Using the five available waves of the Wage Structure Survey data, this study employs quantile decomposition to investigate the existence of a glass ceiling among Korean professionals. The decomposition results for all professional workers show an inverse U-shape, which implies no evidence of a glass ceiling. However, we find a monotonically increasing pattern for arts and culture professionals, indicating strong evidence of a glass ceiling on their labour market. This result implies that, as the wage quantile moves from lower to higher levels, female professionals in arts and culture jobs face significant barriers to career advancement. This analysis supports the recent assertion of UNESCO that gender equality in culture is not immune to inequalities and discrimination. 相似文献

本文从数理统计入手,给出了玻壳生产中更换产品前后合格率的关系公式,并和实际统计值进行了比较,有较好的符合,为科学量化分析提供了工具。并据此分析,不同尺寸的玻壳产品,当池炉系统的质量水平下降时,它们的合格率的差别也在扩大,并量可能会使得原先利润相对高的产品变得利润相对低。通过合理地计划产品品种的生产,可以获得更多的利润,降低单位成本。同时也阐明原有的新产品质量目标设定方法的不合理性,给出了质量目标设定的科学依据。 相似文献

This study examines the relationship between academic performance and workplace position. Academic performance is measured by undergraduate grade point average (GPA). A series of ordered probit regression models are estimated to isolate the impact of undergraduate GPA on the probability that female and male graduates from the same university hold middle or upper management jobs within their companies. After all potential heterogeneity and explanatory variables are controlled for, results of the pooled regression models suggest that women are less likely to hold both middle and upper management positions. Further analysis also suggests that lower GPA significantly decreases the probability that women hold these positions, while GPA seems to have no significant impact on workplace position for men. Moreover, most factors which positively impact the probability that women attain these positions also benefit men more at the highest level. 相似文献
