    2017-01-01

    Theoretical advances in dynamical-systems theory and their applications to pattern-forming processes in the sciences and engineering are discussed in this volume that resulted from the conference Patterns in Dynamics held in honor of Bernold Fiedler, in Berlin, July 25-29, 2016.The contributions build and develop mathematical techniques, and use mathematical approaches for prediction and control of complex systems. The underlying mathematical theories help extract structures from experimental observations and, conversely, shed light on the formation, dynamics, and control of spatio-temporal patterns in applications. Theoretical areas covered include geometric analysis, spatial dynamics, spectral theory, traveling-wave theory, and topological data analysis; also discussed are their applications to chemotaxis, self-organization at interfaces, neuroscience, and transport processes. .

    Full Text Available Fiedler has theory which is called “contingency model”. According to him, if an organization attempts to achieve group effectiveness through leadership, then there is a need to assess the leader according to an underlying trait, assess the situation faced by the leader, and construct a proper match between the two. With Fiedler model, researchers were doing assessment to one of the student organization in Bina Nusantara University, which is BNCC 22nd student committee. The result of the research is that student organization in this case two committees from BNCC show two different results. The first one does not fit with Fiedler model, which is the “people oriented” leader can make an effective leadership, and the second one with “people oriented” leader seems not effective to lead the committee with more old member of the organization.

    Washington Irving's "Rip Van Winkle" has been so ritualistically cited and discussed by historians,political scientists and literary scholars that it is no longer just a simple tale but a prominent text in American culture.The tale,as one critic proclaims,"presides over the birth of the American imagination" (Fiedler xx).This essay revisits "Rip Van Winkle" for the sole purpose of considering how this literary text can also stimulate critical thinking on the connection between fiction (or poetry) and history.

  8. Crisis and Leadership Style Relationship in Entrepreneurs

    2011-12-01

    Full Text Available Crises are inevitable features of today‟s businesses. As a result of pressures from the economic technological and social cultural environment brought by rapid change and the ongoing intense competition, it is not possible to think of a firm that is exempt from crisis. The instability in the economy and turbulent environments force the firms to seek more effective management styles. Hence, the crisis management becomes important. Historically the traits that a leader should have a for a better management of crisis were investigated and theories were set forth thereupon. One of the theories related to the topic is thesituational leadership theory which was built by Fiedler in 1970. Fiedler found that the task oriented leaders were more successful under unfavorable conditions. In this study which is carried out to see whether there is a difference between task-oriented and relationship oriented leaders in terms of their perceptions regarding the crisis, it was found that the task-oriented leaders have a more positive perception of crisis. No significant difference between taskorientated and relationship orientated managers was found regarding the interaction of the firm with its environment and attitudes and behaviors of top management. Factor analysis and t tests were used to reach these results

    Measures of network topology and connectivity aid the understanding of network breakdown as the brain degenerates in Alzheimer's disease (AD). We analyzed 3-Tesla diffusion-weighted images from 202 patients scanned by the Alzheimer's Disease Neuroimaging Initiative – 50 healthy controls, 72 with early- and 38 with late-stage mild cognitive impairment (eMCI/lMCI) and 42 with AD. Using whole-brain tractography, we reconstructed structural connectivity networks representing connections between pairs of cortical regions. We examined, for the first time in this context, the network's Laplacian matrix and its Fiedler value, describing the network's algebraic connectivity, and the Fiedler vector, used to partition a graph. We assessed algebraic connectivity and four additional supporting metrics, revealing a decrease in network robustness and increasing disarray among nodes as dementia progressed. Network components became more disconnected and segregated, and their modularity increased. These measures are sensitive to diagnostic group differences, and may help understand the complex changes in AD. PMID:26640830

