Cooperation Structure: The Growing Role of Independent Cooperation Networks

Existing cooperation on energy efficiency in East Asia involves a variety of organizations, from large multilateral institutions to small think-tanks and foundations. Cooperation mechanisms range from exchanges of experts and trainees, to the sharing of policy information at regional forums, to multi-million dollar technology installations. A variety of sectors have been targeted, from appliances to buildings to industry and electricity. Some cooperation efforts emphasize measurement of resulting energy savings, while others undertake less quantifiable routes to promoting energy conservation. Cooperation activity on energy efficiency has increased substantially over the past 10 to 15 years, yet those engaged in the cooperation emphasize that even more is needed. In this chapter, we identify existing energy efficiency cooperation activities in East Asia and examine the organizational structure of those activities. While cooperation on renewable energy, as well as projects under the Clean Development Mechanism, can contribute to a sustainable economy, energy security and environmental protection, only cooperation efforts focused on energy efficiency are analyzed here. Similarly, East Asian countries have engaged in cooperation on various aspects of energy security, but only activities aimed at energy efficiency are discussed here.1 Cooperation activities on energy efficiency and conservation are presented in four groups, based on the type of organizations that participate: 1. bilateral cooperation; 2. multilateral cooperation; 3. regional cooperation; and 4. independent international cooperation networks

Cooperation Targets: From Industry to Energy Services

Our research has identified three key trends in existing energy efficiency cooperation. The first, discussed in Chapter 3, is the growing role of independent, international cooperation networks in facilitating large-scale energy efficiency improvements. The second, explored in Chapter 4, is the increasing importance of policy development cooperation as an effective mechanism for promoting significant energy savings and greenhouse gas reductions. In Chapter 5, we examine cooperation activity sector by sector and note increasing activity in certain economic sectors with numerous, diverse actors, most notably in appliances, transportation and buildings. In the industrial sector, there is a trend from “hard” technology cooperation (e.g., technology transfer) to “soft” cooperation involving capacity building and policy tools such as voluntary agreements and energy management systems

Implementing the Minamata Convention on Mercury: Will China Deliver?

China has undertaken a major shift in its position on mercury as an environmental problem over the last decade and a half. It ratified the Minamata Convention (MC) in 2016 and by doing so has committed to implement the treaty objectives. This article asks: How do we explain China’s will and ability to implement its MC obligations? There is little systematic knowledge about the main factors underlying implementation of international mercury objectives in China, hence this article contributes new research on this important topic. We examine the implementation process, focusing on the coal sector and differentiate between indirect effects from other policies and direct efforts to implement obligations. We find that China has moved toward stricter regulation of mercury emissions and direct implementation of the Minamata Convention in the coal sector. However, our study shows that local implementation capacity needs improvement.Implementing the Minamata Convention on Mercury: Will China Deliver?acceptedVersio

Sofosbuvir based treatment of chronic hepatitis C genotype 3 infections-A Scandinavian real-life study

Background and aims Chronic hepatitis C virus (HCV) genotype 3 infection with advanced liver disease has emerged as the most challenging to treat. We retrospectively assessed the treatment outcome of sofosbuvir (SOF) based regimes for treatment of HCV genotype 3 infections in a real life setting in Scandinavia. Methods Consecutive patients with chronic HCV genotype 3 infection were enrolled at 16 treatment centers in Denmark, Sweden, Norway and Finland. Patients who had received a SOF containing regimen were included. The fibrosis stage was evaluated by liver biopsy or transient liver elastography. The following treatments were given according availability and local guidelines: 1) SOF + ribavirin (RBV) for 24 weeks, 2) SOF + daclatasvir (DCV) +/-RBV for 12-24 weeks, 3) SOF + pegylated interferon alpha (peg-IFN-a) + RBV for 12 weeks or 4) SOF/ledipasvir (LDV) + RBV for 12-16 weeks. The primary endpoint was sustained virological response (SVR) assessed at week 12 (SVR12) after end of treatment. Results We included 316 patients with a mean age of 55 years (range 24-79), 70% men, 49% treatment experienced, 58% with compensated cirrhosis and 12% with decompensated cirrhosis. In the modified intention to treat (mITT) population SVR12 was achieved in 284/311 91%) patients. Among 26 treatment failures, five had non-response, 3 breakthrough and 18 relapse. Five patients were not included in the mITT population. Three patients died from reasons unrelated to treatment and two were lost to follow-up. The SVR12 rate was similar for all treatment regimens, but lower in men (p = 0.042), and in patients with decompensated liver disease (p = 0.004). Conclusion We found that sofosbuvir based treatment in a real-life setting could offer SVR rates exceeding 90% in patients with HCV genotype 3 infection and advanced liver disease.Peer reviewe

Ideology and moral values in rhetorical framing:How wine was saved from the 19th Century Phylloxera Epidemic

Extant organizational research into crises has focused on the efforts of different actors to defend and legitimate their ideologies towards particular actions. Although insightful, such research has offered little knowledge about the moral reasoning underlying such action. In this paper, we explore how moral reasoning from different ideological viewpoints can lead to polarized debates and stalemate within the context of ecological crises. We apply our conceptual framework in an analysis of the 19th century French phylloxera epidemic. Drawing upon this analysis, we argue that, by adapting their moral reasoning, opposing stakeholder groups could maintain their underlying ideology, while at the same time pragmatically changing their actions towards the crisis. We discuss the theoretical implications of our analysis for historical research in organizational studies and research on organizations and the natural environment

