negative studies have a higher burden of proof

Burden of Proof

This paper presents an analysis of the concept of burden of proof in argument. Relationship of burden of proof to three traditional informal fallacies is considered: (i) argumentum ad hominem (ii) petitio principii and (iii) argumentum ad ignorantiam. Other topics discussed include persuasive dialogue, pragmatic reasoning, legal burden of proof, plausible reasoning in regulated disputes, rules ...

Diabetic patients infected with helicobacter pylori have a higher Insulin Resistance Degree

Background: The association of HP and insulin resistance degree (IR) has not been evaluated in the diabetic patients so far. In this study, we evaluated the association between HP seropositivity and the homeostatic model assessment for insulin resistance (HOMA-IR) in diabetic patients. Methods: In this study, 211 diabetic patients admitted to the endocrinology clinic of Shahid Beheshti Hospita...

Burden of Proof, Presumption and Argumentation

The notion of burden of proof and its companion notion of presumption are central to argumentation studies. This book argues that we can learn a lot from how the courts have developed procedures over the years for allocating and reasoning with presumptions and burdens of proof, and from how artifi cial intelligence has built precise formal and computational systems to represent this kind of rea...

Burden of esophageal cancer in Iran during 1995-2015: Review of findings from the Global Burden of Disease studies

Background: Iran is located in Asian esophageal cancer belt, with age-standardized incidence rate (ASR) of approximately 7 per 100,000 for both men and women. To provide potential solution recommendations for achieving accurate estimations regarding the burden of the disease in Iran, we designed a study to assess the burden of esophageal cancer in Iran during 1995-2015 by collecting data from t...
