When culture and ethics meet: Understanding the dynamics between cultural dimensions,moral orientations,moral inequity,and commitment in the context of corporate misconduct allegations

This study explored the associations between individuals' cultural orientations, moral orientations, perceived moral inequity, and commitment to an organization accused of misconduct. An online survey was conducted among Singapore citizens (N = 477), exposing the participants to a fictitious vignette that included allegations of child labor abuse practices by their preferred company to understand their reactions to these allegations. Data analyses that individuals who report power distance also believe in consequentialism. There was a negative association between power distance and deontological thinking about how businesses should behave. People with high level of collectivism showed both consequentialist and deontological orientation. Whereas deontologists perceived the alleged misconduct as unethical, individuals with consequentialism did not. Consequentialists were willing to commit to their relationship with the organization despite the allegation. Finally, perceived moral inequity was negatively associated with commitment and fully mediated the relationship between deontology and commitment. Theoretical and empirical implications are discussed (150 words).

Identification and classification of multiple outliers,high leverage points and influential observations in linear regression

Detection of multiple unusual observations such as outliers, high leverage points and influential observations (IOs) in regression is still a challenging task for statisticians due to the well-known masking and swamping effects. In this paper we introduce a robust influence distance that can identify multiple IOs, and propose a sixfold plotting technique based on the well-known group deletion approach to classify regular observations, outliers, high leverage points and IOs simultaneously in linear regression. Experiments through several well-referred data sets and simulation studies demonstrate that the proposed algorithm performs successfully in the presence of multiple unusual observations and can avoid masking and/or swamping effects.     

An improved binary randomized response model using six decks of cards

This article purposes the estimation of population proportion of a sensitive attribute through randomized response technique. An efficient estimator is suggested using six decks of cards to randomise the response. Many existing models can now be viewed as the special case of the proposed model. The superiority of the proposed procedure is established through numerical calculation of percentage relative efficiency with prominent competitors. The proposed procedure is also studied under stratified random sampling protocol. In addition, it is shown that, the proposed stratified estimator, performs better in term of efficiency than its only existing two deck stratified competitor.

企业行为与经济增长方式的转变

本文构建了一个企业技术升级的路径选择模型,该模型很好地解释了企业行为在经济增长方式转变中的作用。同时,论证了处于工业化中后期的经济体实现经济增长方式转变的必要性,并分析了增长方式转变的制约因素。企业的技术选择行为决定经济增长方式,企业选择技术进步的方式由产品间技术距离决定,技术距离的临界值大小与成本和价格的变化速度有关。相同的临界值条件下,创新导致的技术进步成功可能性更大。笔者提出了促进创新主导的经济增长方式的转变的相关政策建议。     

The Rate of Convergence of some Asymptotic Expansions for Distribution Approximations via an Esseen Type Estimate

Some asymptotic expansions not necessarily related to the central limit theorem are studied. We first observe that the smoothing inequality of Esseen implies the proximity, in the Kolmogorov distance sense, of the distributions of the random variables of two random sequences satisfying a sort of general asymptotic relation. We then present several instances of this observation. A first example, partially motivated by the the statistical theory of high precision measurements, is given by a uniform asymptotic approximation to (g(X + μ _n )) _n∈?, where g is some smooth function, X is a random variable and (μ _n ) _n∈? is a sequence going to infinity; a multivariate version is also stated and proved. We finally present a second class of examples given by a randomization of the interesting parameter in some classical asymptotic formulas; namely, a generic Laplace's type integral, randomized by the sequence (μ _n X) _n∈?, X being a Gamma distributed random variable.     

Estimation procedures for grouped data – a comparative study

Interval-censored data are very common in the reliability and lifetime data analysis. This paper investigates the performance of different estimation procedures for a special type of interval-censored data, i.e. grouped data, from three widely used lifetime distributions. The approaches considered here include the maximum likelihood estimation, the minimum distance estimation based on chi-square criterion, the moment estimation based on imputation (IM) method and an ad hoc estimation procedure. Although IM-based techniques are extensively used recently, we show that this method is not always effective. It is found that the ad hoc estimation procedure is equivalent to the minimum distance estimation with another distance metric and more effective in the simulation. The procedures of different approaches are presented and their performances are investigated by Monte Carlo simulation for various combinations of sample sizes and parameter settings. The numerical results provide guidelines to analyse grouped data for practitioners when they need to choose a good estimation approach.
