How does distance affect market entry mode choice? Evidence from French companies

The objective of this article is to examine the relevant dimensions of distance for foreign market entry mode choice. Based on a sample of 203 interfirm linkages formed by French multinationals with partners across the world, we analyze the impact of four dimensions of distance on the choice between cooperative alliances and mergers-acquisitions. The findings indicate that administrative and economic distance have a significant influence on market entry mode choice, whereas the impact of cultural and geographic distance is not significant. They further highlight the important role of the host country's government effectiveness for market entry mode decisions.

略论现代远程教育中素质教育的实现途径

现代远程教育具有独特的教与学模式、教学管理模式和运行机制。现代远程教育领域实施素质教育,在教育理念及实现途径上,都必须考虑到技术层面的因素、学习者的特征、教与学模式的特点。为此,必须重点把握如下环节:确定素质教育的重点内容,创设基于计算机网络的学习环境,确立专业教育和课程教学在素质教育中的主渠道作用,创新教与学模式,探索有效的实践教学方式,营造富有特色的校园文化,建立科学的评价体系。     

Independence test in high-dimension using distance correlation and power enhancement technique

Abstract

This paper is concerned with independence test in high-dimension. A new test statistic is proposed with two terms: one is based on the modified distance correlation statistic, the other is constructed to enhance the power under sparse alternatives. Asymptotic properties of the test statistic are discussed under some regular conditions. The finite-sample simulations exhibit its superiority over some existing procedures. Finally, a real data example illustrates the proposed test.     

网络沟通下政府形象“距离悖论”的解析及应对

网络沟通的兴起,使政府形象塑造的环境发生了变化,政府形象的“距离悖论”出现新特点,其突出表现是,民众对政府形象的评价与该级政府同民众的距离（包括空间距离和时间距离）成反比。在网络沟通下,形象良好的政府须具有回应性,倡导科技领先,强调参与和协作以及具有预见性,因此,政府应从树立形象意识、完善电子政府工程、提升政府媒体公关能力和公信力以及提高危机处理能力等方面着手,来应对政府形象的“距离悖论”,以塑造良好的自身形象。     

A weighted Harrell–Davis distance test with applications to censored data

Consider the standard treatment-control model with a time-to-event endpoint. We propose a novel interpretable test statistic from a quantile function point of view. The large sample consistency of our estimator is proven for fixed bandwidth values theoretically and validated empirically. A Monte Carlo simulation study also shows that given small sample sizes, utilization of a tuning parameter through the application of a smooth quantile function estimator shows an improvement in efficiency in terms of the MSE when compared to direct application of classic Kaplan–Meier survival function estimator. The procedure is finally illustrated via an application to epithelial ovarian cancer data.     

新生代农民工与城市居民的社会距离分析

本文运用2008年宁波城市新生代农民工调查数据,对新生代主体视角下与城市居民社会距离的现状及影响凶素进行了探讨。分析结果发现：以新生代农民工为主体视角的社会距离建立在融入意愿和排斥预期两个层面基础上;与上一代农民工相比．新生代农民工与城市居民的社会距离在增大。社会经济地位、社会关系网络、居住空间和社会文化会显著影响新生代农民丁的社会距离。要促进新生代农民丁的城市融人,缩短新生代农民工与城市居民的社会距离,需要新生代农民工、城市居民、政府和社会等多方行动者的共同努力。     

Distance graphs on R n with 1-norm

Suppose S is a subset of a metric space X with metric d. For each subset D⊆{d(x,y):x,y∈S,x≠y}, the distance graph G(S,D) is the graph with vertex set S and edge set E(S,D)={xy:x,y∈S,d(x,y)∈D}. The current paper studies distance graphs on the n-space R ₁ ⁿ with 1-norm. In particular, most attention is paid to the subset Z ₁ ⁿ of all lattice points of R ₁ ⁿ . The results obtained include the degrees of vertices, components, and chromatic numbers of these graphs. Dedicated to Professor Frank K. Hwang on the occasion of his 65th birthday.

Distance education and international social work education

As a result of the development of new communication technology, distance education has become a rapidly growing area over the last few decades. Market and commercial pressures are major factors in its developing impact. Distance education has also been applied to social work education. Because it is a small field it may be both positively and negatively affected. Social work education requires face-to-face communication training. Educators need to respond to the limitations of distance education technologies and processes to provide for cultural and linguistic diversity, through openness to joint work across different cultures, anti-standardisation and -discrimination, reflexivity, user control and resources, and cultural and language translation.
