The problem of parameter estimation and statistical inference when fitting an M/G/∞ queuing process to data is considered in the situation where the times of arrival and departure are unknown; instead recurrent events, which occur according to a mixed Poisson process, are observed between the times of arrival and departure.

The paper attempts to examine whether subsidiaries from different countries-of-origin differ with respect to their financial structures and performance in the same host country and whether greater foreign control affects their financing patterns and financial performance. The results show that Japanese firms differ significantly with respect to their financial structures from the Indian firms a...

As listed in the DSM-IV-TR, the essential features of panic disorder are "the presence of recurrent, unexpected Panic Attacks, followed by at least 1 month of persistent concern ... or a significant behavioral change related to the attacks" (American Psychiatric Association, 2000). Panic disorder is characterized by instances of an intense sense of impending doom in which many patients will fee...

Motivated by counterparty and credit risk applications, we define an invariant time as a stopping time such that local martingales with respect to a smaller filtration and a possibly changed probability measure, once stopped right before that time, are local martingales with respect to the original model filtration and probability measure. The possibility to change the measure provides an addit...

Surprisingly, to the eyes of many experts, the draft of DSM‐5 better captures the essence of narcissistic personality disorder (NPD) than previous versions did. Many clinicians (myself included) were dissatisfied with the descriptions of NPD in earlier versions of DSM. Persons with NPD are aggressive and boastful, overrate their performance, and blame others for their setbacks; current editions...

Historians of science Naomi Oreskes and Erik Conway, authors of Merchants of Doubt, have written a new book as ambitious as it is concise. The Collapse of Western Civilization: A View from the Future is told from the perspective of a Chinese historian several centuries in the future, looking back at our current time and attempting to explain to readers the irrationality of our behavior. In the ...

Secondary trauma is defined as indirect exposure to trauma through a firsthand account or narrative of a traumatic event. The vivid recounting of trauma by the survivor and the clinician's subsequent cognitive or emotional representation of that event may result in a set of symptoms and reactions that parallel PTSD (e.g., re-experiencing, avoidance and hyperarousal). Secondary traumatization is...

In many real-time systems, the workload can be characterized as a set of jobs with linear precedence constraints among them. Jobs often have variable execution times and arbitrary release times. We describe here three algorithms that can be used to compute upper bounds on completion times of such jobs scheduled on a priority-driven basis. The algorithmshave different performance and complexity....
