The OSCAR (octagonal selection and clustering algorithm for regression) regularizer consists of a `1 norm plus a pair-wise `∞ norm (responsible for its grouping behavior) and was proposed to encourage group sparsity in scenarios where the groups are a priori unknown. The OSCAR regularizer has a nontrivial proximity operator, which limits its applicability. We reformulate this regularizer as a w...

data envelope analysis (dea) is an approach to estimate the relative efficiency of decision making units (dmus). several studies were conducted in order to prioritize efficient units and some useful models such as cross-efficiency matrix (cem) were presented.  besides, a number of dea models with interval data have been developed and ranking dmus with such data was solved. however, presenting a...

although public policy analysis is essential for public policy systems, the lack of public policy analysis is one of the most important problems of public policy making system in iran. thus, this research implemented to achieve a model for analyzing public policies, using multiple grounded theory method, to create theories and models compatible with the country`s conditions. for this purpose, p...

In this study, the comparative advantage of main agricultural products and its relation to cropping pattern was studied in Ilam Province. For data analyzing the comparative advantage and government policies effects indices, Policy Analysis Matrix (PAM) were used. The obtained results for the comparative advantage indices of Domestic Resource Cost (DRC), Social Cost Benefit (SCB) and Net Social ...

In this paper, the value of exchange rate was calculated in order to determine comparative advantage in crops of Sari Township during 2009-2010. Hence, first, comparative advantage indices are estimated by using a policy analysis matrix. The results showed that just wheat has a DRC index of one in the minimum amount of national currency exchange rate value. This indicated the fact that only whe...

background global health policy is created largely through a collaborative process between development agencies and aid-recipient governments, yet it remains unclear whether governments retain ownership over the creation of policy in their own countries. an assessment of the power structure in this relationship and its influence over agenda-setting is thus the first step towards understanding ...
