Chopper: From the Inside: Discourses of the "Celebrity" Criminal Mark Read

Popular culture has been inundated with stories and images of True Crime for a long time, which is testament to people’s enduring fascination with criminals and their deviant actions. In such stories, which present actual cases of notorious crimes in a style that often resembles fiction, criminals are either reviled as monsters or lauded as cultural icons. More recently, popular autobiographical accounts by criminals themselves have begun to emerge within this True Crime genre. Typically self-celebratory in nature, such representations construct a rather glamorized public image of the author. This article undertakes a multimodal analysis of what has been classed as one typical example of this True Crime sub-genre, Australian Mark Brandon Read’s autobiographical account Chopper: From the Inside. It thereby seeks to demonstrate that the book, while glamorizing and mythologizing its protagonist, simultaneously offers scope for a qualitative understanding of Read’s life of crime and the sensual dynamics of his violent offending. To this end, the analysis focuses on some of the linguistic and pictorial strategies Read employs in constructing a public image of himself that alternates between the dangerous ‘hardman’ and the ‘larrikin’ criminal hero. However, it is also shown that Read’s account reveals a degree of critical self-reflection. In addition to the multimodal analysis, the article also endeavours to explore the link between celebrity and crime, thereby engaging with the nature of popular culture’s fascination with celebrated criminals.

A Human Rights Triumph? Dictatorship-Era Crimes and the Chilean Supreme Court

This article assesses the dramatic shift in Chilean Supreme Court jurisprudence toward accountability for crimes committed during the dictatorship and sets it within the context of judicial reform and political change. Chile's experience has been identified as emblematic of delayed justice, but an examination of key case law identifies the narrow scope and instability of Supreme Court decision-making. The Court has been uncharacteristically assertive in its application of human rights norms yet vulnerable to external influences. The Chilean example underscores the need for political leadership to address past violations in post-conflict societies. Political inertia impeded justice claims and, as a result, change required significant judicial innovation.

Normal type Ia supernovae from violent mergers of white dwarf binaries

One of the most important questions regarding the progenitor systems of Type Ia supernovae (SNe Ia) is whether mergers of two white dwarfs can lead to explosions that reproduce observations of normal events. Here we present a fully three-dimensional simulation of a violent merger of two carbon-oxygen white dwarfs with masses of 0.9 M and 1.1 M combining very high resolution and exact initial conditions. A well-tested combination of codes is used to study the system. We start with the dynamical inspiral phase and follow the subsequent thermonuclear explosion under the plausible assumption that a detonation forms in the process of merging. We then perform detailed nucleosynthesis calculations and radiative transfer simulations to predict synthetic observables from the homologously expanding supernova ejecta. We find that synthetic color light curves of our merger, which produces about 0.62 M of Ni, show good agreement with those observed for normal SNe Ia in all wave bands from U to K. Line velocities in synthetic spectra around maximum light also agree well with observations. We conclude that violent mergers of massive white dwarfs can closely resemble normal SNe Ia. Therefore, depending on the number of such massive systems available these mergers may contribute at least a small fraction to the observed population of normal SNe Ia. © 2012 The American Astronomical Society.

On the brightness distribution of type ia supernovae from violent white dwarf mergers

We investigate the brightness distribution expected for thermonuclear explosions that might result from the ignition of a detonation during the violent merger of white dwarf (WD) binaries. Violent WD mergers are a subclass of the canonical double degenerate scenario where two carbon-oxygen (CO) WDs merge when the larger WD fills its Roche lobe. Determining their brightness distribution is critical for evaluating whether such an explosion model could be responsible for a significant fraction of the observed population of Type Ia supernovae (SNe Ia). We argue that the brightness of an explosion realized via the violent merger model is mainly determined by the mass of Ni produced in the detonation of the primary COWD. To quantify this link, we use a set of sub-Chandrasekhar mass WD detonation models to derive a relationship between primary WD mass (m) and expected peak bolometric brightness (M). We use this m-M relationship to convert the masses of merging primary WDs from binary population models to a predicted distribution of explosion brightness. We also investigate the sensitivity of our results to assumptions about the conditions required to realize a detonation during violent mergers ofWDs. We find a striking similarity between the shape of our theoretical peak-magnitude distribution and that observed for SNe Ia: our model produces a M distribution that roughly covers the range and matches the shape of the one observed for SNe Ia. However, this agreement hinges on a particular phase of mass accretion during binary evolution: the primary WD gains ~0.15-0.35M? from a slightly evolved helium star companion. In our standard binary evolution model, such an accretion phase is predicted to occur for about 43 per cent of all binary systems that ultimately give rise to binary CO WD mergers. We also find that with high probability, violent WD mergers involving the most massive primaries (?1.3M?, which should produce bright SNe) have delay times ?500 Myr. © 2012 The Authors.
