道家的道与海德格尔的开辟道路

海德格尔认为,他的道路和道家的道之所以一脉相承,不是说二者都指称着由此达彼的桥梁,也不是指称通达天地、贯通阴阳最终存在意义的道路。海德格尔认为他的道路和道家的道含藏着思悟道说的一切神秘。道路和道家之道作为本源之道是使天地万物成其自身的渊源。     

基于价格歧视理论分析我国销售电价的制定

电力行业是关系国计民生的重要行业,长期以来该行业一直都是国家垄断行业。但是电力行业垄断在带来规模经济的同时也造成企业效率低下,财务亏损等负面影响。近年来,国家一直致力于电力改革,尤其是对于销售电价制定的改革。以经济学中的价格歧视理论为基础,从近期销售电价变动原因入手,分析了单一加成成本定价和补贴价格中存在的问题,并据此提出了在销售电价制定的改革中应该完善和深化价格歧视理论的应用,并且充分考虑销售电价制定体系中的多种市场因素,以期为完善电力改革提供参考。

Introduction to the Special Forum on Critical Making as Research Program

This special issue spotlights the growing diversity of critical making practices in a range of disciplinary contexts both inside and outside of the academy, and begins to develop perspectives that will foster the emergence of critical making as a coherent field. On one hand, we see great value in incorporating material practices into existing information systems (IS) and science and technology studies (STS) research programs. In particular, forms of material engagement can help overcome the ineffectual linguistic bias of traditional critiques of technoscience. On the other hand, we believe that current material practices can benefit from the conceptualization of knowledge and social organization that are foundational to IS and STS research. In this introduction to the special issue we call attention to the mechanisms by which such practices may combine representational and material work to foster and support the development of new knowledge-making communities and institutions. We believe such work can serve as a framework for others engaged in critical making practices to better contextualize and expand the relevance of their work. We intend this special issue to serve as a “stake in the ground” for research on new forms of material-conceptual critique and their incorporation in the repertoire of critical technoscience scholarship.

Children's Thinking about Air Pollution: a systems theory analysis

A methodology for probing systems thinking was developed and used to investigate the way children think about the natural environment. Thirty five primary school children (aged 8 and 11 years) participated in semi‐structured interviews about air pollution. The analytical framework consisted of cycles (of inputs, processes and outputs), interventions, outcomes and links. Differences between the groups were found for the numbers of complete cycles, inputs, outputs and longest chain of linked cycles about which the children could talk. Although more of the older children showed evidence of a high level of systemic thinking — cycles with interventions and their likely outcomes — than the younger children, a large proportion of the 8‐year‐olds demonstrated that they were capable of this kind of thinking. The results suggest that children can engage in systemic thinking earlier than predicted by traditional developmental research.
