新型城镇化水平综合评价研究

新型城镇化是城市发展的目标,评价新型城镇化水平有助于提高市民生活质量和城市竞争力,因而对新型城镇化水平进行综合评价至关重要。将文化潜力要素加入改进的“星系”模型来构建新型城镇化水平评价体系,以成熟的专家意见法、相关分析法制定基于两步筛选法的新型城镇化水平评价指标体系技术路线,并采用融合了360度专家反馈法的模糊综合评价法对沈阳市进行新型城镇化水平综合评价。通过实例验证,沈阳市发展水平的综合评价真实有效,旨对新型城镇化发展提供参考。     

认知反应理论视角下领导幽默触发下属积极情绪的跨层研究

从认知反应理论的视角,基于43名团队主管和317名下属的配对数据,揭示领导幽默触发下属积极情绪的内在机制。研究结果表明:领导幽默能有效触发下属的积极情绪,并且只有通过被下属感知的领导幽默才能对下属积极情绪产生间接作用;下属的幽默喜好能增强其感知的领导幽默对积极情绪的预测效度;下属的幽默元信息敏感度并不能强化领导幽默对其感知的领导幽默的驱动有效性。     

区间直觉模糊数环境下基于犹豫度和相关系数的多属性群决策模型研究

多属性群决策问题是当今复杂决策环境下的研究热点,而区间直觉模糊数可以从隶属度、非隶属度和犹豫度三方面描述不确定信息,具有很强的表现能力,因此学界基于区间直觉模糊数对多属性群决策问题进行了大量研究。但是现有研究一方面在处理共识达成问题时所广泛采用的"多数原则"策略会导致某些关键信息或知识被视为冲突意见而被修改或忽视;另一方面基于距离的区间直觉模糊数相似性测算方法忽略了犹豫度的影响,会造成评价信息损失。针对上述不足,提出区间直觉模糊数环境下基于犹豫度和相关系数的多属性群决策模型。首先,通过个体犹豫度和群体犹豫度的提出,保证了决策群体内部信息和知识的有效交流,使关键性决策信息或知识不会通过强制修改或删除的方式失效;其次,采用区间直觉模糊数相关系数测量相似度,避免基于距离测算而可能出现的错误结果;继而,将决策主体权重设置为区间直觉模糊数形式,通过计算不同决策者之间的相对优势值和劣势值进行主观赋值,保证了决策者权重的客观性和真实性;此外,结合TOPSIS和线性规划方法求解得到最优属性权重,保证了属性赋值的精确性,最后,通过具体的应用实例以及与当前学界主要研究成果的比较分析,进一步论证了所提模型的优势和创新性。     

玉米雄穗性状的配合力及相关研究

以南21－3等7个玉米自交系为亲本,按照双列设计组配一套不包括反交的组合。对雄穗主轴长、雄穗分枝数、雄穗总分枝长进行配合力分析及相关研究。结果表明,3个雄穗性状的GCA、SCA效应及变异程度均存在显著差异;3个雄稳性状的GCA、SCA与其性状表现型值（X）存在显著或极显著正相关。除主轴长与分枝数的GCA外,3个雄穗性状的GCA和SCA之间具有极显著的相关关系。     

苎麻纯落麻转杯纺成纱断头的研究

本文用灰色关联分析法,分析了转杯纺加工苎麻纯落麻纺纱断头与主要影响因素的关联程度,指出各影响因素的优势序列,即影响最显著的是转杯凝聚槽内积灰量,其次分别为转杯速度、喂入定量、假捻盘的假捻效应和捻系数。本文还对影响凝聚槽内积灰量的因素进行了分析。     

Estimates of the Number of Liver Carcinogens in Bioassays Conducted by the National Toxicology Program

Estimates were made of the numbers of liver carcinogens in 390 long-term bioassays conducted by the National Toxicology Program (NTP). These estimates were obtained from examination of the global pattern of p-values obtained from statistical tests applied to individual bioassays. Representative estimates of the number of liver carcinogens (90% confidence interval in parentheses) obtained in our analysis compared to NTP's determination are as follows: female rats—49 (23, 76), NTP = 30; male rats—88 (59, 116), NTP = 35; female mice—131 (105, 157), NTP = 81; male mice—100 (73, 126), NTP = 61; overall—166 (135, 197), NTP = 108. The estimator from which these estimates were obtained is biased low by an unknown amount. Consequently, this study provides persuasive evidence of the existence of more rodent liver carcinogens than were identified by the NTP.     

为何民法要分物权和债权？

大陆法系国家的民法及其理论体系多建立在区分物权与债权的基础上。然而,为何立法和理论上会发展出物债二分？对于这个根本性的问题,学界至今未能提出完整的解释。目前的相关理论有道德哲学说、交易安全说、请求权说,都有各自的缺陷。从法外视角提出的“时间落差”说能有效解释此问题。在生活中,交易并非瞬间完成,往往存在时间差,这是民法区分物权和债权的根本原因。

Spatial effects in dynamic conditional correlations

The recent literature on time series has developed a lot of models for the analysis of the dynamic conditional correlation, involving the same variable observed in different locations; very often, in this framework, the consideration of the spatial interactions is omitted. We propose to extend a time-varying conditional correlation model (following an autoregressive moving average dynamics) to include the spatial effects, with a specification depending on the local spatial interactions. The spatial part is based on a fixed symmetric weight matrix, called Gaussian kernel matrix, but its effect will vary along the time depending on the degree of time correlation in a certain period. We show the theoretical aspects, with the support of simulation experiments, and apply this methodology to two space–time data sets, in a demographic and a financial framework, respectively.     

Modelling Aggregation on the Large Scale and Regularity on the Small Scale in Spatial Point Pattern Datasets

We consider a dependent thinning of a regular point process with the aim of obtaining aggregation on the large scale and regularity on the small scale in the resulting target point process of retained points. Various parametric models for the underlying processes are suggested and the properties of the target point process are studied. Simulation and inference procedures are discussed when a realization of the target point process is observed, depending on whether the thinned points are observed or not. The paper extends previous work by Dietrich Stoyan on interrupted point processes.
