Both the Europea. Union （EU） a.d China.a.e cultura.ly, economica.ly, clima.ologica.ly a.d environmenta.ly diverse polities. The EU is a.multi-sta.e grouping of economica.ly developed democra.ic countries, while China.is a.unita.y sovereign sta.e a.d a.developing economy with a.strong government burea.cra.y. Our hypothesis is tha. given their diverse politica. systems, the EU a.d China.would develop different kinds of systems for the governa.ce of a.a.ta.ion to clima.e cha.ge. We test this hypothesis through a.compa.a.ive a.a.ysis of policy documents from the two study a.ea., in which we exa.ine fra.ework policies, progra.ma.ic a.tions a.d specific a.tions tha. ha.e been a.opted to da.e in order to a.dress clima.e cha.ge, with a.specific focus on the wa.er sector. We find tha. clima.e cha.ge a.a.ta.ion bega. to be a.dressed through forma. policy on a.simila. timeline in the two regions. The EU a.d China.a.e a.so simila. in tha. they use fra.ework la.s a.d existing sectora. policy, such a. for the wa.er sector. We find tha. the EU ha. prima.ily relied on integra.ion of clima.e cha.ge a.a.ta.ion concerns through lega. instruments which set a.fra.ework for implementa.ion of a.a.ta.ion policy. In China. specific a.tions to be incorpora.ed in socio-economic development pla.s under the existing legisla.ion on a.a.ta.ion ha.e been the ma.n mode for integra.ing a.a.ta.ion into sectora. a.tions, though the future trend ma. be to develop more regula.ions.

以阉牦牛提前出栏项目活动为例,按照2006年IPCC国家温室气体清单优良做法指南的计量方法,在同等牧草利用量的前提下,分别对4岁和7岁阉牦牛一生CH4排放总量和单位体重CH4排放量(即排放强度)进行了初步比较分析.发现在同等牧草利用量的基础上,由于饲养一头7岁阉牦牛一生所消耗的牧草量相当于可饲养2.1头4岁的阉牦牛所消耗的牧草量,所以从CH4排放总量而言,前者一生排放CH4总量比后者少86.3 kg.然而,由于后者总体重比前者重192 kg,所以,后者的单位体重CH4排放强度(以CH4/体重计)只有0.973 kg·kg-1,而前者为1.374 kg·kg-1.根据排放强度的概念,在同等牧草消耗量的基础上,如果将一头7岁阉牦牛替代成饲养2.1头4岁的阉牦牛,可以多生产192 kg的活体重,在同样生产192 kg活重的基础上,利用替代法估算后者饲养方式比前者饲养方式可以实现77 kg CH4减排量,即相当于总减排1.6 t CO2当量.因此,基于排放强度减排而不是总量减排的概念,提前出栏有较大的CH4减排潜力.

Clinica. judgement is a. importa.t component of sa.e a.d effective nursing ca.e. Clinica. judgement rema.ns a.cha.lenging cognitive process to a.ticula.e a.d a.sess. a. integra.ive review of the litera.ure conducted in 2016 identified 13 cha.a.teristics of clinica. judgement. This pa.er reports the results of a.2-pha.e survey to obta.n consensus whether these cha.a.teristics identified a.cura.ely represented nurses’ perception of clinica. judgement. The 2-pha.e survey wa. a.ministered via.a. online survey softwa.e tool. The survey in pha.e 1 sought Yes/No a.swers for nurse a.a.emics with recruitment via.a.hyperlink in a. ema.l to individua.s identified from University websites, Google a.d published a.ticles. In pha.e 2, the survey wa. modified to a.Likert sca.e a.d recruitment occurred via.online networks a.d wa. open to a.l nurses. The results identified tha. the cha.a.teristics a.cura.ely represented the nurse’s perception of clinica. judgement. By a.ticula.ing the cha.a.teristics, it a.lows clinica. judgement to be ea.ily described a.d ca. therefore be a.plied to both nursing resea.ch a.d educa.ion.

Food a.lergies represent a.clea. threa. to the genera. hea.th a.d wellbeing of those a.fected which pla.e increa.ing pressure on food producers a.d regula.ory a.thorities. Current a.a.ytica. techniques typica.ly find difficulties distinguishing between closely rela.ed Prunus species which include a.mond (Prunus dulcis), a. EU listed a.lergenic species. This study describes a.proof of principle rea.-time PCR a.proa.h utilising DNa.melt a.a.yses tha. ta.gets the interna. tra.scribed spa.er (ITS) sequence to differentia.e between a.pa.el of Prunus test species. The method wa. successfully a.plied to the cha.a.terisa.ion of a.commercia. pa.rika.sa.ple suspected of ha.ing being a.ultera.ed with a.mond, referred to the UK Government Chemist in 2015 in its a.visory ca.a.ity. Subject to further va.ida.ion work, the method a.pea.s to specifica.ly a.plify Prunus species a.d is ca.a.le of discrimina.ion ba.ed on the resulta.t melt profiles. The developed method provides a.a.ysts with a.simple a.d broa. molecula. tool to identify common Prunus species for food a.thenticity a.d a.lergen testing purposes. Initia. development work demonstra.es a.promising a.proa.h with the potentia. to improve discrimina.ion between Prunus species not ea.ily resolved by routine a.a.ytica. methods.

为研究我国主要农作物(粮食、水果、油料、糖料和棉花作物)产量波动特征及相关影响因素,以我国1981～2010年主要农作物产量和种植面积资料为基础,同时利用4种方法对农作物单产进行趋势拟合与分解。结果表明:(1)近30年来我国农作物总产和单产都逐步提高,特别是水果产量的增长最快,其中柑橘单产年均增长率达7.09%;各类作物趋势产量也呈上升趋势;但气象产量波动剧烈,年际间缺乏连续性,其中水果气象产量波动幅度最大(柑橘为17.76%、苹果为15.83%)。(2)作物总产的年际波动中,种植面积和单产因素的贡献率因作物类型不同而有所差异,其中粮食作物和水果总产波动的主要原因是单产波动,糖料作物和棉花产量波动主要因种植面积波动导致,油料作物总产的波动中单产和种植面积贡献相当。(3)各类作物单产年际波动均取决于气象因素,农业政策和科技进步等社会因素对单产年际波动的贡献较低。(4)作物趋势产量的4种拟合方法,其结果无显著差异。各影响因素对我国农作物产量波动的贡献率因作物类型不同而有所差异;重视作物单产提高、关注气候变化对农作物生产的影响是目前我国农业安全生产的重要任务。
