The objects of this paper are： human trafficking; ways of trafficking; risk of Albanian society; and investment of the criminal benefits deriving from trafficking in legal economic activities, it is of great importance for the treatment of proactive investigations to the trafficking of human beings. Another important aspect of the trafficking investigations is the investigation of criminal assets and the way how they are used in the economy of the country. In this paper, we stress that the investigation of criminal assets benefited by the crime of trafficking human beings as well as other wealth financed by these assets is important as the investigation of the criminal activity of trafficking itself. Also, we aim to evaluate the necessity of acting of all law enforcement agencies and other state institutions in order to be successful in the fight against the crime of trafficking of human beings. At the end of this paper, we do treat the necessity and the ways of collaboration of law enforcement agencies, NGOs, and structures of local government for rehabilitation of the victims of trafficking and their integration in the social life.展开更多

However, the negotiations between the government and the investors are time-consuming and costly, due to the perspective differences in risk allocation and revenue distribution. Disputes often arise during concession period because of changes in various risks or non-performance of its obligalions, especially when one sector was forced to accept the requirements by the other as a result of the unequal status, the project urgency or other reasons. Only a few PPP projects in China could perform successfully. There is therefore a need to develop an equitable risk allocation mechanism for the delivery of PPP projects in China so as to improve the efficiency of private investment in infrastructure development.展开更多
