advanced communication tool for accessing all project information, fostering exchange of information, and managing documents; (ii) Harmonizing and re-orienting the research programmes, and defining new ones; (iii) Analyzing the experimental results provided by research programmes in order to elaborate a common understanding of relevant phenomena; (iv) Developing the ASTEC code (integral computer code used to predict the NPP behaviour during a postulated SA) by integrating the knowledge produced within SARNET; (v) Developing Scientific Databases, in which the results of research experimental programmes are stored in a common format; (vi) Developing a common methodology for Probabilistic Safety Assessment of NPPs; (vii) Developing short courses and writing a text book on Severe Accidents for students and researchers; (viii) Promoting personnel mobility amongst various European organizations. This paper presents the major achievements after four and a half years of operation of the network, in terms of knowledge gained, of improvements of the ASTEC reference code, of dissemination of results and of integration of the research programmes conducted by the various

    Significant efforts are put into the assessment of the severe accident integral code ASTEC, jointly developed since several years by IRSN and GRS, either through comparison with results of the most important international experiments or through benchmarks with other severe accident simulation codes on plant applications. These efforts are done in first priority by the code developers’ organisations, IRSN and GRS, and also by numerous partners, in particular in the frame of the SARNET European network. The first version of the new series ASTEC V2 had been released in July 2009 to SARNET partners. Two subsequent V2.0 code revisions, including several modelling improvements, have been then released to the same partners, respectively in 2010 and 2011. This paper summarises first the approach of ASTEC validation vs. experiments, along with a description of the validation matrix, and presents then a few examples of applications of the ASTEC V2.0-rev1 version carried out in 2011 by the SARNET users. These calculation examples are selected in a way to cover diverse aspects of severe accident phenomenology, i.e. to cover both in-vessel and ex-vessel processes, in order to provide a good picture of the current ASTEC V2 capabilities. Finally, the main lessons drawn from this joint validation task are summarised, along with an evaluation of the current physical modelling relevance and thus an identification of the ASTEC V2.0 validity domain

    49 organisations network in SARNET (Severe Accident Research and management NETwork) their capacities of research in order to resolve the most important remaining uncertainties and safety issues for enhancing, in regard of Severe Accidents (SA), the safety of existing and future Nuclear Power Plants (NPPs). This project has been defined bearing in mind the necessity to optimise the use of the available means and to constitute sustainable research groups. SARNET tackles the fragmentation that exists between the different R and D national programmes, notably in defining common research programmes and developing common computer tools and methodologies for safety assessment. SARNET comprises most of the actors involved in SA research in Europe. To reach these objectives, all the organizations networked in SARNET contribute to a so-called Joint Programme of Activities (JPA), which can be broken in several elements: - Implementing an advanced communication tool for fostering exchange of information; - Harmonizing and re-orienting the research programmes, and defining commonly new ones; - Analysing commonly the experimental results provided by research programmes in order to elaborate a common understanding of concerned phenomena; - Developing ASTEC code (integral computer code used to predict the NPP behaviour during a postulated SA), which capitalizes in terms of physical models the knowledge produced within SARNET; - Developing Scientific Databases, in which all the results of research programmes are stored; - Developing a common methodology for Probabilistic Safety Assessment (PSA) of NNPs; - Developing educational courses and text (source) books; - Promoting personnel mobility between the various European organisations. A few organizations are covering a wide range of competences though not complete, whereas others are specialized in very specific areas and thus complementarities are developing.

    Within the SARNET Severe Accident Research Network of excellence, the Corium topic covers all the behaviour of corium (mixture formed by the molten materials arising from a postulated nuclear reactor severe accident) from early phase of core degradation to in or ex-vessel corium recovery with the exception of corium interaction with water, direct containment heating and fission product release. The Corium topic regroups in three work packages the critical mass of competence to improve significantly the corium behaviour knowledge. The spirit of the SARNET networking is to share the knowledge, the facilities and the simulation tools for severe accidents, so to reach a better efficiency and to rationalize the R and D effort at European level. Extensive benchmarking has been launched in most of the areas of research. These benchmarks were mainly dedicated to the recalculation of analytical experiments, integral experiments or reactor applications. Eventually, all the knowledge will be accumulated in the ASTEC severe accident simulation code through physical model improvements and extension of validation database. This report summarizes the progress that has been achieved in the frame of the networking activities for the four and half years of the FP6 project. (authors)

    Highlights: • The results of the benchmarking activity on wall condensation are reported. • The work was performed in the frame of SARNET. • General modelling techniques for condensation are discussed. • Results of University of Pisa and of other benchmark participants are discussed. • The lesson learned is drawn. - Abstract: The prediction of condensation in the presence of noncondensable gases has received continuing attention in the frame of the Severe Accident Research Network of Excellence, both in the first (2004–2008) and in the second (2009–2013) EC integrated projects. Among the different reasons for considering so relevant this basic phenomenon, coped with by classical treatments dated in the first decades of the last century, there is the interest for developing updated CFD models for reactor containment analysis, requiring validating at a different level the available modelling techniques. In the frame of SARNET, benchmarking activities were undertaken taking advantage of the work performed at different institutions in setting up and developing models for steam condensation in conditions of interest for nuclear reactor containment. Four steps were performed in the activity, involving: (1) an idealized problem freely inspired at the actual conditions occurring in an experimental facility, CONAN, installed at the University of Pisa; (2) a first comparison with experimental data purposely collected by the CONAN facility; (3) a second comparison with data available from experimental campaigns performed in the same apparatus before the inclusion of the activities in SARNET; (4) a third exercise involving data obtained at lower mixture velocity than in previous campaigns, aimed at providing conditions closer to those addressed in reactor containment analyses. The last step of the benchmarking activity required to change the configuration of the experimental apparatus to achieve the lower flow rates involved in the new test specifications. The

    Highlights: • Two similar QUENCH air ingress experiments were analysed with eight different codes. • Eight institutions have participated in the study. • Differences in the code were mostly small to moderate during the pre-oxidation. • Differences in the code were larger during the air phase. • Study has proven that there are physical processes that should be further studied. - Abstract: The QUENCH-10 (Q-10) and QUENCH-16 (Q-16) experiments were chosen as a SARNET2 code benchmark (SARNET2-COOL-D5.4) exercise to assess the status of modelling air ingress sequences and to compare the capabilities of the various codes used for accident analyses, specifically ATHLET-CD (GRS and RUB), ICARE-CATHARE (IRSN), MAAP (EDF), MELCOR (INRNE and PSI), SOCRAT (IBRAE), and RELAP/SCDAPSim (PSI). Both experiments addressed air ingress into an overheated core following earlier partial oxidation in steam. Q-10 was performed with extensive preoxidation, moderate/high air flow rate and high temperatures at onset of reflood (max T pct = 2200 K), while Q-16 was performed with limited preoxidation, low air flow rate and relative low temperatures at reflood initiation (max T pct = 1870 K). Variables relating to the major signatures (thermal response, hydrogen generation, oxide layer development, oxygen and nitrogen consumption and reflood behaviour) were compared globally and/or at selected locations. In each simulation, the same input models and assumptions are used for both experiments, differing only in respect of the boundary conditions. However, some slight idealisations were made to the assumed boundary conditions in order to avoid ambiguities in the code-to-code comparisons; in this way, it was possible to focus more easily on the key phenomena and hence make the results of the exercise more transparent. Remarks are made concerning the capability of physical modelling within the codes, description of the experiment facility and test conduct as specified in the code input

  13. SARNET. Severe Accident Research Network - key issues in the area of source term

    Giordano, P.; Micaelli, J.C.; Haste, T.; Herranz, L.

    2005-01-01

    About fifty European organisations integrate in SARNET (Network of Excellence of the EU 6 th Framework Programme) their research capacities in resolve better the most important remaining uncertainties and safety issues concerning existing and future Nuclear Power Plants (NPPs) under hypothetical Severe Accident (SA) conditions. Wishing to maintain a long-lasting cooperation, they conduct three types of activities: integrating activities, spreading of excellence and jointly executed research. This paper summarises the main results obtained by the network after the first year, giving more prominence to those from jointly executed research in the Source Term area. Integrating activities have been performed through different means: the ASTEC integral computer code for severe accident transient modelling, through development of PSA2 methodologies, through the setting of a structure for definition of evolving R and D priorities and through the development of a web-network of data bases that hosts experimental data. Such activities have been facilitated by the development of an Advanced Communication Tool. Concerning spreading of excellence, educational courses covering Severe Accident Analysis Methodology and Level 2 PSA have been set up, to be given in early 2006. A detailed text book on Severe Accident Phenomenology has been designed and agreed amongst SARNET members. A mobility programme for students and young researchers is being developed, some detachments are already completed or in progress, and examples are quoted. Jointly executed research activities concern key issues grouped in the Corium, Containment and Source Term areas. In Source Term, behaviour of the highly radio-toxic ruthenium under oxidising conditions (like air ingress) for HBU and MOX fuel has been investigated. First modelling proposals for ASTEC have been made for oxidation of fuel and of ruthenium. Experiments on transport of highly volatile oxide ruthenium species have been performed. Reactor

    2015-01-01

    Highlights: • Main achievements of source term research in SARNET are given. • Emphasis on the radiologically important iodine and ruthenium fission products. • Conclusions on FP release, transport in the RCS and containment behaviour. • Significance of large-scale integral experiments to validate the analyses used. • A thorough list of the most recent references on source term research results. - Abstract: Source Term has been one of the main research areas addressed within the SARNET network during the 7th EC Framework Programme of EURATOM. The entire source term domain was split into three major areas: oxidising impact on source term, iodine chemistry in the reactor coolant system and containment and data and code assessment. The present paper synthesises the main technical outcome stemming from the SARNET FWP7 project in the area of source term and includes an extensive list of references in which deeper insights on specific issues may be found. Besides, based on the analysis of the current state of the art, an outlook of future source term research is outlined, where major changes in research environment are discussed (i.e., the end of the Phébus FP project; the end of the SARNET projects; and the launch of HORIZON 2020). Most probably research projects will be streamlined towards: release and transport under oxidising conditions, containment chemistry, existing and innovative filtered venting systems and others. These will be in addition to a number of projects that have been completed or are ongoing under different national and international frameworks, like VERDON, CHIP and EPICUR started under the International Source Term Programme (ISTP), the OECD/CSNI programmes BIP, BIP2, STEM, THAI and THAI2, and the French national programme MIRE. The experimental PASSAM project under the 7th EC Framework programme, focused on source term mitigation systems, is highlighted as a good example of a project addressing potential enhancement of safety systems

    Full Text Available The SARNET2 (severe accidents Research NETwork of Excellence project started in April 2009 for 4 years in the 7th Framework Programme (FP7 of the European Commission (EC, following a similar first project in FP6. Forty-seven organisations from 24 countries network their capacities of research in the severe accident (SA field inside SARNET to resolve the most important remaining uncertainties and safety issues on SA in water-cooled nuclear power plants (NPPs. The network includes a large majority of the European actors involved in SA research plus a few non-European relevant ones. The “Education and Training” programme in SARNET is a series of actions foreseen in this network for the “spreading of excellence.” It is focused on raising the competence level of Master and Ph.D. students and young researchers engaged in SA research and on organizing information/training courses for NPP staff or regulatory authorities (but also for researchers interested in SA management procedures.

  18. Progress and perspectives of ASTEC applications in the European Network SARNET

    Van Dorsselaere, J.P.; Allelein, H.J.; Neu, K.

    2006-01-01

    The ASTEC integral code is jointly developed by IRSN (France) and GRS (Germany) for LWR source term Severe Accident (SA) evaluation, PSA level 2 studies and SA management evaluation. ASTEC constitutes now the reference European integral code through its role in the Network SARNET (Severe Accident Network of Excellence) in the EC 6. Framework Program. The models of next version V1.3, released before end of 2006, represent the current State of the Art, its validation is very extensive (in particular on Phebus FP) and, after next implementation of a model for reflooding of degraded cores, it will cover all needs for SA evaluation in PWR and VVER. It will be the reference code for the IRSN PSA level 2 (Probabilistic Safety Analysis) on French PWR 1300 MWe that starts in 2006. In the frame of SARNET, IRSN coordinates the ASTEC Topic gathering 30 partners that assess the code through validation against experiments and benchmarks with reference codes like CATHARE or RELAP5 for the reactor coolant circuit and COCOSYS for the containment. Plant application calculations are compared with MELCOR and MAAP4 results for a series of different SA sequences. Besides, the knowledge generated by SARNET Topics (Corium, Source Term and Containment) will be progressively integrated into the code through improved or new models. The 2. Users' Club organized at Aix-en-Provence in June 06, with 45 participants from 27 organizations, allowed fruitful discussions with the Maintenance Team. After 2 years of work, code validation shows good overall results, often close to results of reference codes. Some results reach the limits of present knowledge, for instance on Molten-Corium-Concrete-Interaction (MCCI) and Direct Containment Heating (DCH). Benchmarks on plant applications have been performed on diverse reactor types: PWR 900, Konvoi 1300, Westinghouse 1000, VVER-1000 and VVER-440. The main trends of results are similar to MELCOR or MAAP4 results. The objective of the quantitative

    Highlights: • SARNET network of excellence integration mid-2013 in the NUGENIA Association. • Progress of knowledge on corium behaviour, hydrogen explosion and source term. • Further development of ASTEC integral code to capitalize knowledge. • Ranking of next R&D high priority issues accounting for international research. • Dissemination of knowledge through education courses and ERMSAR conferences. - Abstract: The SARNET network (Severe Accident Research NETwork of excellence), co-funded by the European Commission from 2004 to 2013, has allowed to significantly improve the knowledge on severe accidents and to disseminate it through courses and ERMSAR conferences. The major investigated topics, involving more than 250 researchers from 22 countries, were in- and ex-vessel corium/debris coolability, molten-core–concrete-interaction, steam explosion, hydrogen combustion and mitigation in containment, impact of oxidising conditions on source term, and iodine chemistry. The ranking of the high priority issues was updated to account for the results of recent international research and for the impact of Fukushima nuclear accidents in Japan. In addition, the ASTEC integral code was further developed to capitalize the new knowledge. The network has reached self-sustainability by integration in mid-2013 into the NUGENIA Association. The main activities and outcomes of the network are presented.

    Highlights: • This paper presents a benchmark performed in the frame of the SARNET-2 EU project. • It concerns momentum transfer between a PWR spray and the surrounding gas. • The entrained gas velocities can vary up to 100% from one code to another. • Simplified boundary conditions for sprays are generally used by the code users. • It is shown how these simplified conditions impact the gas entrainment. - Abstract: This paper presents a benchmark performed in the frame of the SARNET-2 EU project, dealing with momentum transfer between a real-scale PWR spray and the surrounding gas. It presents a description of the IRSN tests on the CALIST facility, the participating codes (8 contributions), code-experiment and code-to-code comparisons. It is found that droplet velocities are almost well calculated one meter below the spray nozzle, even if the spread of the spray is not recovered and the values of the entrained gas velocity vary up to 100% from one code to another. Concerning sensitivity analysis, several ‘simplifications’ have been made by the contributors, especially based on the boundary conditions applied at the location where droplets are injected. It is shown here that such simplifications influence droplet and entrained gas characteristics. The next step will be to translate these conclusions in terms of variables representative of interesting parameters for nuclear safety.

  4. SARNET, a success story. Survey of major achievements on severe accidents and of knowledge capitalization within the ASTEC code

    Albiol, T.; Van Dorsselaere, J.P.; Reinke, N.

    2013-01-01

    51 organizations from Europe and Canada cooperated within SARNET (Severe Accident Research Network of Excellence) joining their capacities of research in order to resolve the most important pending issues for enhancing, in regard to Severe Accidents (SA), the safety of existing and future Nuclear Power Plants (NPPs). SARNET defines common research programmes and develops common computer codes and methodologies for safety assessment. The ASTEC integral code, jointly developed by IRSN (France) and GRS (Germany) for Light Water Reactor (LWR) source term SA evaluation, Probabilistic Safety Assessment (PSA) level-2 studies and SA management evaluation, is the main integrating component of SARNET. The scientific knowledge generated in the Corium, Source Term and Containment Topics has been integrated into the code through improved or new physical models. ASTEC constitutes now the reference European SA integral code. During the 4 and half years of SARNET, 30 partners have assessed the successive versions of the ASTEC V1 code through validation. More than 60 scientists have been trained on the code use. Validation tasks on about 65 experiments were performed to cover all physical phenomena occurring in a severe accident: circuit thermalhydraulic, core degradation, fission products (FP) release and transport, Molten-Corium-Concrete-Interaction (MCCI), and in the containment, thermalhydraulic, aerosol and iodine as well as hydrogen behaviour. The overall status of validation can be considered as good, with results often close to results of mechanistic codes. Some reach the limits of present knowledge, for instance on MCCI, and, like in most codes, an adequate model for reflooding of a degraded core is still missing. IRSN and GRS are currently preparing the new series of ASTEC V2 versions that will account for most of the needs of evolution expressed by the SARNET partners. The first version V2.0, planned for March 09, will be applicable to EPR and will include the ICARE2

    The overall aim of the SARNET (Severe Accident Research NETwork), in the EU 6th Framework programme was to integrate in a sustainable manner the research capabilities of fifty-one European organisations from eighteen member states of the European Union (EU) plus the Joint Research Centres, with one Canadian company, to resolve important remaining uncertainties and safety issues concerning existing and future nuclear plant, especially water-cooled reactors, under hypothetical severe accident conditions. It emphasised integrating activities, spreading of excellence (including knowledge transfer) and jointly executed research, with the knowledge gained being encapsulated in the European severe accident modelling code ASTEC. This paper summarises the achievements over the whole project in the Source Term Topic, which dealt with potential radioactive release to the environment, covering release of fission products and structural materials from the core, their transport in the primary circuit, and their behaviour in the containment. The main technical areas covered, as emphasised by the earlier EURSAFE project, were the effect of oxidative conditions on fission product release and transport (especially the behaviour of the highly radiotoxic ruthenium under air ingress conditions), iodine volatility in the primary circuit, control rod aerosol release (Ag-In-Cd) that affects iodine transport, containment by-pass in the case of steam generator tube rupture, aerosol retention in containment cracks, aerosol remobilisation in the circuit, and iodine/ruthenium behaviour in the containment especially concerning the volatile fraction in the atmosphere. The studies also covered performance of new experiments, analysis of existing data, and formulation and improvement of theoretical models. Significant progress was made in each area. Looking to the future, the 7th Framework successor project SARNET2 covers the remaining issues concerning iodine and ruthenium, including practical

  8. Understanding phenomenology.

    Flood, Anne

    2012-01-31

    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.

