基于能耗的碳排放研究

粗放式经济的发展导致高强度的碳排放,面对全球气候变化的严峻形势,低碳经济给出了一条可持续的发展之路。我国是一个人口大国,经济发展规模较大加上经济结构不合理,导致能耗高、碳排放强度大,为了减少碳排放,应对气候变暖的危机,我们必须走低碳经济之路,国家要开征碳税,引导合理的能源消费,由粗放型经济向集约型的低碳经济转变,调整产业结构,优化能源消费结构,提高能源的最终利用效率,从而达到经济效益和环境效益的＂双赢＂。     

Investigating Ministry Names for Comparative Policy Analysis: Lessons from Energy Governance

This commentary contends that ministry names offer a valuable construct for furthering the state of comparative policy analysis. Using energy governance as an example, this study shows that ministries’ names are stable in some countries but subject to changes in others. Furthermore, there is variation in the ministries’ names over time. Creating or maintaining a ministry that explicitly mentions “energy” is interpreted as signaling enhanced political attention to this issue, whereas removing the referral to “energy” signals the opposite. The names of ministries responsible for energy matters also affect energy policy outputs. Drawing on 43 OECD and BRICS countries, the empirical analysis shows that countries which have ministries in place that mention “energy” together with “economy” in their names are swifter in adopting renewable energy targets. Ministries that mention “economy” along with “climate” and/or “environment” also have an inclination to be faster in adopting such targets, but the coefficients fail to reach conventional levels of statistical significance. Given this finding, it appears worth pursuing this line of research further.     

Congressional Attention and Opportunity Structures: The Select Energy Independence and Global Warming Committee

This article examines the role that overlapping committee jurisdictions play in fostering or hindering attention to environmental and energy issues in the U.S. Congress. The Select Energy Independence and Global Warming Committee, created by House Democrats in 2007 , and its chairman Rep. Ed Markey took advantage of opportunities within the existing jurisdictional arrangement to increase attention to these issues despite lacking any legislative authority. Data from the 110th and 111th Congresses show that the Select Committee held more hearings on climate change and alternative energy, and on environmental and energy policy generally, than any other committee. The committee also increased the range of sources informing debate on these issues by calling different witnesses than other committees. These findings have important implications for the relationship between institutional structure and agendas and for Congress' policy‐making role on energy and the environment.     

Identifying the Causes of Issue Attention and Policy Change: Evidence from U.S. Offshore Oil and Natural Gas Drilling Policy, 2008

The flow of attention in the policy process is dynamic and disruptive. While we know changes in issue attention often result in policy change, the causal mechanisms underlying the different stages of the attention allocation process remain unclear. This article uses Punctuated Equilibrium Theory to examine an underdeveloped aspect of issue attention within policy‐making institutions: how specific policy indicators influence the entry and exit of issues on policy‐making agendas. Partisan issue attention in the House of Representatives is used to analyze a significant change to U.S. offshore oil and natural gas drilling policy in 2008. The results highlight how historically high gasoline prices precipitated a shift in attention to offshore drilling and subsequent policy change. Moreover, gasoline prices Granger‐cause attention to energy policy in partisan speeches over time. The analysis further reveals how competing policy frames and a salient focusing event shaped congressional and public discourse, leading to subsequent changes in attention. Taken together, the findings broaden our understanding of the policy process by identifying the specific forces behind the entry and exit of issues on the policy‐making agenda.     

The Space Between: Demonization of Opponents and Policy Divergence

Prior research on policy conflicts indicates a tendency among policy actors to misperceive the influence of actors engaged in policy debates based on the degree of distance between their relative policy positions. This research develops a measure for assessing the degree and direction of the misperception effect. This measure is then utilized as a dependent variable to assess the relationship between theoretically relevant factors and the degree to which actors will exaggerate the influence of their opponents and allies. The research uses original survey data of policy actors engaged in the debate over hydraulic fracturing in New York. The results indicate misperceptions of relative influence are prevalent and most associated with the experience of a policy loss and holding relatively extreme policy beliefs. The findings provide new insight into factors that influence the demonization of political opponents. These insights are timely in the context of polarized debates over environmental and energy policy in the United States.

