We present a principle for introducing new types in type theory which generalises strictly positive indexed inductive data types. In this new principle a set A is defined inductively simultaneously with an A-indexed set B, which is also defined inductively. Compared to indexed inductive definitions, the novelty is that the index set A is generated inductively simultaneously with B. In other wor...

We show that strictly positive inductive types, constructed from polynomial functors, constant exponentiation and arbitrarily nested inductive types exist in any Martin-Löf category (extensive locally cartesian closed category with W-types) by exploiting our work on container types. This generalises a result by Dybjer (1997) who showed that non-nested strictly positive inductive types can be re...

background: today, electronic mass media such as television (tv), influence behavioral patterns of their audiences. this study aimed to evaluate what messages on food advertisements related to oral health were transmitted (appeals) and how they were transferred (performance methods & artistic techniques) in islamic republic of iran broadcasting (irib). methods: in this cross sectional study, br...

background: a few studies have addressed the impact of stoma on patients’ social life. this study aimed to understand the problems leading to social isolation of patients undergoing ostomy. methods: a conventional qualitative content analysis by unstructured interviews was conducted on 27 patients with intestinal or urinary diversion ostomy recruited from the iranian ostomy association (ioa) wi...

The aim of this study was to describe the experiences nursing academics exposure contra-power harassment by under-graduate students. Contra-power students is a growing phenomenon which defined as those ni formal positions power who are not. Harassing behaviours can include verbal, physical and sexual digital through mediums such social media. Cited perpetrated often experienced after release gr...

We propose a method to extract purely functional contents from logical inductive types in the context of the Calculus of Inductive Constructions. This method is based on a mode consistency analysis, which veri es if a computation is possible w.r.t. the selected inputs/outputs, and the code generation itself. We prove that this extraction is sound w.r.t. the Calculus of Inductive Constructions. ...
