Physicists shed light on the nanoscale dynamics of spin thermalization

In physics, thermalization, or the trend of sub-systems within a whole to gain a common temperature, is typically the norm. There are situations, however, where thermalization is slowed down or virtually suppressed; examples are when considering the dynamics of electron and nuclear spins in solids. Understanding why this happens and how it can be controlled is presently at the center of a broad effort, particularly for applications in the emerging field of quantum information technologies.

The Military Dynamics of the Syrian Civil War and Options for Limited U.S. Intervention


The crisis in Syria continues with no end in sight, and in the Saban Center's latest Middle East Memo, Breaking the Stalemate: The Military Dynamics of the Syrian Civil War and Options for Limited U.S. Intervention, Saban Center Senior Fellow Kenneth Pollack argues that until there is a breakthrough on the battlefield, there will be no breakthroughs at the negotiating table.

In his paper, Pollack lays out the military advantages and disadvantages of both the opposition and the regime's forces, and looks at how different opportunities for U.S. intervention can affect those critical dynamics. This analysis provides a much-needed counterpoint to the debate over the possible cost of U.S. options in Syria with an analysis of their likely impact on the conflict.

Highlights include:

  • The strengths and weaknesses of the opposition, including: greater numbers, a history of deprivation of political power, the aid of Islamist militias affiliated with the Muslim Brotherhood and Salafist groups, and support from Arab and Western countries.
     
  • The strengths and weaknesses of the regime, including: motivation to defend against a determined majority, a geographic advantage, the remnants of the Syrian armed forces, help of foreign contingents like Hizballah, and the support of foreign countries like Iran and reportedly Russia and China.
     
  • Options for U.S. interventions to break the stalemate, including:
    • Training and equipping the opposition.
    • Stopping the resupply of the regime in order to diminish its ability to generate firepower.
    • Attacking regime infrastructure targets, such as military bases, power-generation plants and transportation choke points like bridges.
    • Establishing and maintaining a no-fly zone.
    • Engaging in a tactical air campaign against regime ground forces.

Labor force dynamics in the Great Recession and its aftermath: Implications for older workers


Unlike prime-age Americans, who have experienced declines in employment and labor force participation since the onset of the Great Recession, Americans past 60 have seen their employment and labor force participation rates increase.

In order to understand the contrasting labor force developments among the old, on the one hand, and the prime-aged, on the other, this paper develops and analyzes a new data file containing information on monthly labor force changes of adults interviewed in the Current Population Survey (CPS).

The paper documents notable differences among age groups with respect to the changes in labor force transition rates that have occurred over the past two decades. What is crucial for understanding the surprising strength of old-age labor force participation and employment are changes in labor force transition probabilities within and across age groups. The paper identifies several shifts that help account for the increase in old-age employment and labor force participation:

  • Like workers in all age groups, workers in older groups saw a surge in monthly transitions from employment to unemployment in the Great Recession.
  • Unlike workers in prime-age and younger groups, however, older workers also saw a sizeable decline in exits to nonparticipation during and after the recession. While the surge in exits from employment to unemployment tended to reduce the employment rates of all age groups, the drop in employment exits to nonparticipation among the aged tended to hold up labor force participation rates and employment rates among the elderly compared with the nonelderly. Among the elderly, but not the nonelderly, the exit rate from employment into nonparticipation fell more than the exit rate from employment into unemployment increased.
  • The Great Recession and slow recovery from that recession made it harder for the unemployed to transition into employment. Exit rates from unemployment into employment fell sharply in all age groups, old and young.
  • In contrast to unemployed workers in younger age groups, the unemployed in the oldest age groups also saw a drop in their exits to nonparticipation. Compared with the nonaged, this tended to help maintain the labor force participation rates of the old.
  • Flows from out-of-the-labor-force status into employment have declined for most age groups, but they have declined the least or have actually increased modestly among older nonparticipants.

Some of the favorable trends seen in older age groups are likely to be explained, in part, by the substantial improvement in older Americans’ educational attainment. Better educated older people tend to have lower monthly flows from employment into unemployment and nonparticipation, and they have higher monthly flows from nonparticipant status into employment compared with less educated workers.

