Measuring and framing support for universal basic income

We execute an original survey experiment to examine the extent and determinants of support for a nascent policy issue, universal basic income (UBI), in the American public. We explore the effects of how UBI is framed (either in the context of values or the context of policy), finding three key results. First, UBI is primarily a Democratic and liberal policy. Second, negative arguments against UBI move support for UBI more than positive arguments. Third, and surprisingly, respondents are equally affected by both policy-driven and value-driven arguments about UBI. In conclusion, an increase in messaging about UBI is likely to widen existing partisan differences in UBI support. These differences are unlikely to be won over by policy or values arguments.     

Characterization of singular balanced fractional sm factorial designs derivable from balanced arrays with maximum number of constraints

An upper bound on the maximum number of constraints for s-symbol balanced arrays is derived. It is shown that balanced fractional s^m factorial designs derived from some balanced arrays with the maximum possible number of constraints become singular.     

Optimal designs for additive mixture model with heteroscedastic errors

This paper presents a study of D- and A-optimality of direct sum designs for additive mixture models when the errors are heteroscedastic. Sufficient conditions are given so that D- and A-optimal designs for additive mixture models can be constructed from the D- and A-optimal designs for homogeneous models in sub-mixture systems.     

“是”字句的节律特征和语音停延规律

关于"是",语法学界已颇有研究.但不少语言学家只强调其语法关系,而忽视了"是"的语音形式和表意功能.通过考察可发现:"是"的节律特征不同表示不同的语义.通过对"是"字句所做的语音测试和录音,以及对"是"字句的语音切分进行分析和归纳后,还可以发现"是"字句具有与一般认识不完全一致的语音停延规律.

浅议数学实验的教学价值

数学实验教学就是指恰当地运用数学实验,创设问题情境,引导学生参与实践、自主探索、合作交流,从而发现数学问题、提出猜想、验证猜想和创造性地解决数学问题的一种全新的教学活动．在中学数学课堂教学中,根据教学内容编排和学生学习的需求,适度地进行数学实验教学,有助于培养学生合情推理、改变学生的学习方式、突破教学的难点、培养学生探究和创新精神、培养学生的应用意识以及对数学思想方法的理解和掌握．     

Testing Theories of Choice Under Risk: Estimation of Individual Functionals

The method introduced here allows us to use a data set with a non-restricted number of outcomes, here 21. Hence, our method complements the other ones developed in the domain of the probability triangle. Individual parameters are estimated for expected utility and various non-expected utility theories. We use CRRA and CARA utility functions, both without and with the assumption of weakly concavity. Rank-dependent utility, prospective reference and cognitive consistency theories emerge from the others.An erratum to this article can be found at
