On the strong convergence for weighted sums of ρ *-mixing random variables

A complete convergence result is obtained for weighted sums of identically distributed ρ ^*-mixing random variables with E|X ₁| ^α log(1 + |X ₁|) < ∞ for some 0 < α ≤ 2. This result partially extends the result of Sung (Stat Papers 52: 447–454, 2011) for negatively associated random variables to ρ ^*-mixing random variables. It also settles the open problem posed by Zhou et al. (J Inequal Appl, 2011, doi:10.1155/2011/157816).     

A Strong Limit Theorem for Weighted Sums of Negatively Dependent Random Variables

In this article, we establish a new complete convergence theorem for weighted sums of negatively dependent random variables. As corollaries, many results on the almost sure convergence and complete convergence for weighted sums of negatively dependent random variables are obtained. In particular, the results of Jing and Liang (2008 Jing, B.Y., Liang, H.Y. (2008). Strong limit theorems for weighted sums of negatively associated random variables. J. Theor. Probab. 21:890–909.[Crossref], [Web of Science ®] , [Google Scholar]), Sung (2012 Sung, S.H. (2012). Complete convergence for weighted sums of negatively dependent random variables. Stat. Pap. 53:73–82.[Crossref], [Web of Science ®] , [Google Scholar]), and Wu (2010) can be obtained.     

Transnational migration and the involuntary return of undocumented migrants across the Cambodian–Thai border

ABSTRACT

Migration from Cambodia is a major livelihood strategy for rural communities, with most rural families having at least one, usually younger, member migrating in search of work. The pervasive nature of this phenomenon relates to Cambodia’s troubled political past, and the country’s political economy that structures choice and opportunity. Under-investment in the agrarian economy together with unequal access to credit and productive resources leaves many rural Cambodians with little option but to migrate to boost family income. Thailand is the number one destination for rural Cambodians. Most have an undocumented status, putting them at risk of arrest and deportation. The return of more than 200,000 migrants to Cambodia over a two-week period in 2014 was precipitated by the Thai military’s seizure of power and migrants’ fear of the consequences of political instability, given their still vivid historical memory of the Cambodian Khmer Rouge’s reign of terror during the 1970s. Interviews with Cambodian migrants and members of their families are examined within a wider political and economic context to gain insight into migrants’ motivations and decision-making. The expulsion of migrants from Thailand casts light on the compulsive nature of migration, despite the high risks and precarious conditions under which undocumented migration takes place.     

Correlation analysis of ordered symmetrically dependent observations and their concomitants of order statistics

Given two jointly observed random vectors Y and Z of the same dimension, let Y be a reordered version of Y and Z the resulting vector of concomitants of order statistics. When X is a covariate of interest, also jointly observed with Y, the authors obtain the joint covariance structure of (X, y, Z) and the related correlation parameters explicitly, under the assumption that the vector (X, Y, Z) is normal and that its joint covariance structure is permutation symmetric. They also discuss extensions to elliptically contoured distributions.     

The fatal affinity of the ‘Sonderweg’ revisited: The diffusion of emergency powers in Germany,Japan and Korea (1871–1987)

Many authoritarian regimes in Asia have utilized emergency powers to legitimize their measures of suppressing political opponents and maintaining power. In opposition to previous interpretations that categorize Asian experiences as ‘exceptional cases’ when compared to ‘normal’ Western liberal democracies, this article suggests that this issue should be viewed within the context of the broader ‘affinity’ of the ‘Sonderweg’ phenomenon. The paper compares Germany, Japan and Korea by examining the complex ‘diffusion’ processes of constitutional emergency powers and also by illuminating systemic affinities and fundamental differences. It argues that elites and technocrats in Germany, Japan and Korea exhibited diverging patterns in adopting, filtering and utilizing these constitutional powers.     

Optimal Selection Strategy for the Group Interview Problem

We propose a more generalized version of the secretary problem, called the group interview problem, in which each group contains several alternatives and each group of alternatives is presented and evaluated sequentially over time. Using the assumptions corresponding to the classical secretary problem, we derive an optimal selection strategy which maximizes the probability of winning or selecting the single best choice in a given sequence of groups. We further address the problem of choosing at the beginning of the evaluation process a sequence of groups to maximize the winning probability. Because of formidable computational requirements to obtain an optimal solution to this sequencing problem, we then develop a heuristic algorithm based on several properties inherent in an optimal selection strategy. The heuristic procedure is evaluated experimentally using Monte Carlo simulation and is shown to be effective in obtaining near-optimal (within 5 percent) solutions.     

中国文学史上的"古代"与"近代"

考察整个中国传统文学史,即可发现其文学发展上最突出的特征,就是古时候很长期间,以诗为中心成就盛大的发展,而到某一时期,其发展停滞,显示失去自己文学传统的现象,传统的丧失,自然带来创造和发展能力的丧失.据此如果将中国文学史分为前后两个时期,应称前时期为"古代",后时期为"近代"."古代"转变为"近代"的时期为北宋末年(1126)前后,这时不但在文学,整个中国文化都开始变化.这变化从安史之乱开始发动,发动这变化的是当时中国周边异族的影响与压力.又南宋的新儒学也有反文学反文化的倾向,结果支持这种中国文化的转变.
