葡萄酒废水处理工艺研究

葡萄酒产业在我国发展很快,随着人们生活水平的提高,葡萄酒消费也在迅速增长,新疆作为我国的葡萄主产地,近些年来葡萄酒庄大量兴起,在葡萄酒生产繁盛的同时也会产生很多的废水,这些企业多位于城郊等偏远地区,周边缺少完备的排水设施,废水经处理后会直接排入自然环境或者用于绿化灌溉,因此要严格按照标准处理葡萄酒废水,达到排放要求,选取合适的废水处理工艺。

Clinical and economic benefits of extended treatment with apixaban for the treatment and prevention of recurrent venous thromboembolism in Canada

Background and objective Venous thromboembolism (VTE) is associated with long-term clinical and economic burden. Clinical guidelines generally recommend at least 3 months of anticoagulation, but, in clinical practice, concerns over bleeding risk often limit extended treatment. Apixaban was studied for extended VTE treatment in the AMPLIFY-EXT trial, demonstrating superiority to placebo in VTE reduction without increasing risk of major bleeding. This study assessed the long-term clinical and economic benefits of extending treatment with apixaban when clinical equipoise exists compared to standard of care with enoxaparin/warfarin and other novel oral anti-coagulants (NOACs) for the treatment and prevention of recurrent VTE in Canada.

Methods A Markov model was developed to follow patients with VTE over their lifetimes. Efficacy and safety for apixaban and enoxaparin/warfarin were based on AMPLIFY and AMPLIFY-EXT, while relative efficacy to other NOACs was synthesized by network meta-analysis (NMA). Dosages for NOACs and enoxaparin/warfarin were based on their respective trials and were given up to 18 months and up to 6 months, followed by no treatment, respectively. Patient quality adjusted life years (QALYs) were based on published studies, and costs for resource utilization were from a Ministry of Health perspective, expressed as 2014 CAD ($).

Results Extended treatment with apixaban compared to enoxaparin/warfarin resulted in fewer recurrent VTEs, VTE-related deaths, and bleeding events, but at slightly increased cost. The incremental cost-effectiveness ratio was $4828 per QALY gained. Compared to other NOACs, apixaban had the fewest bleeding events, similar recurrent VTE events, and the lowest overall cost, which was driven by the strong bleeding profile. In scenario analyses of acute and lifetime treatments, apixaban was cost-effective against all strategies.

Conclusions Extended treatment with apixaban can offer substantial clinical benefits and is a cost-effective alternative to enoxaparin/warfarin and other NOACs.     

耕地经济收益与耕地质量占补平衡探讨

耕地占补平衡与耕地的经济收益密切相关。耕地占补平衡不仅要考虑耕地质量的平衡,同时还要考虑耕地的收益平衡。本文将单位标准粮作为耕地占补平衡折算的中介,探讨了区域耕地质量占补平衡与耕地经济收益平衡联系。     

新疆银行信贷规模对于经济增长贡献实证分析

通过采集1990—2010年共21年来新疆各项贷款合计数据与GDP数据,运用回归分析模型和Granger因果检验,分析了信贷规模与GDP之间的关系。分析结果表明（：1）新疆信贷规模与GDP之间存在显著的关联关系;（2）信贷规模的短期波动对GDP有着显著的正影响,其弹性系数为1.19;（3）在短时期内,信贷是带动新疆GDP增长的原因之一,但长时期内,信贷规模与经济增长两者间不具有因果关系。     

工业经济效益评价研究——基于主成分分析和聚类分析

应用主成分分析法和聚类分析法对我国工业各行业的经济效益进行了评价,并将各行业企业单位数量作为对比变量,探讨其对各行业经济效益综合排名的影响。分析得出,行业企业单位数对行业经济效益排名有很大影响,但对行业聚类的影响不大。建议如下:应提高纺织业等工业行业的利润创造能力;对于企业单位数多而经济效益差的行业,要提高其行业准入门槛或加速兼并重组步伐。     

An economic evaluation of market development programmes for US dairy products

‘This study measured the effectiveness of US dairy export promotion programmes on increasing foreign demand and enhancing producers’ revenues. An import demand equation based on panel data was used to test whether export promotion has a positive and significant impact on US dairy exports. The effects of various promotion scenarios on the dairy market were then simulated, and benefit–cost ratios (BCRs) for these programmes were estimated. There were three key findings. First, the combined effort of public and private dairy export promotion expenditures had a positive and statistically significant impact on demand for US dairy products in the world market. The findings indicated that export promotion stimulated total dairy exports by 4.14 billion pounds, on average, per year, which represented 55.8% of total exports. Second, US dairy export promotion has been highly profitable for the nation’s dairy farmers. The calculated BCRs, based on assumed elasticity of supply, ranged from a low of 8.54 for the most elastic assumption to a high of 30.12. Third, from an optimality standpoint, dairy farmers are underinvesting in export promotion. The marginal BCRs ranged from a low of 3.79 to a high of 15.22, which means that, at the margin, increasing export promotion expenditures would be profitable for dairy farmers.     

林业专业合作社盈余利益分配标准的经济学分析

针对林业专业合作社利益分配问题,分析社员的利益分配行为和两种不同盈余利益分配标准造成的社员利益差异,揭示社员倾向于按出资额与交易量比例中较大的标准进行盈余利益分配,以获得更多的利益而承担更少的成本,提出完善合作社利益分配制度应当在内部契约上坚持以交易额分配为主,将出资额的合理利息界定为合作社成本,尽量保持社员出资额与交易额比例相一致,在配套制度上政府应当减少税费、扩大财政支持、加强教育引导与外部监督,以促进合作社健康发展。
