Food Systems Transformation Kenya Policy Options Lessons
2024/4/1
The International Food Policy Research Institute (IFPRI), a CGIAR Research Center established in 1975, provides research-based policy solutions to sustainably reduce poverty and end hunger and ma...
The Influence from the Past: Organizational Imprinting and Firms’ Compliance with Social Insurance Policies in China
Social insurance provision for workers Organizational imprinting Institutional logics
2016/1/26
Using a nationwide survey of randomly selec-ted manufacturing firms in representative Chinese cities,we examine how firms’ compliance with social insurance policies is shaped by their historical impri...

A Decision-making Perspective to Negotiation: A Review of the Past and a Look into the Future
Decision Making Ethics Negotiation Behavior Cognition and Thinking Emotions
2015/4/22
Through the decision-analytic approach to negotiations, the past quarter century has seen the development of a better dialog between the descriptive and the prescriptive, as well as a burgeoning inter...
Čerenkov-like radiation in a binary superfluid flow past an obstacle
Coupling condensate dark soliton whirlpool rotating vortex dipole
2014/12/25
We consider the dynamics of two coupled miscible Bose-Einstein condensates, when an obstacle is dragged through them. The existence of two different speeds of sound provides the possibility for three ...
Spinor Bose-Einstein condensate flow past an obstacle
Spinor bose-einstein condensate macroscopic nonlinear structure vortex ring
2014/12/24
We study the flow of a spinor (F=1) Bose-Einstein condensate in the presence of an obstacle. We consider the cases of ferromagnetic and polar spin-dependent interactions, and find that the system demo...
The Future Has Thicker Tails than the Past: Model Error As Branching Counterfactuals
Fukushima Counterfactual histories Risk management Epistemology of probability Model errors Fragility and Antifragility Fourth Quadrant
2012/11/23
Ex ante forecast outcomes should be interpreted as counterfactuals (potential histories), with errors as the spread between outcomes. Reapplying measurements of uncertainty about the estimation errors...
一种基于变因子梯度型PAST 的递推子空间辨识算法
递推算法 梯度型子空间跟踪 变因子
2014/10/9
针对传统递推子空间算法采用固定遗忘因子而存在易受噪声干扰等问题, 提出一种新的变因子递推子空间辨识算法. 该算法首先引入变因子构造和更新输入输出Hankel 矩阵以及观测向量; 然后利用变因子改进梯度型子空间跟踪算法估计系统的广义能观测矩阵, 并由广义能观测矩阵来估计系统矩阵; 最后运用系统矩阵??的特征值空间欧氏距离信息实现变因子更新步骤, 使算法具有自适应性. 将所提出算法应用于一类时不变系统...
Open Innovation: Past Research, Current Debates, and Future Directions

2011/10/6
The concept of open innovation has recently gained widespread attention. It is particularly relevant now because many firms are required to implement open innovation, despite the difficulties associat...
Fast approximate inference with INLA: the past, the present and the future
Latent Gaussian models Bayesian Integrated Nested Laplace Approximation
2011/6/17
Latent Gaussian models are an extremely popular, flexible class of models. Bayesian inference for
these models is, however, tricky and time consuming. Recently, Rue, Martino and Chopin introduced
th...
The Past and the Future in the Present

2010/12/17
We show how the shared information between the past and future---the excess entropy---derives from the components of directional information stored in the present---the predictive and retrodictive cau...
Perfect simulation using dominated coupling from the past with application to area-interaction point processes and wavelet thresholding
coupling from the past (CFTP) dominated CFTP exact simulation local stability Markov chain Monte Carlo perfect simulation
2010/3/11
We consider perfect simulation algorithms for locally stable point processes
based on dominated coupling from the past, and apply these methods
in two different contexts. A new version of the algori...