    Full Text Available Introduction: Stuttering is not a problem of individuals, but it’s a problem in the verbal communication with others. Individual and group treatment is equally important to use while working with people who stutter.Purpose: Group treatment is used to allow the patient adequate adjustment in all problematic situations (situations increasing stuttering in the environment and to gradually inhibit negative emotions.Material and methods: Objective speech tool is used in this testing (evaluation of speech status under Fiedler, PA Standop, R.Stotern-Schwarzenberg, Munchen, 1978 to determine the degree and type of speech disorder. The anxiety feeling is also evaluated, where the subjective assessment of patients' anxiety is expressed in units SUD (subjective units of disturbance or distress - subjective assessment of suffering.Results and Conclusion: The results showed that group stationary treatment has a huge significance in reducing the anxiety of patients who stutter.

  11. Contingency inferences driven by base rates: Valid by sampling

    Directory of Open Access Journals (Sweden)

    Florian Kutzner

    2011-04-01

    Full Text Available Fiedler et al. (2009, reviewed evidence for the utilization of a contingency inference strategy termed pseudocontingencies (PCs. In PCs, the more frequent levels (and, by implication, the less frequent levels are assumed to be associated. PCs have been obtained using a wide range of task settings and dependent measures. Yet, the readiness with which decision makers rely on PCs is poorly understood. A computer simulation explored two potential sources of subjective validity of PCs. First, PCs are shown to perform above chance level when the task is to infer the sign of moderate to strong population contingencies from a sample of observations. Second, contingency inferences based on PCs and inferences based on cell frequencies are shown to partially agree across samples. Intriguingly, this criterion and convergent validity are by-products of random sampling error, highlighting the inductive nature of contingency inferences.

    2014-12-01

    Full Text Available This paper describes way how to use graph theory in security analysis. As an environment is used network of power lines and devices which are included here. Power grid is considered as a system of nodes which make together graph (network. On the simple example is applied Fiedler´s theory which is able to select the most important power lines of whole network. Components related to these lines are logicly ordered and considered by author´s modified analysis. This method has been improved and optimalized for risks related with illegal acts. Each power grid component has been connected with possible kind of attack and every of this device was gradually evaluated by five coefficients which takes values from 1 to 10. On the coefficient basis was assessed the level of risk. In the last phase the most risky power grid components have been selected. On the selected devices have been proposed security measures.

  13. BASIC ACTUAL AND EFFECTIVENESS OF LEADERSHIP STYLES OF CONSTRUCTION PROJECT MANAGERS IN SURABAYA

    2004-01-01

    Full Text Available Leading is one of the most important facets in managing construction projects, and behaving as an effective leader is a vital project manager’s responsibility to ensure that work efforts of other persons are directed toward the accomplishment of organizational objectives. This paper aims to determine basic and actual leadership styles of construction project managers in Surabaya. The effectiveness of the actual leadership style is also examined. To accomplish the objective, the paper first briefly reviews the ways in which leadership is approached. Data were then collected through an empirical survey to 46 project managers, taking Fiedler and Hersey-Blanchard’s models as the point of departure. The results indicate that the basic leadership of project managers in Surabaya falls slightly on task-oriented behavior. Meanwhile selling is the most common style used as actual leadership in practice. The paper discusses the effectiveness of the styles adopted and situational variables affecting.

  15. Universities' expectations of pastoral care: trends, stressors, resource gaps and support needs for teaching staff.

    Science.gov (United States)

