Crop models predict that recent and future climate change may have adverse effects on crop yields. Intentional deflection of sunlight away from the Earth could diminish the amount of climate change in a high-CO2 world. However, it has been suggested that this diminution would come at the cost of threatening the food and water supply for billions of people. Here, we carry out high-CO2, geoengineering and control simulations using two climate models to predict the effects on global crop yields.
Emerging infectious diseases (EIDs) pose international security threats because of their potential to inflict harm upon humans, crops, livestock, health infrastructure, and economies. The following questions stimulated the research described in this paper: What infrastructure is necessary to enable EID surveillance in developing countries? What cultural, political, and economic challenges stand in the way of setting up such infrastructure? And are there general principles that might guide engagement with developing countries and support EID surveillance infrastructure?
Matthew Kroenig's argument for preventive military action to combat Tehran's nuclear program -- "Time to Attack Iran" (January/February 2012) -- suffers from three problems. First, its view of Iranian leaders' risk calculations is self-contradictory. Second, it misreads nuclear history. And third, it underestimates the United States' ability to contain a nuclear Iran.
For the past two decades China has been a poster child of successful globalization, integrating with the world and in the process lifting millions of citizens out of poverty. But China’s integration into the world economy and global trends drive and constrain Beijing’s ability to manage growing social, economic and political challenges.
Despite the fact that sub-Saharan Africa in 2012 contains much of the world’s unutilized and underutilized arable land, a significant and growing share of Africa’s farm households live in densely populated areas.
Postdoctoral Fellow Ben Lessing explains how Mexico's new president, Enrique Peña Nieto, may differ significantly from his predecessor in dealing with the country's drug war. Felipe Calderon's policy was intended to crush the cartels with a "no quarter" approach but led to smaller, splintered groups that battle violently for power. Lessing demonstrates through his research that crackdowns create more incentives for bribery, which ultimately leads to more violence and intimidation. Peña Nieto's middle path may lay the foundation to break Mexico's cycle of violence.
The nuclear weapons news of late has been alarming. David Sanger reported in "The New York Times" on January 9 that Iran's top nuclear official had announced his country was near initiating uranium enrichment at a new plant. And the recent leadership change in North Korea means added uncertainty about one of the world's most unpredictable nuclear weapons states. Both developments mean the danger is rising that nuclear weapons or the means to make them will spread in this year.
OVER the last three years, as I delved into the world of American nuclear weapons, I felt increasingly as though I had stepped into a time warp. Despite the nearly total rearrangement of the international security landscape since the demise of the Soviet Union in 1991, the rise of Islamic terrorism and the spread of nuclear materials and technology to volatile nations like Pakistan, North Korea and Iran, the Defense Department remains enthralled by cold war nuclear strategies and practices.
The sixth session of the Korea-U.S. West Coast Strategic Forum was held in the Bechtel Conference Center at Stanford University on June 8, 2011. Established in 2006 by Stanford University and now convening semi-annually alternating between Stanford and Seoul, the Forum brings together distinguished South Korean (Republic of Korea, or ROK) and American scholars, experts, and former military and civilian officials to discuss North Korea, the U.S.-ROK alliance, and regional dynamics in Northeast Asia. Stanford University’s Walter H.
To examine the frequency and predictors of out-of-home placement in a 30-month follow-up for a nationally representative sample of children investigated for a report of maltreatment who remained in their homes following the index child welfare report.
Few studies have examined the link between health system strength and important public health outcomes across nations. We examined the association between health system indicators and mortality rates.
Venture capital investment has become globalized in the business landscape. Scholars
have reported an increasing globalization trend in the VC industry, as measured by VC
investment across national borders (Wright et al., 2005). Aylward (1998) found that Asian
"Whether China and the United States maintain basically cooperative or fundamentally antagonistic relations obviously has very different implications for the region and for the prospects and policies of others in—and beyond—NEA," states Thomas Fingar in the chapter "Alternate Trajectories of the Roles and Influence of China and the United States in Northeast Asia and the Implications for Future Power Configurations" (One Step Back? Reassessing an Ideal Security State for Asia 2025, 2011).

One hundred years after the deportations and mass murder of Armenians, Greeks, Assyrians, and other peoples in the final years of the Ottoman Empire, the history of the Armenian genocide is a victim of historical distortion, state-sponsored falsification, and deep divisions between Armenians and Turks. Working together for the first time, Turkish, Armenian, and other scholars present here a compelling reconstruction of what happened and why.
