Uniform asymptotic linearity of a process based on a signed rank statistic

Consider the process with, cf. (1.2) on page 265 in B1, X₁, …, X_N a sample from a distribution F and, for i = 1, …, N, R${}_{\text{|x}{}_{\text{1}}\text{, - q}{}_{\text{1}}\text{ø|}}$ , the rank of |X₁ - q₁ø| among |X₁ - q₁ø|, …, |X_N - q_Nø|. It is shown that, under certain regularity conditions on F and on the constants p_i and q_i, T^ø_N(t) is asymptotically approximately a linear function of ø uniformly in t and in ø for |ø| ≤ C. The special case where the p_i and the q_i, are independent of i is considered.     

Analytical network process for software selection in product development: A case study

Application of software for manufacturing processes is one of the resolutions many enterprises have resorted to in the 21st century. This has been a result of increased complexity of products, globalization, rapid changes in technology and so on. The idea was that application of software especially for product development would increase the competitive advantage of industry nevertheless the irony has been that most of the investment in software has not achieved the expected results. We carry out a case study to introduce a methodology, the analytical network process as a multiattribute strategic decision making approach to help in the selection of appropriate software to suit the product development process of a particular product.     

现代信用风险度量模型的实证比较与适用性分析

本文通过实证比较分析发现,现代信用风险度量模型对银行贷款的违约率、贷款损失和损失率的预测结果的差异性较大;但信用监测模型和信用风险附加法所预测的经济资本配置比例不仅符合巴塞尔协议对银行贷款经济资本的要求,也略大于实际应该配置的比例,实证表明了它们对度量我国商业银行贷款组合的信用风险具有较好的适用性.此外,本文也充分验证了借款人信用等级的不同,银行贷款经济资本配置的比例会有显著性的差异.

基于发展新理念的粮食类家庭农场成长绩效测评研究

基于发展新理念对粮食类家庭农场成长绩效的评价指标进行理论遴选后,借助专家评审和鉴别力分析进行指标筛选,构建了具有较高信度和效度的评价指标体系。以华北平原五省的453户粮食类家庭农场为样本,采用AHP-模糊综合评价模型,对指标体系做了应用研究。结果表明：粮食类家庭农场成长绩效虽在总体上处于中等偏上水平,但个体间存在一定的成长绩效差异;经济绩效整体表现良好,创新绩效却较低。因此,应引导粮食类家庭农场平衡性成长、制定精准扶持方略和建立成长绩效监测体系。     

如何建立社区支持农业中的消费者信任——惠州四季分享有机农场的个案研究

信任对 CSA 经济的可持续至关重要。 文章基于信任建立过程和信任发展的阶段性理论,通过单案例的研究方法探讨如何构建社区支持农业中的消费者信任。 研究结果表明:消费者信任的建立分为初始信任与持续信任两个阶段。 在潜在消费者的初始信任阶段,直接或间接关系、公开的信息、农 场主特征和消费体验会引发消费者的计算过程、转移过程、预测过程、意图过程和能力过程而建立消费 者初始信任。 在会员的持续信任阶段,用户体验和社会联系会引发消费者的预测过程和意图过程而维 持会员对农场的信任。     

From victims to winners: strategies of negotiation among relocated residents in demolition-compensation events in local China

It has been well documented by researchers that in China’s continual quest for modernisation and urbanisation, many urban and rural residents became displaced and portrayed as victims. A more important question however needs to be explored: do evicted residents learn from others to develop strategies to protect themselves from becoming victims? Through in-depth interviews, primary data collection, documentary research, this study has confirmed that for some evicted residents in Southern China’s urban fringes, when their land was appropriated by local government and developers and they were offered resettlement elsewhere, they did not behave passively to accept the terms of compensation dictated. Instead, they actively learnt from other dwellers who were evicted earlier to become well-organised, resourceful, and sophisticated negotiators in bargaining for their compensation. The group of rural residents proved that they could do better than the evicted urban residents, especially in terms of compensation-negotiation.     

西方人类学农民研究综述

农民研究包含了人类学关注的所有多样性和复杂性特征。 在资本主义全球化背景下,农民概念中的复杂性使得对其进行具体分类和厘清尤为必要。 文章通过对国外人类学农民概念及农民研究的梳理,呈现出人类学农民研究的三个重要阶段:对农民的定义经历了从模糊到清晰,从清晰到逐渐被消解,以及当下再小农化的历史进程。 总体而言,农民研究主要围绕文化和政治经济两个方向展开。20世纪以来,农民以不同的形式融入更广泛的社会组织中,农业正在以农民的方式日益重组。     

Moment‐Independent Sensitivity Analysis Using Copula

In risk assessment, the moment‐independent sensitivity analysis (SA) technique for reducing the model uncertainty has attracted a great deal of attention from analysts and practitioners. It aims at measuring the relative importance of an individual input, or a set of inputs, in determining the uncertainty of model output by looking at the entire distribution range of model output. In this article, along the lines of Plischke et al., we point out that the original moment‐independent SA index (also called delta index) can also be interpreted as the dependence measure between model output and input variables, and introduce another moment‐independent SA index (called extended delta index) based on copula. Then, nonparametric methods for estimating the delta and extended delta indices are proposed. Both methods need only a set of samples to compute all the indices; thus, they conquer the problem of the “curse of dimensionality.” At last, an analytical test example, a risk assessment model, and the levelE model are employed for comparing the delta and the extended delta indices and testing the two calculation methods. Results show that the delta and the extended delta indices produce the same importance ranking in these three test examples. It is also shown that these two proposed calculation methods dramatically reduce the computational burden.