    Laws, Thomas A; Fiedler, Brenton A

    2012-10-01

    Since the mid-90s, the university environment has challenged the motivation of academic staff to engage in pastoral care. A literature review revealed five themes that aligned with analysis of interview data from a previous study (Laws and Fiedler, 2010). The key themes were i) staff were often disturbed by unplanned intrusions of students who exhibited behavioural problems or sought emotional support, ii) the management of emotions in face-to-face encounters was stressful, iii) staff felt under-equipped for dealing with Mental Health (MH) issues, iv) standards and control needed updating and v) counselling and disability services did not meet academics' need to know about 'at risk' students. Having identified the incidence of mental health issues among Australian University students, this study aims to locate literature that describes how well current university policies/protocols are supported by Evidence Based Practice in the management of MH problems in the student population. Findings from a content analysis of the literature were triangulated with verbatim comments recorded during a previous study that utilised semi structured interviews with 34 academics at the School of Nursing and Midwifery and the School of Commerce at the University of South Australia (Laws and Fiedler, 2010). Lack of clarity on role boundaries around promotion of students' well-being was not clearly defined. The Higher Education (HE) institutions' slowness in responding to mental health needs of students combined with the increasing expectations of academics' performance monitoring has lead staff to avoid deep investment in their students' well-being. The literature indicates that students are in need of psychological support, but pastoral care remains ill-defined despite enduring expectations held by university administrators. Teacher motivation is diminished by time spent with students in need of emotional support which is not acknowledged in workloads. Staff stress is increased by

  16. Double- and triple-differential cross sections for electron-impact ionization of helium

    International Nuclear Information System (INIS)

    Biswas, R.; Sinha, C.

    1995-01-01

    Triple- (TDCS) and double- (DDCS) differential cross sections have been calculated for single ionization in electron-helium collisions for asymmetric geometry at intermediate and medium high energies. The TDCS and DDCS results have been presented for different kinematical situations and have been compared with the corresponding experiments. In the present prescription, the final-state wave function involves the correlation between the two continuum electrons and satisfies the three-body asymptotic boundary condition (for asymmetric geometry), which is an important criterion for reliable ionization cross sections. The sensitivity of the ionization cross sections (particularly of the TDCS) with respect to the choice of the bound-state wave function of the He atom has also been studied, using two different forms of wave function of the He atom. The binary-to-recoil peak intensity ratio against momentum transfer in TDCS is found to be in closer agreement with the experiment for the simple Hylleraas wave function than for the Hartree-Fock wave function. The DDCS results are found to be in good agreement with the experimental data of Mueller-Fiedler et al. [J. Phys. B 19, 1211 (1986)] for lower ejected energy (E 2 ), while for higher E 2 the results are closer to the measurements of Shyn et al. [Phys. Rev. A 19, 557 (1979)] and Avaldi et al.

    Full Text Available The basic purpose of this paper is to point out and theoretically illuminate the key moments of transformation and re-constitution of the art theory during the first half of XIX century, taking as its point of departure the role and influence of Organicism as a philosophico-reflexive basis, gnoseological postulate and methodological pattern. Sedlmayr's attempt at foundation of a comparative morphology of architectural styles, taking into account the three constitutive building elements as analytical tools of study of concrete-historical manifestations of style: material structure (building materials, technique and intended usability, is a matter of particular attention of the following analysis. Regarding Viollet-le-Duc, the stress is on the interpretation of his conception of architectural form as the application of logically founded general laws of statics and construction, with a special emphasis on his thesis of logical and purposely-rational correspondence of the outer form and the functional structure of the interior. Finally, an attempt is made at the clarification of the revival of Viollet-le-Duc's explanatory pattern within the dynamic and subjectivistic conceptual transformations of form in Fiedler's, von Hildebrandt's and Focillon's theoretical conceptions.

    Full Text Available The background of this research is based on the structure of a company as resource of structural stagnancy on its managerial level. Otherwise, the company structure has to face organizational multidimensional competition in global market. Stagnancy became a problem to an organization if there would be some consequences of working and synergy decreased significantly. The resolution of such stagnancy, especially to those agencies that had good and successful track record, like a manager, can be logically a job rotation. In this case, a manager as an asset of management resource plays an important and strategic position in order to develop a competitive organization in global market nowadays. This research mainly aims to modify the management resources as one of a business strategy to gain successfulness of a company sustainably. This study took quantitative, interpretative, and descriptive approach. The findings of this study indicated that a periodic change in such away like a rotation on the level of managerial collaborative participation which adjusted to the Theory of Contingency by Fiedler can be done in organization system. Besides, it can be held on the level of managers to adapt themselves throughout the global market competition.

