中庸思维与大学生网络成瘾:同伴冲突和性别的作用

本研究基于资源保存理论和社会角色理论,选取武汉市492名大学生为被试,以问卷方式测量了大学生中庸思维、同伴冲突以及网络成瘾。结果显示：（1）中庸思维与同伴冲突、网络成瘾呈显著负相关;同伴冲突与网络成瘾呈显著正相关;（2）同伴冲突在中庸思维与网络成瘾的关系之中起中介作用;（3）性别对中介路径“中庸思维→同伴冲突→网络成瘾”的前半段路径有显著的调节效应。对于男性,中庸思维可以负向预测同伴冲突;对于女性,中庸思维不能预测同伴冲突。本研究的结果表明,同伴冲突中介中庸思维与网络成瘾的关系;但是,中庸思维与同伴冲突的负向联系只存在于男性之中。     

Energy management solutions in the Internet of Things applications: Technical analysis and new research directions

By advancement of Internet of Things (IoT) technology in smart life such as smart city, smart home, smart healthcare and smart transportation, interconnections between smart things are growing that complicate evaluation of efficiency factors on the intelligent systems. Energy consumption as one of the most challenging issues is increasing with the growing IoT devices and existing interconnections between cloud data centers, mobile applications and human activities. Managing energy efficiency and power consumption is one of the important issues in green IoT-enabled technologies. This paper presents an overview on the energy management solutions in the IoT based on Systematic Literature Review (SLR). The main goal of this SLR-based overview is to recognize significant research trends in the field of energy management and power consumption techniques which need additional consideration to highlight more efficient and effective methods in IoT. Also, a taxonomy is proposed to categorize the existing research studies on energy management solutions. A statistical and technical analysis of reviewed existing papers are provided, and evaluation factors and attributes are discussed. We observed that variety of published research papers in smart home have highest percentage to evaluate energy management in the IoT. Also, deep learning and clustering methods are must popular techniques that were applied to evaluate the energy management in IoT case studies. Finally, new challenges and forthcoming issues of the energy management and efficient power consumption methods are presented.     

Colorado’s Fracking Debates: Citizen Science,Conflict and Collaboration

Technological advancements in hydraulic fracturing and horizontal drilling have spurred a controversial boom in oil and gas production. In Colorado, these debates take place directly in the suburban metro corridor, where local governments are turning to memorandums of understanding (MOU), negotiated directly with industry operators, to shape industry activity. We show that in Erie, the town that first pioneered this policy tool, these MOUs ostensibly welcome public participation in the planning and deliberation process but can unintentionally reinforce scientism-based governance. Citizen science challenged the local government’s deficit model of the public, but it also shored up scientific authority and triggered a government imaginary of anti-fracking activists as an unruly public. Residents countered this imaginary by electing officials committed to public engagement and transparency, which opened up debates to encompass quality of life issues that had been sidelined by the original focus on competing scientific evidence about pollution. While fracking-related citizen science does not appear to be directly responsible for the government turnover and its attendant shift in governance, we suggest it did enhance civic engagement related to general issues of fiscal responsibility, ethics and transparency that did play a role in the election.     

The Energy Walk: Experimenting with Aesthetic Methods in STS?

Abstract

In 2014 the research group Alien Energy, based at the IT University of Copenhagen, performed an experiment into the potential of creative intervention as an ethnographic method, in researching the development of new energy forms, such as wave- and geothermal energy. To this end the Energy Walk was created: a carefully choreographed and digitally guided audio walk leading the participant around the harbour area of the Danish town Hanstholm, whilst telling stories of energy and infrastructures. In this paper I argue, that the walk manoeuvres a layered landscape of energetic and infrastructural visibility and invisibility, hereby sensitizing the participant to the manifold energy forms constantly present in our daily lives. Drawing on the aesthetic philosophy of John Dewey I argue, that in doing so, the walk effectively facilitates what he calls an aesthetic experience, and suggest that the walk might best be understood in terms of aesthetic experimentation as a relevant method in STS research.     

先秦诸子学说对中国现代能源资源战略的启示

当代中国在经济发展的压力之下,用牺牲自然资源来获取经济增长,这无疑是最简捷的途径,但资源的有限性则约束了利用资源的质量、数量以及时空范围。中国先秦时代,诸子百家的许多论断就闪现了对资源合理利用的认识,用这些理念反观当今科学发展观视角下的能源资源战略,仍具有鲜明的借鉴意义和历史价值。     

On the nature of sustainable Economic systems

The theme of the 1982 Tokyo Conference of the Club of Rome is ‘Approaching the 21st Century: Global Problems and Human Choices.’ This is a topic of crucial importance that our generations will have to tackle in all its breadth and depth. Within its context are presented some ideas about the alternatives of the human future.     

Quantum Paradoxes, Time, and Derivation of Thermodynamic Law: Opportunities from Change of Energy Paradigm

Summary  Well known quantum and time paradoxes, and the difficulty to derive the second law of thermodynamics, are proposed to be the result of our historically grown paradigm for energy: it is just there, the capacity to do work, not directly related to change. When the asymmetric nature of energy is considered, as well as the involvement of energy turnover in any change, so that energy can be understood as fundamentally “dynamic”, and time-oriented (new paradigm), these paradoxes and problems dissolve. The most basic consequence concerns the particle-wave dualism. For a reversible inter-conversion of a particle into a wave, subject to a dynamic energy, a self-image of information has to be generated: quantum theory has to be complemented by a theory of information. Then, quantum processes can be derived from classical ones and the second law of thermodynamics with the tendency of increasing entropy follows in a straightforward way.     

The effect of exercise intensity on joint power and dynamics in ergometer double-poling performed by cross-country skiers

The purpose of this study was to examine the effect of increasing exercise intensity on the role of joint powers in ergometer double poling (DP), while taking specific dynamic constraints into account. One main question was whether lower-body power contribution increased or decreased with increasing intensity. Nine male Norwegian national-level cross-country skiers performed ergometer DP at low, moderate, high and maximal intensity. Kinematics, and ground (GRF) and poling (F_poling) reaction forces were recorded and used in link segment modeling to obtain joint and whole-body dynamics. Joint powers were averaged over the cycle, the poling (PP) and recovery (RP) phases. The contribution of these average powers was their ratios to cycle average poling power. At all intensities, the shoulder (in PP) and hip (mostly in RP) generated most power. Averaged over the cycle, lower-body contribution (sum of ankle, knee and hip power) increased from ∼37% at low to ∼54% at maximal intensity (p < .001), originating mostly from increased hip contribution within PP, not RP. The generation of larger F_poling at higher intensities demanded a reversal of hip and knee moment. This was necessary to appropriately direct the GRF vector as required to balance the moment about center of mass generated by F_poling (control of angular momentum). This was reflected in that the hip changed from mostly absorbing to generating power in PP at lower and higher intensities, respectively. Our data indicate that power-transfer rather than stretch-shortening mechanisms may occur in/between the shoulder and elbow during PP. For the lower extremities, stretch-shortening mechanisms may occur in hip, knee and trunk extensors, ensuring energy conservation or force potentiation during the countermovement-like transition from body lowering to heightening. In DP locomotion, increasing intensity and power output is achieved by increased lower-body contribution. This is, at least in ergometer DP, partly due to changes in joint dynamics in how to handle dynamic constraints at different intensities.
