Geothermal energy utilization trends from a technological paradigm perspective

The use of geothermal energy and its associated technologies has been increasing worldwide. However, there has been little paradigmatic research conducted in this area. This paper proposes a systematic methodology to research the development trends for the sustainable development of geothermal energy. A novel data analysis system was created to research the geothermal energy utilization trends, and a technological paradigm theory was adopted to explain the technological changes. A diffusion velocity model was used to simulate and forecast the geothermal power generation development in the diffusion phase. Simulation results showed that the development of installed capacity for geothermal generation had a strong inertia force along with the S-curve. Power generation from geothermal power sources reached a peak in 2008 and is estimated to be saturated by 2030. Geothermal energy technologies in hybrid power systems based on other renewable energy sources look to be more promising in the future.

The Locus of Redundant-Targets and Nontargets Effects: Evidence From the Psychological Refractory Period Paradigm.

In target detection tasks, responses are faster when displays have 2 targets (redundant-targets effect; RTE) and slower when they have no targets (nontargets effect; NTE) relative to displays with a single target. The psychological refractory period paradigm was used to localize these effects. In Experiment 1, participants classified tones as high or low and then classified letters as targets or nontargets after a short or long stimulus onset asynchrony (SOA). The magnitudes of the RTE and NTE did not depend on SOA. In Experiment 2, the order of the tasks was reversed, and at short SOAs the RTE and NTE had similar magnitudes for both tone discrimination and target detection responses. These findings suggest that the RTE and NTE arise during response selection. Interactive effects of tone pitch with the number and type of target features were also observed, and these were tentatively interpreted as synesthetic effects.

From product-oriented to process-oriented: Emerging new engineering paradigm

The conventional approach has put emphasis upon reducing labour, and increasing efficiency and uniformity. But this holds good only in the mass production paradigm. As we are entering the age of small production with far wider varieties, these principles of yesterday should be re-examined. Labour itself sometimes gives satisfaction if it involves the joy of creation, and longer time does not necessarily mean just patience, it sometimes turns into expectation if greater joy will be provided later. Too much fitness for the purpose sometimes means lack of robustness and adaptability to the quickly and widely changing environment. Thus, we should reconsider the items we thought important in the mass production age to aptly cope with the diversification of each customer’s requirements.     

Automatic processing of psychological distance: Evidence from a Stroop task.

A picture-word version of the Stroop task was used to test the automatic activation of psychological distance by words carrying various senses of psychological distance: temporal (tomorrow, in a year), social (friend, enemy), and hypotheticality (sure, maybe). The pictures implied depth, with the words appearing relatively close to or distant from the observer. The participants classified the spatial distance of words faster when the word's implicit psychological distance matched its spatial distance (e.g., a geographically close word was classified faster when it was "friend" than when it was "enemy"). The findings are consistent with the idea that psychological distance is accessed automatically, even when it is not directly related to people's current goals, and suggest that psychological distance is an important dimension of meaning, common to spatial distance, temporal distance, social distance, and hypotheticality.

基于负载预测的微服务混合自动扩展

由于边缘云没有比中心云更强大的计算处理能力,在应对动态负载时很容易导致无意义的扩展抖动或资源处理能力不足的问题,所以在一个真实的边缘云环境中对微服务应用程序使用两个合成和两个实际工作负载进行实验评估,并提出了一种基于负载预测的混合自动扩展方法（predictively horizontal and vertical pod autoscaling,Pre-HVPA）。该方法首先采用机器学习对负载数据特征进行预测,并获得最终负载预测结果。然后利用预测负载进行水平和垂直的混合自动扩展。仿真结果表明,基于该方法所进行自动扩展可以减少扩展抖动和容器使用数量,所以适用于边缘云环境中的微服务应用。     

Evolutionary digital twin: A new approach for intelligent industrial product development

To fulfill increasingly difficult and demanding tasks in the ever-changing complex world, intelligent industrial products are to be developed with higher flexibility and adaptability. Digital twin (DT) brings about a possible means, due to its ability to provide candidate behavior adjustments based on received “feedbacks” from its physical part. However, such candidate adjustments are deterministic, and thus lack of flexibility and adaptability. To address such problem, in this paper an extended concept – evolutionary digital twin (EDT) and an EDT-based new mode for intelligent industrial product development has been proposed. With our proposed EDT, a more precise approximated model of the physical world could be established through supervised learning, based on which the collaborative exploration for optimal policies via parallel simulation in multiple cyberspaces could be performed through reinforcement learning. Hence, more flexibility and adaptability could be brought to industrial products through machine learning (such as supervised learning and reinforcement learning) based self-evolution. As a primary verification of the effectiveness of our proposed approach, a case study has been carried out. The experimental results have well confirmed the effectiveness of our EDT based development mode.     

主导社会范式变化的环境社会学分析

主导社会范式是变化的,而对它的变化原因的探讨很少,从环境社会学角度的分析就更少了。本文主要从主导社会范式的变化角度,通过对其变化的环境原因的思考,进行了广泛的环境社会学分析。得出了主导社会范式的变化主要是由环境的变化以及人们对这种环境变化做出以人为中心的反映而引起的,并在社会中有较为广泛的表现。体现在人们对社会的发展模式的争论上。启示人们要重视环境的变化对人类社会发展的重要影响。同时也要求人们在提出发展模式时要充分考虑到人与环境的协调发展。     

从方法论视角解读“乡村治理”研究——兼评《江苏乡村治理发展报告2013》

结合刘祖云教授所著的《江苏乡村治理发展报告》,从方法论视角全面解读中国乡村治理的研究概貌。在研究定位上,经历从"村落"到"乡域"的拓展;在研究范式上,超越"村落社区"的观察视角不断被探索;在研究方法上,主要采用"田野调查"与"个案深描";在研究理路上,主要遵循"个别到一般"逻辑脉络;在研究走向上,应努力建立起中国乡村治理研究的本土化理论体系。
