The onset of suicidal ideation in childhood and adolescence

Event history analysis is used to address questions about the timing of first suicidal ideation during preadolescence and adolescence. Are suicidal thoughts atypical during development? Does the age trajectory of suicidal thoughts parallel that of suicidal actions? Do factors that moderate the risk of suicidal actions also moderate the risk of suicidal thoughts, and does their influence vary by developmental stage? Based on life history data from 364 college students, results indicate that suicidal thoughts in childhood are typical and that the risk of such thoughts begins to increase by age nine. Risk rates are affected by demographic factors (gender, race) and by the experience of parental absence. However, the influence of these factors depends on developmental stage, with whites being at increased risk only during adolescence, and parental absence having its strongest effect during preadolescence. In sum, this study suggests that many children and adolescents contemplate suicide, that the risk of doing so begins to increase at an early age, and that clear similarities exist between those groups at heightened risk for suicidal thought and those at heightened risk for suicidal action. Moreover, this study illustrates the power of employing an analytic technique suitable for modeling transitions. Finally, it highlights the need to model differential influences on suicidal ideation at different stages in development.     

China in Global Food Security Governance

The Chinese public's domestic expectation is that its state will ensure a safe and affordable supply of food. However, in doing so, China has acquired large amounts of farmland abroad which has raised concerns among many developing countries. It has been argued that land grabbing in the developing world is a form of neo-colonialism. This role of a colonial power is in conflict with China's historical role, which presents China as a leader of the developing world. In order to bring these role expectations into conformity with each other, China has taken a more active role in global food security governance. It has brought food security to what is becoming the core of the global governance decision-making system, the G20. China's historical role, together with its growing economic power, has helped to push the G20 to understand the importance of food security. This has shifted the G20's understanding of economic global governance away from the traditional fields of banking and trade regulation toward understanding the developmental-oriented economic structure.