    In investigations of laminar or turbulent flows, wall shear is often important. Nevertheless, conventional particle image velocimetry (PIV) is difficult in near-wall regions. A near-wall measurement technique, named interfacial PIV (IPIV) [Nguyen, C., Nguyen, T., Wells, J., Nakayama, A., 2008. Proposals for PIV of near-wall flow over curved boundaries. In: Proceedings of 14th International Symposium on Applications of Laser Technique to Fluid Mechanics], handles curved boundaries by means of conformal transformation, directly measures the wall gradient, and yields the near-wall tangential velocity profile at one-pixel resolution. In this paper, we show the feasibility of extending IPIV to measure wall gradients by stereo reconstruction. First, we perform a test on synthetic images generated from a direct numerical simulation (DNS) snapshot of turbulent flow over sinusoidal bed. Comparative assessment of wall gradients derived by IPIV, stereo-IPIV and particle image distortion (PID) [Huang, H.T., Fiedler, H.E., Wang, J.J., 1993. Limitation and improvement of PIV. Experiments in Fluids 15(4), 263-273] is evaluated with DNS data. Also, the sensitivity of IPIV and stereo-IPIV results to the uncertainty of identified wall position is examined. As a practical application of IPIV and stereo-IPIV to experimental images, results from turbulent open channel flow over a backward-facing step are discussed in detail.

    Full Text Available En el siglo XIX, autores fundacionales del formalismo, como Fiedler o Hildebrand, contrapusieron estrictamente las artes plásticas, «puramente visuales», a las artes verbales del discurso, proscribiéndoles la narración y disociándolas de la temporalidad: se trata del «principio de exclusión del tiempo», vinculado al formalismo. Más tarde, el crítico «modernista» de arte Clement Greenberg planteó la instantaneidad, en tanto que opuesta a la duración, como modalidad ideal de la experiencia artística. Pero el historiador y crítico de arte Michael Fried, en sus textos de los años 60 sobre arte abstracto, se distancia de Greenberg, desarrollando un discurso sobre la temporalidad en las artes plásticas, con nociones como «tiempo visual»; y en sus posteriores textos historiográficos investiga las modalidades temporales de la representación pictórica. La aparente paradoja entre la crítica de Fried a la hipóstasis «literalista» de la duración en las tardovanguardias y el papel crucial que concede a Manet y a la instantaneidad en el origen del arte moderno, la resolveremos atendiendo a su reivindicación de la temporalidad durativa de «lo cotidiano». Así cabe comprender la concepción de la modalidad temporal característica de la modernidad y del arte moderno, a la que apunta su noción teórica de presentness.In the nineteenth century, seminal authors of Formalism, like Fiedler or Hildebrand, strictly compared the «purely visual» plastic arts to the discursive arts of verbal language, ruling out narrativity from plastic arts, which they dissociated from temporality - the formalist «principle of exclusion of time».

Art critic and historian Michael Fried did not share Greenberg's position, but developed instead a discourse about time in plastic arts. In his early

    [1] This study presents the first climatology for the dust emission amount associated with Nocturnal Low-Level Jets (NLLJs) in North Africa. These wind speed maxima near the top of the nocturnal boundary layer can generate near-surface peak winds due to shear-driven turbulence in the course of the night and the NLLJ breakdown during the following morning. The associated increase in the near-surface wind speed is a driver for mineral dust emission. A new detection algorithm for NLLJs is presented and used for a statistical assessment of NLLJs in 32 years of ERA-Interim reanalysis from the European Centre for Medium-Range Weather Forecasts. NLLJs occur in 29% of the nights in the annual and spatial mean. The NLLJ climatology shows a distinct annual cycle with marked regional differences. Maxima of up to 80% NLLJ frequency are found where low-level baroclinicity and orographic channels cause favorable conditions, e.g., over the Bodélé Depression, Chad, for November-February and along the West Saharan and Mauritanian coast for April-September. Downward mixing of NLLJ momentum to the surface causes 15% of mineral dust emission in the annual and spatial mean and can be associated with up to 60% of the total dust amount in specific areas, e.g., the Bodélé Depression and south of the Hoggar-Tibesti Channel. The sharp diurnal cycle underlines the importance of using wind speed information with high temporal resolution as driving fields for dust emission models. Citation: Fiedler, S., K. Schepanski, B.

