Studies of possible variables influencing development of posttraumatic stress (PTSD) are of great importance in the effort to enhance preventive and interventional methods in the aim to prevail this devastating condition. Despite the vast research in adults, little is still known of adolescents. Although research is scarce, attachment style has been identified to be an influencing factor in adu...

This study analyzes U.S. news media coverage of the second Gulf War, to determine how individuals used the term ‘videogame’ in reference to the war. By studying how the news media itself sought to praise or criticize coverage of the war as being un/like videogames, we can see how videogames continue to be constructed in popular media in troublesome ways. Analysis, for example, shows that use of...

Dr Cherry was invited by the Ministry of Health/ Ministry for the Environment of New Zealand to carry out a peer-review of the proposal to adopt the ICNIRP guidelines for cell sites in New Zealand, in November 1999. The ICNIRP guidelines were covered by a published assessment in 1998. This review shows that the assessment had ignored all published studies showing chromosome damage. It was highl...

Binocular rivalry has been used to investigate neural correlates of visual awareness. For this investigation to succeed, however, it is necessary to know what rivals during binocular rivalry. Recent work has raised questions about whether rivalry is between eyes or between stimuli. We find that stimulus rivalry occurs only within a limited range of spatial and temporal parameters--otherwise eye...

a rival, and we can confidently recommend it to those who wish to improve their knowledge on this too often neglected subject. It will not of course compare with the larger volumes that come to us across the Atlantic, but they are too large and diffuse for the ordinary reader. The illustrations are few but excellent, being mostly reproductions of photographs. The only fault we have to find is, ...

Some African grey parrots (Psittacus erithacus), the most famous being Pepperberg's parrot Alex, are able to imitate human speech and produce labels referentially. In this study, the aim was to teach ten African grey parrots from two laboratories to label items. Training three parrots from the first laboratory for several months with the Model/Rival method, developed by Pepperberg, in which two...

Some empirically minded philosophers of science argue that the evidence should choose the best theory from among theoretical rivals. However, the evidence may not speak clearly, a problem of ‘underdetermination of theory by data’. We examine this problem in a concrete setting, rival theories of smoking behaviour. We investigate whether several uncontested pieces of empirical evidence allow us t...

We study how conflict in contest games is influenced by rival parties being groups and by group members being able to punish each other. Our motivation stems from the analysis of socio-political conflict. The theoretical prediction is that conflict expenditures are independent of group size and of whether punishment is available or not. We find, first, that conflict expenditures of groups are s...

Why Mergers Reduce Profits and Raise Share Prices — A Theory of Preemptive Mergers* by Sven-Olof Fridolfsson and Johan Stennek We explain the empirical puzzle why mergers reduce profits and raise share prices. If being an “insider” is better than being an “outsider,” firms may merge to preempt their partner merging with a rival. The stock-value of the insiders is increased, since the risk of be...
