New nondiagonal G2 inhomogeneous cosmological solutions are presented in a wide range of scalar-tensor theories with a stiff perfect fluid as a matter source. The solutions have no big-bang singularity or any other curvature singularities. The dilaton field and the fluid energy density are regular everywhere, too. The geodesic completeness of the solutions is investigated. 04.50.+h, 04.20.Jb, 9...

When the Fed aims for higher inflation, middle-aged, middle-class households, who tend to have big mortgages, benefit at the expense of wealthy retirees, who have a lot of their savings in bank accounts and bonds. Poor and young households are less affected because they are less likely to own homes and their debt burdens are low. In this model, monetary policy not only creates winners and loser...

Data warehouse projects can be characterized as very complex, cross-functional and long lasting. Slogans like ‘think big start small’ or ‘act local think global’ can be found in literature. But most methodologies for data warehousing only focus on technical aspects or short-term project management and do not provide applicable recommendations for coping with the evolution of data warehouse syst...

The combination of decreased income as a result of the RoweCom collapse, cuts in library budgets internationally, and the success of ‘Big Deal’ bundling arrangements has serious repercussions for smaller and society publishers. This paper argues that the scholarly communications environment is going to become increasingly hostile for these publishers and that their best chance of survival may b...

In 2010, the German Federal Ministry of Education and Research started a series of citizens' dialogues on future technologies. In the context of the German history of public participation in technology-oriented policy making, these dialogues are unique for at least two reasons: The Federal Ministry retains the responsibility for the entire process and is heavily involved in its planning, organi...
