Martingale generalizations and preservation of martingale properties

This article investigates circumstances under which seven important martingale properties are preserved by the following six martingale generalizations: quasimartingales, amarts, martingales in the limit, games fairer with time, progressive martingales, and eventual martingales.

本文首先证明了区间空间上的几个参数型非空交定理,并由此得到拓扑Riesz空间中的几个新型极大极小定理,本文的结果包含[1、5、6]中主要结果为特例。     

Mixture of the Riesz Distribution with Respect to a Multivariate Poisson

The aim of this article is to study a statistical model obtained by the mixture of the Riesz probability distribution on symmetric matrices with respect to a multivariate Poisson distribution. We show that this distribution is related to the modified Bessel function of the first kind. We then determine the domain of the means and the variance function of the generated natural exponential family.     

“NP＋的＋VP”结构语义、语用功能浅析

通过回顾语言学界对“NP＋的＋VP”结构的认识和争议,详细分析了“NP＋的＋VP”的结构类型,并依据配价理论和心理空间理论考察了此结构的语义、语用功能,认为能够进入此结构的VP一般包含较多与动作有关的信息,二价三价动词数量占多数,“NP＋的＋VP”形成是语用上NP与VP相互选择的结果。

Wilks’ factorization of the matrix-variate Dirichlet–Riesz distributions

The Riesz distributions on positive definite symmetric matrices are used to introduce a class of Dirichlet–Riesz distributions. In addition, several distributional properties are stated. Essentially, we show the relationship between the Dirichlet–Riesz distributions of the first kind and the second kind, respectively. We derive Wilks’ factorization of the matrix-variate Dirichlet–Riesz. Further, several results on the product of Riesz and beta–Riesz matrices with a set of Dirichlet–Riesz matrices of the first kind have been derived.     

隐喻的认知机制:概念整合及影响隐喻构成的因素

本文首先概述了概念整合理论的基本内容和观点,并以实例分析了隐喻的认知机制是概念整合的"四空间"交互作用的语义认知模型和以心理空间为基础的相互关系、相互作用的认知过程;指出概念整合是一种普遍的认知活动,对隐喻具有强大的解释力。最后探讨了在概念整合框架下,影响隐喻阐释的因素。     

Risks and Responsibilities: Creating Dialogical Spaces in Northern Ireland

The idea that open dialogue is the key to transformative politics sounds straightforward. However, in a polity such as Northern Ireland where deep discord has intricate roots, an openness to difference is complex. I argue that dialogical spaces are created when people are prepared to engage in a risk-taking that conjoins self-disclosure with the vulnerability of being truly open to others; and are willing to bear the responsibility of mutually speaking with and listening to the plural other. First, I explain the relationship between identity, difference and political participation of women in Northern Ireland, examining alliance politics and solidarity. I offer suggestions for how difference, multiplicity and justice can be accommodated. Second, I extend beyond the specific context of Northern Ireland to evaluate the ability of feminist theories of deliberative democracy to facilitate dialogue across difference. I examine the importance of normative notions of deliberation, communication, narrative and competing needs. Third, I extrapolate from these theories the idea that the dynamic between listening and speaking creates a space to include diversity and commonality.

Assessing research impact potential: using the transdisciplinary Outcome Spaces Framework with New Zealand’s National Science Challenges

ABSTRACT

Calls for science to have impact as well as excellence have been loud and clear from research funders, policymakers and research institutions for some time. Transdisciplinary research (TDR) is expected to deliver impact by connecting scientists with stakeholders and end users to co-produce knowledge to respond to complex issues. While New Zealand’s science system is geared to deliver excellence, its capability to also deliver impact beyond academic institutions is less clear. This paper has two interconnected aims. Firstly, it presents findings from testing innovations to the TDR Outcome Spaces Framework (OSF+) with four National Science Challenges (NSCs). We conclude that OSF+ is a useful tool for planning for multiple outcomes and assessing the potential for impact. Secondly, it presents findings of how using OSF+ to assess research impact potential revealed a range of implicit theories of change (i.e. catalyst, deficit, engagement and collaboration) across the NSCs. The findings raise important questions about the prospects for New Zealand’s science system to deliver the envisaged and needed levels of research impact when current institutional settings, expectations, recognition systems, career paths and measures of success are not yet able to adequately accommodate TDR to deliver the research impact.
