„Lernen nicht, aber ...“ - Bildungsprozesse im Breaking

With over 30 years of tradition, breaking in Germany provides fascinating insights into the learning of dance in Hip Hop culture, reaching from informal street learning to the introduction of courses in educational institutions. This article draws information from a qualitative empirical study based on the Grounded Theory Methodology. The study asked subjects ranging from first-generation German B-Boys and B-Girls to teenage students about how they have learned and currently learn to break. The interview material reveals a rich and self-regulated learning culture with strong impact on protagonists. A synergy of social, aesthetic, and ethical principles seems to be characteristic, creating a gravitational field of learning with a unique and complex form of imitation at its core. (DIPF/Orig.)

Symmetry-breaking in chiral polymerisation

We propose a model for chiral polymerisation and investigate its symmetric and asymmetric solutions. The model has a source species which decays into left- and right-handed types of monomer, each of which can polymerise to form homochiral chains; these chains are susceptible to `poisoning' by the opposite handed monomer. Homochiral polymers are assumed to influence the proportion of each type of monomer formed from the precursor. We show that for certain parameter values a positive feedback mechanism makes the symmetric steady-state solution unstable. The kinetics of polymer formation are then analysed in the case where the system starts from zero concentrations of monomers and chains. We show that following a long induction time, extremely large concentrations of polymers are formed for a short time, during this time an asymmetry introduced into the system by a random external perturbation may be massively amplified. The system then approaches one of the steady-state solutions described above.

Breaking through the Margins: Pushing Sociopolitical Boundaries Through Historic Preservation

“Breaking through the Margins: Pushing Sociopolitical Boundaries Through Historic Preservation” explores the ways in which contemporary grassroots organizations are adapting historic preservation methods to protect African American heritage in communities that are on the brink of erasure. This project emerges from an eighteen-month longitudinal study of three African American preservation organizations—one in College Park, Maryland and two in Houston, Texas—where gentrification or suburban sprawl has all but decimated the physical landscape of their communities. Grassroots preservationists in Lakeland (College Park, Maryland), St. John Baptist Church (Missouri City, Texas), and Freedmen’s Town (Houston, Texas) are involved in pushing back against preservation practices that do not, or tend not, to take into consideration the narratives of African American communities. I argue, these organizations practice a form of preservation that provides immediate and lasting effects for communities hovering at the margins. This dissertation seeks to outline some of the major methodological approaches taken by Lakeland, St. John, and Freedmen’s Town. The preservation efforts put forth by the grassroots organizations in these communities faithfully work to remind us that history without preservation is lost. In taking on the critical work of pursuing social justice, these grassroots organizations are breaking through the margins of society using historic preservation as their medium.

Mapping chiral symmetry breaking in the excited baryon spectrum

We study the conjectured “insensitivity to chiral symmetry breaking” in the highly excited light baryon spectrum. While the experimental spectrum is being measured at JLab and CBELSA/TAPS, this insensitivity remains to be computed theoretically in detail. As the only existing option to have both confinement, highly excited states, and chiral symmetry, we adopt the truncated Coulomb-gauge formulation of QCD, considering a linearly confining Coulomb term. Adopting a systematic and numerically intensive variational treatment up to 12 harmonic oscillator shells we are able to access several angular and radial excitations. We compute both the excited spectra of I=1/2 and I=3/2 baryons, up to large spin J=13/2, and study in detail the proposed chiral multiplets. While the static-light and light-light spectra clearly show chiral symmetry restoration high in the spectrum, the realization of chiral symmetry is more complicated in the baryon spectrum than earlier expected.

Breaking Images, Widening Perceptions : Reflections on Horacio Quiroga in Translation

Horacio Quiroga (1878-1937) es uno de los escritores más logrados por sus cuentos y sigue siendo aclamado por la crítica en el mundo de habla hispana. Sus obras son consideradas parte del canon dentro de la tradición literaria sudamericana. Algunas de sus historias más renombradas circulan para la audiencia más global, publicadas en diversas colecciones y antologías que han sido posibles por haber sido traducidas al inglés. La versión más disponible en inglés es la traducción realizada por Margaret Sayers Peden ((1976) 2004), Quiroga habla por medio de las elecciones que realizó la traductora. Sin embargo, cabe preguntarse: ¿es este el Horacio Quiroga que las generaciones anteriores conocieron, apreciaron y alabaron? ¿Han logrado sobrevivir a la operación traductológica en inglés su prosa exquisita y su narrativa fotográfica para los lectores en inglés? Este artículo intenta abordar temas centrales de la traducción literaria en cuanto los textos de Quiroga y de Sayers Peden. También trata sobre las estrategias de domesticación, sobre cómo la manipulación del original puede traer consecuencias para la legibilidad, además la importancia de conocer bien los rasgos sociopolíticos y las características geográficas y, no menor, la responsabilidad profesional implícita en el rol del traductor como mediador cultural ya que selecciona, edita y publica literatura que no pertenece a lo convencional y establecido.

