The ethics in balancing control and freedom when engineering solutions for sustainable behaviour

Research suggests that to allow for sustainable development, consumption patterns must be changed. Individual behaviour is central to society's impact on the environment. However, due to the complexity of environmental issues, much of the political debate and technology development is inaccessible to consumers and based on the values, interpretations and priorities of experts. User‐centred, user‐involved and participatory processes are fundamental in design disciplines such as interaction design and participatory design. Research into the possibilities for cross‐pollination of design for sustainability and user‐centred design has distinguished several strategies for design‐led behavioural change. The strategies differ with regard to the levels of control and responsibility that users are left with, ranging from empowerment through information about consequences of behaviour to blocking behaviour or forcing sustainable practices upon individuals. By considering technological behaviour‐steering strategies in the light of science and technology studies and theory on technological mediation, the paper addresses the ethical issues that arise and discusses how designers can contribute to more sustainable consumption patterns without compromising quality of life, individual freedom and democratic rights.     

Framework for creating a Best-in-Class safety culture

To answer the question, “What are the practical attributes of Best-in-Class safety management,” consensus principles have been identified and lessons learned harvested from a broad spectrum of organizations with exemplary safety programs. Through years of studying the underpinnings of a strong safety culture, the authors have identified ten attributes that are important to create a Best-in-Class safety culture. Instead of expecting one organization to possess all of the attributes or employ all of the techniques identified, the authors suggest these principles be treated as guidelines that can be used to improve the safety culture in organizations.     

Value reclamation from informal municipal solid waste management: green neoliberalism and inclusive development in Lagos,Nigeria

ABSTRACT

Lagos is undoubtedly the cultural capital and economic hub of the West African sub-region. The challenge of municipal solid waste management (MSWM) in the megacity has remained intractable due partly to the increasing rate of population growth. While solid waste policy reforms, investments, and management practices in Lagos are in the upswing in the formal economy, the role of the informal economy in engendering sub-regional material linkages and livelihoods remain unexplored. Adopting a multi-stakeholder approach and data from interviews, this study critically examines how value reclamation from informal MSWM advances green neoliberalism and inclusive development. It shows that while informal transboundary trade of recyclable materials in the West African sub-region have previously been left out of analyses of MSWM in Lagos, the informal economy of waste and new investments in MSWM have neoliberal underpinnings beyond the megacity scale. The paper concludes that integrating the informal economy in framing MSWM policy in the megacity offers scope for evolving an inclusive development strategy while also enabling sustainable MSWM in the post-2015 era.     

The use of state workers' compensation administrative data to identify injury scenarios and quantify costs of work-related traumatic brain injuries

PROBLEM: Traumatic brain injury (TBI) is a public health problem but little is known about the nature of that problem in the working population. METHOD: The author used a national definition to identify cases in Washington State from workers' compensation (WC) hospital billing data, quantified the cost of WC insurance benefits using actuarial cost estimates, and identified high risk industries using ANSI Z16.2 typology. RESULTS: There were 928 cases of TBI with a lifetime claim cost of $159 million from the Washington State Fund (1994-2001). Sixty percent of injuries resulted in death or disability. The highest risks of TBI are concentrated in 16 industrial insurance risk classes and the highest costs in 19 North American Industry Classification codes. Injury scenarios were identified for nine industrial insurance risk classes. CONCLUSIONS: TBI is a disabling and costly workplace injury in the state of Washington, affecting even teenagers and seniors who are not generally considered to be part of the workforce. Injury typology codes provide useful information for improving workplace safety. IMPACT ON INDUSTRY: This research provides industry with quantitative information regarding the cost of work-related traumatic brain injury and the usefulness of using workers' compensation claims data to reduce the burden of workplace injury.