The policy implications of the paper are:

  • A serious recession inflicts severe and immediate harm on workers and potential workers in all age groups, in the form of layoffs and depressed prospects for finding work.
  • Unlike younger age groups, however, workers in older groups have high rates of voluntary exit from employment and the workforce, even when labor markets are strong. Consequently, reduced rates of voluntary exit from employment and the labor force can have an outsize impact on their employment and participation rates.
  • The aged, as a whole, can therefore experience rising employment and participation rates even as a minority of aged workers suffer severe harm as a result of permanent job loss at an unexpectedly early age and exceptional difficulty finding a new job.
  • Between 2001 and 2015, the old-age employment and participation rates rose, apparently signaling that older workers did not suffer severe harm in the Great Recession.
  • Analysis of the gross flow data suggests, however, that the apparent improvements were the combined result of continued declines in age-specific voluntary exit rates, mostly from the ranks of the employed, and worsening reemployment rates among the unemployed. The older workers who suffered involuntary layoffs were more numerous than before the Great Recession, and they found it much harder to get reemployed than laid off workers in years before 2008. The turnover data show that it has proved much harder for these workers to recover from the loss of their late-career job loss.

Dynamic Stalemate: Surveying Syria's Military Landscape


The Syrian uprising has changed significantly since the first signs of localized armed resistance began emerging in late April 2011. Western states and regional countries opposed to President Assad’s rule failed to manage the formation of an organized and representative political and military opposition body over the past three years. Instead, fragmentation of first the opposition, and then the conflict as a whole, has come to pose numerous serious threats to regional and international security and stability.

In a new Policy Briefing by the Brookings Doha Center, Charles Lister analyzes the Western-backed opposition, the spreading influence of jihadi militants, and the evolving capabilities of pro-government forces. With a definitive military victory seemingly out of reach for all sides of the conflict, Lister argues these parties will remain at a standoff until a political solution is reached. However, as armed groups multiply on either side, even an agreement between government and opposition will be unlikely to end the violence.

Lister concludes that Western and regional countries should focus on two core policy objectives. First: the international community should bolster a cohesive opposition that can challenge the Assad regime in battle as well as in negotiations. Second: the international community should aid Syria’s neighbors in managing the violent spillover of the conflict, particularly curtailing the potential for Syria-based jihadi groups to expand their operations beyond the country.

Embracing interdependence: the dynamics of China and the Middle East


In 2013, China surpassed the European Union to become the Middle East and North Africa (MENA) region’s largest trading partner, and Chinese oil imports from the region rival those of the United States. Do China’s growing interests in the Middle East imply a greater commitment to the region’s security? How can China and regional governments reinforce these ties through greater diplomatic engagement?

In a new Policy Briefing, Chaoling Feng addresses the key choices facing Chinese and Middle East policymakers. She finds that China’s continued reliance on a framework of “non-intervention” is being challenged by the region’s divisive conflicts. Indeed, China’s economic interests face mounting risks when even maintaining “neutrality” can be perceived as taking a side. Furthermore, China’s case-by-case, bilateral engagement with MENA countries has hindered efforts to develop a broader diplomatic approach to the region.

Read "Embracing Interdependence: The Dynamics of China and the Middle East"

Feng argues that China and particularly the GCC states must work to further institutionalize their growing economic interdependence. China, drawing on its experiences in Africa and Latin America, should take a more holistic approach to engagement with the MENA region, while enhancing Chinese institutions for energy trading. GCC countries, for their part, should aim to facilitate bilateral investments in energy production and support China’s plans for Central and West Asian infrastructure development projects.

Coupled Contagion Dynamics of Fear and Disease: Mathematical and Computational Explorations

Published version of the CSED October 2007 Working Paper

ABSTRACT

Background

In classical mathematical epidemiology, individuals do not adapt their contact behavior during epidemics. They do not endogenously engage, for example, in social distancing based on fear. Yet, adaptive behavior is well-documented in true epidemics. We explore the effect of including such behavior in models of epidemic dynamics.

Methodology/Principal Findings

Using both nonlinear dynamical systems and agent-based computation, we model two interacting contagion processes: one of disease and one of fear of the disease. Individuals can “contract” fear through contact with individuals who are infected with the disease (the sick), infected with fear only (the scared), and infected with both fear and disease (the sick and scared). Scared individuals–whether sick or not–may remove themselves from circulation with some probability, which affects the contact dynamic, and thus the disease epidemic proper. If we allow individuals to recover from fear and return to circulation, the coupled dynamics become quite rich, and can include multiple waves of infection. We also study flight as a behavioral response.

Conclusions/Significance

In a spatially extended setting, even relatively small levels of fear-inspired flight can have a dramatic impact on spatio-temporal epidemic dynamics. Self-isolation and spatial flight are only two of many possible actions that fear-infected individuals may take. Our main point is that behavioral adaptation of some sort must be considered.”
