随机通货膨胀下DB养老金计划最优退出策略

针对目前投保人在投保过程遇到的系统性风险,研究了基于随机通货膨胀风险下DB养老金计划的最优退出策略问题。该计划具有最低保障功能,并且投保人可以在任何时期行使surrender期权。为了找到行使surrender期权的最佳时间,将带有surrender期权的DB型年金计划的最佳退出时间转化为一个自由边界问题,由此可以得到一个相应的非齐次偏微分方程,利用梅林变换对非齐次偏微分方程进行积分变换后使用RIM递推积分法对积分方程进行数值求解,从而得到一个surrender期权估值的积分方程和最优退出边界。研究表明:这种期权为投保人提供了更多的保护,使得投保人拥有更多的选择权;此外,用数值分析给出了公平收费率的性质和在不同投资比例对账户价值的影响以及其最优退出策略。

University Social Responsibility from the Perspective of the Different Stakeholders

The objective of this research is to analyze social responsibility from the stakeholder’s perspective to establish whether universities have advanced in their conception. The research is exploratory and conclusive descriptive of the cross-sectional sample. The internal and external stakeholders of the public universities domiciled in Quito were taken into account. The results showed that university managers relate this concept with actions of connection with community, the relevance of the academic offer and the accountability, while students relate this concept with teaching in values and philanthropic activities. For administrative personnel instead, university social responsibility （USR） is related to work benefits. On the other hand, the business sector relates this concept with the answer to their needs of innovation. As expected, representatives of government agencies highlight the university’s responses that are necessary to become the engine of economic, productive and social transformation of the country. It is concluded that USR is applied in a partial way, which translates into management models that do not incorporate it as an explicit variable of their actions.

Determination of Correction Values of Operating Reliability of Assembly Components of the Assembly—Front Spinner Spinning Box (R1 Rieter) on the Basis of Operating Data

The optimal safety model includes the values of the operation of the components with the allowed risk, and it is clearly seen that the belt of absolutely safe operation of the analyzed circuit is located between the values of the displayed dependence curves Mξ(t)BP = f(t). AND also, analyses have been carried out to ensure the flawless operation of the OE machine and the consistency of product quality.