    measures (e.g., Fiedler number, Kirchoff index) extracted from these matrices are shown to be sensitive to evolving nano-surface morphology. For instance, we observed that prominent nanoscale morphological changes on CMP processed Cu wafers, although discernible visually, could not be tractably quantified using statistical metrology parameters, such as arithmetic average roughness (Sa), root mean square roughness (Sq), etc. In contrast, CMP induced nanoscale surface variations were captured on invoking graph theoretic topological invariants. Consequently, the graph theoretic approach can enable timely, non-contact, and in situ metrology of semiconductor wafers by obviating the need for reticent profile mapping techniques (e.g., AFM, SEM, etc.), and thereby prevent the propagation of yield losses over long production runs.

    State-of-the-art climate models have persistently shown a spread in estimates of the effective radiative forcing (ERF) associated with anthropogenic aerosol. Different reasons for the spread are known, but their relative importance is poorly understood. In this presentation we investigate the role of natural atmospheric variability, global patterns of aerosol radiative effects, and magnitudes of aerosol-cloud interaction in controlling the ERF of anthropogenic aerosol (Fiedler et al., 2017). We use the Earth system model MPI-ESM1.2 for conducting ensembles of atmosphere-only simulations and calculate the shortwave ERF of anthropogenic aerosol at the top of the atmosphere. The radiative effects are induced with the new parameterisation MACv2-SP (Stevens et al., 2017) that prescribes observationally constrained anthropogenic aerosol optical properties and an associated Twomey effect. Firstly, we compare the ERF of global patterns of anthropogenic aerosol from the mid-1970s and today. Our results suggest that such a substantial pattern difference has a negligible impact on the global mean ERF, when the natural variability of the atmosphere is considered. The clouds herein efficiently mask the clear-sky contributions to the forcing and reduce the detectability of significant anthropogenic aerosol radiative effects in all-sky conditions. Secondly, we strengthen the forcing magnitude through increasing the effect of aerosol-cloud interaction by prescribing an enhanced Twomey effect. In that case, the different spatial pattern of aerosol radiative effects from the mid-1970s and today causes a moderate change (15%) in the ERF of anthropogenic aerosol in our model. This finding lets us speculate that models with strong aerosol-cloud interactions would show a stronger ERF change with anthropogenic aerosol patterns. Testing whether the anthropogenic aerosol radiative forcing is model-dependent under prescribed aerosol conditions is currently ongoing work using MACv2-SP in

    each introduction to appear as a short paper in the front of each one of the sessions, so that it can be cited as a regular paper. The Proceedings start with the Honour Speaker Talk by James Nichols (Nichols, 2004. This talk is traditionally the last one in the Conference, but we think that it nicely summarises how and why capture-recapture has developed to its current healthy state. The talk is in fact a tribute to David Anderson, to whom, as Nichols says, all of us are more or less in debt. Hence, we have preferred to move the Honour Talk to the front position of the Proceedings, and we would like this to be our humble tribute to David. At the end of the Proceedings appear a few papers which were presented in poster format, and a paper summarising several of the main topics presented at the traditional short course on capture-recapture, this time organized by the unflagging Evan Cooch. We would like to thank all the people who helped in one way or another to the successful completion of the EURING Conference and the Proceedings. We thank to the Session Chairs, their dedication and enthusiasm in organizing the sessions and also in editing the different papers. All their names appear in the front page of the Proceedings as credits. We thank Wolfgang Fiedler for the local organization of the event: a very difficult and exhausting task that is not always properly recognized. Jean Clobert, although unfortunately unable to attend the Conference, supported us with ideas and friendship meanwhile preparing the scientific program. Evan Cooch maintained the always successful web page (which probably will also become a classic in EURING conferences…, and organized the traditional course on capture-recapture. Charles Francis very efficiently organized the poster session and acted as editor for the papers sent for publication. Finally we thank the Ministerio de Ciencia y Tecnología for financial support to the publication of this special issue of Animal Biodiversity and

