Neoliberalism: Befall or Respite?
No full textThe authors of this argumentative article emphasize that the range of the current crisis cannot be depleted in the diagnosis which is based on cyclic consideration. It is both systematic and structural, which is derived from the genesis and the modus of neoliberalism, which has become dominant during the previous decades. Other than that, it is emphasized that the current crisis is “great”, because it forces relevant actors to face the structural characteristics of contemporary shareholder-capitalism. The crisis also puts to a test the self-reflection of the economic science which faces certain deficits. The authors believe that, given the tendencies in today’s economy, there can be different scenarios for exiting the crisis and projecting a new modus of capitalism in the following period. Having in mind the openness of the present and the uncertainty of the future, the authors describe those scenarios without projecting which one of them will be dominant.Capitalism, Crisis, Neoliberalism, Cyclic, System, Structure
Treatment of partial-thickness burns with a tulle-gras dressing and a hydrophilic polyurethane membrane: a comparative study
No full textObjective: The purpose of this revisited study was to compare the clinical efficacy and long-term scar evaluation of a hydrophilic polyurethane membrane (HPM), Omiderm (Omikron Scientific Ltd., Rehovot, Israel) and an antimicrobial tulle-gras dressing (TGD), Bactigras (Smith & Nephew) in the management of partial-thickness burns. Method: Patients with partial-thickness burns were enrolled in this prospective study. Burn areas were divided into two areas and both dressings were applied to each field at the same time. Time to full re-epithelialisation and scar evaluation were compared using the Vancouver Scar Scale (VSS). Results: A total of 21 patients, mean age 36.8 years, with 22 burns areas participated. The results showed that there is no statistically significant difference in terms of full epithelialisation time in the application of either dressing (p>0.05). However, with deep dermal burns, the HPM provided slightly faster epithelialisation (p>0.05). A VSS assessment showed no statistically significant difference (p>0.05) between applying either dressing materials. Conclusion: This study indicated that both dressings had the same effectiveness in treatment of partial-thickness burn wounds. However, the use of the HPM, especially in deep dermal second-degree burns, should be one of the first-line clinical choices, based on the advantages discerned by this study
Postglitch relaxation of the Crab pulsar after its first four major glitches: The combined effects of crust cracking, formation of vortex depletion region and vortex creep
No full textFollowing the application of vortex creep theory (Alpar et al. 1984; Alpar et al. 1993; Chau et al. 1993) to the postglitch behavior of the Vela pulsar, we extend the model to cover the postglitch behavior of the Crab pulsar (Alpar et al. 1994). We propose that the comparatively modest (ΔΩ/Ω ∼ 10 -8) and somewhat infrequent (∼6 yr interglitch intervals) Crab pulsar glitches are caused by crust cracking during starquakes induced by pulsar spin-down (Ruderman 1976; Baym & Pines 1971). We attribute the anomalous postglitch behavior (an occasional extended spin-up and a long-term response opposite in sign to that seen in the Vela pulsar [see Lyne, Graham-Smith, & Pritchard 1992]) to postglitch response to inward vortex bunching into newly formed vortex traps during a quake. The persistent shift in the angular acceleration Ω c following a glitch is attributed to the creation of a new vortex depletion region (Alpar & Pines 1993). The different postglitch behavior for the Crab and Vela pulsars can be understood on evolutionary grounds (Alpar et al. 1994). © 1996. The American Astronomical Society.

Postglitch relaxation of the Crab pulsar: Evidence for crust cracking
No full textThe pattern of glitches and postglitch behavior observed for the Crab pulsar (Boynton et al. 1972; Demiański & Prószyński 1983; Lyne & Pritchard 1987; Lyne, Graham-Smith, & Pritchard 1992) is strikingly different from that observed for the Vela pulsar (Alpar et al. 1993). A key question is whether the differences can be understood on evolutionary grounds. An analysis of the Crab pulsar suggests that this is indeed the case. Thus, we propose that the comparatively modest (ΔΩ/Ω ∼ 10 -8) and somewhat infrequent (∼6 yr interglitch intervals) Crab pulsar glitches are caused by starquakes induced by pulsar spin-down (Ruderman 1976; Baym & Pines 1971); we attribute its anomalous postglitch behavior (an occasional extended spin-up and a long-term response opposite in sign to that seen in the Vela pulsar (Lyne et al. 1992) to vortices transported inward during a quake, while the observed unexpected persistent change in angular acceleration, Ω̇ e, following a glitch represents the creation of a new vortex depletion region, as suggested by Alpar & Pines (1993).link_to_subscribed_fulltex
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
The Alpar canyon system in the Pannonian Basin, Hungary – its morphology, infill and development
No full textGiant incised canyons were recently recognized in Late-Miocene post-rift sediments in the central part of the Pannonian Basin. Though not connected to the world seas, Lake Pannon shows significant signs of relative lake level variations controlled by tectonics and climate changes. The incision surface of the Alpar canyon system is connected to SB Pa-4 (6.8 Ma sensu Vakarcs, 1997), earlier reported to represent a significant relative base-level fall in the basin, however, debated recently.
