对贵阳某大桥桥台溶洞的稳定性分析与评价

贵州是我国岩溶地区分布的主要区域之一,在岩溶区处理路桥基础稳定性分析与评价是目前工程建设过程中面临的重点技术难题,尤其在处理大桥桥台溶洞方面,缺乏对溶洞应力应变稳定性的认识。文章以贵阳某大桥桥台溶洞为例,在调查研究区桥台溶洞工程地质环境条件的基础上,通过评价场地溶洞的岩土体力学性质,利用定性和定量两种方法对桥台溶洞进行系统的稳定性分析与评价,从而保证桥台溶洞的稳定性和工程的整体质量。

Physical appearance and earnings: further evidence

The literature contains numerous studies on earnings differentials based on age, race, and gender. Comparatively few studies have examined differences in labour market success related to physical appearance. Using three waves of data collected at two organizations, this paper tested for earnings differentials among workers based on their self-reported appearance. Significant earnings premiums for attractiveness were found for women, but not for men.     

Modelling conditional moments and correlation with the continuous hidden-threshold-skew-normal distribution

A key issue in modelling conditional densities of returns of financial assets is the time-variation of conditional volatility. The classic econometric approach models volatility of returns with the generalized autoregressive conditional heteroscedasticity (GARCH) models where the conditional mean and the conditional volatility depend only on historical prices. We propose a new family of distributions in which the conditional distribution depends on a latent continuous factor with a continuum of states. The distribution has an interpretation in terms of a mixture distribution with time-varying mixing probabilities. The distribution parameters have economic interpretations in terms of conditional volatilities and correlations of the returns with the hidden continuous state. We show empirically that this distribution outperforms its main competitor, the mixed normal conditional distribution, in terms of capturing the stylized facts known for stock returns, namely, volatility clustering, leverage effect, skewness, kurtosis and regime dependence.