  11. Exceptional phenomenology

    Aggerholm, Kenneth; Moltke Martiny, Kristian

    Phenomenological research is in traditional terms a matter of going 'back to the things themselves', as Husserl famously stated. But if phenomenology is to renew itself in creative ways and reveal new aspects of human experience it is of value to look for a certain kind of phenomena: exceptions. ...

  12. Phenomenological Lagrangians

    Weinberg, S.

    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.)

  13. Analyses on ex-vessel debris formation and coolability in SARNET frame

    Pohlner, G.; Buck, M.; Meignen, R.; Kudinov, P.; Ma, W.; Polidoro, F.; Takasuo, E.

    2014-01-01

    Highlights: • Melt outflow varies from dripping melt outflow to molten corium jets of variable size. • Experiments show clear trend of producing particles in size range 2-4 mm. • Code calculations show complete solidification of particles, yielding formation of fragmented debris beds. • Limits of debris bed cooling and coolability margins are analysed. - Abstract: The major aim of work in the SARNET2 European project on ex-vessel debris formation and coolability was to get an overall perspective on coolability of melt released from a failed reactor pressure vessel and falling into a water-filled cavity. Especially, accident management concepts for BWRs, dealing with deep water pools below the reactor vessel, are addressed, but also shallower pools in existing PWRs, with questions about partial cooling and time delay of molten corium concrete interaction. The subject can be divided into three main topics: (i) Debris bed formation by breakup of melt, (ii) Coolability of debris and (iii) Coupled treatment of the processes. Accompanied by joint collaborations of the partners, the performed work comprises theoretical, experimental and modelling activities. Theoretical work was done by KTH on the melt outflow conditions from a RPV and on the quantification of the probability of yielding a non-coolable ex-vessel bed by use of probabilistic assessment. IKE introduced a theoretical concept to improve debris bed coolability. A large amount of experimental work was done by partners (KTH, VTT, IKE) on the coolability of debris beds using different bed geometries, particles, heating methods and water feeds, yielding a valuable base for code validation. Modelling work was mainly done by IKE, IRSN, RSE and VTT concerning jet breakup and/or debris bed formation and cooling in 2D and 3D geometries. A benchmark for the DEFOR-A experiment of KTH was performed. Important progress was reached for several tasks and aspects and important insights are given, enabling to focus the

  16. Phenomenology & Sociality

    Gahrn-Andersen, Rasmus; Cowley, Stephen

    2017-01-01

    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....

    2007-01-01

    The PSA2 work package (PSA2 WP) is a part of the Joined Programme Activity of the European Severe Accident Network (SARNET) related to level 2 PSA methodologies. The general objectives of this work package is to provide a comparison of the different methodologies used or under development for level 2 PSA application by the partners involved in the work package and to promote their harmonization. The PSA2 WP is organized into three main topics: methodologies in general, methodologies for uncertainties assessment, and dynamic reliability methods. The different tasks initially defined for these three topics are shortly described and the partners involved identified. Attention is then paid on the methodologies used so far by the different partners to assess the uncertainties in their level 2 PSA. A review of partners approaches to assess - as far as possible - the different sources of possible uncertainties is done for the different following topics: - uncertainties propagated from the level 1 PSA, - uncertainties (in sense of approximation) due to the binning of the level 1 sequences in Plant Damage, - uncertainties related to the structure of the Accident Progression Event Tree, - uncertainties related to the probabilities of stochastic events (system failure or recovery, human actions, some physical phenomena such as ignition of hydrogen combustion or triggering of steam explosion), - uncertainties elated to the modelling of the different physical phenomena, - uncertainties related to the cut-off frequency used in the probabilistic quantification of the Accident Progression Event Tree; - uncertainties related to the binning of level 2 sequences in Release Categories (variables not considered, values of eventual continuous variables). First conclusions of the comparison are given in terms of improvement needs and then of perspectives of the work for the following period of work. (authors)

  20. Synthesis of the ASTEC integral code activities in SARNET – Focus on ASTEC V2 plant applications

    Chatelard, P.; Reinke, N.; Ezzidi, A.; Lombard, V.; Barnak, M.; Lajtha, G.; Slaby, J.; Constantin, M.; Majumdar, P.

    2014-01-01

    Highlights: • Independent assessment of the ASTEC severe accident code vs. experiments is summarised. • Main remaining modelling issues and development perspectives are identified. • Independent assessment of ASTEC code at full scale conditions is described. • Main requirements to address BWR and PHWR types of reactors are identified. - Abstract: Among the 43 organisations which joined the SARNET2 FP7 project from 2009 to 2013, 31 have been involved in the activities on the ASTEC code. This paper presents a synthesis of the main achievements that have been obtained on the ASTEC V2 integral code, jointly developed by IRSN (France) and GRS (Germany), on development, validation vs. experimental data and applications at full scale conditions for both Gen.II and Gen.III plants. As to code development, while the current V2.0 series of ASTEC versions was continuously improved (elaboration and release by IRSN and GRS of three successive V2.0 revisions), IRSN and GRS have also intensively continued in parallel the elaboration of the second ASTEC V2 major version (version V2.1) to be delivered end of 2014. Regarding code validation vs. experiments, the partners have assessed the V2.0 version and subsequent revisions vs. more than 50 experiments; this extended assessment notably confirmed that most models are today close to the State of the Art, while it also corroborated the yet known key-topics on which modelling efforts should focus in priority. As to plant applications, the comparison of ASTEC results with other codes allows concluding on a globally good agreement for in-vessel and ex-vessel severe accident progression. As to ASTEC adaptations to BWR and PHWR, significant achievements have been obtained through the elaboration and integration in the future V2.1 version of dedicated core degradation models, notably to account for multi coolant flows

  2. Phenomenology and homeopathy.

    Whitmarsh, Tom

    2013-07-01

    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.

We illustrate this point through examples from empirical nursing studies, and discuss......Nursing research is often concerned with lived experiences in human life using phenomenological and hermeneutic approaches. These empirical studies may use different creative expressions and art-forms to describe and enhance an embodied and personalised understanding of lived experiences. Drawing...... may support a respectful renewal of phenomenological research traditions in nursing research....

  9. Supersymmetry and Superstring Phenomenology

    Gaillard, Mary K; Gaillard, Mary K.; Zumino, Bruno

    2008-05-05

    We briefly cover the early history of supersymmetry, describe the relation of SUSY quantum field theories to superstring theories and explain why they are considered a likely tool to describe the phenomenology of high energy particle theory beyond the Standard Model.

  10. The Phenomenology of Democracy

    Shaw, Robert

    2009-01-01

    Human beings originate votes, and democracy constitutes decisions. This is the essence of democracy. A phenomenological analysis of the vote and of the decision reveals for us the inherent strength of democracy and its deficiencies. Alexis de Tocqueville pioneered this form of enquiry into democracy and produced positive results from it.…

  11. Superstring inspired phenomenology

    Binetruy, P.

    1988-01-01

    Recent progress in superstring model building is reviewed with an emphasis on the general features of the models obtained. The problems associated with supersymmetry breaking and intermediate gauge symmetry breaking (M W I GUT ) are described. Finally, the phenomenology of these models is summarized, with a discussion of the role that new experimental results could play to help clearing up the above difficulties

    The distribution of transversely polarized quarks inside a transversely polarized nucleon, known as transversity, encodes a basic piece of information on the nucleon structure, sharing the same status with the more familiar unpolarized and helicity distributions. I will review its properties and discuss different ways to access it, with highlights and limitations. Recent phenomenological extractions and perspectives are also presented.

    2009-01-01

    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

  15. Phenomenology in Its Original Sense.

    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.

  16. Resonant diphoton phenomenology simplified

    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.

    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.

  20. Applying the Case Management CourTools: Finding from an Urban Trial Court

    Collins E. Ijoma

    2012-06-01

    Full Text Available The National Center for State Courts (NCSC recently promulgated 10 trial court performance measures, referred to as CourTools. Measures 2, 3, 4, and 5 provide a methodology by which court managers can examine their management and processing of cases. The measures include clearance rate (measure 2, time to disposition (measure 3, age of active pending caseload (measure 4, and trial date certainty (measure 5. The objective of this research was threefold. The first aim was to assess the viability of using the case management measures to examine case processing trends in a New Jersey (NJ urban trial court. Each measure was reviewed to determine the tool’s applicability to the criminal division of the court. The second objective (pursued as a parallel to the first was to present the findings in the same context as the CourTools’ framework to determine its practicality. The final goal was to serve as a platform for other courts on the national and international level that do not yet use performance measures. These courts, diverse as they are, may use the methodologies and findings of this case study as a reference and guide to develop their own program to measure the court’s productivity and efficiency. To that end, this case study sought to answer the following questions in determining the applicability of the CourTools to the selected court and by extension, its potential for more universal application to other court systems. First, what is the relevance of measurements to the courts and why is it important, if at all? Second, what are the CourTools? Third, can the measurement model be applied to an actual court and if so, how is it executed and illustrated in practice? Finally, what are the implications of the findings for the court in question, as well as, other courts that seek to incorporate the CourTools to measure performance?

  1. Highlights on SUSY phenomenology

    Masiero, Antonio

    2004-01-01

    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

  2. Phenomenological consequences of supersymmetry

    Hinchliffe, I.; Littenberg, L.

    1982-01-01

    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

  3. Phenomenology and Mathematics

    Hartimo, Mirja

    2010-01-01

    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.

  5. Neutrinos: Theory and Phenomenology

    Parke, Stephen

    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.

  6. Phenomenology of chromostatics

    Pervushin, V.N.; Kallies, W.; Sarikov, N.A.

    1988-01-01

    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. Scanning the phenomenological MSSM

    A framework to perform scans in the 19-dimensional phenomenological MSSM is developed and used to re-evaluate the ATLAS experiments' sensitivity to R-parity-conserving supersymmetry with LHC Run 2 data ($\\sqrt{s}=13$ TeV), using results from 14 separate ATLAS searches. We perform a $\\tilde{t}_1$ dedicated scan, only considering models with $m_{\\tilde{t}_1}<1$ TeV, while allowing both a neutralino ($\\tilde{\\chi}_1^0$) and a sneutrino ($\\tilde{\

  8. Phenomenological three center model

    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.

  9. Phenomenology and Neuroaesthetics

    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.

    Highlights: • The I{sub 2} transport in two multi-compartment THAI tests was analyzed. • In a benchmark 4 different codes were applied by 7 organizations. • The I{sub 2} concentrations were mostly overestimated, up to a factor 100. • Inadequate iodine models and inaccurate thermal-hydraulic parameters were detected. • The user effect on the quality of the iodine results was large. - Abstract: In the SARNET2 WP8.3 THAI Benchmark the capability of current accident codes to simulate the iodine transport and behavior in sub-divided containments has been assessed. In THAI test Iod-11 and Iod-12, made available for the benchmark, the distribution of molecular iodine (I{sub 2}) in the five compartments of the 60 m{sup 3} vessel under stratified and well mixed conditions was measured. The main processes addressed are the I{sub 2} transport with the atmospheric flows and the interaction of I{sub 2} with the steel surface. During test Iod-11 the surfaces in contact with the containment atmosphere were dry. In Iod-12, steam was released, which condensed on the walls. Nine post-test calculations were conducted for Iod-11 and eight for Iod-12 by seven organizations using four different codes: ASTEC-IODE (CIEMAT, GRS and TUS), COCOSYS-AIM (AREVA, FZ-Jülich and GRS), ECART (Pisa University) and MELCOR (Pisa University and VTT). Different nodalizations of the THAI vessel with 20–65 zones were applied. Generally, for both tests the analytical thermal-hydraulic results are in a fairly good agreement with the measurements. Only the calculated local relative humidity deviates significantly from the measured values in all calculations. The results in Iod-11 for the local I{sub 2} concentration in the gaseous phase are quite diverse. Three calculations show only minor deviations from the measurement, whereas the others are substantially different from the measured I{sub 2} concentrations. For Iod-12, no calculation delivers a satisfactory evolution of the I{sub 2

  15. 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.

  16. 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.

  18. Architecture and Phenomenology: Introduction

    Brendan O’ Byrne

    2014-07-01

    Full Text Available The implications of philosophical aesthetics in the consideration of architecture have been relatively slight. Part of the reason is the neglect of architecture in the work of Baumgarten, Burke and Kant. Within the discourse of architecture the questions raised for philosophical consideration arising out of practice restricted the area of reflection and investigation. The dominant positions were to become either a version of neo-Kantianism, or a direct re-working of Hegel’s Lectures on Aesthetics. The significance of Kant’s distinction between ‘free’ and ‘dependent beauty’ is analysed, and in consequence the need to philosophically question again the relation of architecture to buiding, to dwelling and space. For this the question of accessibility as raised in the phenomenological enquiry, in the work of Brentano, Sartre, Bachelard, Merleau-Ponty, and especially Heidegger points to a different route for the appraisal of philosophical and architectural relations which are exhibited in the contributions of the 10 authors to this issue of Footprint.

  20. [Phenomenology of dreams].

    Pringuey, Dominique

    2011-10-01

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

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

  2. Perspectives on string phenomenology

    Kane, Gordon; Kumar, Piyush

    2015-01-01

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

    2011-08-11

    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.

  5. Phenomenology dependent timescales

    Ouzounian, G.

    2002-01-01

    As required by the French act, Dec. 1991, construction projects for disposing of radioactive wastes have to be submitted to the Parliament by 2006. One of the most important points to allow for a decision at this time will be to gain confidence. The major difficulty in such a technical and societal project is to be able to carry out a demonstration of the safety ver timescales which are out of the scope of any experiment. Among the arguments involved for the safety case are a series of simulations which objective is to assess the level of safety which can be reached, and its robustness to various internal defects (construction of the drifts, welding of canisters...) or external events (intrusion with deep boreholes, climate change, faulting...). Confidence in the simulations can be achieved if they are transparent, based on well understood processes. However, the complexity of the disposal system is such that temptation was great by the past to simplify the models, with a poor level of reporting on justifications, thus leading to what has been described as black-box models. In the frame of the demonstration to be brought out for 2006, ANDRA has developed an approach consisting first to describe and analyse all the processes occurring over time and space in the repository. Once this type of information has been gathered in a structured way, then further analyses leading to abstractions, simplifications can be performed in order to facilitate simulations as required for the safety demonstration. The first stage of the approach has been called the phenomenological analysis of the repository situations PARS). This work gives rise to a reference book in which our knowledge has been reported before being used for the safety demonstration. If also represent a reference for all technical and scientific knowledge based applications, such as digital modeling which is the basis for simulations, the repository design, the reversibility study, including the definition of a

  6. Réception des cours magistraux avec support projeté en contexte universitaire

    Dufour Sophie

    2012-07-01

    Full Text Available Les cours magistraux sont mixtes, utilisant à la fois l’oral et l’écrit. Comme dans d’autres formes d’enseignement universitaire, de nouveaux écrits y prennent une place de plus en plus importante. Ce sont des genres écrits spécifiques générés en particulier par les Tice et les logiciels de type PowerPoint. Ces supports ont une influence sur l’activité des étudiants exposés à ce double flux d’informations écrites et orales. Il s’agit d’une part de mieux observer le fonctionnement dynamique de ces combinaisons synchrones oralographiques, et, d’autre part, d’en observer les conséquences sur le travail de réception et de stabilisation, par les étudiants. Nous nous inscrivons ici dans la lignée des travaux menés depuis plusieurs années au sein de notre laboratoire sur l’analyse des cours magistraux, qui ont mis en évidence un certain nombre de phénomènes discursifs et contextuels susceptibles d’avoir un impact sur leur réception par les étudiants. L'enquête réalisée en entretiens semis-guidés auprès d’étudiants de cursus divers qui a fourni les données à la base du travail que nous proposons, permettra dans un premier temps d'approcher les comportements de réception des étudiants en CM. Nous aborderons ensuite la complémentarité discursive existant entre le discours oral de l’enseignant en CM et l’écrit public qu’il projette à son auditoire sous forme de PPT. Enfin nous évaluerons l’intérêt que les étudiants peuvent entrevoir dans la mise à disposition via des plateformes de cours de type BV soit avant, soit après le cours du PPT proposé par l’enseignant.

  11. A Phenomenology of Expert Musicianship

    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...

    In the fleet of European nuclear power plants, with a very low probability circumstances, severe accident sequences may result in core melting and plant damage leading to dispersal of radioactive material into the environment and thus constituting a health hazard to the public well beyond the borders of the State where the damaged plant is located. It is therefore crucial that the best state of knowledge on severe accident phenomenology, qualified computer tools and appropriate methodology should be used uniformly throughout Europe, in order to evaluate the corresponding risks and update former evaluations, taking into account notably the inevitable evolutions in reactor operations.

  6. [Social actors and phenomenologic modelling].

    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.

  7. Phenomenological aspects of mirage mediation

    Loewen, Valeri

    2009-07-15

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

  9. Phenomenology of unified gauge theories

    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)

  10. Phenomenology and hermeneutics - poles apart?

    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.

    Ali, A.

    1981-09-01

    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.)

  12. Phenomenology of stochastic exponential growth

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

    2017-06-01

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

  13. Phenomenology and theory of confinement

    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

  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.

  15. The POSNA-COUR International Scholar Program. Results of the First 7 Years.

    Fornari, Eric D; Sabharwal, Sanjeev; Schwend, Richard M

    2017-12-01

    The Pediatric Orthopedic Society of North America (POSNA)-Children's Orthopedics in Underserved Regions (COUR) International Scholar Program was initiated in 2007 to provide educational opportunities for emerging leaders who treat children with orthopaedic conditions in resource-challenged environments worldwide. Financial support is available each year for 4 to 6 orthopaedic surgeons to attend either the POSNA Annual Meeting or the International Pediatric Orthopedic Symposium. The scholars are also encouraged to visit selected centers for observerships during their trip. Since 2007 there have been 41 international scholars who have participated in the program. We wished to assess the impact of the program and to obtain feedback to improve the experience for future participants. A 23-question web-based survey was created and sent to 38 past scholars from 22 countries who have participated in the program by July 2013. The responses were gathered online and the data were analyzed for the 24 (62%) respondents from 18 countries who completed the survey. Of the respondents, 16/24 (66%) reported that their current practice is comprised of at least 75% pediatrics. Twelve of 24 (52%) were fellowship trained in pediatric orthopaedics, typically outside of North America. All scholars found the meeting they attended to be very useful and have subsequently made changes to their clinical practice. Nineteen of 24 (82%) did a premeeting or postmeeting observership. Twenty-two of 24 (92%) participants have remained in contact with POSNA members they met at the meeting, with 86% of respondents stating that they have subsequently consulted POSNA members on management of patients. Sixty-two percent of the scholars had a POSNA member visit them following the scholarship and 29% have since returned to visit POSNA members for further clinical observerships. Twenty-one of 24 (91%) have had the opportunity to share the knowledge they gained with others in their region through lectures

  16. Embodiment and psychopathology: a phenomenological perspective.

    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.

