论台湾原住民的书写策略:从文化符号学的角度观察

台湾原住民如何在以汉文化为中心的文化域中实现文化主体性的重建一直以来是学术界关注的焦点所在。本文试从文化符号学的角度出发,对原住民书写的书写策略、多重发声现象和写作疆界进行考察和讨论,从而指出语言、创作形式的互补和书写题材的越界对原住民自身文化保持丰富性和创造性具有重要意义,并将对文化和价值的多元发展提供了可能。     

上下游市场存在竞争的企业集团转移定价研究

基于不对称的竞争环境,研究了企业集团的中间产品的转移定价问题,研究结果表明,中间产品的转移定价策略取决于上游子公司和上游竞争公司之间的不对称程度:当不对称程度较大时,企业集团应采取Hirshleifer的边际成本转移定价策略;当不对称程度较小时,企业集团应采取部分非中心化结构的转移定价策略。     

Estimating Conditional Probabilities of Terrorist Attacks: Modeling Adversaries with Uncertain Value Tradeoffs

Many analyses conducted to inform security decisions depend on estimates of the conditional probabilities of different attack alternatives. These probabilities are difficult to estimate since analysts have limited access to the adversary and limited knowledge of the adversary’s utility function, so subject matter experts often provide the estimates through direct elicitation. In this article, we describe a method of using uncertainty in utility function value tradeoffs to model the adversary’s decision process and solve for the conditional probabilities of different attacks in closed form. The conditional probabilities are suitable to be used as inputs to probabilistic risk assessments and other decision support techniques. The process we describe is an extension of value‐focused thinking and is broadly applicable, including in general business decision making. We demonstrate the use of this technique with simple examples.     

中国农业全要素生产率的再检验——基于省级面板数据农业中间消耗品的分析

提高农业全要素生产率（ATFP）是推进农业高质量发展的必然选择。通过引入农业中间消耗品,利用LP方法测算1999-2016年中国30个省市ATFP,并基于空间杜宾模型分析影响ATFP的关键因素。主要研究结论包括：ATFP对数值集中在[6.0,6.5]区间,总体呈现上升趋势,且存在σ收敛;全局Moran's I指数低于0,即ATFP呈现空间负相关关系,其空间集聚效应减弱,但分布格局相对稳定;大部分省市ATFP的增长率总体呈现先升后降的变化趋势,部分省份明显存在多个峰值,尤以西部地区的省市最为明显;农村人力资本及农村金融发展水平对ATFP的影响系数显著为正,但仅农村人力资本的空间交互作用对本地区的影响显著,即农村人力资本有助于提升邻近地区的ATFP;农业地位、农业内部经济结构及农田受灾率的系数显著为负,但仅农业内部经济结构的空间溢出作用显著。

三国争夺中间地带少数民族述论

魏蜀吴三国为了实施中间地带战略,对处于中间地带上的少数民族采用军事、政治手段展开了激烈的争夺。中间地带上的少数民族为了自己的生存与发展,依违于各政权之间,在一定程度上影响了三国争夺中间地带的结局。

Log-efficient search for significant inputs of linear model

This paper is concerned with the search for an unknown s-tuple A of significant inputs in a linear model with t random discrete carriers and finitely supported i.i.d. noise. We study the decision based on s maximal values of Shannon information between various input and the output N-sequences. It was studied in Malyutov and Sadaka (Random Oper. Stochastic Equations 6 (4) (1998) 339) (abbreviated as MS98) as one of two nonparametric decisions introduced there inspired by the related study in Csiszár and Körner, Information Theory: Coding Theorems for Discrete Memoryless Systems, Academic Press, New York, NY, 1981. It was shown in MS98 that both decisions have the best asymptotic rates as t→∞ uniformly over arbitrary noise distributions and the set of significant parameters in the corresponding classes of tests. We show here that also provides the best rate of the mean error probability exponential decay (defined in Section 2) among the tests based on separate testing influence of each input to the output sequence for a natural class of random designs. The results of this paper (and MS98 for t→∞) justify the universal optimality of the introduced decisions, when used under random balance designs.