    by Homburg and Sandstede [24], Shilnikov et al. [43] and Fiedler [18]. The occurrence of T-points in local bifurcations has been discussed by Barrientos et al. [4], and by Lamb et al. [32] in the context of reversible systems. All these studies consider dynamics in R3 using a geometric return map approach, and their results reflect the description of types of nonwandering dynamics described above.Further related studies concerning T-points can be found in [34] and [37], where inclination flips were considered in this context. In [5], numerical studies of T-points are performed using kneading invariants.The main aim of this paper is to present a comprehensive study of dynamics near T-points, including detailed proofs of all results, employing a unified functional-analytic approach, without making any assumption on the dimension of the phase space. In the process, we recover and generalise to higher dimensional settings all previously reported results for T-points in R3. In addition, we reveal the existence of richer dynamics in the (RC) and (CC) cases. A detailed discussion of our results is contained in Section 2.The functional analytic approach we follow is commonly referred to as Lin's method, after the seminal paper by Lin [33], and employs a reduction on an appropriate Banach space of piecewise continuous functions approximating the initial heteroclinic cycle to yield bifurcation equations whose solutions represent orbits of the nonwandering set. The development of such an approach is typical for the school of Hale, and is in contrast to the analysis contained in previous T-point studies, which relies on the construction of a first return map. Our choice of analytical framework is motivated by the fact that Lin's method provides a unified approach to study global bifurcations in arbitrary dimension, and has been shown to extend to a larger class of settings, such as delay and advance-delay equations [19,33].

    Full Text Available According to the research of the last decade, there has been growth in the noncoronary disease infarction, increased their share among the causes temporary or persistent disability, disability and deaths. Among others myocarditis, which constitute 11% of all diseases of the cardiovascular system and is responsible for almost 20% of cases of sudden death in people physically safe. The disease is an inflammatory damage to cardiomyocytes, which is caused by direct action or indirectly through immune mechanisms of infectious agents of bacterial, viral, protozoan nature, as well as chemical and physical factors. The term "myocarditis" was first proposed I F Soberheim in 1837 and in 1900. A. Fiedler described the myocardial injury and justified the very concept of primary myocarditis. It is widely accepted that myocarditis - natural complications of infectious diseases in which etiological factor may be any infectious agent. However, at the present stage bacterial pathogens give way to viral. Those viruses according to numerous studies result in the development of myocarditis and consequently lead to the development of myocardial dysfunction. Until recently, most were considered cardiotropic ECHO viruses, Coxsackie group A, B, causing half of all cases of viral myocarditis. However recently reviewed the role of enteroviruses in favor of persistent virus and particularly the family Herpesviridae. The significance in the etiology of myocarditis herpes simplex virus, human herpes type 6, Epstein - Barr virus, cytomegalovirus. Published data indicate that the development of viral myocarditis patients after serous meningoencephalitis caused by the varicella-zoster virus. Widespread herpesvirus diseases their tropism for endothelial cells and myocardium, the capacity for long-term persistence in the body the opportunity to explain virus inducted inflammatory damage to cardiomyocytes. Increased attention to this issue recently linked with the present stage
