    The Game for Implementing Safety Investment Guarantee System in Coal Enterprises

    No full text
    通过建立政府、保险公司、同业协会与煤炭企业安全投资行为,以及煤炭企业安全管理与煤炭企业员工之间的博弈模型,并对其均衡结果进行分析,论证了政府、保险公司、同业协会、企业员工与煤炭企业安全投资行为之间的制约性和保障性,为构建煤炭企业安全投资保障机制提供了理论依据。This paper analyzes the equilibrium of a game among the government, insurance companies, and coal enterprises as well as the equilibrium of a game between the safety management department and the employees of the coal enterprise in the face of high costs of implementing safety investment guarantee system in coal enterprises. We demonstrate the incentive compatibility and individual rationality conditions for the game among the government, insurance companies, and coal enterprises. These results offer a theoretical foundation for implementing the safety investment guarantee system in coal enterprises.作者单位:山东工商学院会计学

    [[abstract]]背景:過早入院到陌生醫療場景待產易使孕婦產生焦慮、不確定及失控感,教育孕婦等待適當入院時機,能減少往返產房與家中的辛苦,降低非必要醫療措施。目的:探討入院待產時機教育課程於孕婦焦慮、不確定感、生產控制感及待產結果之成效。方法:採類實驗設計,共收151位低危險群之單胞胎初孕婦,實驗組76位於妊娠35週以上的產檢日接受入院待產時機教育課程,課程次數為一次,共計一小時,課程內容分為三單元:「正常產兆與待產時機」、「產兆來臨之居家備忘錄」、「危險徵兆的認識」;控制組75位未接受。於介入方案前及產後3天內填寫結構式問卷:基本人口產科學資料、焦慮感與不確定感視覺類比量表、生產控制感量表以及待產結果資料。結果:入院待產時機教育課程能降低孕婦焦慮及不確定感(p < .001)、提高生產控制感(p = .001),掌握較正確入院時機(p = .001)、減少被拒絕入院返往家中的次數(p = .007)及諮詢次數(p < .001),提高子宮頸擴張達3公分後入院的比率(p < .001)以及降低催生機會(p = .002)。結論/實務應用:藉由入院待產時機教育課程,鼓勵孕婦無危險徵兆時,延長第一產程潛伏期居家時間,以降低焦慮、不確定感,提高生產控制感及較佳待產結

    化学物质的大量投入以及元素不能循环导致农田生态系统退化,耕地质量和产量均呈下降趋势,食物链受到污染.本研究从低产田开始,通过秸秆养牛、腐熟牛粪还田恢复地力;以物理+生物方法控制虫害;以人工+机械管理杂草,停用农药、化肥和除草剂,同时不用地膜、人工合成激素、转基因种子生产优质安全食品,并在线上与线下销售.10年的长期实验结果表明,所在村庄农田生态环境改善,减少农药用量58.3%;物理+生物控虫效果明显,每盏灯年捕获量从2009年的33 kg下降到2014年的2.1 kg,下降93.8%;年消耗秸秆1000 t,秸秆利用率从1.1%提高到62.5%.有机肥还田提高了土壤生物多样性,有机果园蚯蚓数量317条m~(-2),而普通果园只有16条m~(-2);大量有机肥还田(75 t hm~(-2)),土壤有机质从实验初期的0.7%提高到2.4%.粮食产量从最初的11.43 t hm~(-2)提高到目前的17.43 t hm~(-2),其中冬小麦(Triticum aestivum)、夏玉米(Zea mays)、大豆(Glycine max(Linn.)Merr.)和花生(Arachis hypogaea Linn.)产量分别超出山东省平均水平42.6%,60.9%,32.2%和38.1%.由于质量好,产品已销售往除西藏以外的30个省、市、自治区,经济效益明显,平均每公顷效益是普通农田的3~5倍,带动所在村庄67户农民从事高效生态农业.本研究可为国家制定生态农业发展规划、精准扶贫、农村环境保护等提供科学依据

    JUNO Sensitivity on Proton Decay pνˉK+p\to \bar\nu K^+ Searches

    The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this paper, the potential on searching for proton decay in pνˉK+p\to \bar\nu K^+ mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via pνˉK+p\to \bar\nu K^+ is 36.9% with a background level of 0.2 events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is 9.6×10339.6 \times 10^{33} years, competitive with the current best limits on the proton lifetime in this channel

    The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this study, the potential of searching for proton decay in the pνˉK+ p\to \bar{\nu} K^+ mode with JUNO is investigated. The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits suppression of the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via pνˉK+ p\to \bar{\nu} K^+ is 36.9% ± 4.9% with a background level of 0.2±0.05(syst)±0.2\pm 0.05({\rm syst})\pm 0.2(stat) 0.2({\rm stat}) events after 10 years of data collection. The estimated sensitivity based on 200 kton-years of exposure is 9.6×1033 9.6 \times 10^{33} years, which is competitive with the current best limits on the proton lifetime in this channel and complements the use of different detection technologies
