Efficiency of triggered barriers in dust explosion suppression in galleries

The paper describes large-scale tests of triggered barriers of different design. Main stress was put on examining suitability of the flame detector developed in US Bureau of Mines to work as a trigger for the barriers. It was found that the detector works satisfactorily with the barriers of different design providing a suitable mean to suppress explosions in galleries, either in mines or in other industries.

Tourists and disasters: lessons from the 26 December 2004 tsunamis

The 26 December 2004 tsunamis around the Indian Ocean exposed the vulnerability of many coastal communities, including those serving tourists. To draw conclusions regarding disaster risk reduction for tourism in coastal areas, this study surveyed international tourists who survived the tsunami regarding their perceptions and experiences of the disaster. Semi-structured interviews were completed between January and June 2005 of 55 primary interviewees who were international tourists in locations affected by the tsunami. The qualitative data from the interviews yielded commonalities across four main themes with relevance to disaster risk reduction: information and awareness, warning systems, personal preparation, and livelihoods. Three areas are suggested as topics to highlight for further investigation: the connections between sustainable tourism and disaster vulnerability, the role of tourists in disasters, and disaster risk reduction education.

Public Discourse and the Rhetorical Construction of the Technospecter

Modern technological disasters and their human and environmental consequences often defy the imagination in their immensity and complexity. As such, their rhetorical constructions often lack tangibility and a sense of material reality for those not directly involved. These amorphous constructions are consolidated into a view of technological disaster and threats of disaster in which the rhetorical dimensions are analogous to those of ghosts portrayed in popular literature and film—a view the author terms the “technospecter.” Drawing on the public discourse surrounding a tragic pipeline explosion near Carlsbad, New Mexico, this study identifies the rhetorical dimensions of the technospecter and discusses how the construction of the specter reinforces the meta-narratives that constrain pro-environmental action.     

Continuous Safety Sampling Methodology

This research introduces a proactive methodology for accident prevention, called Continuous Safety Sampling Methodology, by utilizing the principles of work sampling and control charting. Sampling is performed to observe the occurrence of conditions that may become hazardous in a given system. These conditions, known as dendritics, may become hazards and could result in an accident or occupational disease. Continuous Safety Sampling Methodology performs a random sampling for the occurrence of these dendritics. The collected data are then used to generate a control chart. Based on the pattern of the control chart, a system “under control” is not disturbed whereas a system “out of control” is investigated for potential conditions becoming hazardous. Appropriate steps are then taken to eliminate or control these conditions to maintain a desired safe system.     

Spaghetti soup: The complex world of food waste behaviours

There is growing awareness of the positive impact of reducing the amount of wasted food on greenhouse gas emissions, energy use, food and water security, and land use. In developed nations, food waste generated in homes is a large contributor to the total amount of food waste. The behaviours and practices associated with this waste prevention (and waste generation) are complex for a number of reasons: food waste is the result of multiple, interacting activities and this leads to separation between the activity and their consequences. These behaviours are usually performed for reasons unrelated to waste prevention and have both a marked habitual element and a pronounced emotional component. Furthermore, the prevention of food waste has less ‘visibility’ to other people (e.g. neighbours) than many other pro-environmental behaviours (e.g. recycling), and therefore social norms around ‘waste’ play a reduced role compared to more ‘visible’ activities.This paper discusses insights into these behaviours from research funded by the Waste & Resources Action Programme (WRAP) and its partners in the UK. It discusses how these insights have been used in the development of a successful public-engagement campaign, which has been influential in the recent reduction in household food waste. These insights are also discussed in light of commonly used behavioural models, highlighting that many of these models are not designed for multiple, complex behaviours. However, considering the subject of food waste through the ‘lenses’ of different academic disciplines has helped the development of the public engagement on this issue.     

Moving up the waste hierarchy: Car boot sales,reuse exchange and the challenges of consumer culture to waste prevention

Moving up the waste hierarchy is a key priority for UK waste policy. Waste prevention requires policy interventions to promote reuse. The term ‘reuse exchange’ has been adopted by UK policy makers to describe a variety of second-hand trading outlets including car boot sales, charity shops and online exchange sites. As waste policy is based on tonnage diverted from disposal (or landfill), policy interventions to promote reuse exchange will be based on the weight of goods estimated to be flowing through these sites. This paper uses a combination of field survey data and scale-up estimation to quantify and characterise the weight of goods exchanged at car boot sales in England in 2012. This is estimated at 50–60 000 tonnes per annum. The paper emphasises that movement up the waste hierarchy brings waste policy into closer contact with household consumption practices. It draws on qualitative research to show that, for participants, car boot sales are not associated with waste prevention. Instead, car boot sales rely on stocks of surplus household goods and exemplify the culture of thrift, which enables more, not less, consumption. The paper shows the collision between the social values that inform thrift and the environmental values that underpin reuse; and it argues that the policy goal of enhanced recovery for reuse might best be achieved by working with consumer culture. Two ways of achieving this are suggested: interventions that make it easier for consumers to do the right thing, through promoting opportunities for the circulation of stocks of surplus goods, for example, through increasing the frequency of car boot sales; and interventions which recognise that car boot sales also generate waste, which could be recovered for reuse.     

传统中医学理论与企业安全生产风险管理

笔者将传统中医学理论与企业安全生产风险管理相结合,在事故致因、事故预防、安全管理等方面,借鉴中医的预防思想、整体观念、五行学说、辨证施治等理论方法,分析研究指出:企业发生安全事故如同人体得病,正气不足是发病的内在根据,邪气入侵是发病的重要条件。因此,发生事故的根本原因在于企业本身;要从研究企业自身的影响安全生产诸要素之间的相互滋生和相互制约的关系入手,加强事故预防工作,坚持整体性的原则,辨证分析事故原因,加大企业生产安全的精神和物质保障,才能全面提高企业的生产安全风险管理水平。