  17. Recent Trends in Superstring Phenomenology

    Bianchi, Massimo

    2009-01-01

    We review for non-experts possible phenomenological scenari in String Theory. In particular we focus on vacuum configurations with intersecting and/or magnetized unoriented D-branes. 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.

  18. Phenomenology of neutral current interactions

    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

  20. A phenomenological calculus of Wiener description space.

    Richardson, I W; Louie, A H

    2007-10-01

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

  1. Bien faire un cours, un exposé, une conférence

    Brown, George

    1981-01-01

    Le livre de Georges Brown est un livre important pour deux raisons : - Parce qu'il propose à tous les formateurs et enseignants une approche méthodologique de la transmission orale des connaissances. En effet, il ne suffit pas de bien connaître son sujet pour le faire comprendre à son auditoire. Ce livre est conçu pour mener le lecteur pas à pas dans la découverte de son propre style d'explication, de ses points faibles et de ses points forts. - Parce qu'il permet au lecteur, grâce à la pratique des 45 exercices contenus dans l'ouvrage, de faire alterner la réflexion et la performance individuelle avec l'échange d'expériences et l'auto-évaluation des méthodes d'enseignement oral. Ce livre, qui possède toutes les qualités du pragmatisme anglo-saxon, met au service de la formation un outil essentiellement pratique. Il s'adresse donc à tous ceux qui donnent des cours, font des séminaires,ou ont à exposer leurs idées devant un auditoire. EXPLIQUER, C'EST D'ABORD SAVOIR COMMUNIQUER.

  2. Introduction à la thermodynamique cours et problèmes résolus

    Lhuillier, Claire

    1994-01-01

    Si la thermodynamique fait appel à des concepts comme l'entropie, son étude renvoie souvent à des phénomènes courants (les changements d'état) ou encore à des technologies lourdes (les centrales thermiques). De ce fait, on la considère parfois comme une discipline difficile d'accès. Dans le cadre de leur enseignement de première année de premier cycle, Claire LHUILLIER et Jean ROUS ont rédigé un cours - appuyé de très nombreux exemples - dans lesquels ils introduisent avec clarté et rigueur toutes les notions de base : pression, température, énergie interne, premier principe, travail des forces de pression, chaleurs, etc. L'introduction de l'entropie est dissociée de celle du second principe : c'est une fonction d'état qui mesure l'information microscopique manquante. Le second principe est alors formulé comme un principe d'évolution, adapté à l'étude des phénomènes irréversibles. Les potentiels thermodynamiques ont été plus longuement traités dans cette nouvelle édition. Une f...

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

    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.

  8. Phenomenology between Pathos and Response

    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.  

  9. Phenomenological aspects of unified theories

    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

  12. Phenomenology of large Nc QCD

    Lebed, R.F.

    1999-01-01

    These lectures are designed to introduce the methods and results of large N c QCD in a presentation intended for nuclear and particle physicists alike. Beginning with definitions and motivations of the approach, we demonstrate that all quark and gluon Feynman diagrams are organized into classes based on powers of 1/N c . We then show that this result can be translated into definite statements about mesons and baryons containing arbitrary numbers of constituents. In the mesons, numerous well-known phenomenological properties follow as immediate consequences of simply counting powers of N c , while for the baryons, quantitative large N c analyses of masses and other properties are seen to agree with experiment, even when 'large' N c is set equal to its observed value of 3. Large N c reasoning is also used to explain some simple features of nuclear interactions. (author)

  14. Observation and phenomenology of glueballs

    Lindenbaum, S.J.

    1985-01-01

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

  15. Strong moduli stabilization and phenomenology

    Dudas, Emilian; Mambrini, Yann; Mustafayev, Azar; Olive, Keith A

    2013-01-01

    We describe the resulting phenomenology of string theory/supergravity models with strong moduli stabilization. The KL model with F-term uplifting, is one such example. Models of this type predict universal scalar masses equal to the gravitino mass. In contrast, A-terms receive highly suppressed gravity mediated contributions. Under certain conditions, the same conclusion is valid for gaugino masses, which like A-terms, are then determined by anomalies. In such models, we are forced to relatively large gravitino masses (30-1000 TeV). We compute the low energy spectrum as a function of m_{3/2}. We see that the Higgs masses naturally takes values between 125-130 GeV. The lower limit is obtained from the requirement of chargino masses greater than 104 GeV, while the upper limit is determined by the relic density of dark matter (wino-like).

  16. Phenomenological studies of hadronic collisions

    van Zijl, M.

    1987-04-01

    Several aspects of hadronic collisions are studied in a phenomenological framework. A Monte Carlo model for initial state parton showers, using a backwards evolution scheme, is presented. Comparisons with experimental data and analytical calculations are made. The consequence of using different fragmentation model on the determination of α s is also investigated. It is found that the different fragmentation models lead to the reconstruction of significantly α s values. Finally the possibility of having several independent parton-parton interactions in a hadron-hadron collision is studied. A model is developed, which takes into account the effects of variable impact parameters. This is implemented in a Monte Carlo computer program and extensive comparisons with experimental data are carried out. There is clear evidence in favour of multiple interactions with variable impact parameters. (author)

  17. Astroparticle physics theory and phenomenology

    Sigl, Günter

    2017-01-01

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

  18. Quantum groups in hadron phenomenology

    Gavrilik, A.M.

    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

The second question which arises is „How to pursue moral phenomenology”? The third question is „Why pursue moral phenomenology”? We will analyze the study Moral phenomenology:foundation issues1, by which the American phenomenologist Uriah Kriegel aims three lines of research: the definition of moral phenomenology and the description of field research within the phenomenological tradition; the establishment of a method of moral phenomenology research; the emphasis of the purpose of such research and its importance for moral philosophy in general.

  1. SLED phenomenology: curvature vs. volume

    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.

    Highlights: → The SARNET network gathers most worldwide actors involved in severe accident research. → It defines common research programmes for resolving the most important pending safety issues. → It optimises the use of the available European resources and constitutes sustainable research groups. → It disseminates the knowledge on severe accidents through education courses. → Knowledge produced is capitalized through physical models in the ASTEC simulation code. - Abstract: In order to optimise the use of the available means and to constitute sustainable research groups in the European Union, the Severe Accident Research NETwork of Excellence (SARNET) has gathered, between 2004 and 2008, 51 organizations representing most of the actors involved in severe accident (SA) research in Europe plus Canada. This project was co-funded by the European Commission (EC) under the 6th Euratom Framework Programme. Its objective was to resolve the most important pending issues for enhancing, in regard of SA, the safety of existing and future nuclear power plants (NPPs). SARNET tackled the fragmentation that existed between the national R and D programmes, in defining common research programmes and developing common computer codes and methodologies for safety assessment. The Joint Programme of Activities consisted in: -Implementing an advanced communication tool for accessing all project information, fostering exchange of information, and managing documents; - Harmonizing and re-orienting the research programmes, and defining new ones; -Analyzing the experimental results provided by research programmes in order to elaborate a common understanding of relevant phenomena; -Developing the ASTEC code (integral computer code used to predict the NPP behaviour during a postulated SA) by capitalizing in terms of physical models the knowledge produced within SARNET; - Developing scientific databases, in which the results of research experimental programmes are stored in a common

  3. Low-energy phenomenological chiral Lagrangians

    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

  5. Heavy quark and sparticle phenomenology

    Barger, V.

    1985-01-01

    Data from the CERN p anti p collider provide a new avenue for the study of heavy-quark production and possibly also provide the first indication for the sparticles of supersymmetry. This discussion of the associated phenomenology begins with charm and bottom quarks, proceeds to the strategies that lead to top quark identification, and concludes with possible supersymmetry scenarios to explain the events observed by the UA1 collaboration with large missing transverse momentum. The fusion predictions of single muon and dimuon rates are in the ballpark of UA1 observations. The discovery of isolated like-sign dimuons is at present an anomaly. The p anti p collider is a good place to do B physics, and answer the question of whether B 0 - anti B 0 mixing occurs. Also, it should soon be possible to identify a few dimuon events of W → t anti b and t anti t origins. Finally, enhanced charm in jets, if established, would have to be ascribed to non-perturbative QCD effects. In conclusion, if the UA1 monojets are of supersymmetry origin, then squark and gluino masses are already tightly constrained and dijet events with large missing transverse momentum should help distinguish between the two most promising scenarios. The top signal is not being faked by sparticles. (Nogami, K.)

  6. Phenomenology of the CAH+ measure

    Salem, Michael P.; Vilenkin, Alexander

    2011-01-01

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

  7. Phenomenology of ELDER dark matter

    Kuflik, Eric; Perelstein, Maxim; Lorier, Nicolas Rey-Le; Tsai, Yu-Dai

    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.

    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.

  15. Ethics in Husserl’s Phenomenology

    Hasan FathZadeh

    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.

    Donnachie, A.

    1994-01-01

    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

  20. Being Mindful as a Phenomenological Attitude.

    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.

  1. Phenomenology and its application in medicine.

    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.

  2. Phenomenology of modern education quality

    Natalya G. Kulikova

    2017-01-01

    Full Text Available The national priority question of education quality is considered in the article at the level of an in-depth – existential – function of the educational system, where the former arises. In that case, education appears not only as a social organism, but a fundamental form of understanding existence and self-realization of a person as a self-organized space and biosocial system in terms of an integral educational result. The mechanisms and effects of formal development logic become clear from such research perspective namely, that changes into philosophy of education in the shape of a single-dimensional methodological imperative and provides for an inconsistency of educational practice, achievement of some pedagogical aims at the expense and to the disadvantage of others. The limited nature of pedagogical thinking is not simply fixed in the paradoxes of human development as an individual and organism, but is considered as the main obstacle in the way of evolution of the Human-Nature-Society global system. The phenomenological comprehension of education problems supposes coming into the space of a spiritual idea, funding the process of searching for quality at different levels of human life and activities from within, which characterizes the topicality of the given article. The aim of the scientific research is to analyze factors limiting the process of modern human development, and to ground the necessity of the fundamental updating of the education model in the noospheric scientific paradigm. Theoretical methods of research are used in the paper: analysis of scientific literature, system analysis, analogy, systematization, and generalization. The research results are represented in the categories of education philosophy and focus the reader’s attention mainly on its critical-reflexive function. Elimination of the subject of education is considered as a logical result of phenomenological reduction of thinking that loses a higher level of

  3. Conducting phenomenological research: Rationalizing the methods and rigour of the phenomenology of practice.

    2018-03-15

    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.

  4. Phenomenological aspects of the cognitive rumination construct

    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.

  6. 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.

  7. Heidegger’s phenomenology of the invisible

    Andrzej SERAFIN

    2016-12-01

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

  8. Neutron relativistic phenomenological and microscopic optical potential

    Shen Qing-biao; Feng Da-chun; Zhuo Yi-zhong

    1991-01-01

    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

  9. Introduction de compétences managériales dans les cours et tribunaux belges

    2010-02-01

    Full Text Available Depuis quelques années et jusqu’à ce jour, les Cours et tribunaux belges sont le théâtre d’un vaste processus de « modernisation ». Depuis l’affaire Dutroux – qui a révélé les dysfonctionnements de la Justice et de la police belge –, on ne compte plus les initiatives visant à améliorer la « qualité » de l’appareil judiciaire. Pour mener à bien cet objectif, des dispositifs de différentes natures ont été développés. Dans le cadre de cette contribution, nous proposons d’étudier l’un d’entre eux : l’introduction de conseillers en gestion des ressources humaines dans certaines juridictions du pays. En nous inscrivant dans la lignée des travaux de sociologie des organisations, nous posons l’hypothèse que l’apparition d’un nouvel acteur devrait mener à une réévaluation des rôles, des stratégies et des comportements du système d’action local. Cependant, à l’issue de nos observations, l’impact du dispositif apparait faible. Ce qui nous mène à redéfinir notre hypothèse et à envisager ces conseillers comme des « opérateurs cognitifs » du changement. En envisageant l’action de ces conseillers comme le résultat d’un processus, il a été possible de mettre au jour les idéologies dont ce dispositif est porteur, ainsi que l’émergence de représentations collectives susceptibles de fournir un nouveau référent commun, un nouvel « éthos professionnel ».The introduction of "human resources advisers" in several courts’ staff in BelgiumA large-scale process of "modernization" has taken place in Belgian courts in the past few years.

    . The phenomenological methodology according to Spiegelberg is described, and exemplified through the author's ongoing study. Different critiques of phenomenology and phenomenological reports are mentioned, and the phenomenological description is illustrated as the metaphor «using a handful of colors». The metaphor...... is used to give phenomenological researchers and readers an expanding reality picturing, including memories and hopes and not only a reality of the five senses. It is concluded that phenomenology as a world view and methodology can contribute to nursing research and strengthen the identity of nursing...

  11. Towards a Relational Phenomenology of Violence.

    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.

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

    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.

    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.)

  15. Phenomenological realism, superconductivity and quantum mechanics

    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

    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

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

    Earle, Vicki

    2010-10-01

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

  7. Dreaming Consciousness: A Contribution from Phenomenology

    Nicola Zippel

    2016-08-01

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

  20. 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.

  3. A phenomenological attempt at understanding otherness

    A. KOVÁCS

    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.

  4. Generalized uncertainty principle and quantum gravity phenomenology

    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.

  5. Phenomenological two-nucleon interaction operator

    1981-01-01

    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.)

  7. [How to think a phenomenological clinic].

    Rovaletti, María L

    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.

    2014-12-01

    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.

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

    Standal, Øyvind F

    2014-01-01

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

    Oksengendler, B.L.; Turaeva, N.N.; Azimov, J.; Rashidova, S.Sh.

    2010-01-01

    The phenomenological model of matrix nanoclusters is presented based on the Wood-Saxon potential used in nuclear physics. In frame of this model the following problems have been considered: calculation of width of diffusive layer between nanocluster and matrix, definition of Tamm surface electronic state taking into account the diffusive layer width, receiving the expression for specific magnetic moment of nanoclusters taking into account the interface width.

    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...

  12. Why natural science needs phenomenological philosophy.

    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).

  15. Phenomenology of BWR fuel assembly degradation

    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.

    2017-03-01

    Full Text Available En vertu de l'article 3 de la Convention européenne de sauvegarde des droits de l'homme, les Etats ne peuvent ni pratiquer la torture ni infliger des traitements inhumains ou dégradants. Le particularisme de cette convention par rapport aux autres textes internationaux ou régionaux relatifs aux droits de l’homme réside indéniablement dans le système de protection existant qu’elle a organisé. Un organe juridictionnel, la cour européenne des droits de l’homme, est en charge de sanctionner les Etats qui ne respectent la Convention. Au terme d’une jurisprudence novatrice et évolutive, la cour européenne des droits de l’homme impose de plus en plus efficacement de lutter contre la torture, les traitements inhumains et dégradants.

De plus, l’alcool au volant représente, après la vitesse excessive, la deuxième cause d’accidents mortels sur la route. Quoique autorisé au volant à faibles doses dans certains pays, l’alcool met toujours en danger la vie du chauffeur et de ses passagers. Le taux d’alcool dans le sang, pour la même quantité d’éthanol consommée, varie en fonction de différents facteurs physiologiques. Il existe à l’heure actuelle de nombreuses modalités d’estimer l’évolution de l’alcoolémie au cours du temps. Nous avons essayé de démontrer que cette évolution présente une forte variabilité, en fonction du sexe, de l’age et de la physiologie individuelle

  19. Energy transition: future of the planet or expensive utopia? The truths of the Cour des Comptes report of 2013

    Giansily, Jean-Antoine

    2013-01-01

    While providing in appendix an article published by four politicians concerned by the evolution of the relationship between the French society and sciences and techniques, an article on the difficult situation of a Danish leader company of the wind energy sector (Vestas), and the general conclusions of a report by the French Cour des Comptes (Court of Audit) on the French policy of development of renewable energies, the author first highlight some elements published in this last report regarding energy consumption sources, CO 2 emissions, electricity prices for households and for industries in France and in other European countries, and French and European objectives of renewable energy production. The author more particularly discusses these last objectives which he considers as being unrealistic and expensive, notably because of a lack of economic growth which may last long. He therefore considers nuclear energy as a good solution as it does not emit any CO 2 , and is far less expensive than renewable energies which he calls random energies

  20. Estimation de la survie des alevins de carpe (C. carpio au cours de leur premier mois d'existence

    MOREAU J.

    1979-10-01

    Full Text Available Des observations réalisées sur deux stations piscicoles de Madagascar, dans des étangs ne recevant ni engrais ni nourriture, révèlent qu'au cours de leur premier mois les alevins de carpe (C. carpio subissent des mortalités voi-sines de 50 %. Ces dernières sont encore plus élevées en début et en fin de saison de reproduction. Au début, les fortes mortalités sont dues à la température trop basse et aux disponibilités alimentaires insuffisantes ; en fin de saison de reproduction, la température trop élevée et la mauvaise qualité des œufs sont sans doute en cause. Une fumure adéquate des étangs de grossissement des alevins et une alimentation correcte des géniteurs permettront peut-être de diminuer ces mortalités.

  2. Evolution de films de cuivre sur un substrat de cordiérite au cours de traitements thermiques

    Guille, Jean-Louis; Gondolf, Marc

    1993-04-01

    Copper films were applied on low sintering temperature cordierite substrates either by sputtering or screen printing. Their behaviour during thermal treatments was studied as a function of various parameters : deposition technique, thickness, firing atmosphere, physical state of the substrate (green or sintered). Films were most often broken during the treatment. In the case of screen printed films the effects of an oxydation-reduction cycle of copper are pointed out. Des films de cuivre ont été déposés sur un substrat de cordiérite à basse température de frittage par deux techniques, pulvérisation cathodique et sérigraphie. On étudie leur comportement au cours de traitements thermiques en fonction de différents paramètres : technique de déposition, épaisseur, atmosphère de traitement, état physique du substrat (cru ou fritté). On constate le plus souvent une fragmentation du film. Dans le cas des films sérigraphiés on met en évidence les effets dus à l'oxydation et à la réduction du cuivre.

  3. Anaerobic p-coumarate degradation by Rhodopseudomonas palustris and identification of CouR, a MarR repressor protein that binds p-coumaroyl coenzyme A.

