This book examines what happens to shareholders of both bidding and target companies in takeovers. Its results show that when a takeover bid is made, the stock prices of all firms involved tend to get up, when stock prices go up, shareholders gain wealth, which increases the wealth in the overall economy. Therefore takeovers in the Australian economy are to be regarded as highly positive. (DÜI-Sbt)

Society's increasing interactions with technology are creating extensive "digital traces" of our collective human behavior. These new data sources are fuelling the rapid development of the new field of computational social science. To investigate user attention to the Hurricane Sandy disaster in 2012, we analyze data from Flickr, a popular website for sharing personal photographs. In this case study, we find that the number of photos taken and subsequently uploaded to Flickr with titles, descriptions or tags related to Hurricane Sandy bears a striking correlation to the atmospheric pressure in the US state New Jersey during this period. Appropriate leverage of such information could be useful to policy makers and others charged with emergency crisis management. ; T.P., H. S. M., S. R. B. and P.
