We conducted laboratory studies to （1） determine if urea can function as a disturbance cue in juvenile convict cichlids and rainbow trout and （2） determine if the background level of urea influences the behavioral response to a subsequent pulse of urea （＇background noise＇ hypothesis）. In the first series of trials, juve- nile cichlids and trout were exposed to urea at varying concentrations （0 to 0.5 mg L-1 for cichlids and 0 to 1.0 mg L1 for trout）. Our results suggest that both cichilds and trout exhibited functionally similar responses to urea and conspecific disturbance cues and that increasing the concentration of urea results in an increase intensity of antipredator behaviour. In the second series of trials, we pre-exposed cichlids or trout to intermediate or high concentrations of urea （or a distilled water control） and then tested for the response to a second pulse of urea at at intermediate or high concentrations （versus a distilled water control）. Our results demon- strate that pre-exposure to urea reduces or eliminates the response to a second pulse of urea, supporting the background noise hy- pothesis. Together, our results suggest that pulses of urea, released by disturbed or stressed individuals, may function as an early warning signal in freshwater prey species展开更多

There is an expositive impasse （it can＇t explain some facts any more） and a communication-comprehensive impasse （within its limits, some facts are not communicable or understandable）. In order to endorse his theory of evolutionism, Darwin develops an argumentative communicating science based on two axes： the facts and the axiomatics. His communicating science follows the next structure： （1） a relation with the starting thesis is established; （2） some evidence are promoted; （3） as the base of the evidence, a motivation is emphasized; （4） as a reason, an axiomatics is assigned to this base; and （5） finally, the facts and the quantifiers are explained by valid conclusions.展开更多

Apart from a heap of debts, there are two young children. His elder son dropped school dne to inability to pay tuition. Li felt very much downhearted in prison. Knowing this, the prison warders volunteer to contribute money and clothing. In just five days, the展开更多

Protection of Human Rights of the Convicted Human rights of the convicted refer to the rights enjoyed or due to be enjoyed by people subject to criminal punishment by virtue of its natural and social attributes. In terms of natural attribute, the convicted are people, despite the fact that they have been sentenced to crmainal punishments. So they should still enjoy human rights. In terms of social attribute, criminals are a special group of people because they have received a negative appraisal by the criminal law due to their criminal behavior （in most cases, a crime is a serious violation of human rights） and, therefore, they enjoy a special legal status, which has made it impossible and improper for them to enjoy the complete human rights just like ordinary people.展开更多