    Hirakawa, Hidetada; Schaefer, Amy L; Greenberg, E Peter; Harwood, Caroline S

    2012-04-01

    The phenylpropanoid p-coumarate and structurally related aromatic compounds are produced in large amounts by green plants and are excellent carbon sources for many soil bacteria. Aerobic bacteria remove the acyl side chain from phenylpropanoids to leave an aromatic aldehyde, which then enters one of several possible central pathways of benzene ring degradation. We investigated the pathway for the anaerobic degradation of p-coumarate by the phototrophic bacterium Rhodopseudomonas palustris and found that it also follows this metabolic logic. We characterized enzymes for the conversion of p-coumarate to p-hydroxybenzaldehyde and acetyl coenzyme A (acetyl-CoA) encoded by the couAB operon. We also identified a MarR family transcriptional regulator that we named CouR. A couR mutant had elevated couAB expression. In addition, His-tagged CouR bound with high affinity to a DNA fragment encompassing the couAB promoter region, and binding was abrogated by the addition of nanomolar quantities of p-coumaroyl-CoA but not by p-coumarate. Footprinting demonstrated binding of CouR to an inverted repeat sequence that overlaps the -10 region of the couAB promoter. Our results provide evidence for binding of a CoA-modified aromatic compound by a MarR family member. Although the MarR family is widely distributed in bacteria and archaea and includes over 12,000 members, ligands have been identified for relatively few family members. Here we provide biochemical evidence for a new category of MarR ligand.

    2016-04-01

    Full Text Available Backchannel technology can be used to allow students in large lecture courses to communicate with each other and the instructor during the delivery of lecture content and class discussions. It can also be utilized by instructors to capture, summarize, and integrate student questions, ideas, and needs into course content both immediately and throughout the course. The authors integrated backchannel software in one of two sections of a course, leaving the other section as a control; combined, the two sections contained a total number of 871 students. Data was gathered comparing both groups using online surveys and semester grades; results showed that the section using backchannel software had higher class satisfaction and perception of engagement, used their mobile devices more for accessing class content, felt more comfortable participating in class discussions, and had a higher grade average than the section that did not. The authors also explore their own experiences of finding, integrating, and maintaining backchannel technology. La technologie d’arrière-plan peut permettre aux étudiants de grands cours magistraux de communiquer les uns avec les autres et avec l’instructeur durant le cours et les discussions en classe. Les instructeurs peuvent aussi l’utiliser pour saisir, résumer et intégrer les questions, idées et besoins des étudiants dans le contenu du cours, et ce, immédiatement et pendant toute la durée du cours. Les auteurs ont intégré un logiciel d’arrière-plan dans l’une des deux sections d’un cours, faisant de l’autre section son groupe témoin. Ensemble, les deux sections comprenaient 871 étudiants. Des données ont été recueillies pour comparer les deux groupes à l’aide de sondages en ligne et des notes du trimestre. Les résultats ont démontré que la section utilisant le logiciel d’arrière-plan avait une plus grande satisfaction et une meilleure perception de l’engagement, que ses

  5. Making humor together: phenomenology and interracial humor

    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

  6. Phenomenology of heavy quarkonia and quantum chromodynamics

    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

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

    Moustafa, Ahmed A; El Haj, Mohamad

    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.

  8. Phenomenology of chiral damping in noncentrosymmetric magnets

    Akosa, Collins Ashu; Miron, Ioan Mihai; Gaudin, Gilles; Manchon, Aurelien

    2016-01-01

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

    1997-12-01

    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

  11. The phenomenology of scalar colour octets

    Krasnikov, N.V.

    1995-01-01

    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

  12. Quantum supergravity, supergravity anomalies and string phenomenology

    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.

  13. Phenomenology and treatment of behavioural addictions.

    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.

    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

  16. Subjectivity and intersubjectivity between semiotics and phenomenology

    Francesco Marsciani

    2014-12-01

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

  17. Melanie Klein's metapsychology: phenomenological and mechanistic perspective.

    Mackay, N

    1981-01-01

    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".

    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...

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

  4. Beyond Empathy. Phenomenological Approaches to Intersubjectivity

    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. 

  5. Phenomenological applications of perturbative quantum chromodynamics

    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

  6. 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.

  7. Destruction as a Step in Heidegger's Phenomenology

    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.

  8. Husserlian Phenomenology as a Kind of Introspection

    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.

  9. Particle Phenomenology of Compact Extra Dimensions

    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

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

    Matua, Gerald Amandu

    2015-03-01

    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.

  11. Merleau-Ponty's Phenomenology of Language and General Semantics.

    Lapointe, Francois H.

    A survey of Maurice Merleau-Ponty's views on the phenomenology of language yields insight into the basic semiotic nature of language. Merleau-ponty's conceptions stand in opposition to Saussure's linguistic postulations and Korzybski's scientism. That is, if language is studied phenomenologically, the acts of speech and gesture take on greater…

    2013-02-01

    Full Text Available Educational Technology and Design 879 is a graduate course that introduces students to the basics of video design and production. In an attempt to improve the learning experience for students a redesign of the course was implemented for the summer of 2011 that incorporated an authentic design studio model. The design studio approach is based on the idea of working and learning in a shared space. Offering a course that employs a studio design model provides the opportunity for exchanging ideas, sharing artifacts, and developing community more deeply and more quickly. What makes this course offering different is the combination of authentic tasks incorporating both online and face-to-face design studio environments. This paper will describe how a studio design approach combined with an authentic learning design was implemented and what was learned. Educational Technology and Design 879 est un cours d'études supérieures initiant les étudiants aux rudiments de la conception et de la production vidéo. Pour améliorer l’expérience d'apprentissage, une refonte du cours a été entreprise à l'été 2011 en intégrant un authentique modèle de studio de design. L'approche « studio de design » repose sur l'idée d’un travail et d'un apprentissage réalisés dans un espace partagé. Un cours utilisant un modèle de studio de design offre la possibilité d'échanger des idées, de partager des artefacts et de développer une communauté plus en profondeur et plus rapidement. Ce qui rend ce cours unique est la combinaison de tâches authentiques qui incorporent des environnements de studio de design à la fois en ligne et en face à face. Cet article décrit comment une approche « studio de design » combinée à une conception d'apprentissage authentique a été mise en œuvre et ce qu’on en a appris.

  1. Δ(54) flavor phenomenology and strings

    Δ(54) can serve as a flavor symmetry in particle physics, but remains almost unexplored. We show that in a classification of semi-realistic ℤ{sub 3}×ℤ{sub 3} heterotic string orbifolds, Δ(54) turns out to be the most natural flavor symmetry, providing additional motivation for its study. We revisit its phenomenological potential from a low-energy perspective and subject to the constraints of string models. We find a model with Δ(54) arising from heterotic orbifolds that leads to the Gatto-Sartori-Tonin relation for quarks and charged-leptons. Additionally, in the neutrino sector, it leads to a normal hierarchy for neutrino masses and a correlation between the reactor and the atmospheric mixing angles, the latter taking values in the second octant and being compatible at three sigmas with experimental data.

  2. Yukawa Bound States and Their LHC Phenomenology

    Enkhbat Tsedenbaljir

    2013-01-01

    Full Text Available We present the current status on the possible bound states of extra generation quarks. These include phenomenology and search strategy at the LHC. If chiral fourth-generation quarks do exist their strong Yukawa couplings, implied by current experimental lower bound on their masses, may lead to formation of bound states. Due to nearly degenerate 4G masses suggested by Precision Electroweak Test one can employ “heavy isospin” symmetry to classify possible spectrum. Among these states, the color-octet isosinglet vector ω 8 is the easiest to be produced at the LHC. The discovery potential and corresponding decay channels are covered in this paper. With possible light Higgs at ~125 GeV two-Higgs doublet version is briefly discussed.

  3. Intuition in emergency nursing: a phenomenological study.

    Lyneham, Joy; Parkinson, Camillus; Denholm, Carey

    2008-04-01

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

  4. On the geometric phenomenology of static friction.

    Ghosh, Shankar; Merin, A P; Nitsure, Nitin

    2017-09-06

    In this note we introduce a hierarchy of phase spaces for static friction, which give a graphical way to systematically quantify the directional dependence in static friction via subregions of the phase spaces. We experimentally plot these subregions to obtain phenomenological descriptions for static friction in various examples where the macroscopic shape of the object affects the frictional response. The phase spaces have the universal property that for any experiment in which a given object is put on a substrate fashioned from a chosen material with a specified nature of contact, the frictional behaviour can be read off from a uniquely determined classifying map on the control space of the experiment which takes values in the appropriate phase space.

  5. Phenomenological theory of superfluidity and superconductivity

    Rabinowitz, M.

    1994-01-01

    Quantum condensation is used here as the basis for a phenomenological theory of superfluidity and superconductivity. It leads to remarkably good calculations of the transition temperatures T c of superfluid 3 He and 4 He, as well as a large number of cuprate, heavy fermion, organic, dichalcogenide, and bismuth oxide superconductors. Although this approach may apply least to the long-coherence-length metallics, reasonably good estimates are made for them and chevral superconductors. T c for atomic H is estimated. T c can be calculated as a function of number density or density of states and effective mass of normal carriers; or alternatively with the Fermi energy as the only input parameter. Predictions are made for a total of 26 superconductors and four superfluids. An estimate is also made for coherence lengths

  6. Phenomenological approaches of dissipative heavy ion collisions

    Ngo, C.

    1983-09-01

    These lectures describe the properties of dissipative heavy ion collisions observed in low bombarding energy heavy ion reactions. These dissipative collisions are of two different types: fusion and deep inelastic reactions. Their main experimental properties are described on selected examples. It is shown how it is possible to give a simple interpretation to the data. A large number of phenomenological models have been developped to understand dissipative heavy ion collisions. The most important are those describing the collision by classical mechanics and friction forces, the diffusion models, and transport theories which merge both preceding approaches. A special emphasis has been done on two phenomena observed in dissipative heavy ion collisions: charge equilibratium for which we can show the existence of quantum fluctuations, and fast fission which appears as an intermediate mechanism between deep inelastic reactions and compound nucleus formation [fr

  7. Palatini actions and quantum gravity phenomenology

    Olmo, Gonzalo J.

    2011-01-01

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

  9. The Phenomenology of Small-Scale Turbulence

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

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

  10. The phenomenology in the environmental aesthetic education

    Noguera de Echeverri, Ana Patricia

    2000-01-01

    In this paper we present an abstract about our Philosophical Doctor Thesis make on Campinas University (Sao Paulo, Brazil) titled educacion estetico ambiental y fenomenologia: problemas de la educacion estetico ambiental en la modernidad. In this thesis we do a critical thinking about the epistemological model of relation subject -object on modern education, and on the other side, we work in the construction about a aesthetic - environmental education model. We propose here an aesthetization of the education, for conjoint body and world-of-life (lebenswelt) into scenarios and actors of the pedagogical process. Body and world-of-life, are two concepts of Husserl's phenomenology that open the door about the environment' s studies aesthetization and aesthetic' s studies environment, separated on modernity, between the metaphysical subject and physicality objects. Body and world-of-life -symbolic-biotic- are marginal alterities on modernity. This marginality has been a structural lead on the contemporary environmental problems

  11. Phenomenological evidence for two types of paranoia.

    Chadwick, P D J; Trower, P; Juusti-Butler, T-M; Maguire, N

    2005-01-01

    Two types of paranoia have been identified, namely persecution (or 'Poor Me') paranoia, and punishment (or 'Bad Me') paranoia. This research tests predicted differences in phenomenology--specifically, in person evaluative beliefs, self-esteem, depression, anxiety, and anger. Fifty-three people with current paranoid beliefs were classified as Poor Me, Bad Me, or neither (classification was reliable). Key dependent variables were measured. All predictions were supported, except the one relating to anger, where the two groups did not differ. The Bad Me group had lower self-esteem, more negative self-evaluative thinking, lower negative evaluations about others, higher depression and anxiety. Importantly, the differences in self-esteem and self-evaluations were not fully accounted for by differences in depression. Data support the presence of two distinct topographies of paranoia. Future research is needed to explore the theory further and examine clinical implications. Copyright 2005 S. Karger AG, Basel

  12. Phenomenological BRDF modeling for engineering applications

    Jafolla, James C.; Stokes, Jeffrey A.; Sullivan, Robert J.

    1997-09-01

    The application of analytical light scattering techniques for virtual prototyping the optical performance of paint coatings provides an effective tool for optimizing paint design for specific optical requirements. This paper describes the phenomenological basis for the scattering coatings computer aided design (ScatCad) code. The ScatCad code predicts the bidirectional reflectance distribution function (BRDF) and the hemispherical directional reflectance (HDR) of pigmented paint coatings for the purpose of coating design optimization. The code uses techniques for computing the pigment single scattering phase function, multiple scattering radiative transfer, and rough surface scattering to calculate the BRDF and HDR based on the fundamental optical properties of the pigment(s) and binder, pigment number density and size distribution, and surface roughness of the binder-interface and substrate. This is a significant enhancement to the two- flux, Kubelka-Munk analysis that has traditionally been used in the coatings industry. Example calculations and comparison with measurements are also presented.

  13. General phenomenology of underground nuclear explosions

    Derlich, S.; Supiot, F.

    1969-01-01

    An essentially qualitatively description is given of the phenomena related to underground nuclear explosions (explosion of a single unit, of several units in line, and simultaneous explosions). In the first chapter are described the phenomena which are common to contained explosions and to explosions forming craters (formation and propagation of a shock-wave causing the vaporization, the fusion and the fracturing of the medium). The second chapter describes the phenomena related to contained explosions (formation of a cavity with a chimney). The third chapter is devoted to the phenomenology of test explosions which form a crater; it describes in particular the mechanism of formation and the different types of craters as a function of the depth of the explosion and of the nature of the ground. The aerial phenomena connected with explosions which form a crater: shock wave in the air and focussing at a large distance, and dust clouds, are also dealt with. (authors) [fr

  14. Phenomenology of induced electroweak symmetry breaking

    Chang, Spencer; Galloway, Jamison; Luty, Markus A.; Salvioni, Ennio; Tsai, Yuhsin

    2015-01-01

    We study the phenomenology of models of electroweak symmetry breaking where the Higgs potential is destabilized by a tadpole arising from the coupling to an “auxiliary” Higgs sector. The auxiliary Higgs sector can be either perturbative or strongly coupled, similar to technicolor models. Since electroweak symmetry breaking is driven by a tadpole, the cubic and quartic Higgs couplings can naturally be significantly smaller than their values in the standard model. The theoretical motivation for these models is that they can explain the 125 GeV Higgs mass in supersymmetry without fine-tuning. The auxiliary Higgs sector contains additional Higgs states that cannot decouple from standard model particles, so these models predict a rich phenomenology of Higgs physics beyond the standard model. In this paper we analyze a large number of direct and indirect constraints on these models. We present the current constraints after the 8 TeV run of the LHC, and give projections for the sensitivity of the upcoming 14 TeV run. We find that the strongest constraints come from the direct searches A 0 →Zh, A 0 →tt-bar, with weaker constraints from Higgs coupling fits. For strongly-coupled models, additional constraints come from ρ + →WZ where ρ + is a vector resonance. Our overall conclusion is that a significant parameter space for such models is currently open, allowing values of the Higgs cubic coupling down to 0.4 times the standard model value for weakly coupled models and vanishing cubic coupling for strongly coupled models. The upcoming 14 TeV run of the LHC will stringently test this scenario and we identify several new searches with discovery potential for this class of models.

    Ravn, Susanne

    research, researchers involve in describing lived bodies and lived experiences to further explore and understand the diversities of our embodied practices and experiences. The aim of this paper is to present and discus some of the methodological challenges of combining phenomenology and qualitative...... methodologies. I will specifically focus on discussing how the transcendental orientation of phenomenological descriptions has the potential to work through difference by approaching lived bodies according to their lived situation. The discussion will fall in three parts focusing on: a) how the research design...... in the practices; c) how the researcher can handle and ‘go beyond’ the subjective and situated descriptions in analyses when aiming at accounting for the structure of subjective experiences. In descriptions and discussions I draw on my current research of movement practices related to different kinds and genre...

  16. 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

  17. Politique CERN pour le contrôle d'accès à son domaine et description de l'implantation en cours

    Jacot, C

    1998-01-01

    Une volonté politique claire émanant de la direction du CERN et de l'Access Control Panel a chargé la section ST/MC/AC de mettre en place un concept de contrôle d'accès global et cohérent pour l'ensemble des accès au domaine et aux sites de ses accélérateurs. Cela implique que depuis l'accueil et l'enregistrement des personnes jusqu'à la gestion, la surveillance du domaine ainsi que les installations techniques de contrôle d'accès, tous ces services qui sont complémentaires sont désormais rassemblés dans une seule section. Un projet de management des autorisations fortement informatisé ainsi que la productions des cartes CERN sont en cours d'installation. De nombreuses autres installations de contrôle d'accès sont opérationnelles et d'autres sont en cours de réalisation. Toutes seront ensuite intégrées et supervisées depuis une centrale située dans le bâtiment 120, cette dernière est exploitée par une société de surveillance au bénéfice d'un contrat avec le CERN.

    Sébastien Sacré

    2013-11-01

    Full Text Available En cette époque de mondialisation, la mise en valeur des cultures minoritaires est, dans les milieux universitaires, de plus en plus importante. Cependant, ce développement d’une conscience culturelle est bien moins évidents dans le cadre de cours de langue, dont objectif principal n’est pas l’apprentissage d’une culture, mais celui d’une langue-cible. Ainsi, les langues et leurs cultures associées ont beau être indissociables par nature, il est cependant les enseigner séparément. Enseigner la langue en ne parlant de culture que superficiellement n’est cependant pas sans conséquences et il n’est pas rare de remarquer, dans manuels de langue par exemple, une représentation superficielle, voire stéréotypée du monde. Comment peut-on conjuguer l’apprentissage d’une langue à celui de ses richesses culturelles ? Basé sur des expériences d’enseignement et sur de récents manuels d’apprentissage, cet article se proposera d’analyser les difficultés et les défis de l’intégration d’éléments culturels dans des cours de type Français Langue Seconde.

  19. New results in light-front phenomenology

    Brodsky, S.J.

