Norwegian retroflexion : licensing by cue or prosody?
A common topic in recent literature on phonology is the question of whether phonological processes and segments are licensed by prosodic position or by perceptual cues. The former is the traditional view, as represented by e.g. Lombardi (1995) and Beckman (1998), and holds that segments occur in specific prosodic positions such as the coda. In a licensing by cue approach, as represented by Steriade (1995, 1999), on the other hand, segments are assumed to occur in those positions only where their perceptual cues are prominent, independent of the prosodic position. In positions where the cues are not salient, neutralization occurs
Retroflexion and retraction revised
Arguing against Bhatâs (1974) claim that retroflexion cannot be correlated with retraction, the present article illustrates that retroflexes are always retracted, though retraction is not claimed to be a sufficient criterion for retroflexion. The cooccurrence of retraction with retroflexion is shown to make two further implications; first, that non-velarized retroflexes do not exist, and second, that secondary palatalization of retroflexes is phonetically impossible. The process of palatalization is shown to trigger a change in the primary place of articulation to non-retroflex. Phonologically, retraction has to be represented by the feature specification [+back] for all retroflex segments
Variation in the perception of an L2 contrast : a combined phonetic and phonological account
The present study argues that variation across listeners in the perception of a non-native contrast is due to two factors: the listener-specic weighting of auditory dimensions and the listener-specic construction of new segmental representations. The interaction of both factors is shown to take place in the perception grammar, which can be modelled within an OT framework. These points are illustrated with the acquisition of the Dutch three-member labiodental contrast [V v f] by German learners of Dutch, focussing on four types of learners from the perception study by Hamann and Sennema (2005a)
Dynamical Screening Effects in Correlated Electron Materials -- A Progress Report on Combined Many-Body Perturbation and Dynamical Mean Field Theory: "GW+DMFT"
We give a summary of recent progress in the field of electronic structure
calculations for materials with strong electronic Coulomb correlations. The
discussion focuses on developments beyond the by now well established
combination of density functional and dynamical mean field theory dubbed
"LDA+DMFT". It is organized around the description of dynamical screening
effects in the solid. Indeed, screening in the solid gives rise to dynamical
local Coulomb interactions U(w) (Aryasetiawan et al 2004 Phys. Rev. B 70
195104), and this frequency-dependence leads to effects that cannot be
neglected in a truly first principles description. We review the recently
introduced extension of LDA+DMFT to dynamical local Coulomb interactions
"LDA+U(w)+DMFT" (Casula et al. Phys. Rev. B 85 035115 (2012), Werner et al.
Nature Phys. 8 331 (2012)). A reliable description of dynamical screening
effects is also a central ingredient of the "GW+DMFT" scheme (Biermann et al.
Phys. Rev. Lett. 90 086402 (2003)), a combination of many-body perturbation
theory in Hedin's GW approximation and dynamical mean field theory. Recently,
the first GW+DMFT calculations including dynamical screening effects for real
materials have been achieved, with applications to SrVO3 (Tomczak et al.
Europhys. Lett. 100 67001 (2012); Phys. Rev. B 90 165138 (2014)) and adatom
systems on surfaces (Hansmann et al. Phys. Rev. Lett. 110 166401 (2013)). We
review these and comment on further perspectives in the field. This review is
an attempt to put elements of the original works (Refs. 1-11) into the broad
perspective of the development of truly first principles techniques for
correlated electron materials.Comment: 40 pages, 12 figures. First published as "Highlight of the Month"

On the necessity of wonder: how to explain an artwork to a committee
This essay emerged from an exhibition in 2006 in which notions of the Wunderkammer became central in the curation of the show. It brought together work by Anna Boggon, Silke Dettmers and Helen Maurer, three artists employing the language of what one could call the 'contemporary surreal' ('The Wrong End of the Telescope', Three Colts Gallery, London). The history and concept of the Wunderkammer is critical for the argument pursued in this article, which calls for the re-instatement of 'wonder' and the idea of 'the marvellous'. These are vital ingredients for visual arts practice but are unacknowledged in today's art academies. It takes on board the current debate of 'visual arts practice as research' and extends the argument of authors such as Sullivan (Art Practice as Research, 2005) and Barone, by demonstrating conventional academic definitions of 'knowledge' and artistic practice to be irreconcilable. The importance of not knowing. Wunderkammern and Curiosity Cabinets. Some thoughts on the real, the surreal and the contemporary surreal. The aspirations of words and the difficulties with 'proof'. Heterotopias. Questions rather than answers
Yakuza Past, Present and Future: The Changing Face of Japan\u27s Organized Crime Syndicates
While Japanese crime syndicates are deeply entrenched in the history and culture of Japan, much of what is known in the Western world about the Yakuza is primarily the result of stereotyping generated by media-driven sensationalism and lowbudget motion pictures. Judgment on the crime syndicates\u27 continued existence, modes of operation, and relatively high visibility in Japan is oftentimes passed based on socio-cultural perceptions of deviance that differ from those in Japanese culture. Taking the form of a book review essay, this paper aims to re-introduce the reader to Japan\u27s crime syndicates with the goal of replacing stereotypes and myths with factual information. Utilizing two seminal works written by authorities of the field, the paper chronicles the history of the Yakuza\u27s origins and evolution, outlines their organizational structures, describes the groups\u27 past and current operations, and provides a brief overview of the crime syndicates\u27 likely future
German glide formation functionally viewed
Glide formation, a process whereby an underlying high front vowel is realized as a palatal glide, is shown to occur only in unstressed prevocalic position in German, and to be blocked by specific surface restrictions such as *ji and *âj. Traditional descriptions of glide formation (including derivational as well as Optimality theoretic approaches) refer to the syllable in order to capture its conditions. The present study illustrates that glide formation (plus the distribution of long and short tense /i/) in German can better be captured in a Functional Phonology account (Boersma 1998) which makes reference to stress instead of the syllable and thus overcomes problems of former approaches
