Turned on or turned out? Campaign advertising, information and voting
Article history: Received 3 June 2009 Received in revised form 3 May 2011 Accepted 9 May 2011 Available online 16 May 2011 We present results from laboratory experimental elections in which voter information is endogenously provided by candidates and voting is voluntary. We also compare advertisements that are costless to voters with those that reduce voter payoffs. We find that informative adv...
متن کاملTurned on by genotoxic stress
Genomic stability is crucial to maintain cell viability and avoid errors in control of proliferation that often lead to disease. Cell cycle checkpoints have evolved as molecular mechanisms to prevent this problem. DNA damage or DNA replica-tion stress during S phase activates the intra-S phase checkpoint, which ensures faithful DNA replication by multiple mechanisms, including inducing expressi...
متن کاملWhat gets turned on in the rhizosphere?
The rhizosphere, the soil fraction closely associated with plant roots, consists of a complex environment conditioned by plant exudates and abiotic conditions. This zone is rich in microbial activity which takes part in biological and ecological processes important for plant health. As a result, many studies dealing with the rhizosphere focus on microbial ecology and physiology and more specifi...
متن کاملPlant retrotransposons: Turned on by stress
Virtually all genomes contain transposable elements. In some organisms, especially plants, transposable elements or sequences derived from them can exceed 50 % of genomic DNA. Some people believe that these elements are simply parasitic entities that flourish because they can out-replicate their host, the genome of which provides numerous safe havens both within and between genes [1]. According...
متن کاملSurviving anoxia with the brain turned on.
Crucian carp is one of few vertebrates that tolerate anoxia. It maintains brain ATP during anoxia partially by reducing ATP consumption. However, unlike turtles, which become comatose during anoxia, this fish remains physically active. This striking difference in anoxic survival strategy is reflected all the way down to the cellular level.
