Developing the ethical matrix as a decision support framework: GM fish as a case study 总被引:2,自引:0,他引:2
Matthias Kaiser Kate Millar Erik Thorstensen Sandy Tomkins 《Journal of Agricultural and Environmental Ethics》2007,20(1):65-80
The Ethical Matrix was developed to help decision-makers explore the ethical issues raised by agri-food biotechnologies. Over
the decade since its inception the Ethical Matrix has been used by a number of organizations and the philosophical basis of
the framework has been discussed and analyzed extensively. The role of tools such as the Ethical Matrix in public policy decision-making
has received increasing attention. In order to further develop the methodological aspects of the Ethical Matrix method, work
was carried out to study the potential role of the Ethical Matrix as a decision support framework. When considering which
frameworks to apply when analyzing the ethical dimensions of the application of agri-food biotechnologies, it is important
to clarify the substantive nature of any prospective framework. In order to further investigate this issue, reflections on
the neologism “ethical soundness” of an ethical framework are presented here. This concept is introduced in order to provide
more structured evaluations of a range of ethical tools, including ethical frameworks such as the Ethical Matrix. As well
as examining the philosophical dimensions of the method, theoretical analysis and literature studies were combined with stakeholder
engagement exercises and consultations in order to review the Ethical Matrix from a user perspective. This work resulted in
the development of an Ethical Matrix Manual, which is intended to act as a guide for potential user groups. 相似文献

Improvements in production methods over the last two decades have resulted in aquaculture becoming a significant contributor
to food production in many countries. Increased efficiency and production levels are off-setting unsustainable capture fishing
practices and contributing to food security, particularly in a number of developing countries. The challenge for the rapidly
growing aquaculture industry is to develop and apply technologies that ensure sustainable production methods that will reduce
environmental damage, increase productivity across the sector, and respect the diverse social and cultural dimensions of fish
farming that are observed globally. The aquaculture industry currently faces a number of technology trajectories, which include
the option to commercially produce genetically modified (GM) fish. The use of genetic modification in aquaculture has the
potential to contribute to increased food security and is claimed to be the next logical step for the industry. However, the
potential use of these technologies raises a number of important ethical questions. Using an ethical framework, the Ethical
Matrix, this paper explores a number of the ethical issues potentially raised by the use of GM technologies in aquaculture.
Several key issues have been identified. These include aspects of distributive justice for producers; use of a precautionary
approach in the management of environmental risk and food safety; and impacts on the welfare and intrinsic value of the fish.
There is a need to conduct a comparative analysis of the full economic cycle of the use of GM fish in aquaculture production
for developing countries. There is also a need to initiate an informed dialogue between stakeholders and strenuous efforts
should be made to ensure the participation of producers and their representatives from developing nations. An additional concern
is that any national licensing of the first generation of GM fish, i.e., in the USA, may initiate and frame an assessment
cycle, mediated by the WTO, which could dominate the conditions under which the technology will be applied and regulated globally.
Therefore, an integrated analysis of the technology development trajectories, in terms of international policy, IPR, and operational
implications, as well as an analysis of a broader range of ethical concerns, is needed. 相似文献

CFG桩复合地基的工后沉降受到多种不确定因素的影响。本文根据灰色系统理论的处理方法,分别采用普通GM(1,1)模型、新息GM(1,1)模型和新陈代谢GM(1,1)模型,对采用CFG桩进行地基处理的某建筑物地基沉降进行了预测。结果表明:新陈代谢GM(1,1)模型由于淘汰掉旧的沉降数据、加入新的沉降数据,所以能够更准确地模拟CFG桩复合地基沉降的真实情况。 相似文献

目的建立预测精度较好的大气温度监测缺失数据修补的方法和模型。方法采用正弦函数对GM(1,1)标准模型进行修正,建立分段的GM(1,1)正弦修正模型对缺失数据进行修补。以万宁试验站某天监测的温度日记时值数据为试验数据,同时建立GM(1,1)标准模型、GM(1,1)时序修正模型和GM(1,1)正弦修正模型,对比分析各模型的修补误差,确立较好的修补模型。结果从模型的拟合效果分析,GM(1,1)标准模型和GM(1,1)正弦修正模型的拟合性最好,GM(1,1)时序修正模型的拟合性相对较差一些;从预测精度上分析,GM(1,1)标准模型和GM(1,1)时序修正模型预测修补效果差,平均相对误差分别达到22.54%和17.70%,而GM(1,1)正弦修正模型预测修补的平均误差仅为3.14%,得到了较大的改进,预测效果好。结论正弦修正模型能很好地修补缺失数据,其修补效果比时序修正模型和标准模型都要好。 相似文献
