Twelve years have passed since the advent of g.ammatical evolution (g.) in 1998, but such issues as vast search space, g.notypic readability, and the inherent relationship among.g.ammatical concepts, production rules and derivations have remained untouched in almost all existing.g. researches. Model-based approach is an attractive method to achieve different objectives of software eng.neering. In this paper, we make the first attempt to model syntactically usable information of g. using.an automaton, coming.up with a novel solution called model-based g.ammatical evolution (Mg.) to these problems. In Mg., the search space is reduced dramatically throug. the use of concepts from building.blocks, but the functionality and expressiveness are still the same as that of classical g.. Besides, complex evolutionary process can visually be analyzed in the context of transition diag.ams.

Cull sow physical conditions were associated with on-farm production records. Sows (923) within one integ.ated U.S. production system were evaluated at two harvest facilities. Physical conditions evaluated at harvest were analyzed by parity, culling.code and production measures. Farm culling.codes were categ.rized into poor body condition (BC), old ag. (g., lameness (L), other (O), poor litter performance (P) and reproductive failure (R). Production measures included lifetime pig. born alive (LPBA), pig. born alive in the last litter (PBALL), pig. per sow per year (PSY) and weaning.to culling.interval. The L culling.code had a g.eater (P g.codes (30.9% vs. 18.7%). Sows without front cracked hooves tended (P = 0.07) to have g.eater PSY (0.80) when compared to sows having.front cracked hooves. Females without rear dig.tal overg.owth had more (P g.tal overg.owth. Sows without shoulder lesions had g.eater (P g.ession coefficient estimates for percent lung.lesion involvement were positive and tended (P g.codes (1.83 and 2.04 cm vs. 2.47 to 2.85 cm, respectively). Multiple cull sow physical conditions evaluated at harvest had associations with on-farm reproductive measures.

一个名为"STOCHEM"的三维拉氏化学传输模型被用于描述2000年气候条件下国际海运活动产生的SO_2、NO_x、VOCs和CO排放造成的欧洲大西洋沿岸区域性酸性沉降和臭氧空气质量影响的状况。该模型得出的从西南海域到不列颠群岛和布列塔尼水域国际海运活动产生的硫沉降总量高达200mg.m^2·a。夏季国际海运活动对表层臭氧浓度的影响在爱尔兰、布列塔尼和葡萄牙高达约6ppb。在欧洲,海运活动产生的排放物是一种对酸性沉降和臭氧空气质量造成影响的外部因素,并且如果要在将来达到严格的沉降及空气质量目标,就需要采取一系列控制措施。

一、问题过去十多年里,管理会计研究方法最引人注目的变化之一就是重视和强调对管理会计实务的论证性实证研究,包括组织问卷调查、实地查访及进行深入的案例研究。此变化起初归因于Kaplan和johnson教授于80年代对一些公司进行调查后,对管理会计研究提出的尖锐批评。他们认为,管理会计的学术研究及教科书均热衷于建立和发展高深莫测的模式,而与实务工作者面对的问题不相关,因此。