    2005-01-01

    The light-front quantization of gauge theories in light-cone gauge provides a frame-independent wavefunction representation of relativistic bound states, simple forms for current matrix elements, explicit unitarity, and a trivial vacuum. In this talk I review the theoretical methods and constraints which can be used to determine these central elements of QCD phenomenology. The freedom to choose the light-like quantization four-vector provides an explicitly covariant formulation of light-front quantization and can be used to determine the analytic structure of light-front wave functions and define a kinematical definition of angular momentum. The AdS/CFT correspondence of large N c supergravity theory in higher-dimensional anti-de Sitter space with supersymmetric QCD in four-dimensional space-time has interesting implications for hadron phenomenology in the conformal limit, including an all-orders demonstration of counting rules for exclusive processes. String/gauge duality also predicts the QCD power-law behavior of light-front Fock-state hadronic wavefunctions with arbitrary orbital angular momentum at high momentum transfer. The form of these near-conformal wavefunctions can be used as an initial ansatz for a variational treatment of the light-front QCD Hamiltonian. The light-front Fock-state wavefunctions encode the bound state properties of hadrons in terms of their quark and gluon degrees of freedom at the amplitude level. The nonperturbative Fock-state wavefunctions contain intrinsic gluons, and sea quarks at any scale Q with asymmetries such as s(x) ≠ s-bar(x), u-bar(x) ≠ d-bar(x). Intrinsic charm and bottom quarks appear at large x in the light-front wavefunctions since this minimizes the invariant mass and off-shellness of the higher Fock state. In the case of nuclei, the Fock state expansion contains 'hidden color' states which cannot be classified in terms of of nucleonic degrees of freedom. I also briefly review recent analyses which show that some

  20. The cruel and unusual phenomenology of solitary confinement.

    Gallagher, Shaun

    2014-01-01

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

  5. The Theory and Phenomenology of Love

    Paolo Borsa

    2017-05-01

    Full Text Available This second issue of Interfaces: A Journal fo Medieval European Literatures addresses the subject of "The Theory and Phenomenology of Love." It brings together readings of medieval representations and explanations of love as an affection, passion, sentiment, attraction, or tension, with work on the connections between literary discourses of love and the history both of emotions and gender roles. Approaching the subject of the nature of love, and the ways it manifests itself, the authors create links between scientific and poetic discourse and highlight the relationship between the experiences of love, described and treated in literary texts, and the specific historical, cultural, and social environments in which those texts were produced. Not only do the articles reach original results within their fields; taken as a whole, the dossier, ranging as it does from the Late Antiquity to the fifteenth century, and across a Europe situated within a wider Eurasian space, offers deep insights into social history, the history of emotions, and the study of gender and sexuality.

  6. Constrained Sypersymmetric Flipped SU (5) GUT Phenomenology

    We explore the phenomenology of the minimal supersymmetric flipped SU(5) GUT model (CFSU(5)), whose soft supersymmetry-breaking (SSB) mass parameters are constrained to be universal at some input scale, Min, above the GUT scale, M{sub GUT}. We analyze the parameter space of CFSU(5) assuming that the lightest supersymmetric particle (LSP) provides the cosmological cold dark matter, paying careful attention to the matching of parameters at the GUT scale. We first display some specific examples of the evolutions of the SSB parameters that exhibit some generic features. Specifically, we note that the relationship between the masses of the lightest neutralino {chi} and the lighter stau {tilde {tau}}{sub 1} is sensitive to M{sub in}, as is the relationship between m{sub {chi}} and the masses of the heavier Higgs bosons A,H. For these reasons, prominent features in generic (m{sub 1/2}, m{sub 0}) planes such as coannihilation strips and rapid-annihilation funnels are also sensitive to Min, as we illustrate for several cases with tan {beta} = 10 and 55. However, these features do not necessarily disappear at large Min, unlike the case in the minimal conventional SU(5) GUT. Our results are relatively insensitive to neutrino masses.

  8. Phenomenological charge-dependent forces in nuclei

    Kasymbalinov, R.N.; Sapershtein, E.E.

    1984-01-01

    The Nolen-Schiffer anomaly and the double Coulomb differences, i.e., mass differences of mirror nuclei differing by two nucleons, are considered together. It is shown that in the calculation of these differences one must take into account a renormalization of the Coulomb amplitude because of the polarization of the core and also include the ''tail effect,'' i.e., the difference of the single-particle wave functions of the protons and neutrons. These two effects have been ignored in earlier work on this subject. It has turned out that the latter effect is particularly important, and its sign depends on the character of the density dependence of the amplitude GAMMA/sup xi/ responsible for pairing. The phenomenological non-Coulomb charge-dependent forces, the introduction of which permits elimination of the Nolen--Schiffer anomaly, make it possible to reproduce also the double Coulomb differences only if one assumes that the amplitude GAMMA/sup xi/ corresponds to the surface pairing

  9. Phenomenological model for H-mode

    Ohyabu, N.

    1985-08-01

    A phenomenological model has been developed to clarify the role of the boundary configuration in the heat transport of the H-mode regime. We assume that the dominant mechanism of heat loss at the edge of the plasma is convection and that the diffusion coefficient (D/sub edge/) at the edge of the plasma increases rapidly with plasma pressure, but drops to a low value when the temperature exceeds a certain threshold value. When particle refueling takes place without time delay, as in the case of a limiter discharge, the unfavorable temperature dependence of the D/sub edge/ prohibits even a modest rise of the edge temperature. In a divertor discharge, the particles lost from the closed surface are kept away from the edge region for a time comparable to or longer than the energy transport time in the edge region. Thus, rapid increase in the heat flux allows an excursion of the edge temperature to a higher value thereby reaching the threshold value of the H-transition

  10. Spin-one top partner: phenomenology

    Collins, Jack H.; Jain, Bithika; Perelstein, Maxim; Lorier, Nicolas Rey-Le

    2014-08-01

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

  11. Phenomenology of the next sequential lepton

    Rizzo, T.G.

    1980-01-01

    We consider the phenomenology of a sequential, charged lepton in the mass range 6 --13 GeV. We find the semileptonic branching ratio of such a lepton to be approx. 13%; the dominant two-body modes are found to include the decay L → ν/sub L/F* with a branching ratio approx. 6%. In this analysis we assume that the mass of the lepton under consideration is lighter than the t quark such that decays such as L → ν/sub L/t-barq, where q= (d, s, or b) are kinematically forbidden. We also find that decays such as L → ν/sub L/B* (c-barb) can also be as large as approx. 6% depending on the mixing angles; the lifetime of such a lepton is found to be approx. 2.6 x 10 -12 M/sub L/ -5 sec, where M/sub L/ is in GeV

  12. Phenomenology of Compositeness at the LHC

    Salvioni, Ennio; Zwirner, Fabio

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

  13. Phenomenological modeling of abradable wear in turbomachines

    Berthoul, Bérenger; Batailly, Alain; Stainier, Laurent; Legrand, Mathias; Cartraud, Patrice

    2018-01-01

    Abradable materials are widely used as coatings within compressor and turbine stages of modern aircraft engines in order to reduce operating blade-tip/casing clearances and thus maximize energy efficiency. However, rubbing occurrences between blade tips and coating liners may lead to high blade vibratory levels and endanger their structural integrity through fatigue mechanisms. Accordingly, there is a need for a better comprehension of the physical phenomena at play and for an accurate modeling of the interaction, in order to predict potentially unsafe events. To this end, this work introduces a phenomenological model of the abradable coating removal based on phenomena reported in the literature and accounting for key frictional and wear mechanisms including plasticity at junctions, ploughing, micro-rupture and machining. It is implemented within an in-house software solution dedicated to the prediction of full three-dimensional blade/abradable coating interactions within an aircraft engine low pressure compressor. Two case studies are considered. The first one compares the results of an experimental abradable test rig and its simulation. The second one deals with the simulation of interactions in a complete low-pressure compressor. The consistency of the model with experimental observations is underlined, and the impact of material parameter variations on the interaction and wear behavior of the blade is discussed. It is found that even though wear patterns are remarkably robust, results are significantly influenced by abradable coating material properties.

  14. Nucleon-nucleon theory and phenomenology

    Signell, P.

    1981-03-01

    This project involves five inter-related subprojects: (1) derivation of the intermediate range nucleon-nucleon interaction using a new method that utilizes much shorter and simpler analytic continuation through the unphysical region that lies between the πN and ππ physical regions of the N anti N → ππ amplitude (with significantly improved accuracy for the nucleon-nucleon interaction); (2) construction of a short range phenomenological potential that, with the theoretical part mentioned above, gives a precise fit to the nucleon-nucleon data and is parameterized for easy use in nucleon calculations; (3) phase shift analyses of the world data below 400 MeV, especially the large amount of very precise data below 20 MeV and the new data near 55 MeV that have never been analyzed properly; (4) the introduction of a K-matrix formulation of the Optimal Polynomial Expansion in order to accelerate convergence of the partial wave series at LAMPF energies; and (5) setting up of a cooperatively evaluated permanent nucleon-nucleon data bank in the 0-1200 MeV range that can be used by all nucleon-nucleon reseachers

  15. A general phenomenological model for work function

    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.

  16. Automated adaptive inference of phenomenological dynamical models

    Daniels, Bryan

    Understanding the dynamics of biochemical systems can seem impossibly complicated at the microscopic level: detailed properties of every molecular species, including those that have not yet been discovered, could be important for producing macroscopic behavior. The profusion of data in this area has raised the hope that microscopic dynamics might be recovered in an automated search over possible models, yet the combinatorial growth of this space has limited these techniques to systems that contain only a few interacting species. We take a different approach inspired by coarse-grained, phenomenological models in physics. Akin to a Taylor series producing Hooke's Law, forgoing microscopic accuracy allows us to constrain the search over dynamical models to a single dimension. This makes it feasible to infer dynamics with very limited data, including cases in which important dynamical variables are unobserved. We name our method Sir Isaac after its ability to infer the dynamical structure of the law of gravitation given simulated planetary motion data. Applying the method to output from a microscopically complicated but macroscopically simple biological signaling model, it is able to adapt the level of detail to the amount of available data. Finally, using nematode behavioral time series data, the method discovers an effective switch between behavioral attractors after the application of a painful stimulus.

  17. Phenomenology of convection-parameterization closure

    J.-I. Yano

    2013-04-01

    Full Text Available Closure is a problem of defining the convective intensity in a given parameterization. In spite of many years of efforts and progress, it is still considered an overall unresolved problem. The present article reviews this problem from phenomenological perspectives. The physical variables that may contribute in defining the convective intensity are listed, and their statistical significances identified by observational data analyses are reviewed. A possibility is discussed for identifying a correct closure hypothesis by performing a linear stability analysis of tropical convectively coupled waves with various different closure hypotheses. Various individual theoretical issues are considered from various different perspectives. The review also emphasizes that the dominant physical factors controlling convection differ between the tropics and extra-tropics, as well as between oceanic and land areas. Both observational as well as theoretical analyses, often focused on the tropics, do not necessarily lead to conclusions consistent with our operational experiences focused on midlatitudes. Though we emphasize the importance of the interplays between these observational, theoretical and operational perspectives, we also face challenges for establishing a solid research framework that is universally applicable. An energy cycle framework is suggested as such a candidate.

  18. ‘Firewall’ phenomenology with astrophysical neutrinos

    Afshordi, Niayesh; Yazdi, Yasaman K.

    2016-12-01

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

    2017-04-20

    We perform a general study of the relic density and LHC constraints on simplified models where the dark matter coannihilates with a strongly interacting particle X. In these models, the dark matter depletion is driven by the self-annihilation of X to pairs of quarks and gluons through the strong interaction. The phenomenology of these scenarios therefore only depends on the dark matter mass and the mass splitting between dark matter and X as well as the quantum numbers of X. In this paper, we consider simplified models where X can be either a scalar, a fermion or a vector, as well as a color triplet, sextet or octet. We compute the dark matter relic density constraints taking into account Sommerfeld corrections and bound state formation. Furthermore, we examine the restrictions from thermal equilibrium, the lifetime of X and the current and future LHC bounds on X pair production. All constraints are comprehensively presented in the mass splitting versus dark matter mass plane. While the relic density constraints can lead to upper bounds on the dark matter mass ranging from 2 TeV to more than 10 TeV across our models, the prospective LHC bounds range from 800 to 1500 GeV. A full coverage of the strongly coannihilating dark matter parameter space would therefore require hadron colliders with significantly higher center-of-mass energies.

  3. Phenomenology of 2HDM with vectorlike quarks

    Arhrib, A.; Benbrik, R.; King, S. J. D.; Manaut, B.; Moretti, S.; Un, C. S.

    2018-05-01

    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.

  4. Phenomenology of Flavon Fields at the LHC

    Tsumura, Koji; Velasco-Sevilla, Liliana

    2009-11-01

    We study low energy constraints from flavour violating processes, production and decay at the LHC of a scalar field φ (flavon) associated to the breaking of a non supersymmetric Abelian family symmetry at the TeV scale. This symmetry is constrained to reproduce fermion masses and mixing, up to O(1) coefficients. The non-supersymmetric gauged U(1) models considered are severely restricted by cancellation of anomalies and LEP bounds on contact interactions, consequently its phenomenology is out of the LHC reach. We therefore introduce an effective U(1) which is not gauged and it is broken explicitly by a CP odd term at the TeV scale. This help us to explore flavour violating processes, production and decay at the LHC for these kind of light scalars. In this context we first study the constraints on the flavon mass and its vacuum expectation value from low energy flavour changing processes such as μ→ eγ. We find that a flavon of about m φ φ >∼ m t , and τμ-bar for m t , which could be effectively useful to detect flavons. (author)

  5. Extraordinary phenomenology from warped flavor triviality

    Delaunay, Cedric; Gedalia, Oram; Lee, Seung J.; Perez, Gilad; Ponton, Eduardo

    2011-01-01

    Anarchic warped extra dimensional models provide a solution to the hierarchy problem. They can also account for the observed flavor hierarchies, but only at the expense of little hierarchy and CP problems, which naturally require a Kaluza-Klein (KK) scale beyond the LHC reach. We have recently shown that when flavor issues are decoupled, and assumed to be solved by UV physics, the framework's parameter space greatly opens. Given the possibility of a lower KK scale and composite light quarks, this class of flavor triviality models enjoys a rather exceptional phenomenology, which is the focus of this Letter. We also revisit the anarchic RS EDM problem, which requires m KK ≥12 TeV, and show that it is solved within flavor triviality models. Interestingly, our framework can induce a sizable differential tt-bar forward-backward asymmetry, and leads to an excess of massive boosted di-jet events, which may be linked to the recent findings of the CDF Collaboration. This feature may be observed by looking at the corresponding planar flow distribution, which is presented here. Finally we point out that the celebrated standard model preference towards a light Higgs is significantly reduced within our framework.

  6. [MENTORING IN NURSING, A PHENOMENOLOGICAL APPROACH].

    Osuna Torres, Blanca Herlinda; González Rendón, M C E Cristina

    2014-11-01

    The essay explains that mentoring, originally established to improve student trajectories, reflects a deeper improvement of the people involved in the process. The method used is the analysis of the mentoring experience from participant observation and phenomenology of lived processes. The results reveal that the early analysis of risk factors present in academics--socio-psychological, family and institutional matters, that may affect the student experience in its passage through the academic unit--, requires the intervention of a preventive nature and monitoring operating variables. In addition, tutoring is a teaching experience which is consolidated with the daily life from the human relationship established between the mentor and the mentee, from the position of the older adult and experience is a state meet demand related care. However, in the tutorial process face to face, usually with academic aspects, therefore, the teaching function is fulfilled but operated in particular. By helping to find meaning to knowledge not understood, this function is still performed if tutors pairs learn to know each other that occasionally is the mirror which reflects the own story. While they are recognizing the problems of the mentee, the mentor will exorcise his ghosts. Therefore, we argue that, although originally born tutoring to abate dropout rates, failure and increase retention and degree, over time, has become a process of improving people.

  7. A phenomenological view of language shift.

    Tsitsipis, Lukas D

    2004-01-01

    Sociolinguistic studies of language shift have in their majority framed their research object in a horizon of theoretically received variables such as class, ethnicity, locality, attitudes etc. In spite of a limited usefulness of such conceptual variables, and of a recently emerging focus on agency, negotiation, and praxis the best results we obtain have not questioned in a coherent and theoretically sound manner the continuing hegemony of mechanistic-metaphorical models (language death, language suicide). In this paper I propose to examine language shift as a multifaceted phenomenon, joining in this respect work by other linguistic anthropologists researching similar areas. I specifically argue that by replacing vertical concepts such as age and generation, and dichotomous logics such as center and periphery with phenomenologically inspired concepts such as typifications, consociateship, contemporariness, and stream of consciousness we are in a better position to generalize about language shift dynamics. Data for this work is derived primarily from the Albanian speech communities of modern Greece, but also from other communities for comparative purposes.

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

    Porter, E J

    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.

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.

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.

  4. Evolution de certains composés volatils du bois de chêne au cours de son séchage premiers résultats

    Pascal Chatonnet

    1994-12-01

    Full Text Available Pendant le séchage des merrains sur parc à l'air libre, on assiste à une profonde modification de la composition chimique et du profil aromatique du bois de chêne. La teneur en eugénol, en aldéhydes phénols et en Β-méthyl-y-octalactone augmente régulièrement pendant le vieillissement du bois. Principalement sous forme trans au début du séchage, la Β-méthyl-y-octalactone s'accumule finalement sous la forme cis plus aromatique. Dans le même temps, on observe également une accumulation importante du précurseur inodore de Β-méthyl-y-octalactone. L'intervention des micro-organismes fréquemment isolés sur le bois en cours de séchage naturel sur la formation de composés aromatiques a été étudiée. La culture de diverses moisissures isolées de bois en cours de séchage naturel sur extraits de bois et directement sur sciure de chêne aboutit dans tous les cas à une forte diminution des teneurs en aldéhydes phénols, notamment de la vanilline. En effet, tous les micro-organismes étudiés (Penicilium sp., Trichoderma sp., Aureobasidium sp. sont incapables de dégrader la lignine car ils ne possèdent pas d'activité ligninase. En revanche, ces champignons possèdent une forte activité oxydo-réductase capable de réduire la vanilline en alcool vanillique inodore. En conséquence, les aldéhydes phénols apparaissant au cours du séchage naturel du merrain ne dérivent pas d'une attaque enzymatique mais plus vraisemblablementde l'acidolyse et de l'oxydation chimique de la lignine du bois. Le stockage du bois à l'air libre en présence d'eau et d'oxygène doit permettre une évolution favorable de son potentiel aromatique tant que la vanilline et la cis Β-méthyly-octalactone s'accumulent.

  5. 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.

