The Gulf cooperation council (GCC) region is considered as "Emerging market" for pharmaceutical export and bilateral trade. The understanding of the regulatory requirements of this region can be beneficial for pharmaceutical export. Some incidents of the year 2008-09, like recession or economic slowdown in highly well-off and regulated market of the EU and US, raised the demand for alternate de...

This paper describes the usage of Natural Language Processing tools, mostly probabilistic topic modeling, to study semantics (word correlations) in a collection of Persian poems consisting of roughly 18k poems from 30 different poets. For this study, we put a lot of effort in the preprocessing and the development of a large scope lexicon supporting both modern and ancient Persian. In the analys...

BACKGROUND Reliability and validity are the key concepts in measurement processes. Young internet addiction test (YIAT) is regarded as a valid and reliable questionnaire in English speaking countries for diagnosis of Internet-related behavior disorders. OBJECTIVES This study aimed at validating the Persian version of YIAT in the Iranian society. PATIENTS AND METHODS A pilot and a cross-sect...

BACKGROUND Cerebrovascular disease leading to stroke is the most common cause of aphasia. Speakers with agrammatic non-fluent aphasia have difficulties in production of movement-derived sentences such as passive sentences, topicalized constituents, and Wh-questions. To assess the production of complex sentences, some passive, topicalized and focused sentences were designed for patients with non...

BACKGROUND The Arthritis Impact Measurement Scales 2 (AIMS2) has not been translated and validated for Persian-speaking patients with osteoarthritis of the knee. This was to provide a validated instrument to measure functional disability and health-related quality of life in patients with osteoarthritis of the knee in Iran. The aim of this study was to culturally adapt and validate the AIMS2 fo...

FarsiSum is an attempt to create an automatic text summarization system for Persian. The system is implemented as a HTTP client/server application written in Perl. It uses modules implemented in an existing summarizer geared towards the Germanic languages, a Persian stop-list in Unicode format and a small set of heuristic rules.

The Common Prior Assumption (CPA) is central to the economics of information and the foundations of game theory. Recent contributions (Dekel and Gul, 1997, Gul, 1996, Lipman, 1995) have questioned its meaningfulness in situations of incomplete information where there is no ex ante stage and the primitives of the model are the individuals’ belief hierarchies. We address this conceptual issue by ...

This paper studies menu choice problems in which the decision maker faces no ex ante uncertainty about her ex post preferences, yet nevertheless exhibits non-trivial menu preferences due to the presence of self-control problems. We introduce a new class of utilities which generalize the Gul-Pesendorfer (2001, 2005) ‘No Self-Control’ model. The main results in the paper provide utility represent...

We analyze a two period model of temptation for a finite choice setting. We formalize the idea that temptation depends only on the most tempting alternatives and provide two representations of such preferences. The representation is an ordinal analogue of the self-control preferences in Gul and Pesendorfer (2001). † This research was supported by grants SES9911177, SES0236882, SES9905178 and SE...
