The Definition of Slavery in International Law

On the basis of archival research, this Article considers the negotiation history of both the 1926 Slavery Convention and 1956 Supplementary Convention and demonstrates that an interpretation of the provisions of the definition of slavery consonant with the travaux préparatoires reveal a definition which provides for the possibility of holding States and individuals responsible for not only slavery de jure but also de facto. That understanding is premised on a reading of the definition that speaks not of the ‘ownership’ of one person by another; but of the powers attached to the right of ownership. It is through an exploration of this phrase that a proper understanding of the definition of slavery in international law emerges.

Building and testing age models for radiocarbon dates in Lateglacial and Early Holocene sediments

The growing importance of understanding past abrupt climate variability at a regional and global scale has led to the realisation that independent chronologies of past environmental change need to be compared between various archives. This has in turn led to attempts at significant improvements in the required precision at which records can be dated. Radiocarbon dating is still the most prominent method for dating organic material from terrestrial and marine archives, and as such many of the recent developments in improving precision have been aimed at this technique. These include: (1) selection of the most suitable datable fractions within a record, (2) the development of better calibration curves, and (3) more precise age modelling techniques. While much attention has been focussed oil the first two items, testing the possibilities of the relatively new age modelling approaches has not received much attention. Here, we test the potential for methods designed to significantly improve precision in radiocarbon-based age models, wiggle match dating and various forms of Bayesian analyses. We demonstrate that while all of the methods can perform very well, in some scenarios, caution must be taken when applying them. It appears that an integrated approach is required in real life dating situations where more than one model is applied, with strict error calculation, and with the integration of radiocarbon data with sedimentological analyses of site formation processes.

`No dream is ever just a dream': Stanley Kubrick's Eyes Wide Shut as monofilm

This article examines Stanley Kubrick's final film, Eyes Wide Shut (1999), in relation to its source text, J.M.Q. Davies's 1999 translation of Arthur Schnitzler's Traumnovelle/Dream Story, originally published in 1926. Both the film and the novel are viewed through the lens of monodrama, a dramatic genre characterized by the attempt to convey the subjective psychical experience of a strong central protagonist. Monodramatic traits may also be found in the novel and film, and the article explores how this adaptation typifies certain aspects of the monodrama form and how those traits are portrayed through the specific conventions and limitations of the differing media.

ARTICLE: Property and the Definition of Slavery

Currently there is no clear understanding of the meaning of ‘slavery’ in modern international law. While generally it is accepted that the
authoritative definition of slavery is provided by Article 1 of the Slavery Convention 1926, in recent times slavery has been understood in such a wide variety of ways that effectively it is a meaningless term. This paper reflects on this interpretation problem and aims to redress this balance by reclaiming the core meaning of the legal definition. It applies property law perspectives to explain the conception of ownership invoked by Article 1, to argue that it remains relevant and to explore how it might be applied in identifying modern cases of slavery.

Seeking to Understand the Definition of Slavery

Examines the concept of ownership invoked by Article 1 of the 1926 Slavery Convention. Argues the definition of slavery must be understood substantively, not formally, and that ideas of property and ownership continue to have important theoretical and practical relevance in identifying modern slavery.

Informational masking in young and elderly listeners for speech masked by simultaneous speech and noise

Three experiments measured the effects of age on informational masking of speech by competing speech. The experiments were designed to minimize the energetic contributions of the competing speech so that informational masking could be measured with no large corrections for energetic masking. Experiment 1 used a "speech-in-speech-in-noise" design, in which the competing speech was presented in noise at a signal-to-noise ratio (SNR) of -4 dB. This ensured that the noise primarily contributed the energetic masking but the competing speech contributed the informational masking. Equal amounts of informational masking (3 dB) were observed for young and elderly listeners, although less was found for hearing-impaired listeners. Experiment 2 tested a range of SNRs in this design and showed that informational masking increased with SNR up to about an SNR of -4 dB, but decreased thereafter. Experiment 3 further reduced the energetic contribution of the competing speech by filtering it into different frequency bands from the target speech. The elderly listeners again showed approximately the same amount of informational masking (4-5 dB), although some elderly listeners had particular difficulty understanding these stimuli in any condition. On the whole, these results suggest that young and elderly listeners were equally susceptible to informational masking. © 2009 Acoustical Society of America.

Encouraging children to think counterfactually enhances blocking in a causal learning task

According to a higher order reasoning account, inferential reasoning processes underpin the widely observed cue competition effect of blocking in causal learning. The inference required for blocking has been described as modus tollens (if p then q, not q therefore not p). Young children are known to have difficulties with this type of inference, but research with adults suggests that this inference is easier if participants think counterfactually. In this study, 100 children (51 five-year-olds and 49 six- to seven-year-olds) were assigned to two types of pretraining groups. The counterfactual group observed demonstrations of cues paired with outcomes and answered questions about what the outcome would have been if the causal status of cues had been different, whereas the factual group answered factual questions about the same demonstrations. Children then completed a causal learning task. Counterfactual pretraining enhanced levels of blocking as well as modus tollens reasoning but only for the younger children. These findings provide new evidence for an important role for inferential reasoning in causal learning.
