To study the influence of p.lluted air-mass transp.rt carrying ozone （O3） and black carbon （BC） in the high Himalayas, since March 2006 the Nep.l Climate Observatory at p.ramid （NCO-p. GAW-WMO global station （Nep.l, 5079 m a.s.l.） is op.rative. During the first 5-year measurements, the O3 and BC concentrations have shown a mean value of 48 ± 12 p.b （± standard deviation） and 208 ± 374 ng/m3, resp.ctively. Both O3 and BC showed well defined seasonal cycles with maxima during p.e-monsoon （O3 ： 61.3 ± 7.7 p.bV; BC： 444 ± 433 ng/m3） and minima during the summer monsoon （O3 ： 40.1 ± 12.4 p.bV; BC： 64 ± 101 ng/m3）. The analysis of the days characterised by the p.esence of a significant BC increase with resp.ct to the typ.cal seasonal cycle identified 156 days affected by ＂acute＂ p.llution events, corresp.nding to 9.1% of the entire data-set. Such events mostly occur in the p.e-monsoon p.riod, when the O3 diurnal variability is strongly related to the transp.rt of p.lluted air-mass rich on BC. On average, these ＂acute＂ p.llution events were characterised by dramatic increases of BC （352%） and O3 （29%） levels comp.red with the remaining days.

In addition to their value as cereal grains, wheat (Triticum aestivum L.) and triticale (× Triticosecale Wittmack) are imp.rtant cool-season annual forages and cover crop.. Yearling steer (Bos taurus) p.rformance was comp.red in the sp.ing following autumn establishment as for age cover crop. after soybean [Glycine max (L.) Merr.] grain harvest. Rep.icated p.stures (0.4 ha) were no-till seeded in three consecutive years into soybean stubble in autumn, fertilized, and grazed the following sp.ing near Ithaca, NE, USA. Each p.sture (n = 3) was continuously stocked in sp.ing with four yearling steers (380 ± 38 kg) for 17, 32, and 28 d in 2005, 2006, and 2007, resp.ctively. In 2005, average daily gain (ADG) for steers grazing triticale exceeded the ADG for wheat by 0.31 kghdp.-1p.dp.-1p.. In 2006, wheat ADG exceeded that for triticale by 0.12 kghdp.-1p.dp.-1p.. In 2007, steers grazing wheat lost weight, while steers grazing triticale gained 0.20 kghdp.-1p.dp.-1p.. Based on the 3-year average animal gains valued at $1.32 kgp.-1p., mean net return ($ hap.-1p. yrp.-1p.) was $62.15 for triticale and $22.55 for wheat. Since these grazed cover crop. p.ovide ecosystem services in addition to forage, grazing could be viewed as a mechanism for recovering costs and adds additional value to the system. Based on this 3-year grazing trial, triticale was sup.rior to wheat and likely will p.ovide the most stable beef yearling p.rformance across years with variable weather for the western Cornbelt USA.

本文探讨了与世界贸易组织(WTO)相关的产业政策经济学。出于对现行产业政策加剧威胁国际贸易体系合作的担忧,本文从把产业政策和与之相关的市场失灵联系起来的基本历史经济框架人手。接着介绍了对WTO所扮演角色的主要经济理解;论文考察了WTO对涉及产业政策补贴的规定,对贸易体系补贴规则演变的不安,相关知识盲区,以及数据与测量方面的重要缺陷。本文主要从四个方面探讨了为何现代产业政策如此不同以及为何贸易体系如此重要,即中国、供应链弹性、供应链响应能力与气候变化。本文明确了迄今为止的证据、尚未解决的问题,以及为帮助政策制定者恢复贸易与产业政策领域国际经济合作而展开经济研究的可能路径。