Incised several hundred meters in the preexisting substrate, the individual canyon valleys of the Alpar canyon system are enormous in size and display a multi-story nature. They loose topographic expression headwards and basinward. Widths of individual valleys range from 5 to 10 km, with smaller tributaries. In the study area several adjacent canyon valleys can be seen on seismic profiles. The valley depth is greatest near their confluence, where a major trunk valley (600–700 m deep) was formed by eroding most of the Upper Miocene succession. The canyons are filled with clay marls. They are incised into an extremely thick aggrading deltaic complex and are overlain by fluvial sediments, suggesting a major transgression in between.
The Late Miocene Alpár canyon system developed on the southern margin of the Mid-Hungarian Mobile Belt, the latter is characterized by NE-SW oriented fold axis and NE-SW oriented left lateral strike-slip faults. The canyon system coincides with a large releasing bend and/or extensional duplex of the Paks–Szolnok strike-slip system being active as sinistral during the Late Miocene.
Presumably, the formation of the deep canyons was generated by the close interaction of several factors and events in space and time, among them tectonic uplift forced relative base-level fall, the reactivation and bending/duplexing of a strike-slip fault system located near the coeval zone of the lake shoreline and shelf edge, and the possible change of sediment supply carried by overfed rivers
Modelling of quasi-periodic oscillations with wave packets
No full textModel dispersion relations are introduced to explore power spectra of the normal-branch (NB) and horizontal-branch (HB) quasi-periodic oscillations (QPOs; for reviews see Van der Klis (1989)[ARA&A, 27, 517], (1992) [Proc. of NATO ASI X-Ray Binaries and Recycled Pulsars, eds. E.P.J. Van den Heuvel & S.A. Rappaport, Kluwer, Dordrecht], (1995)[Proc, of NATO ASI The Lives of the Neutron Stars, eds. M.A. Alpar, Omit Kiziloglu, & J. van Paradijs, Kluwer, Dordrecht]) of low mass X-ray binaries (LMXBs) in terms of wave packets and to illustrate the presence of frequency bands around the Kepler and beat frequencies. For the NE QPOs wave packets of sound waves in a thick middle disk state, with frequencies determined by the rotation frequency, have wavelengths comparable to the size of the middle disk. For Z-sources on the HB, the wave packets result from disturbances in the inner disk induced by the neutron star magnetic field which rotates at the beat frequency with respect to the inner disk. For both the NE and the HB QPOs, we construct simple model dispersion relations, and show that the QPO peaks in the observed power spectra correspond to reasonable wavelengths and system parameters. The kilohertz QPOs, which were discovered after the original version of this paper was submitted, are also discussed as a possible realization of the Kepler and beat frequency bands. Problems of integrating the kHz and HB QPOs in a disk model are briefly noted. It is tentatively suggested that supersonic and wave propagation regions of the inner disk have complementary functions for the origin of kHz and HB QPOs respectively. (C) 1997 Elsevier Science B.V
Exploring Emptiness: An Investigation of MA and MU in My Sonic Composition Practice
No full textThe commentary investigates Japanese aesthetics of space, silence and emptiness - ma and mu - that informed my compositional practice during the research period 2012 - 2015. The portfolio comprises text compositions and sound installations in which forms of micro events and sustained events are employed. Throughout, the emphasis is on my personal engagement with, and manifestation of emptiness that concerns a particular model of listening and perception.
Chapter 1 discusses six primary research areas: ma and mu, material, text, form, listening and perception. Firstly, I introduce ma and mu by examining noh culture and Zeami's teaching of senu hima (where there is no-action) in the context of my personal approaches to music. The following subjects are then used to contextualise my PhD practice by means of examples from various composers and visual artists. Here, these particular and enigmatic concepts are explored through Japanese art as well as Western contemporary works by Alvin Lucier, Eliane Radigue and those of the Wandelweiser collective.
Part 2 provides contextual commentaries on selected compositions from the portfolio that mostly articulate my aesthetics in relation to the topics covered in Chapter 1. koso koso addresses my methodologies to investigate the essence of senu hima, followed by treow that discusses my approach to materials and the importance of space. I move on to grade two and grade two extended in order to examine text scores, and then, look into Espèces d'espaces 03 and 04 as examples of musical forms that I employ.
Finally, listening and perception are investigated through the compositions gnome and con.de.structuring. Throughout, I describe how my works explore emptiness as a result of my particular emphasis on listening over composing
The construction of Karen Karnak: The multi-author-function
No full textThis thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author