  6. Hegelian Phenomenology of Spirit and Boxing Fight

    Kosiewicz Jerzy

    2018-03-01

    Full Text Available In the presented text the author points out to anthropological as well as axiological foundations of the boxing fight from the viewpoint of Hegel’s philosophy. In the genial idealist’s views it is possible to perceive the appreciation of the body, which constitutes a necessary basis for the man’s physical activity, for his work oriented towards the self-transformation and the transformation of the external world, as well as for rivalry and the hand-to-hand fight. While focusing our attention on the issue of rivalry and on the situation of the fight - and regarding it from the viewpoint of the master - slave theory (included in the phenomenology of spirit, it is possible to proclaim that even a conventionalised boxing fight - that is, restricted by cultural and sports rules of the game - has features of the fight to the death between two Hegelian forms of selfknowledge striving for self-affirmation and self-realisation. In the boxing fight, similarly as in the above mentioned Hegelian theory, a problem of work and of the development of the human individual (that is, of the subject, self-knowledge, the participant of the fight appears. There appears also a prospect of death as a possible end of merciless rivalry. The fight revalues the human way in an important way, whereas the prospect for death, the awareness of its proximity, the feeling that its close and possible, saturates the life with additional values. It places the boxer, just like every subject fighting in a similar or a different way, on the path towards absolute abstraction - that is, it brings him closer to his self-fulfilment in the Absolute, to the absolute synthesis. The Hegelian viewpoint enables also to appreciate the boxing fight as a manifestation of low culture (being in contrast with high culture, to turn attention to the relations which - according to Hegel - take place between the Absolute and the man, as well as to show which place is occupied by the subject both in

  7. Phenomenology with supersymmetric flipped SU(6)

    Shafi, Qaisar E-mail: shafi@bartol.udel.edu; Tavartkiladze, Zurab E-mail: tavzur@axpfe1.fe.infn.it

    1999-07-12

    The supersymmetric flipped SU(6) x U(1) gauge symmetry can arise through compactification of the ten-dimensional E{sub 8} x E{sub 8} superstring theory. We show how realistic phenomenology can emerge from this theory by supplementing it with the symmetry R x U(1), where R denotes a discrete 'R'-symmetry. The well-known doublet-triplet splitting problem is resolved to 'all orders' via the pseudo-Goldstone mechanism, and the GUT scale arises from an interplay of the Planck and supersymmetry breaking scales. The symmetry R x U(1) is also important for understanding the fermion mass hierarchies as well as the magnitudes of the CKM matrix elements. Furthermore, the well-known MSSM parameter tan {beta} is estimated to be of order unity, while the proton lifetime ({tau}{sub p} {approx} 10{sup 2}{tau}{sub pSU(5)}) is consistent with observations. Depending on some parameters, p {yields} K{mu}{sup +} can be the dominant decay mode. Finally, the observed solar and atmospheric neutrino 'anomalies' requir us to introduce a 'sterile' neutrino state. Remarkably, the R x U(1) symmetry protects it from becoming heavy, so that maximal angle {nu}{sub {mu}} oscillations into a sterile state can explain the atmospheric anomaly, while the solar neutrino puzzle is resolved via the small angle {nu}{sub e} - {nu}{sub {tau}} MSW oscillations. The existence of some ({approx} 15-20% of critical energy density) neutrino hot dark matter is also predicted.

  8. Light-cone quantization and QCD phenomenology

    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

  9. Birth of a science centre. Italian phenomenology

    Paola Rodari

    2006-06-01

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

    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.

  13. Phenomenology of flavor-mediated supersymmetry breaking

    Kaplan, D. Elazzar; Kribs, Graham D.

    2000-01-01

    The phenomenology of a new economical supersymmetric model that utilizes dynamical supersymmetry breaking and gauge mediation for the generation of the sparticle spectrum and the hierarchy of fermion masses is discussed. Similarities between the communication of supersymmetry breaking through a messenger sector and the generation of flavor using the Froggatt-Nielsen (FN) mechanism are exploited, leading to the identification of vector-like messenger fields with FN fields and the messenger U(1) as a flavor symmetry. An immediate consequence is that the first and second generation scalars acquire flavor-dependent masses, but do not violate flavor changing neutral current bounds since their mass scale, consistent with ''effective supersymmetry,'' is of order 10 TeV. We define and advocate a ''minimal flavor-mediated model'' (MFMM), recently introduced in the literature, which successfully accommodates the small flavor-breaking parameters of the standard model using order 1 couplings and ratios of flavon field VEVs. The mediation of supersymmetry breaking occurs via two-loop logarithm-enhanced gauge-mediated contributions, as well as several one-loop and two-loop Yukawa-mediated contributions for which we provide analytical expressions. The MFMM is parametrized by a small set of masses and couplings, with values restricted by several model constraints and experimental data. Full two-loop renormalization group evolution is performed, correctly taking into account the negative two-loop gauge contributions from heavy first and second generations. Electroweak symmetry is radiatively broken with the value of μ determined by matching to the Z mass. The weak scale spectrum is generally rather heavy, except for the lightest Higgs boson, the lightest stau, the lightest chargino, the lightest two neutralinos, and of course a very light gravitino. The next-to-lightest sparticle always has a decay length that is larger than the scale of a detector, and is either the lightest stau

  14. Le rôle du Conseil de Sécurité de l’Organisation des Nations unies dans les travaux de la Cour Pénale Internationale

    Germana Aguiar Ribeiro do Nascimento

    2016-10-01

    Full Text Available Le Conseil de sécurité est un organe politique soucieux du maintien de la paix et de la sécurité internationales. La Cour pénale internationale, quant à elle, est un organe juridictionnel subsidiaire qui a pour vocation de juger les crimes de guerre, de génocide, d’agression et les crimes contre l’humanité. Ces deux organes ont comme dénominateur commun le maintien de la paix et de la sécurité internationales. Cette convergence de compétences a été consacrée par le Statut de Rome en octroyant au Conseil de sécurité la prérogative de saisir la Cour. L’intervention du Conseil de sécurité dans le fonctionnement de la Cour peut ainsi être bénéfique pour assurer les droits de l’Homme, néanmoins, elle peut représenter un frein à l’effectivité de l’exercice de la compétence de la Cour. Dans cette optique, il serait intéressant d’aborder l’aspect constructif du lien qui unit la Cour et le Conseil de sécurité, ainsi que l’obstacle qu’il peut représenter pour la réalisation de la paix et de la sécurité internationales. Pour cela, la méthodologie qualitative sera utilisée. La recherche documentaire, l’étude de la jurisprudence et de la législation permettront de regrouper les renseignements relatifs au sujet.

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

    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.

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.

  17. The Role of Phenomenology of Merleau- ponty in Medicine

    2017-07-01

    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.

  19. van Manen's method and reduction in a phenomenological hermeneutic study.

    Heinonen, Kristiina

    2015-03-01

    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.

  20. Phenomenological characteristics of autobiographical memory in Korsakoff's syndrome.

    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.

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

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

    2016-05-01

    The vantage perspective from which a memory is retrieved influences the memory's emotional impact, intrusiveness, and phenomenological characteristics. This study tested whether similar effects are observed when participants were instructed to imagine the events from a specific perspective. Fifty student participants listened to a verbal report of car-accidents and visualized the scenery from either a field or observer perspective. There were no between-condition differences in emotionality of memories and the number of intrusions, but imagery experienced from a relative observer perspective was rated as less self-relevant. In contrast to earlier studies on memory retrieval, vantage perspective influenced phenomenological memory characteristics of the memory representation such as sensory details, and ratings of vividness and distancing of the memory. However, vantage perspective is most likely not a stable phenomenological characteristic itself. Implications and suggestions for future research are discussed. Copyright © 2016 Elsevier Inc.

  3. Understanding the Key Tenets of Heidegger’s Philosophy for Interpretive Phenomenological Research

    Marcella Horrigan-Kelly

    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.

  4. The cruel and unusual phenomenology of solitary confinement

    Gallagher, Shaun

    2014-01-01

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

  6. Mobile Technosoma: some phenomenological reflections on itinerant media devices

    Ingrid Richardson

    2005-01-01

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

  8. Phenomenology from SIDIS and e+e- multiplicities: multiplicities and phenomenology - part I

    Bacchetta, Alessandro; Echevarria, Miguel G.; Radici, Marco; Signori, Andrea

    2015-01-01

    This study is part of a project to investigate the transverse momentum dependence in parton distribution and fragmentation functions, analyzing (semi-)inclusive high-energy processes within a proper QCD framework. We calculate the transverse-momentum-dependent (TMD) multiplicities for e+e- annihilation into two hadrons (considering different combinations of pions and kaons) aiming to investigate the impact of intrinsic and radiative partonic transverse momentum and their mixing with flavor. Different descriptions of the non-perturbative evolution kernel (see, e.g., Refs. [1-5]) are available on the market and there are 200 sets of flavor configurations for the unpolarized TMD fragmentation functions (FFs) resulting from a Monte Carlo fit of Semi-Inclusive Deep-Inelastic Scattering (SIDIS) data at Hermes (see Ref. [6]). We build our predictions of e+e- multiplicities relying on this rich phenomenology. The comparison of these calculations with future experimental data (from Belle and BaBar collaborations) will shed light on non-perturbative aspects of hadron structure, opening important insights into the physics of spin, flavor and momentum structure of hadrons.

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

    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.

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

    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.

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

    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.

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

    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 discuss...

    L'objectif de ce travail est de rapporter une observation particulière de myélome multiple survenant au cours d'une maladie périodique. Il s'agit d'un patient tunisien de 53 ans suivi depuis le jeune âge pour maladie périodique dont le diagnostic était confirmé par l’étude génétique montrant l'homozygotie pour la mutation M694V du gène MEFV, fut admis pour exploration d'une douleur avec tuméfaction fessière droite récente. Les explorations biologiques et radiologiques ont permis de retenir le diagnostic d'un myélome multiple de type IgA à chaînes légères kappa stade III B, associé à une volumineuse localisation plasmocytaire très agressive de l'aile iliaque droite envahissant les structures musculaires avoisinantes.

  5. Introducing Postphenomenological Research: A Brief and Selective Sketch of Phenomenological Research Methods

    Aagaard, Jesper

    2017-01-01

    In time, phenomenology has become a viable approach to conducting qualitative studies in education. Popular and well-established methods include descriptive and hermeneutic phenomenology. Based on critiques of the essentialism and receptivity of these two methods, however, this article offers a third variation of empirical phenomenology:…

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

    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. An empathy, as a model of extrapolation of the principle (of to be get used to the experience of the Other onto mystical act of overcoming of subject

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

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

    2011-01-01

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

  8. A phenomenological evaluation: using storytelling as a primary teaching method.

    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.

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

    Oscar Parcero Oubiña

    2016-12-01

    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.

  10. [Driving modes of the interview in phenomenological research: experience report].

    de Paula, Cristiane Cardoso; Padoin, Stela Maris de Mello; Terra, Marlene Gomes; Souza, Ivis Emília de Oliveira; Cabral, Ivone Evangelista

    2014-01-01

    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.

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

    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.

  12. Phenomenological reports diagnose accuracy of eyewitness identification decisions.

    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.

  13. Phenomenology of a nonstandard Higgs boson in WLWL scattering

    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

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

    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

    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. Phenomenological aspects of heterotic orbifold models at one loop

    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

    Close, F E

    1975-01-01

    A general introduction to coloured quark models is given and their phenomenology is described with particular reference to the new particles. 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.

  20. Continuity of phenomenology and (in)consistency of content of meaningful autobiographical memories.

    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.

  5. Relating Schizotypy and Personality to the Phenomenology of Creativity

    Nelson, B.; Rawlings, D.

    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

    Hwa, R. C.; Pisut, J.; Pisutova, N.

    2000-01-01

    The data of J/psi suppression at large x_F in pA collisions are used to infer the existence of gluon depletion as the projectile proton traverses the nucleus. The modification of the gluon distribution is studied by use of a convolution equation whose non-perturbative splitting function is determined phenomenologically. The depletion factor at x_1=0.8 is found to be about 25% at A=100.

  9. Inductive approach towards a phenomenologically more satisfactory unififed field theory

    Rayski, J.; Rayski, J.M. Jnr.

    1985-01-01

    A unified field theory constituting a fusion of the ideas of supersymmetries with general relativity and gauge theory is investigated. A Lagrangian formalism is constructed step by step; the last step consists in a marriage with Kaluza's idea of a multidimensional space-time. Our aim is not to achieve a full local supersymmetry in eleven dimensions, but rather to attain a compromise with the symmetries of the fundamental interactions either known phenomenologically, or only suspected to exist in nature

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

    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.

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

    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.

    Krasilnikov Igor Aleksandrovich

    2013-05-01

    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. The significant attention is given R. Meya's to sights, as one of the main representatives of existential psychotherapy. Practical implications. Preparation of psychologists in the field of psychotherapeutic consultation.

  13. 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.

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

    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

  15. Physics on smallest scales. An introduction to minimal length phenomenology

    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.)

  17. Mechanisms for dominance in an early successional old field by the invasive non-native Lespedeza cuneata (Dum. Cours.) G. Don

    Researchers studying invasive plants often concentrate their efforts on predictive models thought to allow invasive plants to dominate native landscapes. However, if an invasive is already well established then experimental research is necessary to provide the information necessary to effectively manage the species. Prescribing appropriate management strategies without prior experimental research may not only be ineffective but also may squander limited resources or have the unintended consequence of furthering spread. Lespedeza cuneata (Dum. Cours.) G. Don. is a well-established invasive plant of old fields and tall-grass prairie in the US. Managers suspect this species shades-out native plants and this is proposed as its primary mechanism for dominance. Using field experiments we tested probable factors allowing the speices to establish itself and once established, interfere in old field plant communities. We also examined the effects of two common anthropogenic disturbances (mowing and nutrients) on L. cuneata growth and establishment. When L. cuneata was treated (clipping, herbicide and stem pull-back) there was a significant increase in species richness and native speices cover. Stem density and canopy cover of L. cuneata increased significantly with mowing frequency but decreased with nutrient input. We suggest that mowing benefits L. cuneata while also hindering woody competition. Results also indicate L. cuneata is less prevalent on nutrient enriched soils than on unamended soil. Lespedeza cuneata appears to suppress native plants by shading them out and it can subsequently take over grassland communities. Since it has a varying response to human induced disturbances and may actually benefit from mowing, land managers should be cautious when utilizing this as a management tool.

  18. Influences de la symphonie concertante sur la musique de la Cour parisienne sous l'Empire et la Restauration (1800-1830

    Dratwicki, Alexandre

    2003-12-01

    Full Text Available The origins of the very much appreciated "symphonie concertante" can be found in the importance of public concerts given in Paris at the end of the 18th century. The specific repertoire played at the French Court during the years 1800-1830 distinctly shows this vogue for the "symphonie concertante", for it reveals the still unknown importance of virtuosity. Considered as an musical entertainment for the pompous parties at the French Court or as an musical accompaniment for the masses given at the Imperial and Royal Chapel, this "decorative concertant syle" became an essential part of the Regime etiquette during the Napoleonic empire as well as the Restoration period. This music, perfectly incorporated into the official guidelines, will disappear as a consequence of the political events of 1830 and the arrival of a new aesthetic movement, the Romanticism.

    [fr] La vogue du concert public à Paris, à la fin du XVIIIe siècle, fut à l'origine de l'essor phénoménal que connut la symphonie concertante. Le répertoire de la musique de la Cour - entre 1800 et 1830 - est particulièrement représentatif de cette mode : il révèle une place encore insoupçonnée laissée à la virtuosité. Agrémentant les messes de la Chapelle ou les bals donnés lors de fastueuses soirées, ce « style concertant décoratif » devint un élément constitutif de l'apparat gouvernemental sous l'Empire et la Restauration. Une sorte d'académisme officiel que les événements politiques de 1830 et l'essor du romantisme musical feront définitivement disparaître.

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

    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.

    Guerrero-Castañeda, Raúl Fernando; Menezes, Tânia Maria de Oliva; Vargas, Ma Guadalupe Ojeda

    2017-01-01

    To report our experience using scenario approximation in a phenomenological study of nursing in Mexico. Experience report on scenario approximation to coexist with elderly in order to select the participants of a phenomenological study. During a four-month period in 2016, visits were carried out two groups of elderly individuals where several activities were carried out. Coexistence with the elderly throughout accompaniment in the groups' activities together with joint dialogue allowed selection of those who corresponded to the characteristics of the study objective. Scenario approximation is necessary in phenomenological studies, not only for creating empathy among the participants but also for the researchers to immerse themselves in the phenomenon under study, as shown by the first approaches of the researcher. Relatar la experiencia del acercamiento al escenario de un estudio fenomenológico en enfermería en México. Relato de experiencia sobre el acercamiento al escenario de estudio para convivir con adultos mayores con la finalidad de seleccionar a los participantes de un estudio fenomenológico. Se llevaron a cabo visitas durante el año 2016, en un periodo de cuatro meses a dos grupos de adultos mayores en donde se realizaron diversas actividades. La convivencia con los adultos mayores a través del acompañamiento en las actividades que realizaban en los grupos y el diálogo conjunto permitió seleccionar a aquellos que respondían a las características del objeto de estudio. Es necesaria la aproximación al escenario de estudios fenomenológicos, no sólo con la finalidad de ganar empatía de los participantes sino para sumergirse en el fenómeno de estudio, mismo que se va mostrando desde los primeros acercamientos del investigador.

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

    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.

    Full Text Available The purpose of the study was to investigate differences in perceived student satisfaction in blended and online learning environments based on personality type. A total of 72 graduate students enrolled in blended and online courses at two research universities in the United States completed an abbreviated online version of the Myers-Briggs Type Indicator (MBTI® and an online student satisfaction questionnaire. Overall, results indicate participants were satisfied with courses delivered in both environments. Analyses revealed several significant differences in perceived student satisfaction with certain elements in blended and online courses based on personality type. Cette étude a pour but d'examiner si la satisfaction des étudiants à l’égard d’environnements d'apprentissage hybride et en ligne varie en fonction du type de personnalité. 72 étudiants de cycle supérieur inscrits dans des cours hybrides et en ligne de deux universités de recherche américaines ont rempli en ligne une version abrégée de l'indicateur de types psychologiques de MyersBriggs (MBTI ® ainsi qu’un questionnaire mesurant le niveau de satisfaction des étudiants. Dans l'ensemble, les résultats indiquent que les participants étaient satisfaits des cours enseignés dans ces deux environnements. Les analyses ont révélé que la satisfaction des étudiants à l’égard de certains éléments des cours hybrides et en ligne varie en fonction du type de personnalité.

