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. 相似文献

AbstractIn 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. 相似文献

The term third-wave cognitive behavioral therapy (CBT) encompasses new forms of CBT that both extend and innovate within CBT. Most third-wave therapies have been subject to randomized controlled trials (RCTs) focused on clinical effectiveness; however, the number and quality of economic evaluations in these RCTs has been unknown and may be few. Evidence about efficiency of these therapies may help support decisions on efficient allocation of resources in health policies. The main aim of this study was to systematically review the economic impact of third-wave therapies in the treatment of patients with physical or mental conditions. We conducted a systematic literature search in PubMed, PsycINFO, EMBASE, and CINALH to identify economic evaluations of third-wave therapies. Quality and Risk of Bias (RoB) assessment of economic evaluations was also made using the Drummond 35-item checklist and the Cochrane Collaboration’s tool for assessing risk of bias, respectively. Eleven RCTs were included in this systematic review. Mindfulness-Based Cognitive Therapy (MBCT), Mindfulness-Based Stress Reduction (MBSR), Acceptance and Commitment Therapy (ACT), Dialectical Behavior Therapy (DBT), and extended Behaviour Activation (eBA) showed acceptable cost-effectiveness and cost-utility ratios. No study employed a time horizon of more than 3 years. Quality and RoB assessments highlight some limitations that temper the findings. There is some evidence that MBCT, MBSR, ACT, DBT, and eBA are efficient from a societal or a third-party payer perspective. No economic analysis was found for many third-wave therapies. Therefore, more economic evaluations with high methodological quality are needed. 相似文献

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。 相似文献

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. 相似文献

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. 相似文献

In this paper we introduce and investigate the capacity for a novel, technologically advanced system (goACT) to enhance face-to-face psychotherapy. Specifically, we explore the capacity for goACT to enhance therapeutic alliance (TA) and engagement, and reduce distress. Using a mixed-methods, multiple-baseline design we present the first study to examine the utility, effectiveness and user experience of goACT in a university psychology clinic setting. The introduction of between-session goACT use was staggered across patients (N = 7). Patients completed weekly measures of mood, patient-rated TA and clinician-rated engagement. Semi-structured interviews were used to qualitatively understand user experience of the system. Methodological limitations impacted the generalisability of multiple-baseline findings, yet qualitative results provide a significant contribution to the literature and groundwork upon which further study can be built. Results indicated that goACT built engagement and TA via novel change processes that were associated with expanding the parameters of the therapeutic encounter beyond the one-hour session. Change processes that underpin the qualitative success of goACT are discussed in terms of their theoretical implications. goACT is likely to be a useful tool for enhancing the quality and quantity of traditional face-to-face psychotherapy. 相似文献

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 (Fpoling) 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 Fpoling 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 Fpoling (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. 相似文献
