The random index is a strictly stationary renewal counting process generated by some negatively associated random variables. Using a revised large deviation result of partial sums, the elementary renewal theorem and the central limit theorem of negatively associated random variables, a precise large deviation result is derived for the random sums. The result is applied to the customer-arrival-based insurance risk model. Some uniform asymptotics for the ruin probabilities of an insurance company are obtained as the number of customers or the time tends to infinity.展开更多

Firstly, it examines Dexter＇s final twist in plot and the decision Dexter makes to finally embrace his ＂dark passenger＂ to argue for the necessity of the plot twist to the series, which scholarship has not yet performed. Secondly, by situating Dexter＇s decision within a framework focused on reproductive futurism, a revised and more nuanced approach to Dexter＇s ontological dilemma can be proffered. Finally, by locating Dexter＇s dark passenger within the theoretical frames of reproductive futurism and community this article adds an important dimension to notions of the monster conventionally rooted in theories of identity and subjectivity. In the final moments of the series everything changes for Dexter as his identity is redeemed for a reproductive future without guarantees, which this article argues is germane to considerations ofbiopolitics and community in the contemporary period.展开更多

文摘The differences between two sequences of nonnegative independent and identically distributed random variables with sub-exponential tails and the random index are studied. The random index is a strictly stationary renewal counting process generated by some negatively associated random variables. Using a revised large deviation result of partial sums, the elementary renewal theorem and the central limit theorem of negatively associated random variables, a precise large deviation result is derived for the random sums. The result is applied to the customer-arrival-based insurance risk model. Some uniform asymptotics for the ruin probabilities of an insurance company are obtained as the number of customers or the time tends to infinity.
