Geeta distribution and its properties

A new discrete distribution defined over all the positive integers and with the name of Geeta distribution is described. It is L-shaped like the logarithmic series distribution, Yule distribution and the discrete Pareto distribution but is far more versatile than them as it has two parameters. It belongs to the classes of location parameter distributions, modified power series distributions, Lagrange series distributions and exponential distributions. Its mean fi, variance a2 and two recurrence formulae for higher central moments are obtained. Convolution theorem and variations in the model with changes in the parameters have been considered. ML estimators, MVU estimators and estimators based of mean and variance and on mean and first frequency have been derived.     

An Improved Boxplot for Univariate Data

The boxplot is an effective data-visualization tool useful in diverse applications and disciplines. Although more sophisticated graphical methods exist, the boxplot remains relevant due to its simplicity, interpretability, and usefulness, even in the age of big data. This article highlights the origins and developments of the boxplot that is now widely viewed as an industry standard as well as its inherent limitations when dealing with data from skewed distributions, particularly when detecting outliers. The proposed Ratio-Skewed boxplot is shown to be practical and suitable for outlier labeling across several parametric distributions.     

Bayesian Approaches to Nonparametric Estimation of Densities on the Unit Interval

This paper investigates nonparametric estimation of density on [0, 1]. The kernel estimator of density on [0, 1] has been found to be sensitive to both bandwidth and kernel. This paper proposes a unified Bayesian framework for choosing both the bandwidth and kernel function. In a simulation study, the Bayesian bandwidth estimator performed better than others, and kernel estimators were sensitive to the choice of the kernel and the shapes of the population densities on [0, 1]. The simulation and empirical results demonstrate that the methods proposed in this paper can improve the way the probability densities on [0, 1] are presently estimated.     

On characterizing the normal and poisson distributions

Multivariate normal, correlated multivariate Poisson and multiple Poisson distributions are characterized, in the class of exponential-type distributions, by the properties of the linear combinations of the variables, the properties of their cumulants and the recurance relation between the cumulants.     

Order statistics from the linear-exponential distribution,part I: increasing hazard rate case

For the linear-exponential distribution with increasing hazard rate, exact and explicit expressions for means, product moments and percentage points of order statistics are obtained. Some recurrence relations for both single and product moments of order statistics are also derived. These recurrence relations would enable one to obtain all the higher order moments of order statistics for all sample sizes from those of the lower order     

事实劳动关系探析

事实劳动关系是一种游离于劳动法律关系之外而需要加以特别保护的劳动关系。“事实劳动关系”概念的提出及内涵的不确定性导致了劳动关系领域内的混乱和复杂性。事实劳动关系的本质为无效劳动关系,其本身只有用语上的意义。     

Precarious work: A global perspective

Precarious work is universal, though its forms and consequences vary across countries due to institutional, cultural, and historical differences. This article reviews recent research on precarious work from a global perspective, emphasizing the comparative and interdisciplinary research needed for a comprehensive understanding of the structural transformations in contemporary capitalism that promote precarious work. The article has three foci. First, research that details the diverse forms of precarious work, which have become increasingly heterogeneous as national labor markets have been interwoven with global production networks. Second, research on precarious work that emphasizes its disparate impacts for women, youth, the elderly, racial and ethnic minority groups, and migrants, revealing an articulation of precarity and social cleavages. Third, research on the politics associated with precarious work and how some precarious workers have successfully organized and mobilized their interests, such as by unionizing and becoming involved in electoral politics. Still, questions remain regarding precarious work: how precarious workers differ from regular workers in representing their interests and demands and whether precarious workers are a new, independent social class or remain part of a changing working class. Finally, topics for future research on the global dimensions of precarious work are discussed.

罗兴亚问题对缅-孟关系和地区秩序的影响

罗兴亚问题是一个多世纪前英殖民者在亚洲埋下的诸多“民族问题”之一,也是孟加拉国与缅甸之间难解的“痼疾”。2017年8月以来,罗兴亚问题的再次爆发给相关国家造成巨大冲击。缅甸在打击罗兴亚暴力活动的同时,反对国际干涉,试图牢牢把握该问题解决进程中的主导权,而孟加拉国在政治、安全、经济和社会等不同层面基于自己的利益考量,寻求将罗兴亚人遣返缅甸,立场的对立使两国关系陷入僵局。而美国和印度介入罗兴亚问题则使地区秩序进一步复杂化,并在舆论和安全等领域影响中国的利益。2020年1月17日至18日,中国国家主席习近平应邀对缅甸进行国事访问,标志着中缅经济走廊从概念规划转入实质建设阶段,也给“罗兴亚问题”的解决带来新契机。