    Full Text Available Cet article envisage les délibérés des cours d’assises, en premier ressort et en appel, de l’affaire d’Outreau, à partir des auditions de la commission d’enquête parlementaire, et à la lumière d’une expérience professionnelle de magistrat (17 années comme juge des enfants, 16 années comme président d'assises. Cette libre projection permet de parcourir, à partir des textes de loi, des pratiques de conduites de délibérés. Il s'agit aussi d'aborder les problèmes inhérents au traitement judiciaire pénal des affaires de mœurs, et leurs spécificités en matière de recherche des preuves de culpabilité, tant en raison de la charge émotionnelle de ces dossiers, que de leur retentissement dans la société française d'aujourd'hui.This article deals with the deliberations in the Cour d’assises in the Outreau case, both in the first resort and in appeal, by using the hearings before the Parliamentary investigation committee and the author’s professional experience as a judge (17 years as children’s judge and 16 years as a President in the Cour d’assises. This free personal reflection gives the opportunity, by using the legal texts, to think over the practices of deliberation. The author also examines the problems inherent to the criminal proceedings in the sex cases and the specificity of evidence of guilt in such cases both because of their emotive power and because of the considerable stir they create in French public opinion nowadays.

    Full Text Available Dans cet article, nous présentons la mise en œuvre, l’expérimentation et l’évaluation d’une approche pour la recommandation des chemins d’apprentissage dans un cours en ligne. Le processus de recommandation est inspiré de l’intelligence en essaim et plus particulièrement de l’optimisation par colonies de fourmis (OCF (ant colony optimization [ACO]. Dans ce contexte, nous avons considéré une différenciation des chemins d’apprentissage en fonction de l’activité explorée pour l’apprentissage d’un cours. Dans l’objectif de recommander des chemins d’apprentissage considérés optimaux et d’évaluer ainsi leur impact sur l’apprentissage d’un cours en ligne, l’approche proposée est basée à la fois sur la recommandation de chemins pertinents par l’enseignant et sur les résultats stockés au fur et à mesure par les apprenants sur les chemins empruntés. Notre approche a été validée expérimentalement et les résultats obtenus ont montré l’émergence d’un chemin d’apprentissage favorisant la réussite d’un nombre d’apprenants relativement considérable.

  7. Horizontal unification as the phenomenology of the theory of 'everything'

    Sakharov, A.S.; Khlopov, M.Yu.

    1994-01-01

    It is shown that the extension of the standard electroweak model and QCD, which contains the spontaneously broken horizontal local gauge symmetry, provides quantatively definite phenomenological descriprion for all the phenomena of particle physics and cosmology. The model connects the predictions of the standard model with the description of the mass spectrum and mixing of quarks and leptons, with the predictions of neutrino mass spectrum and with parameters of invisible axion. It provides quantatively definite physical basis for the theory of inflation, baryosynthesis and dark matter of the Universe. 34 refs

  8. Phenomenological Hints from a Class of String Motivated Model Constructions

    Hans Peter Nilles

    2015-01-01

    Full Text Available We use string theory constructions towards the generalisation of the supersymmetric standard model of strong and electroweak interactions. Properties of the models depend crucially on the location of fields in extradimensional compact space. This allows us to extract some generic lessons for the phenomenological properties of the low energy effective action. Within this scheme we present a compelling model based on local grand unification and mirage mediation of supersymmetry breakdown. We analyse the properties of the specific model towards its possible tests at the LHC and the complementarity to direct dark matter searches.

  9. A Simple Introduction to Grobner Basis Methods in String Phenomenology

    2011-01-01

    I give an elementary introduction to the key algorithm used in recent applications of computational algebraic geometry to the subject of string phenomenology. I begin with a simple description of the algorithm itself and then give 3 examples of its use in physics. I describe how it can be used to obtain constraints on flux parameters, how it can simplify the equations describing vacua in 4D string models, and lastly how it can be used to compute the vacuum space of the electroweak sector of the MSSM.

  10. Alternative approaches to research in physical therapy: positivism and phenomenology.

    Shepard, K F; Jensen, G M; Schmoll, B J; Hack, L M; Gwyer, J

    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.

  11. Phenomenological study of the isovector tensor meson family

    Pang, Cheng-Qun; He, Li-Ping; Liu, Xiang; Matsuki, Takayuki

    2014-07-01

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

    Full Text Available Given the difficulty in demonstrating the moment of ontogenesis in which personalization takes place, we sought to define, from a philosophic point of view, the nature of the human embryo regarding its individuality, using Phenomenology, specifically reflections of philosophers Bourghet and Merleau-Ponty on the embryo. Although the statement of their individuality does not entail ethical content in itself, from the point of view of ethical responsibility, it is an extremely important fact to be considered in the bioethical reflection about the moment of ontogeny from which human life must (ethical duty be protected.

  13. LHC collider phenomenology of minimal universal extra dimensions

    Beuria, Jyotiranjan; Datta, AseshKrishna; Debnath, Dipsikha; Matchev, Konstantin T.

    2018-05-01

    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.

  14. Deflected Mirage Mediation: A Phenomenological Framework for Generalized Supersymmetry Breaking

    Everett, Lisa L.; Kim, Ian-Woo; Ouyang, Peter; Zurek, Kathryn M.

    2008-01-01

    We present a general phenomenological framework for dialing between gravity mediation, gauge mediation, and anomaly mediation. The approach is motivated from recent developments in moduli stabilization, which suggest that gravity mediated terms can be effectively loop suppressed and thus comparable to gauge and anomaly mediated terms. The gauginos exhibit a mirage unification behavior at a ''deflected'' scale, and gluinos are often the lightest colored sparticles. The approach provides a rich setting in which to explore generalized supersymmetry breaking at the CERN Large Hadron Collider

  16. Women's perspectives toward menopause: A phenomenological study in Iran.

    Hakimi, Sevil; Simbar, Masoumeh; Ramezani Tehrani, Fahimeh; Zaiery, Farid; Khatami, Shiva

    2016-01-01

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

  17. Quantum-Gravity Phenomenology of soft ultraviolet/infrared mixing

    Amelino-Camelia, Giovanni; Loret, Niccolo; Mercati, Flavio

    2010-01-01

    We reexamine the motivation for ultraviolet/infrared mixing in quantum gravity and some of the quantum-spacetime formalizations where it has been found. We then focus on cases in which the infrared manifestations of the mixing are relatively soft, arguing that they can motivate a particularly appealing phenomenology. Among the possible implications for the large-distance behavior of gravity one intriguingly finds a correction with logarithmic dependence on distance. And one can explain in terms of soft ultraviolet/infrared mixing a four-standard-deviation discrepancy that was recently established in the context of studies of cold neutrons.

  18. Phenomenology of spinless adjoints in two universal extra dimensions

    Ghosh, Kirtiman; Datta, Anindya

    2008-01-01

    We discuss the phenomenology of (1,1)-mode adjoint scalars in the framework of two Universal Extra Dimensions. The Kaluza-Klein (KK) towers of these adjoint scalars arise in the 4-dimensional effective theory from the 6th component of the gauge fields after compactification. Adjoint scalars can have KK-number conserving as well as KK-number violating interactions. We calculate the KK-number violating operators involving these scalars and two Standard Model fields. Decay widths of these scalars into different channels have been estimated. We have also briefly discussed pair-production and single production of such scalars at the Large Hadron Collider

  19. Banal and Implied Forms of Violence in Levinas' Phenomenological Ethics

    Fleurdeliz R. Altez

    2007-06-01

    Full Text Available Despite his final call for peace and "the wisdom of love", Emmanuel Levinas inevitably spoke of violence, and perhaps spoke even more of it. His call for infinite responsibility is actually crystallized through discourse on violence and suffering. We may say that these themes served as catalysts to the standing theory and, ethically, to any responsible Self. Violence, at least as a concept, poses itself as a significant presence to Levinas' plantilla while it reaches unexplored dimensions that await phenomenology and vital thought. As a part of his ethical proposal, understanding violence becomes important so that the Self may go beyond it while reaching the Other.

  20. Approximate deconvolution models of turbulence analysis, phenomenology and numerical analysis

    Layton, William J

    2012-01-01

    This volume presents a mathematical development of a recent approach to the modeling and simulation of turbulent flows based on methods for the approximate solution of inverse problems. The resulting Approximate Deconvolution Models or ADMs have some advantages over more commonly used turbulence models – as well as some disadvantages. Our goal in this book is to provide a clear and complete mathematical development of ADMs, while pointing out the difficulties that remain. In order to do so, we present the analytical theory of ADMs, along with its connections, motivations and complements in the phenomenology of and algorithms for ADMs.

  1. The phenomenological method in qualitative psychology and psychiatry.

    2016-01-01

    This article will closely examine the phenomenological method as applied to qualitative inquiry in psychology and psychiatry. In a critical comparison between Amedeo Giorgi's and Larry Davidson's qualitatively methods, conclusions were drawn with regard to how different kinds of qualitative inquiry are possible while remaining faithful to Husserlian philosophical foundations. Utilizing Lester Embree's recent articulation of how Husserl's method of the epochē can be disclosed as specific to a discipline, varieties of these two qualitative methods were seen in their relation to the original scientific aim instigated by the developer.

    The size of the gluon distribution at small χ has important implications for phenomenology at future high energy hadron-hadron and lepton-hadron colliders. We extend a recent global parton distribution fit to investigate the constraints on the gluon from deep inelastic and prompt photon data. In particular, we estimate a band of allowed gluon distributions with qualitatively small-χ behaviour and study the implications of these on a variety of cross sections at high energy pp and ep colliders.

  5. Abelian realization of phenomenological two-zero neutrino textures

    R. González Felipe

    2014-09-01

    Full Text Available In an attempt at explaining the observed neutrino mass-squared differences and leptonic mixing, lepton mass matrices with zero textures have been widely studied. In the weak basis where the charged lepton mass matrix is diagonal, various neutrino mass matrices with two zeros have been shown to be consistent with the current experimental data. Using the canonical and Smith normal form methods, we construct the minimal Abelian symmetry realizations of these phenomenological two-zero neutrino textures. The implementation of these symmetries in the context of the seesaw mechanism for Majorana neutrino masses is also discussed.

  6. Multiscale modeling of complex materials phenomenological, theoretical and computational aspects

    Trovalusci, Patrizia

    2014-01-01

    The papers in this volume deal with materials science, theoretical mechanics and experimental and computational techniques at multiple scales, providing a sound base and a framework for many applications which are hitherto treated in a phenomenological sense. The basic principles are formulated of multiscale modeling strategies towards modern complex multiphase materials subjected to various types of mechanical, thermal loadings and environmental effects. The focus is on problems where mechanics is highly coupled with other concurrent physical phenomena. Attention is also focused on the historical origins of multiscale modeling and foundations of continuum mechanics currently adopted to model non-classical continua with substructure, for which internal length scales play a crucial role.

    We derive a closed, model independent, expression for the electromagnetic correction factor to a phenomenological hadronic scattering length a h extracted from a hydrogenic atom. It is obtained in a non-relativistic approach and in the limit of a short ranged hadronic interaction to terms of order α 2 logα using an extended charge distribution. A hadronic πN scattering length a h π - p =0.0870(5)m π -1 is deduced leading to a πNN coupling constant from the GMO relation g c 2 /(4π)=14.04(17)

  9. Phenomenological constraints on light mixed sneutrino dark matter scenarios

    Mitsuru Kakizaki

    2015-10-01

    Full Text Available In supersymmetric models with Dirac neutrinos, the lightest sneutrino can be a good thermal dark matter candidate when the soft sneutrino trilinear parameter is large. In this paper, we focus on scenarios where the mass of the mixed sneutrino LSP is of the order of GeV so the sneutrino dark matter is still viable complying with the limits by current and near future direct detection experiments. We investigate phenomenological constraints in the parameter space of the models, as well as the vacuum stability bound. Finally, we show that the allowed regions can be explored by measuring Higgs boson properties at future collider experiments.

  10. Interpretive Phenomenological Analysis: An Appropriate Methodology for Educational Research?

    Edward John Noon

    2018-04-01

    Full Text Available Interpretive phenomenological analysis (IPA is a contemporary qualitative methodology, first developed by psychologist Jonathan Smith (1996. Whilst its roots are in psychology, it is increasingly being drawn upon by scholars in the human, social and health sciences (Charlick, Pincombe, McKellar, & Fielder, 2016. Despite this, IPA has received limited attention across educationalist literature. Drawing upon my experiences of using IPA to explore the barriers to the use of humour in the teaching of Childhood Studies (Noon, 2017, this paper will discuss its theoretical orientation, sampling and methods of data collection and analysis, before examining the strengths and weaknesses to IPA’s employment in educational research.

  11. Identification and communication of uncertainties of phenomenological models in PSA

    Pulkkinen, U.; Simola, K.

    2001-11-01

    This report aims at presenting a view upon uncertainty analysis of phenomenological models with an emphasis on the identification and documentation of various types of uncertainties and assumptions in the modelling of the phenomena. In an uncertainty analysis, it is essential to include and document all unclear issues, in order to obtain a maximal coverage of unresolved issues. This holds independently on their nature or type of the issues. The classification of uncertainties is needed in the decomposition of the problem and it helps in the identification of means for uncertainty reduction. Further, an enhanced documentation serves to evaluate the applicability of the results to various risk-informed applications. (au)

  12. SURVIE EMBRYONNAIRE DU SAUMON ATLANTIQUE (SALMO SALAR L. DANS UN COURS D’EAU DU SUD DE SON AIRE DE RÉPARTITION, LA NIVELLE

    Full Text Available L’évaluation de la survie du saumon Atlantique entre la ponte et l’émergence des alevins hors des graviers est réalisée dans le bassin de la Nivelle dans les domaines accessible (trois tronçons et non accessible (trois tronçons aux géniteurs. Pour ce faire, des capsules d’incubation de 12 cm3, contenant des œufs fraîchement fécondés, sont insérées dans des frayères artificielles et naturelles. Le débit et la température de l’eau de surface, l’oxygène dissous des eaux de surface et interstitielle et les caractéristiques granulométriques du substrat des frayères sont contrôlés pendant toute la durée de l’expérience. La survie, de 28,6 % en moyenne dans l’ensemble des sites, est plus élevée dans les tronçons de l’amont (52,7 % dans la Très Haute Nivelle et son affluent, le Lapitxuri que dans les autres sites, dont ceux actuellement colonisés par l’espèce (21,5 %. Il n’est pas observé de différence de survie entre les frayères artificielles et naturelles. Les mortalités interviennent essentiellement lors des épisodes de crues avant l’éclosion. Une corrélation positive forte existe entre la saturation en oxygène de l’eau interstitielle et la survie. Pour une saturation minimum en oxygène au-dessous de 62 %, la survie reste inférieure à 27 %. En revanche, la composition granulométrique du substrat ne semble pas agir directement sur la survie. Ce facteur n’étant pas corrélé avec l’oxygène dissous, ceci suggère que dans ce cours d’eau, le flux circulant dans les frayères ne provient pas uniquement de l’eau de surface, mais aussi de la nappe alluviale pauvre en oxygène dissous.

    1984-01-01

    Interpretation of nonspheric atomic nuclei spectra on the basis of phenomenological hamiltonians of SU(3) model showed satisfactory agreement of simulation calculations with experimental data. Meanwhile physical sense of phenomenological hamiltonians was not yet discussed. It is shown that phenomenological hamiltonians of SU(3) model are reduced to hamiltonian of nonaxial rotator but with additional items of the third and fourth powers angular momentum operator of rotator

    Dante Gabriel Duero

    2015-03-01

    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.

  18. Internally consistent gamma ray burst time history phenomenology

    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

  19. Origin and phenomenology of weak-doublet spin-1 bosons

    Chizhov, M.V.; Dvali, Gia

    2011-01-01

    We study phenomenological consequences of the Standard Model extension by the new spin-1 fields with the internal quantum numbers of the electroweak Higgs doublets. We show, that there are at least three different classes of theories, all motivated by the hierarchy problem, which predict appearance of such vector weak-doublets not far from the weak scale. The common feature for all the models is the existence of an SU(3) W gauge extension of the weak SU(2) W group, which is broken down to the latter at some energy scale around TeV. The Higgs doublet then emerges as either a pseudo-Nambu-Goldstone boson of a global remnant of SU(3) W , or as a symmetry partner of the true eaten-up Goldstone boson. In the third class, the Higgs is a scalar component of a high-dimensional SU(3) W gauge field. The common phenomenological feature of these theories is the existence of the electroweak doublet vectors (Z * ,W * ), which in contrast to well-known Z ' and W ' bosons posses only anomalous (magnetic moment type) couplings with ordinary light fermions. This fact leads to some unique signatures for their detection at the hadron colliders.

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

    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

  1. LHC phenomenology of composite 2-Higgs doublet models

    De Curtis, Stefania [University of Florence, Department of Physics and Astronomy, Sesto Fiorentino (Italy); INFN, Sezione di Firenze (Italy); Moretti, Stefano; Yagyu, Kei; Yildirim, Emine [University of Southampton, School of Physics and Astronomy, Southampton (United Kingdom)

    2017-08-15

    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.

  2. Socio-phenomenological perspective of the bureaucratic organizational structure

    Jairo E. Cuenú Cabezas

    2011-12-01

    Full Text Available To accomplish their purposes in carrying out their activities, organizations need a structure. The word structure is used by different disciplines, which - in general terms - conceive it as an order-relation. In organizational theory, the word structure essentially defines the relationships amongst individuals to reach a given end. The organizational structure is a product of the interaction of human beings and it is they, from their experiences, rationalities, and expectations, who determine how the purposes should be accomplished. Different forms exist, in terms of structure, to accomplish organizational purposes; one of the most representative forms is the bureaucratic approach. Bureaucracy is a method to use special abilities. This cannot be denied, but it is also a form, from Alfred Schütz’ phenomenological sociology, of establishing settings of intimacy and anonymity in organizational relations. The objective of this article is to show how the bureaucratic structure generates intimacy or anonymity in the organization. In the first place, the article presents the concept of structure from which the organizational structure is explained, especially the bureaucratic structure. The second part presents Alfred Schütz’ phenomenological sociology, emphasizing on the concept he raised of the world of everyday life and the relations of otherness. With the aforementioned, intimacy and anonymity in the organization is developed or explained. In conclusion, among other aspects, we address the need for the organizational theory or for organizational theorists to approach everyday life in organizations

  3. Beyond a code of ethics: phenomenological ethics for everyday practice.

    Greenfield, Bruce; Jensen, Gail M

    2010-06-01

    Physical therapy, like all health-care professions, governs itself through a code of ethics that defines its obligations of professional behaviours. The code of ethics provides professions with a consistent and common moral language and principled guidelines for ethical actions. Yet, and as argued in this paper, professional codes of ethics have limits applied to ethical decision-making in the presence of ethical dilemmas. Part of the limitations of the codes of ethics is that there is no particular hierarchy of principles that govern in all situations. Instead, the exigencies of clinical practice, the particularities of individual patient's illness experiences and the transformative nature of chronic illnesses and disabilities often obscure the ethical concerns and issues embedded in concrete situations. Consistent with models of expert practice, and with contemporary models of patient-centred care, we advocate and describe in this paper a type of interpretative and narrative approach to moral practice and ethical decision-making based on phenomenology. The tools of phenomenology that are well defined in research are applied and examined in a case that illustrates their use in uncovering the values and ethical concerns of a patient. Based on the deconstruction of this case on a phenomenologist approach, we illustrate how such approaches for ethical understanding can help assist clinicians and educators in applying principles within the context and needs of each patient.