加减薯蓣丸治疗轻中度肾精亏虚证老年期痴呆的磁共振波谱研究

目的 采用氢质子磁共振波谱（1H magnetic resonance spectroscopy,1H MRS）检查结合神经心理学量表的方法,评价加减薯蓣丸对老年期痴呆患者的治疗效果。方法 收集2015年12月至2017年4月湖北省中医院脑病科及老年病科的血管性痴呆（vascular dementia,VD）及阿尔茨海默病（Alzheimers disease,AD）肾精亏虚证患者各20例,另选认知功能正常者20例作为对照组。入选老年期痴呆患者在内科治疗的基础上予以加减薯蓣丸治疗。对老年期痴呆患者治疗前后及对照组受试者进行简易精神状态评价量表（mini mental state examination,MMSE）、日常生活能力量表（activities of daily living,ADL）、痴呆证候分型量表（syndromes differentiation scale for dementia,SDSD）评估及1H MRS检查。结果 加减薯蓣丸显著升高VD及AD患者降低的MMSE评分（P＜0.05）,降低其升高的SDSD评分（P＜0.05）,但对ADL评分的改善作用无统计学意义（P＞0.05）。1H MRS检查表明,加减薯蓣丸显著升高VD和AD患者双侧额叶下降的N 乙酰天门冬氨酸（N aspart acetyl,NAA）/肌酸（creatine,Cr）水平（P＜0.05）,而降低双侧额叶升高的胆碱复合物（choline,Cho）/Cr作用无统计学意义（P＞0.05）。加减薯蓣丸对VD患者和AD患者MMSE、SDSD、ADL评分和双侧额叶NAA/Cr、Cho/Cr的作用差异无统计学意义（P＞0.05）。结论 加减薯蓣丸改善轻中度老年期痴呆患者认知功能的机制可能与促进损伤的神经细胞修复有关。     

Multiple Streams in Hawaii: How the Aloha State Adopted a 100% Renewable Portfolio Standard

Renewable portfolio standards (RPS) are an important policy tool for reducing carbon emissions and advancing the global shift toward renewable energy. As the U.S. federal government backs away from commitments to reduce greenhouse gas emissions, subnational governments play an increasingly important role in mitigating climate change. In June 2015, Hawaii became the first state in the United States to adopt a 100% RPS. Through understanding the conditions that gave rise to Hawaii’s RPS, policy actors will be better informed as they navigate policy processes in other states and jurisdictions. This study uses Kingdon’s Multiple Streams Framework (MSF) to explore the policy process that led to Hawaii’s 100% RPS. Data were collected during the summer of 2016 via interviews with 25 key policy actors and informants in Hawaii. Expectations based on the MSF are confirmed, and the results suggest factors that might be included or explored in future studies of RPS adoption.     

Fabrication of compound nonwoven materials for soft body armor

The primary objective of body armor research is the development of low-cost, lightweight, wearable garments that effectively resist ballistic impact. This study introduces a material intended to reduce nonpenetration trauma by absorbing energy from ballistic impacts. Layers of web were made by low-melting point polyester (LMPET) on unaligned fibers of high-strength polyamide 6 (HSPA6). A compound nonwoven fabric was made by laying high-strength Vectran filaments between two layers of HSPA6-LMPET web. The new fabric underwent needle punching and thermal bonding to form a composite sandwich structure. The new fabric was subjected to a falling weight impact test and a ballistic impact test. The results indicated that the material with the new design reduced maximum indentation depth by 8%. Furthermore, soft body armor made from the material with the new design would cost less to produce and would weigh 22.5% less than conventional soft body armor.