Novel 3D Pixel Sensors for the Upgrade of the ATLAS Inner Tracker

The ATLAS experiment will undergo a full replacement of its inner detector to face the challenges posed by the High Luminosity upgrade of the Large Hadron Collider (HL-LHC). The new Inner Tracker (ITk) will have to deal with extreme particle fluences. Due to its superior radiation hardness the 3D silicon sensor technology has been chosen to instrument the innermost pixel layer of ITk, which is the most exposed to radiation damage. Three foundries (CNM, FBK, and SINTEF), have developed and fabricated novel 3D pixel sensors to meet the specifications of the new ITk pixel detector. These are produced in a single-side technology on either Silicon On Insulator (SOI) or Silicon on Silicon (Si-on-Si) bonded wafers by etching both n- and p-type columns from the same side. With respect to previous generations of 3D sensors they feature thinner active substrates and smaller pixel cells of 50 × 50 and 25 × 100 µm2. This paper reviews the main design and technological issues of these novel 3D sensors, and presents their characterization before and after exposure to large radiation doses close to the one expected for the innermost layer of ITk. The performance of pixel modules, where the sensors are interconnected to the recently developed RD53A chip prototype for HL-LHC, has been investigated in the laboratory and at beam tests. The results of these measurements demonstrate the excellent radiation hardness of this new generation of 3D pixel sensors that enabled the project to proceed with the pre-production for the ITk tracker.publishedVersio

Feedforward and recurrent inhibitory receptive fields of principal cells in the cat’s dorsal lateral geniculate nucleus

Principal cells in the dorsal lateral geniculate nucleus receive both feedforward and recurrent inhibition. Despite many years of study, the receptive field structure of these inhibitory mechanisms has not been determined. Here, we have used intracellular recordings in vivo to differentiate between the two types of inhibition and map their respective receptive fields. The feedforward inhibition of a principal cell originates from the same type of retinal ganglion cells as its excitation, while the recurrent inhibition is provided by both on- and off-centre cells. Both inhibitory effects are strongest at the centre of the excitatory receptive field. The diameter of the feedforward inhibitory field is two times larger, and the recurrent two to four times larger than the excitatory field centre. The inhibitory circuitry is similar for X and Y principal cells

Anodal Transcranial Direct Current Stimulation Reduces Psychophysically Measured Surround Suppression in the Human Visual Cortex

Transcranial direct current stimulation (tDCS) is a safe, non-invasive technique for transiently modulating the balance of excitation and inhibition within the human brain. It has been reported that anodal tDCS can reduce both GABA mediated inhibition and GABA concentration within the human motor cortex. As GABA mediated inhibition is thought to be a key modulator of plasticity within the adult brain, these findings have broad implications for the future use of tDCS. It is important, therefore, to establish whether tDCS can exert similar effects within non-motor brain areas. The aim of this study was to assess whether anodal tDCS could reduce inhibitory interactions within the human visual cortex. Psychophysical measures of surround suppression were used as an index of inhibition within V1. Overlay suppression, which is thought to originate within the lateral geniculate nucleus (LGN), was also measured as a control. Anodal stimulation of the occipital poles significantly reduced psychophysical surround suppression, but had no effect on overlay suppression. This effect was specific to anodal stimulation as cathodal stimulation had no effect on either measure. These psychophysical results provide the first evidence for tDCS-induced reductions of intracortical inhibition within the human visual cortex

Context Matters: The Illusive Simplicity of Macaque V1 Receptive Fields

Even in V1, where neurons have well characterized classical receptive fields (CRFs), it has been difficult to deduce which features of natural scenes stimuli they actually respond to. Forward models based upon CRF stimuli have had limited success in predicting the response of V1 neurons to natural scenes. As natural scenes exhibit complex spatial and temporal correlations, this could be due to surround effects that modulate the sensitivity of the CRF. Here, instead of attempting a forward model, we quantify the importance of the natural scenes surround for awake macaque monkeys by modeling it non-parametrically. We also quantify the influence of two forms of trial to trial variability. The first is related to the neuron’s own spike history. The second is related to ongoing mean field population activity reflected by the local field potential (LFP). We find that the surround produces strong temporal modulations in the firing rate that can be both suppressive and facilitative. Further, the LFP is found to induce a precise timing in spikes, which tend to be temporally localized on sharp LFP transients in the gamma frequency range. Using the pseudo R[superscript 2] as a measure of model fit, we find that during natural scene viewing the CRF dominates, accounting for 60% of the fit, but that taken collectively the surround, spike history and LFP are almost as important, accounting for 40%. However, overall only a small proportion of V1 spiking statistics could be explained (R[superscript 2]~5%), even when the full stimulus, spike history and LFP were taken into account. This suggests that under natural scene conditions, the dominant influence on V1 neurons is not the stimulus, nor the mean field dynamics of the LFP, but the complex, incoherent dynamics of the network in which neurons are embedded.National Institutes of Health (U.S.) (K25 NS052422-02)National Institutes of Health (U.S.) (DP1 ODOO3646
