Influence Diagrams ( I D S ) are a graphic formal ism able to provide a compact representation of decision problems. IDs are based on the axioms of probabi l i ty and decision theory, and they define a normat ive framework to model decision mak ing . Unfor tunate ly , IDs require a large amount of in fo rmat ion that is not always available to the decision maker. Th is paper in troduces a new c...

We consider the problem of learning about and comparing the consequences of dynamic treatment strategies on the basis of observational data. We formulate this within a probabilistic decision-theoretic framework. Our approach is compared with related work by Robins and others: in particular, we show how Robins’s ‘G-computation’ algorithm arises naturally from this decision-theoretic perspective....

This research examines the effects of GSS and task type on informational and normative influence in small groups by analyzing group process. It extends Kaplan and Miller' s research on task type and informational and normative influence in small groups in an unsupported setting to a GSS setting. The two tasks used are an intellective task and a preference task, and the two support levels are un...

In their editorial, Tangcharoensathien et al1 describe the challenges of industry market promotion and policy interference from Big Tobacco, Alcohol, and Food in addressing non-communicable diseases (NCDs). They provide an overview of the increasing influence of corporate interest in emerging eco...

Background A free obstetric care policy (FOCP) has been implemented in Morocco in 2008 in order to further decrease maternal mortality.   Methods Through in-depth interviews we explored the perceptions of health professionals in public Moroccan h...

When a new technology is launched, its diffusion becomes an issue of importance. There are various stakeholders that influence diffusion. The question that remains to be determined is their identification and roles. In this paper we outline how the strategies pursued by the government acting as the key stakeholder affected the diffusion of the technology. We base our analysis on a theoretical f...

Employing the Japan-U.S. international survey, this study analyzed the cause of rising perception of the widening income gap in Japan. Between these two countries, their distinct value judgments on the substance of gap influence their recognition. Japanese have negative perception of the income gap caused by talent, academic background or luck; it seems relatively weak in the U.S. A large porti...

A hybrid model, combining influence diagrams and a multicriteria method, is presented in order to assist with the decision making process about which questions would be more attractive to the definition of the diagnosis of Alzheimer’s disease, considering the stages of Clinical Dementia Rating. The modeling and evaluation processes were carried out through a battery of standardized assessments ...
