Strong Limit Theorems for Pairwise NQD Random Variables

A number of strong laws of large numbers for sequences of pairwise negative quadrant dependent (NQD) random variables have been established by using the generalized three series theorem. In this article, we obtain a strong law of large numbers by using the truncation technique and method of subsequences instead of the generalized three series theorem. Our result generalizes and improves on the corresponding one in Li and Yang (2008 Li , R. , Yang , W. ( 2008 ). Strong convergence of pairwise NQD random sequences . J. Math. Anal. Appl. 344 : 741 – 747 .[Crossref], [Web of Science ®] , [Google Scholar]). We also obtain a complete convergence result for an array of rowwise pairwise NQD random variables.     

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).     

Complete convergence for weighted sums of negatively dependent random variables

In this paper, we obtain a complete convergence result for weighted sums of negatively dependent random variables under mild conditions of weights. This result generalizes and improves the result of Zarei and Jabbari (Stat Papers doi:, 2009). Our result also extends the result of Taylor et al. (Stoch Anal Appl 20:643–656, 2002) on unweighted average to a weighted average.     

Drivers of Corporate Social Responsibility Attitudes: The Demography of Socially Responsible Investors

Demographic characteristics of socially responsible investors (SRIs) are likely to play a significant role in shaping their perceptions and behaviour concerning corporate social responsibility (CSR). This paper identifies demographic characteristics of SRIs and explores the relationship of these characteristics with their CSR attitudes. We analyse, using generalized ordered logistic regression, the questionnaire responses of 2464 SRIs from 20 countries. The results demonstrate that younger and female SRIs are more likely to believe that a company's social and environmental performance is as important as its financial performance. Female SRIs and those with high incomes are the most likely to believe that companies should be as responsible to their shareholders as to the broader society. In addition, younger SRIs, those with high incomes and those who have attained higher education levels regard socially responsible companies as at least as profitable as other companies. The benefits which companies can derive from understanding the demographic profile of SRIs are examined, including a potentially lower cost of capital, improved CSR rankings and business policy formulation and communication consistent with CSR views held by specific groups of SRIs.

On D-optimal robust second order slope-rotatable designs

Das and Park (2006) introduced slope-rotatable designs overall directions for correlated observations which is known as A-optimal robust slope-rotatable designs. This article focuses D-optimal slope-rotatable designs for second-order response surface model with correlated observations. It has been established that robust second-order rotatable designs are also D-optimal robust slope-rotatable designs. A class of D-optimal robust second-order slope-rotatable designs has been derived for special correlation structures of errors.     

The Enhanced Double Digest Problem for DNA Physical Mapping

The double digest problem is a common NP-hard approach to constructing physical maps of DNA sequences. This paper presents a new approach called the enhanced double digest problem. Although this new problem is also NP-hard, it can be solved in linear time in certain theoretically interesting cases.     

Information theoretic approaches to income density estimation with an application to the U.S. income data

The size distribution of income is the basis of income inequality measures which in turn are needed for evaluation of social welfare. Therefore, proper specification of the income density function is of special importance. In this paper, using information theoretic approach, first, we provide a maximum entropy (ME) characterization of some well-known income distributions. Then, we suggest a class of flexible parametric densities which satisfy certain economic constraints and stylized facts of personal income data such as the weak Pareto law and a decline of the income-share elasticities. Our empirical results using the U.S. family income data show that the ME principle provides economically meaningful and a very parsimonious and, at the same time, flexible specification of the income density function.
