Model diagnostics for smoothing spline ANOVA models

The author proposes some simple diagnostics for assessing the necessity of selected terms in smoothing spline ANOVA models. The elimination of practically insignificant terms generally enhances the interpretability of the estimates and sometimes may also have inferential implications. The diagnostics are derived from Kullback‐Leibler geometry and are illustrated in the settings of regression, probability density estimation, and hazard rate estimation.

Risk,trust and knowledge networks in farmers’ learning

This study reports on New Zealand dairy farmers’ access to and use of information as mediated through conditions of risk and trust within the context of their interpersonal social networks. We located participants’ reports of their information use within their perceived environments of trust and risk, following Giddens's [1990. The consequences of modernity. Polity Press, Stanford, CA] typology of trust and risk in pre-modernity and modernity. The research participants were constant users of interpersonal and print information from numerous sources, and monitored their incoming data in the light of strategic needs, reflecting their roles as both farming practitioners and business owners. Socio-spatial knowledge networks (SSKNs) combine individuals’ explanatory cognitive models of information acquisition and use with a micro-geographical analysis of their interpersonal networks. The participants showed characteristics of pre-modern, modern and even post-modern society in respect of their use of complex interactional forms, as well as a blending of individualistic and communitarian practices and concerns in their professional and personal lives.

两种财产权的均衡--一种宪政隐喻的研究

在某种意义上,“公共财产神圣不可侵犯”的宪法宣言彰显了社会主义对资本主义的批判;“私有财产权不可侵犯”的神圣入宪隐喻了宪政的理性。私有财产权与公有财产权的均衡宪制是一种“社会能量守恒定律”的宪政隐喻。这两种基本财产权的均衡态势既有静态的平衡,也有动态的衡平,并展现为“一明两暗”的对立形态和以人为目的的终极关怀。由于这种均衡态势在各国宪法中展现的侧重点不同,而成为各国形成不同的宪政观念的重要原因之一,这便是宪政的隐喻所在。在三种不同模式的宪法中检讨这一隐喻,为当下解构、建构和创新中国的宪政理念与制度具有重大意义。     

改善全息圆锥准直线及提高准直精度的一种方法

用一张计算全息图可产生锥面波,锥面波衍射图样的中心在空间是连续的,可作为直线基准。本文提出了提高锥面波直线准直精度的一种方法即空间滤波法。实验结果与理论分析一致。     

超验主义主体思想与儒家角色伦理学

爱默生、梭罗和惠特曼的肯定性“自我”书写与霍桑、梅尔维尔、爱伦·坡等的否定性“自我”书写共同为美国独立民族意识和国族文学的构建奠定了基础。美国的个人主义更深入地植根于前者的超验主义主体思想中,但由于对“自我”内在神性和超验原则的强调,其主体思想陷入唯我和超验的困境,促使他们不得不进行反思与修正。当代美国哲学家、汉学家安乐哲吸收中西传统的有关思想,提出以儒家角色伦理学作为走出西方个人主义困境的有效途径。爱默生、梭罗和惠特曼的“自我”书写与儒家角色伦理学的人学思想有趋同倾向,前者呈现从抽象道德主体到具象道德主体、从自我内在性到自然外在性及群体外在性的转变趋势,这一转向与儒家角色伦理学对具象外在性人际关系的关注有共通之处,由此可见儒家思想的普遍意义。

A case study of the labour market status of recent mainland Chinese immigrants,metropolitan Toronto

"This article focuses on an analysis of the labour market status of recent MCIs [mainland Chinese immigrants to Canada], taking into account such factors as gender, educational attainment, language proficiency and period of arrival (or length of residence in Canada), and uses Metropolitan Toronto as a case study. The effect of each factor on MCIs' labour market status will be analysed separately, followed by two logit models examining the simultaneous effects of the factors and their relative importance."
