This paper proposes an approach for ex-ante welfare analysis under in-kind transfers based on demand system estimation and construction of virtual prices (i.e., the at which beneficiaries would be as well off with subsidy). As application this approach, I study a program randomly transferred either food basket, procured discount in wholesale markets, or equal-cost cash transfer to poor househol...

The field of Operational Modal Analysis (OMA) has recently become an emerging research interest. OMA, also known as Response-Only Modal Analysis, extracts the modal parameters by processing only the system response data. In many experimental measurement situations, the system’s output data series is short in length and buried under potentially correlated noise. In such cases, the separation of ...

Recently, Fielding and Roiko found that information provision affects knowledge of and support for potable recycled water. However, recent cultural-sociological insights suggest that such effects are not universal. A re-analysis of the original data reveals the relevance of cultural predispositions: significant effects only exist in specific subgroups of the population. Only those who are comfo...

Many sophisticated schemes are springing up recently with better characteristics, such as higher capacity and better security. However, if we tune the size of the secret message progressively, most methods do not provide the progressive quality characteristic which means that the relationship between the quality of stego image and the size of the secret message could be represented by a smooth ...

We present probabilistic logic programming under inheritance with overriding. This approach is based on new notions of entailment for reasoning with conditional constraints, which are obtained from the classical notion of logical entailment by adding inheritance with overriding. This is done by using recent approaches to probabilistic default reasoning with conditional constraints. We analyze t...