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

    Chao, Wei [Beijing Normal University, Center for Advanced Quantum Studies, Department of Physics, Beijing (China)

    2018-02-15

    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{sub R} from Z-Z{sup '} mixing as well as the upper bound of Z{sup '} production cross section in di-lepton channel at the LHC are presented. We further study the neutrino mass and the phenomenology of Z{sub R}-portal dark matter in this model. The lightest right-handed neutrino can be the cold dark matter candidate stabilized by a Z{sub 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{sup '} mixing only for g{sub R} < 0.121, where g{sub R} is the new gauge coupling.

  5. Proceedings, phenomenology and applications of high temperature superconductors

    Bedell, K.S.

    1991-01-01

    Phenomenology and Applications of High Temperature Superconductors, The Los Alamos Symposium: 1991, was sponsored by the Los Alamos National Laboratory, Center for Materials Science, the Advanced Studies Program on High Temperature Superconductivity Theory (ASP) and the Exploratory Research and Development Center. This is the second symposium in the series. High Temperature Superconductivity, The Los Alamos Symposium: 1989, also published by Addison Wesley, focused on the cutting-edge theoretical and experimental issues in high temperature superconductors. This symposium, with its focus on the phenomenology and applications of high temperature superconductors, gives a complementary review of the aspects of the field closely related to the impact of high temperature superconductors on technology. The objective of ASP is to advance the field on a broad front with no specific point of view by bringing a team of leading academic theorists into a joint effort with the theoretical and experimental scientists of a major DOE national laboratory. The ASP consisted of fellows led by Robert Schrieffer (UCSB and now FSU) joined by David Pines (University of illinois), Elihu Abrahams (Rutgers), Sebastian Doniach (Stanford), and Maurice Rice (ETH, Zurich) and theoretical and experimental staff of Los Alamos National Laboratory. This synergism of academic, laboratory, theoretical and experimental research produced a level of interaction and excitement that would not be possible otherwise. This publication and the previous one in the series are just examples of how this approach to advancing science can achieve significant contributions

  6. DECONSTRUCTION OF THE METAPHYSICS OF PRESENCE IN PHENOMENOLOGY AND STRUCTURALISM

    A. A. Polivoda

    2017-06-01

    Full Text Available Purpose of the work is a description of critical position of J. Derrida on metaphysics of presence in phenomenological and structuralist discourses. As a philosophical strategy, deconstruction tries to destroy a violent hierarchy of terms, in which one term dominates the other according to its ontological or rational sense. Methodology of research is based on J. Derrida’s strategy of deconstruction, which tries to undermine the basic principles of knowledge and Western philosophy existence, for example, the opposition between nature and culture. In terms of J. Derrida, to deconstruct Western philosophy means to explore the tensions and contradictions in text, which should clarify false reliability of accepted hierarchies. The originality of the work lies in the identification of metaphysic of presence problem in structuralist and phenomenological discourses through the deconstruction project. Deconstruction should show instability of logocentrism, which focuses on repression of writing in terms of thought, truth, reason or logic. Conclusions: J. Derrida’s deconstruction appeared as an attempt to overthrow metaphysics and get focused on the concept of writing, which scope is limited by discourse. Deconstruction of metaphysics of presence is a continuous request of legitimacy of the existing logocentrism, and search of its weaknesses, aporias and contradictions, which make impossible the tradition, centered around mind.

  7. Destruction as a Step in Heidegger\\'s Phenomenology

    M.J Safian

    2014-09-01

    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.

  8. Listening to Schneiderian Voices: A Novel Phenomenological Analysis.

    Rosen, Cherise; Chase, Kayla A; Jones, Nev; Grossman, Linda S; Gin, Hannah; Sharma, Rajiv P

    This paper reports on analyses designed to elucidate phenomenological characteristics, content and experience specifically targeting participants with Schneiderian voices conversing/commenting (VC) while exploring differences in clinical presentation and quality of life compared to those with voices not conversing (VNC). This mixed-method investigation of Schneiderian voices included standardized clinical metrics and exploratory phenomenological interviews designed to elicit in-depth information about the characteristics, content, meaning, and personification of auditory verbal hallucinations. The subjective experience shows a striking pattern of VC, as they are experienced as internal at initial onset and during the longer-term course of illness when compared to VNC. Participants in the VC group were more likely to attribute the origin of their voices to an external source such as God, telepathic communication, or mediumistic sources. VC and VNC were described as characterological entities that were distinct from self (I/we vs. you). We also found an association between VC and the positive, cognitive, and depression symptom profile. However, we did not find a significant group difference in overall quality of life. The clinical portrait of VC is complex, multisensory, and distinct, and suggests a need for further research into the biopsychosocial interface between subjective experience, socioenvironmental constraints, individual psychology, and the biological architecture of intersecting symptoms. © 2016 S.

  9. The vulnerability to schizophrenia mainstream research paradigms and phenomenological directions.

    Stanghellini, Giovanni; Fusar-Poli, Paolo

    2012-01-01

    Early psychopathological attempts to characterize the vulnerability to schizophrenia were based on the phenomenological method. From the beginning, phenomenologically-oriented psychopathologists have searched the basic vulnerability underlying schizophrenic phenomena in two main domains: depersonalization and derealisation/desocialization. Schizophrenic persons undergo a special kind of depersonalisation: the living body becomes a functioning body, a thing-like mechanism in which feelings, perceptions, and actions take place as if they happened in an outer space. They also endure a special kind of derealisation/de-socialization: the interpersonal scene becomes like a theatre stage, pervaded with a sense of unreality, on which the main actor is unaware of the plot, out of touch with the role he is acting and unable to make sense of the objects he encounters and of what the other people are doing. Many years later, the mainstream research paradigms employed to investigate the vulnerability concept in schizophrenic psychosis have included genetic studies, birth cohort studies, psychosis proneness, and clinical high risk. We will review these studies and conclude with an outline of future research directions focusing on three main features of the psychopathology of early schizophrenia: anomalies of the pre-reflexive self and of the social self (intersubjectivity), and existential re-orientation.

  10. Consistent microscopic and phenomenological analysis of composite particle opticle potential

    Mukhopadhyay, Sheela; Srivastava, D.K.; Ganguly, N.K.

    1976-01-01

    A microscopic calculation of composits particle optical potential has been done using a realistic nucleon-helion interaction and folding it with the density distribution of the targets. The second order effects were simulated by introducing a scaling factor which was searched on to reproduce the experimental scattering results. Composite particle optical potential was also derived from the nucleon-nucleus optical potential. The second order term was explicitly treated as a parameter. Elastic scattering of 20 MeV 3 H on targets ranging from 40 Ca to 208 Pb to 208 Pb have also been analysed using phenomenological optical model. Agreement of these results with the above calculations verified the consistency of the microscopic theory. But the equivalent sharp radius calculated with n-helion interaction was observed to be smaller than phenomenological value. This was attributed to the absence of saturation effects in the density-independent interaction used. Saturation has been introduced by a density dependent term of the form (1-c zetasup(2/3)), where zeta is the compound density of the target helion system. (author)

  11. TOPICAL PROBLEMS: The phenomenological theory of world population growth

    Kapitza, Sergei P.

    1996-01-01

    Of all global problems world population growth is the most significant. Demographic data describe this process in a concise and quantitative way in its past and present. Analysing this development it is possible by applying the concepts of systems analysis and synergetics, to work out a mathematical model for a phenomenological description of the global demographic process and to project its trends into the future. Assuming self-similarity as the dynamic principle of development, growth can be described practically over the whole of human history, assuming the growth rate to be proportional to the square of the number of people. The large parameter of the theory and the effective size of a coherent population group is of the order of 105 and the microscopic parameter of the phenomenology is the human lifespan. The demographic transition — a transition to a stabilised world population of some 14 billion in a foreseeable future — is a systemic singularity and is determined by the inherent pattern of growth of an open system, rather than by the lack of resources. The development of a quantitative nonlinear theory of the world population is of interest for interdisciplinary research in anthropology and demography, history and sociology, for population genetics and epidemiology, for studies in evolution of humankind and the origin of man. The model also provides insight into the stability of growth and the present predicament of humankind, and provides a setting for discussing the main global problems.

  12. Psychosocial needs of burns nurses: a descriptive phenomenological inquiry.

    Kornhaber, Rachel Anne; Wilson, Anne

    2011-01-01

    The purpose of this qualitative study was to explore the psychosocial needs of nurses who care for patients with severe burn injuries. Burns nurses work in an emotionally challenging and confronting environment, for which they are in need of emotional and clinical support. Exposure to such high levels of stress in this occupational environment has implications for nurses' health and psychosocial well-being. Seven burns nurses were recruited in 2009 from a severe burn injury unit in New South Wales, Australia. A qualitative phenomenological methodology was used to construct themes depicting nurses' experiences. Participants were selected through purposeful sampling, and data were collected through in-depth individual semistructured interviews using open-ended questions. Data were analyzed with Colaizzi's phenomenological method of data analysis. The psychosocial needs of burns nurses were identified and organized into five categories: peer nursing support, informal support, lack of support, multidisciplinary team collaboration, and professional support. The findings clearly demonstrate that support and unity within the workplace are fundamental factors for the psychosocial well-being of nurses caring for patients who have sustained a severe burn injury. Support for nurses in the form of regular professional or collegial debriefing sessions and utilization of employee assistance programs could ease the impact of the stressful environment in which they operate, and could influence staff retention. However, a supportive workplace culture is necessary to encourage nurses to access these services.

  13. Phenomenological modeling of turbulence in Z-pinch implosions

    Thornhill, J.W.; Whitney, K.G.; Deeney, C.; LePell, P.D.

    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

    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.

    Full Text Available L'utilisation des diatomées et des indices diatomiques dans les réseaux français de mesure de la qualité des eaux a débuté en 1970, sur la Seine. Un regain d'intérêt s'est manifesté à partir des années 1990, avec des applications sur les bassins Rhône-Méditerranée-Corse, Artois- Picardie, Rhin-Meuse et Adour-Garonne. En 1994, les Agences se sont associées avec le CEMAGREF pour mettre au point un indice diatomique applicable en routine sur l'ensemble du territoire français, et pour promouvoir et faciliter son utilisation en réseau de surveillance. Cet indice diatomique doit rejoindre l'Indice Biologique Global Normalisé au sein du volet biologique du futur système d'évaluation de la qualité des cours d'eau, actuellement en cours de réalisation. Les développements doivent désormais porter sur la consolidation de cet indice au niveau français, ainsi que sur des tests dans plusieurs pays européens.

    Highlights: • Phenomenological model for annular flow dryout is presented. • The model evaluates initial entrained fraction using a new methodology. • The history effect in annular flow is predicted and validated. • Rod bundle dryout is predicted using subchannel methodology. • Model is validated against experimental dryout data in tubes and rod bundles. - Abstract: Analysis and prediction of dryout is of important consequence to safety of nuclear fuel clusters of boiling water type of reactors. Traditionally, experimental correlations are used for dryout predictions. Since these correlations are based on operating parameters and do not aim to model the underlying phenomena, there has been a proliferation of the correlations, each catering to some specific bundle geometry under a specific set of operating conditions. Moreover, such experiments are extremely costly. In general, changes in tested bundle geometry for improvement in thermal-hydraulic performance would require re-experimentation. Understanding and modeling the basic processes leading to dryout in flow boiling thus has great incentive. Such a model has the ability to predict dryout in any rod bundle geometry, unlike the operating parameter based correlation approach. Thus more informed experiments can be carried out. A good model can, reduce the number of experiments required during the iterations in bundle design. In this paper, a phenomenological model as indicated above is presented. The model incorporates a new methodology to estimate the Initial Entrained Fraction (IEF), i.e., entrained fraction at the onset of annular flow. The incorporation of this new methodology is important since IEF is often assumed ad-hoc and sometimes also used as a parameter to tune the model predictions to experimental data. It is highlighted that IEF may be low under certain conditions against the general perception of a high IEF due to influence of churn flow. It is shown that the same phenomenological model is

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

    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

    The focus of this thesis is on the phenomenology of several non-minimal supersymmetric models in the context of future linear colliders (LCs). Extensions of the minimal supersymmetric Standard Model (MSSM) may accommodate the observed Higgs boson mass at about 125 GeV in a more natural way than the MSSM, with a richer phenomenology. We consider both F-term extensions of the MSSM, as for instance the non-minimal supersymmetric Standard Model (NMSSM), as well as D-terms extensions arising at low energies from gauge extended supersymmetric models. The NMSSM offers a solution to the μ-problem with an additional gauge singlet supermultiplet. The enlarged neutralino sector of the NMSSM can be accurately studied at a LC and used to distinguish the model from the MSSM. We show that exploiting the power of the polarised beams of a LC can be used to reconstruct the neutralino and chargino sector and eventually distinguish the NMSSM even considering challenging scenarios that resemble the MSSM. Non-decoupling D-terms extensions of the MSSM can raise the tree-level Higgs mass with respect to the MSSM. This is done through additional contributions to the Higgs quartic potential, effectively generated by an extended gauge group. We study how this can happen and we show how these additional non-decoupling D-terms affect the SM-like Higgs boson couplings to fermions and gauge bosons. We estimate how the deviations from the SM couplings can be spotted at the Large Hadron Collider (LHC) and at the International Linear Collider (ILC), showing how the ILC would be suitable for the model identication. Since our results prove that a linear collider is a fundamental machine for studying supersymmetry phenomenology at a high level of precision, we argue that also a thorough comprehension of the physics at the interaction point (IP) of a LC is needed. Therefore, we finally consider the possibility of observing intense electromagnetic field effects and nonlinear quantum electrodynamics

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

    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.

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

    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.

    2012-01-01

    The recent transition to full composite fuselages is a major breakthrough in aeronautical design. To ensure satisfactory lightning protection, the electrical properties of the primary composite structure need to be improved and a design solution lies on bonding a metallic fishnet to the fuselage. An important issue is the prediction of the aging behavior of this top layer when exposed to severe aging conditions representative of flight environment. Multiple aging mechanisms affect this top layer made of thermoset resin and metallic fishnet with complex geometry and a first modeling strategy is a necessary starting point to better understand its evolution. This paper describes the overall phenomenology and the different mechanisms that can be expected in such a structure.

  15. Phenomenological classification of cultural heritage: role of virtual reality

    Hyuk-Jin Lee

    2017-05-01

    Full Text Available Human consciousness is always the consciousness toward some thing and our perception of cultural heritage is no exception. Thus, understanding human cognition is closely related to understanding how the perceptible objects are classified in human mind. The perceptible objects include both physical and virtual experiences and thoughts, and it is important and necessary to analyze the types and the effective levels of those objects. With the emergence of Virtual Reality (VR technologies in cultural heritage field, it is necessary to understand how and why different cognitive media such as realor visual reality including VR, are differently recognized by people. This study suggests the philosophical and theoretical frame for the usage of phenomenological classfication and analysis. By using this new classification with the case of Korean built heritage, the role of VR is explained in cultural discourse of the community.

  16. Obsessionality & compulsivity: a phenomenology of obsessive-compulsive disorder.

    Denys, Damiaan

    2011-02-01

    Progress in psychiatry depends on accurate definitions of disorders. As long as there are no known biologic markers available that are highly specific for a particular psychiatric disorder, clinical practice as well as scientific research is forced to appeal to clinical symptoms. Currently, the nosology of obsessive-compulsive disorder is being reconsidered in view of the publication of DSM-V. Since our diagnostic entities are often simplifications of the complicated clinical profile of patients, definitions of psychiatric disorders are imprecise and always indeterminate. This urges researchers and clinicians to constantly think and rethink well-established definitions that in psychiatry are at risk of being fossilised. In this paper, we offer an alternative view to the current definition of obsessive-compulsive disorder from a phenomenological perspective.

  17. Engagement and practical wisdom in clinical practice: a phenomenological study.

    Saraga, Michael; Boudreau, Donald; Fuks, Abraham

    2018-05-08

    In order to understand the lived experiences of physicians in clinical practice, we interviewed eleven expert, respected clinicians using a phenomenological interpretative methodology. We identified the essence of clinical practice as engagement. Engagement accounts for the daily routine of clinical work, as well as the necessity for the clinician to sometimes trespass common boundaries or limits. Personally engaged in the clinical situation, the clinician is able to create a space/time bubble within which the clinical encounter can unfold. Engagement provides an account of clinical practice as a unitary lived experience. This stands in stark contrast to the prevailing notion, referred to as a dual discourse, that describes medicine as the addition of humanism to science. Drawing on Aristotle's notion of phronesis and Sartre's definition of the situation, we illustrate how this novel perspective entwines clinical practice, the person of the clinician, and the clinician's situation.

  18. A phenomenological Hamiltonian for the Lotka-Volterra problem

    Georgian, T.; Findley, G.L.

    1996-01-01

    We have presented a Hamiltonian theory of phenomenological chemical kinetics. In the present paper, we extend this treatment to the Lotka-Volterra model of sustained oscillations. Our approach begins with the usual definition of an intrinsic reaction coordinate space (x 1 ,x 2 ) for the Lotka-Volterra problem, which leads to the rate equations x 1 =ax 1 -bx 1 x 2 , x 2 =-cx 2 +bx 1 x 2 , with a,b and c being real constants. We thereafter present a Hamiltonian function H(x,y)[y 1 = x 1 and y 2 = x 2 ] and an associated holonomic constraint, which give rise to the above rates as half of Hamilton's equations. We provide trajectories by numerical integration (4th order Runge-Kutta) and show that H(x,y) is a constant of the motion. Finally, issues involved in developing an analytic solution to this problem are discussed

  20. Organic food as a healthy lifestyle: A phenomenological psychological analysis

    Von Essen, Elisabeth; Englander, Magnus

    2013-01-01

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