高危时代全球治理与多元主体参与模式的研究

人类社会正步入一个危机四伏的“高危时代”，这对传统的以家庭、国家为中心的危机治理提出了挑战。为了全面有效应对各种全球性、区域性的新型危机，提出了由国际组织、民族国家、非政府组织、企业、民众以及媒体等多元主体参与的全球治理模式。     

Understanding Synaesthesia-A Cognitive Perspective

Synaesthetic Metaphor is a universal phenomenon in language.I attempt to study it from a new cognitive perspective---Innatism and Embodied Philosophy,and try to achieve the dialectical unity of two philosophy views.     

Applying multiple regression analysis to the forecasting of grocery store sales: an application and critical appraisal

Multiple regression analysis is applied to an analysis of the trading performance of a chain of grocery stores in the north-east of England. The performance of stores outside the conurbations is shown to be related to characteristics of the OPCS ‘urban-areas’ in which the stores are located, and a way is presented of modelling the effect of competition from within and outside these centres.

A high degree of statistical explanation is achieved, and the methodology used is defended against criticisms that can be levelled at many of other multiple regression analyses of store performance. Caution is nevertheless advised against the application of the model to forecasting the performance of new stores, although a range of applications are suggested whereby the implications of changes in the trading circumstances of existing stores might be examined.

Optimal management of annual ryegrass (Lolium rigidum Gaud.) in phase rotations in the Western Australian Wheatbelt*

Lucerne (Medicago sativa L.) helps to prevent soil salinisation in the Western Australian Wheatbelt by reducing recharge to saline water tables. There is broad consensus, though, that it is not sufficiently profitable to motivate producers to plant it at the intensity at which considerable off‐site benefits would be conferred. This paper employs a multiple‐phase optimal control model to explore the value of this perennial pasture for the management of herbicide‐resistant annual ryegrass (Lolium rigidum Gaud.) in a crop–pasture rotation, given the difficulty of observing this value in practice. The availability of selective herbicides for efficient weed control is found to determine whether or not it is profitable to adopt lucerne pasture under optimal management. Herbicide resistance requires producers to employ costly, non‐selective treatments for in‐crop weed control. Thus, it motivates the adoption of perennial pasture in which cost‐effective forms of control can be implemented. Moreover, this result is robust to feasible changes in the current economic environment.     

On some noncentral distribution problems for the mixture of two normal populations

Summary The null density of the multiple correlation coefficient when sampling from a mixture of two normal populations has been derived by Srivastava (1983). However, he does not express this density in a rather standard form. The present paper obtains the nonnull densities of the multiple correlation coefficient and the partial correlation coefficient in a rather standard form when sampling from a mixture of two normal populations.     

基于模糊均值聚类和感知机的网络银行客户挖掘

通过结合运用模糊均值聚类和感知机进行网络银行目标营销,首先利用模糊c均值方法(FCM)找出频繁使用网络银行服务的客户,再进一步用这些客户样本对一个多层感知机(MLP)进行训练,最后利用训练好的感知机对银行的非网络银行注册客户进行分类,找出潜在的网上银行服务频繁使用者,银行即可对这些客户进行重点推广网络银行服务。

农村居民点综合破碎度评价及影响因素探测*——以山东日照市为例

[目的]尝试借鉴景观格局的研究思路,对农村居民点破碎化程度进行评价及其影响因素分析,为当前"新农村建设"中合理进行土地整治提供辅助依据。[方法]充分考虑农村居民点的规模、形状和分布特征,构建了乡镇尺度上的农村居民点综合破碎度评价模型,并利用多元回归模型对其影响因素进行了分析,提出了居民点整理模式的针对性建议。[结果]以沿海平原地区——山东日照为例的研究结果表明:(1)农村居民点破碎度综合指数(FCI)能够较好地反映沿海平原地区农村居民点的空间分异特征;沿海地区FCI大于内陆地区,形成了"阶梯状"的空间分布格局。(2)多元回归模型可以较为准确地探测出破碎度影响因素;研究区FCI的显著影响因素包括距海岸线的距离、距县城的距离、坡度、道路密度等。[结论]通过分析不同等级破碎度的分布特征及其影响因素,可以为各地政府因地制宜开展土地整治、城乡协调发展和新农村建设的土地利用决策提供参考依据。     

论脱贫攻坚对推动乡村振兴的多重作用

脱贫攻坚和乡村振兴是以习近平同志为核心的党中央关于农村建设发展提出的两项重大战略部署。以马克思主义的视角观之,脱贫攻坚对于乡村振兴战略的实施具有重要的基础作用,且这种基础作用具有多重性。脱贫攻坚通过消除贫困、弥补短板、重塑组织、改善系统等,为乡村振兴战略的实施创造前提条件、搭建基础平台、提供组织保障、营造有利环境,从而使乡村振兴战略在农村贫困地区的实施不仅可能,而且可行。为确保乡村振兴战略在农村贫困地区的顺利实施,必须不断夯实脱贫攻坚各项工作,坚决、彻底、全面地打赢脱贫攻坚战,使脱贫攻坚对乡村振兴的多重基础性作用得到充分彰显,从而实现脱贫攻坚与乡村振兴的有机衔接。
