Accounting for human rights : doxic health and safety practices - the accounting lessons from ICL

This paper is concerned with a specific human right - the right to work in a safe environment. It sets out a case for developing a new form of account of health and safety in any organisational setting. It draws upon the theoretical insights of Pierre Bourdieu taking inspiration from his assertion that in order to understand the 'logic' of the worlds we live in we need to immerse ourselves into the particularity of an empirical reality. In this case the paper, analyses a preventable industrial disaster which occurred in Glasgow, Scotland which killed nine people and injured 33 others. From this special case of what is possible, the paper unearths the underlying structures of symbolic violence of the UK State, the Health and Safety Executive and capital with respect to health and safety at work. While dealing with one specific country (Scotland), the analysis can be used to question health and safety regimes and other forms of symbolic violence across the globe

Active clearance control system for a turbomachine

An axial compressor is provided with a cooling air manifold surrounding a portion of the shroud, and means for bleeding air from the compressor to the manifold for selectively flowing it in a modulating manner axially along the outer side of the stator/shroud to cool and shrink it during steady state operating conditions so as to obtain minimum shroud/rotor clearance conditions. Provision is also made to selectively divert the flow of cooling air from the manifold during transient periods of operation so as to alter the thermal growth or shrink rate of the stator/shroud and result in adequate clearance with the compressor rotor

A sensory-guided surgical micro-drill

This is the author's accepted manuscript. The final published article is available from the link below. Copyright @ 2010 The Authors.This article describes a surgical robotic device that is able to discriminate tissue interfaces and other controlling parameters ahead of the drill tip. The advantage in such a surgery is that the tissues at the interfaces can be preserved. A smart tool detects ahead of the tool point and is able to control the interaction with respect to the flexing tissue, to avoid penetration or to control the extent of protrusion with respect to the position of the tissue. For surgical procedures, where precision is required, the tool offers significant benefit. To interpret the drilling conditions and the conditions leading up to breakthrough at a tissue interface, a sensing scheme is used that discriminates between the variety of conditions posed in the drilling environment. The result is a fully autonomous system, which is able to respond to the tissue type, behaviour, and deflection in real-time. The system is also robust in terms of disturbances encountered in the operating theatre. The device is pragmatic. It is intuitive to use, efficient to set up, and uses standard drill bits. The micro-drill, which has been used to prepare cochleostomies in the theatre, was used to remove the bone tissue leaving the endosteal membrane intact. This has enabled the preservation of sterility and the drilling debris to be removed prior to the insertion of the electrode. It is expected that this technique will promote the preservation of hearing and reduce the possibility of complications. The article describes the device (including simulated drill progress and hardware set-up) and the stages leading up to its use in the theatre.Queen Elizabeth Hospital, Birmingham, U

The ecology of cooperation: considerations for litter research

This article examines the role of intertemporal choice and relative inequality, with a focus on how socioeconomic conditions and environmental pressures can yield differing cooperative strategies which impact on littering behaviour and anti-littering interventions. We apply a framework emerging from behavioural biology that has great explanatory utility and which permits researchers to consider a frequently overlooked element in littering, which is key variation within populations

The western blue groper (Achoerodus gouldii), a protogynous hermaphroditic labrid with exceptional longevity, late maturity, slow growth, and both late maturation and sex change

The western blue groper (Achoerodus gouldii) is shown to be a temperate protogynous hermaphrodite, which spawns between early winter and mid-spring. Because A. gouldii changes body color at about the time of sex change, its color can be used as a proxy for sex for estimating the size and age at sex change and for estimating growth when it is not possible to use gonads for determining the sex of this fish. The following characteristics make A. gouldii highly susceptible to overfishing: 1) exceptional longevity, with a maximum age (70 years) that is by far the greatest yet estimated for a labrid; 2) slow growth for the first 15 years and little subsequent growth by females; and 3) late maturation at a large total length (TL50 = 653 mm) and old age (~17 years) and 4) late sex change at an even greater total length (TL50 = 821 mm) and age (~35 years). The TL50 at maturity and particularly at sex change exceeded the minimum legal total length (500 mm) of A. gouldii and the lengths of many recreationally and commercially caught fish. Many of these characteristics are found in certain deep-water fishes that are likewise considered susceptible to overfishing. Indeed, although fishing effort for A. gouldii in Western Australia is not particularly high, per-recruit analyses indicate that this species is already close to or fully exploited

Feasibility study of a hand guided robotic drill for cochleostomy

The concept of a hand guided robotic drill has been inspired by an automated, arm supported robotic drill recently applied in clinical practice to produce cochleostomies without penetrating the endosteum ready for inserting cochlear electrodes. The smart tactile sensing scheme within the drill enables precise control of the state of interaction between tissues and tools in real-time. This paper reports development studies of the hand guided robotic drill where the same consistent outcomes, augmentation of surgeon control and skill, and similar reduction of induced disturbances on the hearing organ are achieved. The device operates with differing presentation of tissues resulting from variation in anatomy and demonstrates the ability to control or avoid penetration of tissue layers as required and to respond to intended rather than involuntary motion of the surgeon operator. The advantage of hand guided over an arm supported system is that it offers flexibility in adjusting the drilling trajectory. This can be important to initiate cutting on a hard convex tissue surface without slipping and then to proceed on the desired trajectory after cutting has commenced. The results for trials on phantoms show that drill unit compliance is an important factor in the design

The Hybrid Master\u27s Degree: Combining Research with Practice

The article discusses the development of a hybrid master degree program by the Donald W. Reynolds School of Journalism at the University of Nevada in Reno. Since the journalism faculty of the school is too small to offer a full-service master\u27s degree, the school developed a hybrid program that integrates systematic research with practice-based education. The program is designed to equip students with knowledge in academic research in preparation to doctoral studies. The program also emphasizes the study of mass media to prepare students for professional careers in broadcast journalism

Energy dependence on fractional charge for strongly interacting subsystems

The energies of a pair of strongly-interacting subsystems with arbitrary noninteger charges are examined from closed and open system perspectives. An ensemble representation of the charge dependence is derived, valid at all interaction strengths. Transforming from resonance-state ionicity to ensemble charge dependence imposes physical constraints on the occupation numbers in the strong-interaction limit. For open systems, the chemical potential is evaluated using microscopic and thermodynamic models, leading to a novel correlation between ground-state charge and an electronic temperature.Comment: 4 pages, 3 figs.; as accepted (Phys.

Real feelings for virtual people: emotional attachments and interpersonal attraction in video games

Factors which may affect how people become attracted to virtual characters were explored in an online survey of players of a recent video role-playing game. Seventy-four participants (33 male) completed a series of questionnaires assessing their personality, motivations for game play, and feelings towards the ten non-player characters (NPCs) with whom they had potentially experienced extensive interactions within the game world. Results suggest that people form real and authentic emotional attachments to virtual characters, and that these arise from a complex blend of the players’ personality and motivation, and the virtual characters’ levels of physical attraction, friendliness (or hostility) and general usefulness within the game context. Implications of these findings, and suggestions for future research, are discussed