基于犹豫直觉模糊集-TOPSIS的危险品多式联运风险评估

为了对危险品的多式联运系统风险进行评估,首先在"人、机、管、环"4M理论的基础上,将多式联运中"转运"这一特殊流程考虑进去,以"人、机、管、环、转运"这5个因素作为决策问题中的属性;其次,采用犹豫直觉模糊语言集为决策者的初始决策矩阵赋值,并利用均值-标准差的汉明距离来衡量两个犹豫直觉模糊语言数之间的距离;然后,以危险品多式联运系统中的风险为标准,采用基于犹豫直觉模糊语言集的TOPSIS方法进行不同方案的决策。最后,以磷酸在宜昌-衢州之间的运输为案例,对4种常用运输方案进行风险评估,以综合评价指数进行对比。结果表明,在先水路后铁路、先水路后公路、先公路后铁路、先铁路后公路4种方案中,从宜昌到衢州之间先公路后铁路的运输方式所得综合评价值最高,应选择方案3。     

Assessing the efficiency gains of improved spatial targeting of policy interventions; the example of an agri-environmental scheme

GIS-based spatial targeting is increasingly recognised as a potentially useful tool to design more efficient policy interventions. The use of this tool has also been advocated in the context of incentive-based agri-environmental schemes, but there has been little work to date to estimate the level of efficiency gains which it may help to achieve. This paper investigates the requirements to arrive at such estimates, using a Scottish farm woodland scheme as a case study. This agri-environmental scheme aims to provide visual amenity and biodiversity. Maps of these two benefits are used to develop improved spatial targeting scenarios that deliver significant efficiency gains in comparison to the existing scheme design. The paper discusses the nature of the spatial distribution of the relevant benefits at the landscape scale and the data requirements for the realistic estimation of efficiency gains. It concludes that although much work needs to be done, the methods available today could and should play a much greater role in improving the landscape-scale design of existing land use schemes focused on the delivery of non-market benefits.     

Initiatives and outcomes of green supply chain management implementation by Chinese manufacturers

This paper aims to explore the green supply chain management (GSCM) initiatives (implementation) of various manufacturing industrial sectors in China and examine the links between GSCM initiatives and performance outcomes. We conducted a survey to collect data from four typical manufacturing industrial sectors in China, namely, power generating, chemical/petroleum, electrical/electronic and automobile, and received 171 valid organizational responses for data analysis. Analysis of variance (ANOVA) was used to analyze the data. The results are consistent with our prediction that the different manufacturing industry types display different levels of GSCM implementation and outcomes. We specifically found that the electrical/electronic industry has relatively higher levels of GSCM implementation and achieves better performance outcomes than the other three manufacturer types. Implications of the results are discussed and suggestions for further research on the implementation of GSCM are offered.     

An integrated assessment model of carbon sequestration benefits: a case study of Liping county, China

This research attempts to model the complexity of planting trees to increase China's CO(2) sequestration potential by using a GIS-based integrated assessment (IA) approach. We use the IA model to assess the impact of China's Grain for Green reforestation and afforestation program on farmer and state incomes as well as CO(2) sequestration in Liping County, Guizhou Province. The IA model consists of five sub-models for carbon sequestration, crop income, timber income, Grain for Green, and carbon credits. It also includes a complementary qualitative module for assessing program impacts by gender and ethnicity. Using four scenarios with various assumptions about types of trees planted, crop incomes by township, CO(2) credit prices, state subsidies, methods for estimating carbon sequestered, and harvesting of trees, we find great variation in the impact of the Grain for Green program on incomes and on carbon sequestered over a 48 year period at both the county and township levels.     

Assessing the ecosystem service of air pollutant removal by urban trees in Guangzhou (China)

In Chinese cities, air pollution has become a serious and aggravating environmental problem undermining the sustainability of urban ecosystems and the quality of urban life. Besides technical solutions to abate air pollution, urban vegetation is increasingly recognized as an alternative ameliorative method by removing some pollutants mainly through dry deposition process. This paper assesses the capability and monetary value of this ecosystem service in Guangzhou city in South China. The results indicated an annual removal of SO(2), NO(2) and total suspended particulates at about 312.03Mg, and the benefits were valued at RMB90.19 thousand (US$1.00=RMB8.26). More removal was realized by recreational land use due to a higher tree cover. Higher concentration of pollutants in the dry winter months induced more removal. The lower cost of pollution abatement in China generated a relatively subdued monetary value of this environmental benefit in comparison with developed countries. Younger districts with more extensive urban trees stripped more pollutants from the air, and this capacity was anticipated to increase further as their trees gradually reach final dimensions and establish a greater tree cover. Tree cover and pollutant concentration constitute the main factors in pollutant removal by urban trees. The efficiency of atmospheric cleansing by trees in congested Chinese cities could be improved by planting more trees other than shrubs or grass, diversifying species composition and biomass structure, and providing sound green space management. The implications for greenery design were discussed with a view to maximizing this ecosystem service in Chinese cities and other developing metropolises.
