OBJECTIVE Objective measurement of depression remains elusive. Depression has been associated with insecure attachment, and both have been associated with changes in brain reactivity in response to viewing standard emotional and neutral faces. In this study, we developed a method to calculate predicted scores for the Beck Depression Inventory II (BDI-II) using personalized stimuli: fMRI imaging...

Distributed partially observable Markov decision problems (POMDPs) have emerged as a popular decision-theoretic approach for planning for multiagent teams, where it is imperative for the agents to be able to reason about the rewards (and costs) for their actions in the presence of uncertainty. However, finding the optimal distributed POMDP policy is computationally intractable (NEXPComplete). T...

BACKGROUND Bile duct injury (BDI) remains the most serious complication of laparoscopic cholecystectomy (LC). A Swiss database was used to identify risk factors for BDI and to assess the effect of intraoperative cholangiography (IOC). METHODS Data for patients from 114 Swiss institutions who underwent LC for acute or chronic cholecystitis between 1995 and 2005 were used in univariable and log...

This paper provides a theoretical basis for performing time limited planning within Belief-Desire-Intention (BDI) agents. The BDI agent architecture is recognised as one of the most popular architectures for developing agents for complex and dynamic environments, in addition to which they have a strong theoretical foundation. Recent work has extended a BDI agent specification language to includ...

The popularity of agents has given rise to many Agent Architectures. Each of these architectures have different approaches to agency. The approaches have different strengths and weaknesses in the support they provide for different aspects of agency. This paper compares the support provided by two Agent Architectures, JACK Intelligent Agents and the Open Agent Architecture, for BDI Agents, Teamw...

This paper presents four requirements for BDI-based agent programming languages to facilitate the implementation of autonomous robot control systems. The first requirement is to support the integration of these languages with robotic frameworks. The second requirement is real-time reaction and response to events. The real-time reactivity problem in the BDI architecture is discussed and a distri...

The psychometric properties of the Beck Depression Inventory-II (BDI-II) are well established with primarily Caucasian samples. However, little is known about its reliability and validity with minority groups. This study evaluated the psychometric properties of the BDI-II in a sample of low-income African American medical outpatients (N=220). Reliability was demonstrated with high internal cons...

This study has evaluated depression in patients with episodic migraine (n=98), chronic migraine without medication overuse (n=23), and chronic migraine with medication overuse (n=57). The Beck Depression Inventory (BDI) was used to evaluate depressive symptoms in these three groups. The mean BDI score obtained in all patients was higher than that observed in asymptomatic subjects (episodic migr...

When developing BDI agent-based systems, some design patterns such as incompatible intentions, multiple strategies, intention decomposition, etc. would be very useful for specifying some desired agent behaviours. As BDI agent programmers, our desire would be to have a framework that natively supports such common patterns. The PRACTIONIST framework provides a goal-oriented approach for developin...
