Let X = {X1, X2, …} be a sequence of independent but not necessarily identically distributed random variables, and let η be a counting random variable independent of X. Consider randomly stopped sum Sη = ∑ηk = 1Xk and random maximum S(η) ? max?{S0, …, Sη}. Assuming that each Xk belongs to the class of consistently varying distributions, on the basis of the well-known precise large deviation principles, we prove that the distributions of Sη and S(η) belong to the same class under some mild conditions. Our approach is new and the obtained results are further studies of Kizinevi?, Sprindys, and ?iaulys (2016) and Andrulyt?, Manstavi?ius, and ?iaulys (2017). 相似文献
This article examines the lack of gender diversity in senior management positions in professional staff in universities. These results are analysed via a Bourdieusian analysis of economic, social, cultural and symbolic capital. Through a purposeful sample of senior professional staff working in universities in three countries: Australia, Canada and the UK, six career‐enhancing strategies needed for career success were determined. The article critiques the resource‐based view of career capital and argues that capitals accumulation for career success can be understood by considering the concepts of symbolic violence and habitus as a way of understanding intra‐cohort differences. It proposes that by considering both the subjective and objective cultural constructs via habitus, and by acknowledging the importance of symbolic capital and symbolic violence towards women, this may be one way of increasing female representation in senior management. 相似文献
China implemented the two-child policy in 2016, however, potential impacts of this new policy on its population reality have not been adequately understood. Using population census data and 1% population sampling data during the period of 1982–2015, this study develops a fertility simulation model to explore the effects of the two-child policy on women’s total fertility rate, and employs Cohort Component Method in population projections to examine China’s demographic future with different fertility regimes. The fertility simulation results reveal that the two-child policy will make significantly positive effects on China’s total fertility rate through increasing second births, leading to a sharp but temporary increase in the first 5 years after the implementation of the new policy. In addition, population projections using simulated total fertility rates show that the Chinese population would reach its peak value around the middle 2020s and be faced with the reduction of labor force supply and rapid aging process, featured with remarkable increases in both size and share of the elderly population. The findings suggest that the two-child policy would undoubtedly affect China’s fertility rates and demographic future; however, the effects are mild and temporary.
