能效标识对节能产品选择的引导效用分析——基于京东家电线上销售的实证检验

搜集冰箱、洗衣机、空调三种大家电的线上销售数据,通过描述性分析、组间差异比较、多元回归分析等方式分析能效标识的市场引导效果。结果显示消费者对不同等级家电产品的选择量存在差异,但不同能效等级间消费者满意度并无明显差异,能效等级并非是影响消费者选择和满意度的显著因素。     

基于过程划分的可再生能源技术扩散模型

把握技术扩散的机理和主要特征是可再生能源发展规划和管理优化的基础。本文基于信息扩散、技术经济、社会认可度等因素对可再生能源技术的影响及其作用机理分析,根据投资者状态变化,将技术扩散过程划分为技术获悉、效益计算和技术认可三个阶段,构建了可再生能源技术扩散(即潜在投资者转变为最终投资者)过程的数理模型。探讨了可再生能源技术扩散的速度有限性、政策效率递减性以及区域差异性三个关键特征,结合算例验证模型并进一步分析了技术扩散的不同驱动力,从而为可再生能源技术扩散机理政策制定提供理论支持和意见建议。

Another economy: towards a cultural dialectics between energy and society

The looming oil crisis, pollution, and climate change have pushed governments, corporations, and individuals to think of new policies, new objects/products and new manners to market them – usually under the label of “green economy” (or the shifting towards a sustainable economy).

The changes that are on the way as a result of the envisaged “green revolution” need a broad vision that couples the economy of energetic techniques with the related socio-cultural economy that is induced by, and at the same time reciprocally influences, the mere technical transformations.

Based on previous analysis of theories of socio-technological change and putting at its center the concept of subjectivation in social sciences, this article proposes a theoretical understanding of cultural shifts and their relationship with changes in the practices of production, transfer and use of energy.

First part presents a schema of subjectivation in triangulation, that links the biological level with the material culture and with the representational realm of normativities in our society. It will be developed through the example of electric vehicle as metaphor of the energetic transition. Through this understanding, second part deals with the modeling of the three items as a processual energetic system by using the concepts of surplus and expenditure. Within this frame, we show how disruptions in one of the poles of this model influences the others and bring about changes in the entire Anthropo-Social level. Third part proposes possible types of emerging subjectivities and advances the idea of extending the realm of consciousness to the energetic transfers and their potentiality.     

基于功率约束及节点频谱选择的认知协同路由

为了提升认知无线网络的数据传输效率,优化节点能量负载,提出一种协同路由算法。基于覆盖与底层技术的协作设计一种协同网络架构,该架构针对网络频带表现多样化提供了一种新的频谱选择策略,提升频谱资源效用。结合协同网络频谱选择时的干扰特性,根据频谱、干扰和功率约束关系,提出最大化链路容量的频谱及节点功率分配方法。在协同路由设计上引入了频谱效用参数,参数的度量标准涉及节点剩余能量和链路容量,以优化路由节点能量负载和传输效率为目的。仿真对比结果表明,算法有效地利用信道接入机会进行数据转发,提高了传输效率,相比基于竞争进化算法的多播路由方法,数据包传递成功率提升了1．4％,平均网络吞吐量高出8．4％,平均节点剩余能量高出3．2％,在均衡节点负载上性能良好。     

Theorizing the social: Émile Durkheim's theory of force and energy

This paper offers a new interpretation of Émile Durkheim's The Elementary Forms of Religious Life (1912) as the basis for reconsidering the Tarde–Durkheim debate of 1903 and the distinctions between a theory of social force and a theory of social assemblage. Resisting traditional interpretations of Durkheim's scientism, this essay traces how concepts of force and energy are centrally developed in Elementary Forms to draw new lines between epistemology to ontology for twentieth-century theory. I argue that Durkheim develops an ‘energetic epistemology’ that conceives of the human capacity for shared meaning as a product of invested energy in the form of continually enacted and evolving material practice, thought, and attention. According to Durkheim, when a member of a collective perceives a god or feels belief, he or she actually perceives the accumulated energy of on-going creation and maintenance of objects and ideas by members of a collective. Sacred objects, images, and ideas bear the trace of collective energy the more they are carefully crafted, maintained in spaces that are specially arranged, and written into behavioural codes. This reading of Durkheim allows us to consider him in a lineage of social constructivists and, particularly, in relation to Ludwik Fleck, who has been largely confined to different theoretical discussions when his contributions to sociology have been acknowledged at all. By reconsidering Durkheim, we have occasion to rethink his sociology and understand how he redrew the lines between thought and action, between epistemology and ontology, through the material framework of energy and force.     

Asking about the future: methodological insights from energy biographies

Temporality is fundamental to qualitative longitudinal (QLL) research, inherent in the design of returning to participants over time, often to explore moments of change. Previous research has indicated that talking about the future can be difficult, yet there has been insufficient discussion of methodological developments to address these challenges. This paper presents insights from the Energy Biographies project, which has taken a QLL and multimodal approach to investigating how everyday energy use can be understood in relation to biographical pasts and imagined futures. In particular, we detail innovative techniques developed within the project (e.g. SMS photograph activities) to elicit data on anticipated futures, in ways that engender thinking about participants’ own biographical futures and wider societal changes. We conclude by considering some of the significant benefits and challenges such techniques present. These methodological insights have a wider relevance beyond the substantive topic for those interested in eliciting data about futures in qualitative research.
