基于AHP的新疆生产建设兵团城镇化水平评价

从社会发展经济建设、社会稳定和生态环境4个方面选取20个评价因子,建立新疆生产建设兵团城镇化水平评价指标体系,运用层次分析法,分别构造判断矩阵,对新疆兵团14个师的城镇化水平做出了评价;采用因子分析法,构建新疆兵团城镇化评价模型,对新疆兵团城镇化发展水平进行了评估。通过SAS软件,得到新疆兵团14个师城镇化发展水平的排名,从而验证了模型的科学性和实用性。     

住房抵押贷款风险控制实证研究——基于中国银行某分行的数据分析

王先谦的《荀子集解》一书，是晚清诸子学的一部重要著述，是研究和整理《荀子》一书的集大成之作。王氏的学术成就主要体现在两个方面：一是他吸纳了清代学者中研究和整理杨倞注《荀子》一书最有代表性的成果，并对各家之说作了一个梳理和辨析；二是他个人对《荀子》以及杨注的校勘、注释、考辨等方面超出了前人的成就。     

我国特大城市建成区土地集约利用研究

运用因子分析法对我国16个特大城市建成区的土地集约利用水平进行综合评价和排序.结果表明：我国特大城市建成区土地集约利用效率呈现总体水平偏低、地区差异明显及各大城市影响因素侧重点不同等3大特征.因此,需合理调整各大城市产业结构,以促进城市经济可持续发展;积极开展城市土地整理,以提高土地利用效率;加大城市生态环境保护力度,以优化土地利用生态效益.

Testing genetic determinism in rate of hoof growth in pigs using Bayes Factors

Excessive growth and consequent deformity of hooves is a frequent disorder in some purebred pig populations. A test to detect possible genetic determinism related with this phenomenon was performed using the Bayes Factor (BF). Data were available for females from three purebred selection lines: Landrace (561 records), Pietrain (183) and Large White (225). Animals were scored in four categories, according to the overall growth rate of their hooves. A Bayesian analysis was performed separately for each line using a threshold model with a probit approach, and Bayes Factors between models with and without additive genetic effects were computed. Results from the three lines showed that models exhibiting genetic variability were much more probable than those that did not include a genetic component, with BF values of 312, 35 and 40 (and posterior probabilities of 0.99, 0.97 and 0.98), respectively, for the Landrace, Pietrain and Large White lines. Monte Carlo estimates of posterior means of heritabilities were medium to high (0.25, 0.41 and 0.38, respectively), and the highest posterior density region for heritability at 99% did not include zero in any of the three lines. These results allow us to conclude that genetic determinism has an important influence upon the rate of hoof growth in the pig. A potential genetic response can be achieved in the populations analysed, but further studies are needed to determine the genetic architecture of hoof growth disorders in pigs.

Opelug-ontspanning op Boseiendomme

Insect-induced damage to leaves, and the growth phenology, of Olea europaea subsp. africana and Kiggelaria africana near Stellenbosch (33° 56'S, 18° 52'E) were monitored at weekly intervals between July 1980 and June 1981. The average incidence of damaged leaves was greater in K. africana than in O.e. africana (14 vs 10 %, respectively). In both species, leaf-damage appeared to be slightly more than twice as great in January-June than in July-December, and insect attacks on leaves apparently began to intensify after the plants had completed their main growth and production of new leaves in the austral spring. These findings are discussed in relation to the meagre published information on herbivory in the fynbos biome.

菏泽霾气候特征及影响因素分析

利用1981-2013年菏泽市地面气象观测资料,对菏泽市霾日数变化特征及其影响因素进行了分析.结果表明：近33年菏泽霾日数总体呈上升趋势,1980-1990年代霾日数较少,2000年之后明显上升.菏泽年平均霾日数为10.8天.菏泽秋冬季霾天气出现多,春夏季出现少.菏泽霾天气95％以上为轻微霾（大气能见度5～10 km）,相对湿度在70％～90％的占8成以上.霾日数变化对气温和风速的变化较为敏感.霾天气发生时,一般风速比较小（1～2 m/s）,并以N风最多.正变湿和负变压对霾的生成和维持更加有利.连续无降水日数越长,出现霾的概率就可能越大.
