The burgeoning literature on the ethical issues raised by climate engineering has explored various normative questions associated with the research and deployment of climate engineering, and has examined a number of responses to them. While researchers have noted the ethical issues from climate engineering are global in nature, much of the discussion proceeds predominately with ethical framework in the Anglo‐American and European traditions, which presume particular normative standpoints and understandings of human–nature relationship. The current discussion on the ethical issues, therefore, is far from being a genuine global dialogue. The aim of this article is to address the lack of intercultural exchange by exploring the ethics of climate engineering from a perspective of Confucian environmental ethics. Drawing from the existing discussion on Confucian environmental ethics and Confucian ethics of technology, I discuss what Confucian ethics can contribute to the ethical debate on climate engineering.  相似文献

Fatigue crack growth experiments were conducted in humid air (RH~45%) at 25 °C on 29-mm-thick plate samples of an aluminium–magnesium (Al–Mg) 5083-H131 alloy in the long transverse (LT) direction. Samples were tested in both the as-received condition and after sensitization at 175 °C for 100 h. Delamination along some grain boundaries was observed in the short transverse plane after fatigue testing of the sensitized material, depending upon the level of ΔK and Kmax. Orientation microscopy using electron backscattering diffraction and chemical analyses using transmission electron microscopy and energy dispersive spectroscopy of grain boundaries revealed that Mg segregation and the orientation of grains had key roles in the observed grain boundary delamination of the sensitized material.  相似文献

The mechanical behaviour of polycrystalline hexagonal close-packed cobalt was investigated over a large range of grain size d in order to examine the occurrence of size effects. Crystallographic texture and amount of face centred cubic allotropic phase were maintained unchanged thanks to appropriate heat treatment procedures. The Hall–Petch (HP) relation exhibits two distinct behaviours from the very beginning of plastic strain levels. The conventional HP law is fulfilled for a number of grains across the thickness t higher than a critical value (t/d)c = 14. For t/d lower than (t/d)c, a multicrystalline regime is evidenced highlighting a strong reduction in flow stress. The high value of (t/d)c is related to the low-stacking fault energy of cobalt in the basal plane. The size effect is predominant in the first work hardening stage where slip mechanisms and stacking faults predominate. In the second stage, driven by mechanical twinning processes, this effect is less sensitive. Finally, the size effect could also affect the end of the elastic stage, in link with nonlinear elasticity mechanisms.  相似文献

Although education in the responsible conduct of research is considered necessary, evidence bearing on the effectiveness of these programs in improving research ethics has indicated that, although some programs are successful, many fail. Accordingly, there is a need for systematic evaluation of ethics education programs. In the present effort, we examine procedures for evaluation of ethics education programs from a multilevel perspective: examining both within-program evaluation and cross-program evaluation. With regard to within-program evaluation, we note requisite designs and measures for conducting systematic program evaluation have been developed and multiple measures should be applied in program evaluation. With regard to cross-program evaluation, we argue that a meta-analytic framework should be employed where analyses are used to identify best practices in ethics education. The implications of this multilevel approach for improving responsible conduct of research educational programs are discussed.  相似文献

In this paper I investigate how conceptual engineering applies to mathematical concepts in particular. I begin with a discussion of Waismann’s notion of open texture, and compare it to Shapiro’s modern usage of the term. Next I set out the position taken by Lakatos which sees mathematical concepts as dynamic and open to improvement and development, arguing that Waismann’s open texture applies to mathematical concepts too. With the perspective of mathematics as open-textured, I make the case that this allows us to deploy the tools of conceptual engineering in mathematics. I will examine Cappelen’s recent argument that there are no conceptual safe spaces and consider whether mathematics constitutes a counterexample. I argue that it does not, drawing on Haslanger’s distinction between manifest and operative concepts, and applying this in a novel way to set-theoretic foundations. I then set out some of the questions that need to be engaged with to establish mathematics as involving a kind of conceptual engineering. I finish with a case study of how the tools of conceptual engineering will give us a way to progress in the debate between advocates of the Universe view and the Multiverse view in set theory.  相似文献

The aim of this study was to explore the extent to which persuasion principles are used in successful social engineering attacks. Seventy‐four scenarios were extracted from 4 books on social engineering (written by social engineers) and analysed. Each scenario was split into attack steps, containing single interactions between offender and target. For each attack step, persuasion principles were identified. The main findings are that (a) persuasion principles are often used in social engineering attacks, (b) authority (1 of the 6 persuasion principles) is used considerably more often than others, and (c) single‐principle attack steps occur more often than multiple‐principle ones. The social engineers identified in the scenarios more often used persuasion principles compared to other social influences. The scenario analysis illustrates how to exploit the human element in security. The findings support the view that security mechanisms should include not only technical but also social countermeasures.  相似文献

As governments mandated organization and school closures due to COVID-19, working parents involuntarily found themselves trying to balance both work and child educational responsibilities from home while still endeavoring to remain productive at work. As such, we integrate the crisis management literature with boundary theory and the work–home resources model to propose and test a process model to better understand how abrupt shifts to remote work and school closures impact working parents' job performance during a crisis. Using data collected across four time periods beginning at the time when most states had issued “safer at home” orders, we examine a serial mediation model and find, consistent with predictions, that early experiences of boundary violations and job insecurity impact work–family balance self-efficacy, which in turn drives future job performance by way of its effects on working parents' subjective well-being. Implications for theory and practice are discussed.  相似文献

通过四个实验考察句子边界对整体连贯性的影响。实验运用不一致程序(inconsistent paradigm)进行。实验一结果发现,当目标行1(target line)不是一个完整句子时,被试阅读完目标行2(post-target line)后才会意识到目标行1中的不一致。实验二结果发现,当目标行1是一个完整句子时,被试阅读完目标行1后就可立刻意识到其中的不一致,但探测词的反应时在两种条件下则并没有明显差异。这两个实验的结果表明,句子边界作为一种信号,提示读者在阅读下一句子前要完成当前句子的整合加工。实验三结果发现,目标行1以一个无关词(如然后)结束时,被试阅读完目标行1后也可立刻注意到其中的不一致,这表明句号对背景信息的整合不是必需的。实验四考察了分号的作用,结果显示:被试阅读完目标行1后并没有意识到其中的冲突。根据本研究的结果,可以推测句号在理解过程中起着重要影响,而其它句子边界(如:分号)的作用则并不明显。  相似文献

Awareness of boundary, both physical and mental, is seen as the beginning of perception. In any account of the world, therefore, boundary must be a ubiquitous component. In sharp contrast, accounts of God within the Christian tradition commonly have proceeded by the affirmation that God is above and beyond boundary as infinite, timeless, and simple. To overcome this “problem of transcendence,” of how such a God can relate to such a world, an eight‐term grammar of boundary is developed to demonstrate how God as Trinity can properly be held to be without boundary yet constitute the ground of a bounded world. This leads to a way of granting theological significance to the origin and development of life. Life is seen to exist in dynamic, intentional relationships between context (“outside”) and intext (“inside”) across permeable boundaries through which an exchange of resources and information takes place for the sake of self‐continuation. Comprehending life's distinctive utilization of boundary in terms of the grammar developed here enables life to be seen not only as a vestige of the Trinity but also, precisely because of this, as a sign and parable of redemption.  相似文献
