In this paper, we show the first descriptive evidence of factors explaining gender wage differences from a unique questionnaire survey that was carried out on a representative sample for the Czech Republic. We observe large wage differences related to gender; without any reasons, Czech women earn on average 77.80% of men’s wages. The survey uncovers that there is a number of differences among m...

This paper brings statistical findings from a survey about the use of UML modeling and model-driven approaches for the design of embedded software in Brazil. The survey provides evidences regarding the maturity of use of UML and model-driven approaches, how they are employed, and which and where the professionals who use them are. Technical, organizational, and social aspects were investigated ...

In this paper, we propose a general model of the survey interaction process. Our framework consists of three components: the survey context, the survey participants, and a descriptive model of the interviewer-respondent interaction process. Because subjective perceptions of the survey context influence the way individuals interpret, ask, and respond to survey questions, we first present a taxon...

Terry Zimmerman & Subbarao Kambhampati Department of Computer Science & Engineering Arizona State University, Tempe AZ 85287 Abstract This paper reports on a comprehensive survey of research work related to machine learning as applied to AI planning over the past 15 years. Major research contributions are characterized broadly by learning method and then into descriptive subcategories. Survey r...

We continue with the task of obtaining a unifying view of process semantics by considering in this case the logical characterization of the semantics. We start by considering the classic linear timebranching time spectrum developed by R.J. van Glabbeek. He provided a logical characterization of most of the semantics in his spectrum but, without following a unique pattern. In this paper, we pres...

This paper studies the descriptional complexity of multi-parallel grammars with respect to the number of nonterminals and selectors, and the length of these selectors. As a result, it proves that every recursively enumerable language is generated by a multi-parallel grammar with no more than seven nonterminals and four selectors of length five.
