Mandatory reporting legislation has been adopted in every state to insure the protection of children from maltreatment. These statutes have become a significant factor in the lives of mental health professionals who work with children and families. Thirty psychotherapists who had made a recent report of child maltreatment on a client in treatment were interviewed about their experiences with reporting and the consequences of reporting for therapeutic relationships. Several potentially problematic consequences and dilemmas were identified by the therapists, including immediate and long-term effects on the therapeutic alliance and course of therapy, and conflicts of interest in working with children and families.  相似文献

The Biden administration faces the opportunity to reset U.S. policy towards Africa and possesses a variety of tools to use in doing so, including traditional diplomacy, economic statecraft, development assistance, and military engagement. With the increased militarization of U.S. foreign policy over the past few decades, there is an unfortunate tendency to default to military engagement when confronted with even remote threats to U.S. national security interests, and Africa is no exception. With vital security interests in Africa, it can be argued that military engagement should be limited in its application and targeted to those situations that do not lend themselves to solution through traditional diplomacy or development assistance.  相似文献

The relation between domestic R&D and imports of technology is examined for 10 countries. Simple regressions revealed strong complementarity for each of the countries. Multiple regressions including GNP per capita and number of scientists and engineers were performed for the five countries with time series for all the variables. Strong complementarity was found between technology imports and domestic R&D and other variables for Japan and South Korea, weak for France, none for Germany and the US. Excluding government-financed R&D in the US resulted in a substitutive relation. Japan revealed a sharp decline in the ratio of technology payments to R&D spending; Korea is following in its steps. Complementarity appears to weaken in later stages as technology development strategies shift from dependent to imitative to autonomous or offensive technology development.  相似文献
