对技术发展所作的人文思考在很大程度上是一些伦理或与伦理学密切相关的问题。当我们通过这样一些本该属于伦理学的概念,譬如善、恶、责任、公平、自由等去看待技术的发展时,就要涉及到技术或工程伦理的观点。前苏联和俄罗斯哲学家提出的一系列为技术的发展和应用做道德辩护的原创性思想,为我国工程伦理学的建立和发展提供了借鉴。 相似文献

With more than 28 active members, the Mediterranean Engineering Schools Network (RMEI) is the most active network on gender equality in the Mediterranean area. Supported by the HORIZON2020 TARGET project ‘Taking a Reflexive Approach to Gender Equality for Institutional Transformation’, in conceptualizing gender equality learning and system change, the network took a context-specific approach based on a theory of change and other STEM organizational frameworks, to design a self-assessment framework and indicators, considering the systemic view of SDG5 horizontally connected to all SDGs, national context complexity, and transdisciplinary requirements. 95 simple, practical, user-friendly indicators were designed, fitting in the specificities of the Mediterranean-Engineering context. The analysis showed that the network realized its vision, made the ‘passage’ from theory to praxis on gender equality change, effectively developed meaningful processes/structures, formulated a policy statement, built a community of practice and inspired members. It also achieved trustful relationships and inspired outputs, effective communication, sharing of information and resources, and top management commitment. Critical aspects are a) the analysis in depth of issues linked to the existence of gender-based stereotypes and bias in engineering schools of the Mediterranean that entails tackling gender ideologies considering the whole national social system and existing structures; b) sustainability of gender equality structures created at the member institutions with the support of TARGET project which is depending on the willingness of institution’s leaders to continue/advance with gender-sensitive strategies in their institution. 相似文献

This article gives a unified account of nonparametric statistics, covering testing, estimating, multiple comparisons, analysis of variance and regression, for rounded-off data, with ties handled by the average scores method. The theory is illustrated by means of numerous applications to the Biomedical, Engineering and Behavioral Sciences. 相似文献

This paper describes a new approach to extended enterprise engineering and operation-embedding knowledge management and work-tops for work execution. The approach is based on web technologies and a new technology we call active knowledge models (AKM). By developing and using AKMs of extended enterprises, most methodologies, work environments and business solutions will converge. Enterprises will be integrated by externalized shareable knowledge. During forming and managing of extended enterprises, knowledgesharing infrastructures and the process of generating operational solutions will be simplified and facilitated. Extended enterprises will be engineered and managed as reflective, selfadapting AKMs. By using process-oriented methods to externalize internal and tacit knowledge, the AKM technology provides an environment of work-tops and views to produce, share, cultivate and manage situated knowledge. This knowledge will be applied and managed as competences and skills, and as improved methods. AKMs let us benefit from the intrinsic properties of knowledge. They facilitate convergence of methodologies and integration of technologies. 相似文献

The basic master production scheduling problem assumes that periodic demands are known with certainty. Uncertainty in the forecasts arc typically accommodated afterwards by adding safety stocks to a schedule. Two popular methods for establishing safety stocks are: (1) the constant cycle service level method; and (2) the constant safety stock method. This paper outlines these methods and then develops a third method which results in optimal safety stocks. The paper includes an experimental investigation aimed at comparing performances of the three safety stock methods. The constant safety stock method is shown to perform within one or two per cent of optimal, while the constant cycle service level method performs worse under most conditions. Shorter lead times, variable order interval lengths, and time-dependent forecast errors all adversely affect the performances of the non-optimal methods. An operations manager could use these results to evaluate the appropriateness of the methods for his master production scheduling environment. 相似文献

Abstract Despite the fact that women engineering students perform as well as their male classmates during college, women engineers report lower salaries and supervisory responsibility levels after about five years in the labour force. Several hypotheses concerning the reasons for the differences in career advancement of men and women engineers were investigated in a national survey of engineers in the United States. The gender differences in career advancement could not be explained by differences in education level or in self-perceptions of ability. The fact that women were more likely to have taken a career break than were men did decrease their salaries and supervisory levels. However, gender differences were still apparent even when this factor was controlled. The careers of both men and women were affected by conflicts arising from the multiple roles of worker, spouse, and parent, but many women engineers avoided such conflicts by remaining single and childless. These results challenge several popular explanations for the differential advancement of men and women, but the actual causes remain unknown. 相似文献
