A Bayesian Model and Stochastic Exposure (Dose) Estimation for Relative Exposure Risk Comparison Involving Asbestos‐Containing Dropped Ceiling Panel Installation and Maintenance Tasks

Assessing exposures to hazards in order to characterize risk is at the core of occupational hygiene. Our study examined dropped ceiling systems commonly used in schools and commercial buildings and lay‐in ceiling panels that may have contained asbestos prior to the mid to late 1970s. However, most ceiling panels and tiles do not contain asbestos. Since asbestos risk relates to dose, we estimated the distribution of eight‐hour TWA concentrations and one‐year exposures (a one‐year dose equivalent) to asbestos fibers (asbestos f/cc‐years) for five groups of workers who may encounter dropped ceilings: specialists, generalists, maintenance workers, nonprofessional do‐it‐yourself (DIY) persons, and other tradespersons who are bystanders to ceiling work. Concentration data (asbestos f/cc) were obtained through two exposure assessment studies in the field and one chamber study. Bayesian and stochastic models were applied to estimate distributions of eight‐hour TWAs and annual exposures (dose). The eight‐hour TWAs for all work categories were below current and historic occupational exposure limits (OELs). Exposures to asbestos fibers from dropped ceiling work would be categorized as “highly controlled” for maintenance workers and “well controlled” for remaining work categories, according to the American Industrial Hygiene Association exposure control rating system. Annual exposures (dose) were found to be greatest for specialists, followed by maintenance workers, generalists, bystanders, and DIY. On a comparative basis, modeled dose and thus risk from dropped ceilings for all work categories were orders of magnitude lower than published exposures for other sources of banned friable asbestos‐containing building material commonly encountered in construction trades.     

The Gender Pay Gap in the US: Does Sector Make a Difference?

Analyses of data from the 2000 US Census show that the gender pay gap differs by sector of employment and according to the part of the earnings distribution that is considered. The gender pay differential in the private sector in the US does not display either the glass ceiling or sticky floor effects that have been reported for many other countries. The government sector is, however, characterized by a distinct sticky floor effect in the female–male pay differential. Regardless of the sector of employment, females have lower hourly rates of pay than men across the entire earnings distribution.

Item count technique with no floor and ceiling effects

Abstract

Conclusions of sample surveys dealing with matters of privacy are often disputed. Many people either refuse to participate or provide false answers. Indirect questioning techniques are designed so that reliable estimates can be produced while the privacy of the participants is protected. One such method, the Item Count Technique is gaining increasing popularity. However, the original version of the method does not fully protect the privacy of the participants. In this paper we propose a new version of the technique which better protects the privacy of the respondents and does not have the so-called floor and ceiling effects.     

玻璃天花板下的守望——A大学女教师工作满意度研究

从社会性别视角切入,通过对研究型大学367名专任女教师的工作满意度进行了问卷调查,结果显示教师工作满意度存在一定性别差异,表现在女性对校园学术环境、国际化、人际关系等方面较男性满意,但在课题经费的获得、课题的获批、接触学术前沿等研究资源获得方面远不如男性教师。此研究表明缺乏学术资源是女性职业生涯发展中"玻璃天花板"的构成之一。

Lawyers’ Professional Careers: Increasing Women's Inclusion in the Partnership of Law Firms

Despite a huge increase in the number of women lawyers employed in professional service firms (PSFs) over the last four decades, the proportion of women at partnership level has changed at a much slower rate. This article investigates men's and women's understandings of women's careers and promotion to equity partner. The findings show that one reason why few women advance to equity partner level is that both men and women understand this role as requiring them to privilege work considerations over family. We recommend that PSF researchers and practitioners reflect more on the management of diversity and alternative work arrangements and organization.