Breaking the curve with candels: a Bayesian approach to reveal the non-universality of the dust-attenuation law at high redshift

Dust attenuation affects nearly all observational aspects of galaxy evolution, yet very little is known about the form of the dust-attenuation law in the distant universe. Here, we model the spectral energy distributions of galaxies at z ~ 1.5–3 from CANDELS with rest-frame UV to near-IR imaging under different assumptions about the dust law, and compare the amount of inferred attenuated light with the observed infrared (IR) luminosities. Some individual galaxies show strong Bayesian evidence in preference of one dust law over another, and this preference agrees with their observed location on the plane of infrared excess (IRX, L_TIR/L_UV) and UV slope (β). We generalize the shape of the dust law with an empirical model, A_ λ,σ =E(B-V)k_ λ (λ / λ v)^ σ where k_λ is the dust law of Calzetti et al., and show that there exists a correlation between the color excess E(B-V) and tilt δ with δ =(0.62±0.05)log(E(B-V))+(0.26±0.02). Galaxies with high color excess have a shallower, starburst-like law, and those with low color excess have a steeper, SMC-like law. Surprisingly, the galaxies in our sample show no correlation between the shape of the dust law and stellar mass, star formation rate, or β. The change in the dust law with color excess is consistent with a model where attenuation is caused by scattering, a mixed star–dust geometry, and/or trends with stellar population age, metallicity, and dust grain size. This rest-frame UV-to-near-IR method shows potential to constrain the dust law at even higher redshifts (z>3).

Using multiple GPUs to accelerate string searching for digital forensic analysis

String searching within a large corpus of data is an important component of digital forensic (DF) analysis techniques such as file carving. The continuing increase in capacity of consumer storage devices requires corresponding im-provements to the performance of string searching techniques. As string search-ing is a trivially-parallelisable problem, GPGPU approaches are a natural fit – but previous studies have found that local storage presents an insurmountable performance bottleneck. We show that this need not be the case with modern hardware, and demonstrate substantial performance improvements from the use of single and multiple GPUs when searching for strings within a typical forensic disk image.

Breaking old and new ground: a comparative study of coastal and inland naming in Berwickshire

This thesis investigates the place-names of four parishes in Berwickshire and compares coastal and inland naming patterns. Berwickshire is a large county that borders on northern England and historically formed part of Anglo-Saxon Northumbria. Partly due to the survival of extensive archives from the medieval priory of Coldingham, preserved in Durham Cathedral Archives, this county holds some of Scotland’s earliest recorded place- names. The parishes that form the research area are grouped together in the north-east of the county. Two of these parishes, Abbey St Bathans and Bunkle & Preston, are inland, and two, Cockburnspath and Coldingham, have extensive coastlines. The diversity of this group of parishes allows a comparative study of the place-names of coastal and inland areas to be undertaken. The topography of Berwickshire’s thirty-two parishes is very varied, and the four parishes have been chosen to reflect this range of landscapes. The place-names within the four parishes examined in this thesis derive almost exclusively from Old English, Older Scots, Modern Scots including Standard Scottish English, with a small minority derived from Old Norse, Gaelic, and Brittonic. The chronology of Old English, Older Scots, and Modern Scots is defined as given in the Concise Scots Dictionary: Old English is the period up to 1100, Older Scots is the period 1100-1700, and Modern Scots is the period 1700 onwards (CSD, 1985: xiii). Often with place-names it is not possible to give a precise dating for the coining of a toponym. For the purposes of this study, the language label given for a toponym is that of the date of the earliest record of the place-name with earlier linguistic evidence supplementing discussion. This thesis focuses on the names of topographic features, for example hills, rocks and woodland, and the role of perception in their naming. In order to compare the role of perception in inland and coastal naming, this thesis includes a diachronic study of the toponymy of the research area, along with two case studies. The first of these is a study of the toponymy of relief features, which focuses on generic elements in order to compare the perception of one type of referent in the two environments. The second is a study of the ‘colour’ category, which focuses on qualifying elements in order to compare the use of colour terms in the two environments. This thesis is the first comparative study of inland and coastal place-names, and it is one of the first to investigate new ways of using fieldwork as a central part of its methodology. In doing so it proposes innovative and nuanced ways to understand the toponymy of diverse landscapes within a community.

Imaginar metáforas de amor, sexo e fé: uma leitura literária de Breaking the Waves (1996) de Lars von Trier

Either with words or images, the expression of feelings results, in a work of art, in communication. If this was not the case, the work would not require a spectator or a reader. And if words suggest images from what its author refers to and a countless number of figurations may happen, the images from a film reveal what you can see. We are often left with "just" the space for those facts to shape up as possible meanings to which we react with emotion or with a particular intellectualization, finding exactly what we call readings or interpretations. Starting from a definition of literature that we see spilled in the work prospected from the polysystem theory by Itamar Even-Zohar from the Porter Institute for Poetics and Semiotics (University of Tel-Aviv), we consider the dynamic character of every cultural moment/object. This is how a literary reading, that is to apply some of the methodologies in the interpretation of a literary work, is allowed to extend to other cultural objects. This is what we are going to do with Lars von Trier's Breaking the Waves, a landmark in cinema for what the movement and manifest Dogma 95 represents, but that for a literature reader particularly focused on the narration of love in its different manifestations - in which sex and faith are included - a corpus is revealed, filled with interpretative possibilities and emotional reactions, important condiments particularly to the spectator and/or interested reader.

Quark model with chiral-symmetry breaking and confinement in the Covariant Spectator Theory

We propose a model for the quark-antiquark interaction in Minkowski space using the Covariant Spectator Theory. We show that with an equal-weighted scalar-pseudoscalar structure for the confining part of our interaction kernel the axial-vector Ward-Takahashi identity is preserved and our model complies with the Adler-zero constraint for π-π-scattering imposed by chiral symmetry.
