融贯中西与古今文化诗学的意象体系——鲁迅诗歌意象的类型分析

意象是诗歌的生命。鲁迅诗歌使用了大量的审美意象,融贯中西与古今文化诗学,形成了自己独立的体系。鲁迅诗歌意象为六种类型,以三组对立的形态出现,即:历史性意象/现实性意象;东方意象/西方意象;社会性意象/人化自然的意象。这些意象的使用,昭示了鲁迅忧国忧民的伟大人格,并形成鲁迅自己独特的诗风。同时,他的诗歌与我国传统诗歌相比较,具有鲜明的现代性,与后起的新诗相比,又具有深厚的传统文化诗学的底蕴。

论现代企业经营思想

企业行为受其经营思想的支配,企业的经营思想取决于企业所处的客观环境。在市场经济与现代企业制度的约束下,企业普遍应树立的经营思想有:守法观念、效益观念、用户观念、创新观念、竞争观念和战略观念。各种观念应当互为配合,形成一个有机的整体。     

液相色谱串联质谱检测鳗鱼中四种氟喹诺酮残留

建立了液相色谱/串联质谱法测定鳗鱼中恩诺沙星,环丙沙星,诺氟沙星,氧氟沙星的方法。对分离和检测这四种兽药残留的液相色谱条件、质谱条件、样品前处理方法等作了详细的研究。用乙腈萃取样品中的残留物,在氮气保护下将萃取液浓缩干,加流动相1.0mL溶解残渣,正己烷液液萃取,弃上层液,下层溶液用作液相色谱分析荧光检测或质谱检测。在鳗鱼样品中添加四种残留物,添加浓度分别为0.01,0.050和0.100mg/kg,平均回收率(n=6)在70￣84.3%之间,相对标准偏差为3.0%～6.3%。     

婚龄性别比失衡对社会运行和发展的影响——来自吉林省延边朝鲜族自治州农村地区的调查分析

婚龄性别比失衡问题到底有什么样的社会影响?这些社会影响的性质、影响范围以及具体表现又是怎样?为了回答这些问题,我们对延边地区进行了实地调查和深度访谈,发现该地区的婚龄男女性别比失衡相当明显。在这些地区,由于婚龄女性人口的大量向城市(国外)流动,当地的很多成年男性到了婚龄,都面临着无妻可娶的窘境。由此,对社会造成了一些负面的影响,社会运行和发展出现了一定程度上的离轨。     

斜腿刚构桥几何布局的优化设计

采用数学规划的方法从静力和动力两方面对斜腿刚构桥的几何布局进行优化设计。静力优化设计的优化目标是截面截面应力平方均值最小，动力优化设计的优化目标是结构自振周期平方和最小。采用了直接搜索法寻优。通过算例可知，这两种优化设计方法均可行，且均为刚性设计。     

The current state of the labor queue: National and regional Evidence

We employ vector autoregressive techniques to determine the current state of the labor queue. Unemployment rate differentials have narrowed in recent years, potentially due to a change in the queue ordering, though a tight labor market and a stable queue would yield similar results. We find no evidence that the queue ordering has changed, which brings into question the resiliency of gains made by minority groups. We employ the same techniques to reveal the state of the queue across geographic regions and find that substantial differences exist across regions, implying variation in the relative labor force status of demographic groups.     

体验、解析、会通——张岱年哲学方法论的综合创新

体验、解析、会通的有机统一,是张岱年《天人五论》所建构的哲学方法论。这种方法论排斥直觉法,因而不同于现代新儒家和清华学派的哲学家;同时,它把辩证法看成一般的学术方法而非独立的哲学方法,这又使其不同于当时的新唯物论者。这种方法论是在综合中西哲学方法以及近现代各派哲学方法基础上的一个综合创造。

抗战时期中共执政陕甘宁边区的成功实践,把陕甘宁边区建设成了抗日民主政治的模范区、新经济生活的模范区、建设先进文化的楷模,为中共全国范围内的执政做了有益的尝试,积累了丰富的经验。学术界对中共执政陕甘宁边区的研究主要涉及民主建政、发展经济、建设新文化、当代意义等方面。     

Bayesian analysis of a marked point process: Application in seismic hazard assessment

Point processes are the stochastic models most suitable for describing physical phenomena that appear at irregularly spaced times, such as the earthquakes. These processes are uniquely characterized by their conditional intensity, that is, by the probability that an event will occur in the infinitesimal interval (t, t+Δt), given the history of the process up tot. The seismic phenomenon displays different behaviours on different time and size scales; in particular, the occurrence of destructive shocks over some centuries in a seismogenic region may be explained by the elastic rebound theory. This theory has inspired the so-called stress release models: their conditional intensity translates the idea that an earthquake produces a sudden decrease in the amount of strain accumulated gradually over time along a fault, and the subsequent event occurs when the stress exceeds the strength of the medium. This study has a double objective: the formulation of these models in the Bayesian framework, and the assignment to each event of a mark, that is its magnitude, modelled through a distribution that depends at timet on the stress level accumulated up to that instant. The resulting parameter space is constrained and dependent on the data, complicating Bayesian computation and analysis. We have resorted to Monte Carlo methods to solve these problems.
