国际标准化与工程适用性

研究认为、标准的发展与工程密切相关，关键的因素是工程与技术的协调一致性、即工程适用性。工程的需要是标准制定的基础，工程中新技术的使用也促进标准技术的进步；而标准与标准化可以对工程技术进行优化．促进工程最大效益的实现。     

英、德、美、日的塑料包装回收

英国 根据英国法律文件“生产者责任和义务（包装废弃物）”，各包装生产者及使用者都必须达到预定的回收利用率。根据该法规，各企业必须遵守三个主要法规：1．注册登记，包括所需的相关包装数据；2．回收率和循环率；3．证书。     

传统能源及碳交易价格与新能源股价——基于VAR和CAPM-GARCH模型的分析

文章构建VAR模型和CAPM-GARCH模型,分析检验了2010年7月初至2013年底期间传统能源和碳排放权交易价格对国内新能源上市公司股价波动的影响及新能源股票收益率的波动特点,研究发现:国内煤价对新能源公司股价有显著的正向影响,而国际油价的影响不显著;碳排放权交易价格也是引起新能源投资价值从而上市公司股价变动的重要因素;新能源公司股价指数对高科技股价指数并不敏感,反映出国内新能源上市公司科技含量不足,资本市场关注更多的是新能源的概念而非技术优势;国内新能源股票整体的系统风险在1.125~1.131之间,利好消息比利空消息能引起新能源股票收益率更大的波动。

Does Medical Equipment Expansion Lead to More Diagnostic Services? Evidence from China’s Sichuan Province

A major goal of China’s healthcare reform is to control the increasing healthcare spending, much of which can be attributed to the overuse of diagnostic tests and has been relatively less studied in the literature. This article analyzes the correlation between medical equipment expansion and the increase in diagnostic test expenditure in China, using Sichuan Province as an example. County-level data aggregated from hospitals’ annual reports in Sichuan Province from 2008 to 2012 were used. The results show a positive correlation between the expansion of medical equipment and the increase in diagnostic test expenditure. Our study provides implications on reforming China’s healthcare delivery system and medical equipment regulation policies.     

均衡视角下集体化转型对中小企业劳动关系的影响研究

当前我国劳动关系出现集体化新趋势,这必将对中小企业劳动关系产生深远影响。为适应新趋势,中小企业首先要进一步规范个别劳动关系,并在此基础上逐步构建适合中小企业特点的集体劳动关系,同时要在理念、方式和机制上进行变革。     

斗轮堆取料机斗轮轴轴承密封装置

斗轮堆取料机斗轮轴轴承密封圈工作环境恶劣,腐蚀性粉尘颗粒积聚严重,导致密封圈过早磨损失效,进而导致轴承磨损报废。对此,设计新型密封装置,减少甚至消除粉尘的入侵,保证轴承正常工作。在改进后对密封装置进行了验证,实践证明,该装置能有效解决油封和轴承的防尘、防腐蚀等问题,提升了油封和轴承的使用寿命,降低维保成本。     

传统型美术专业在应用型本科院校中的生存与发展

传统型美术专业是否真的具有培养应用型人才的能力，是值得思考的问题。大众化教育是我国高等教育的新局面，但应用型本科院校中的传统美术专业却逐渐变为冷门。课程改革的迟缓、生源数量的减少、校地合作的局限性等问题，一直困扰着传统型美术专业。如何能够向应用型教育模式转变，是扭转此番尴尬局面的关键。     

Cost-effectiveness analysis of ramucirumab treatment for patients with hepatocellular carcinoma who progressed on sorafenib with α-fetoprotein concentrations of at least 400 ng/ml

Abstract

Objective: This study aimed to compare the cost-effectiveness of ramucirumab versus placebo for patients with hepatocellular carcinoma who progressed on sorafenib with α-fetoprotein concentrations (AFP) of at least 400?ng/ml in the United States.

Methods: A Markov model was constructed to assess the cost-effectiveness of ramucirumab. Health outcomes were measured as quality-adjusted life years (QALYs). With TreeAge software, the disease process was modeled as three health states: progression-free survival (PFS), progressive disease (PD), and death. Costs were extracted from the REACH-2 trial, and utility was derived from published literature. Incremental cost-effectiveness ratios (ICERs) were calculated to compare ramucirumab with placebo. Probabilistic sensitivity analyses were developed to examine the robustness of the results.

Results: In the base case analysis, ramucirumab therapy had a cost of $55,508.41 and generated 0.54 QALYs, while placebo therapy had a cost of $761.09 and generated 0.47 QALYs, leading to an additional $54,747.32 in costs and 0.07 QALYs. The ICER was $782,104.57 per QALY, which was much higher than the willingness-to-pay threshold of $100,000 per QALY. According to sensitivity analyses, the utility of PD in the two groups was the dominant parameter influencing the ICER.

Conclusion: Although ramucirumab was associated with prolonged survival for patients with advanced hepatocellular carcinoma who progressed on sorafenib treatment with an AFP of at least 400?ng/ml, it is not a cost-effective treatment from a United States payer perspective.     

Foreign Ownership Restriction and Momentum – Evidence from Emerging Markets

This study investigates the impact of foreign investors on stock price efficiency and return predictability in emerging markets. It finds that stocks fully investible for foreign investors exhibit stronger price momentum than non‐investible stocks. The difference in momentum effects between stocks with different levels of investibility cannot be fully explained by world market risk, size, turnover, or country‐specific factors. Further tests show that fully investible stocks have no post‐earnings‐announcement drift (PEAD), and their short‐term momentum reverses over a longer horizon. These results show that the stronger momentum of highly investible stocks does not appear to be driven by foreign investors' underreaction to firm‐specific information, but is more likely to be generated by their positive feedback trading.
