Bubble,Bubble,Oil and Trouble

<正>They were racing through Beijing's busy traffic,actually racing,weaving in and out between cars until coming to a halt in front of a traffic light.The vehicle was a small white utility van,with large English lettering painted on the side panel.As our bus edged forward and came parallel with the van,while in an adjacent lane,I could see inside this anxious van two Chinese men laughing and chatting.Were they trying to flee from someone?What was the great rush?Was there an appointment to be kept that demanded the execution of emergency maneuvers in morning traffic?Then I looked again at the characters adorning their vehicle.Their extreme haste suddenly became explicable:The characters read,"Re-Conditioned Oil for Cooking Needs!""Food safety is now a global concern.Even in the United States where strict food supervision and management of safety exist,accidents still occur.Although food safety issues are difficult to eliminate,the United     

Recidivism and Psychiatric Symptom Outcomes in a Juvenile Mental Health Court

Few researchers have examined outcomes in Juvenile Mental Health Courts. Recidivism rates were assessed among 108 predominantly African American (95.3%) youth. Ages ranged from 12 to 18 (M = 15.85, SD = 1.45). Substantially fewer re‐convictions, along with re‐arrests, were exhibited among the treatment group (n = 54) compared to the control group (n = 54) after one year of participation or probation supervision. Psychiatric symptomatology among 21 youth was assessed pre‐ and post‐ intervention using the Comprehensive Behavior Rating Scales‐Self Report. Cohen's d effect sizes indicated substantial reductions in mental health symptoms (.33 ≥ d ≤ .88). Results are consistent with the previous studies of problem‐solving court efficacy.     

Using Patent Data to Assess the Value of Pharmaceutical Innovation

Though many more patents emerge from industry sources, drug-related patents generated in the non-profit setting appear to have greater importance than patents arising from the commercial sector, which helps demonstrate the value non-profit research institutions can have in driving drug development.     

Business surveys and inflation forecasting in China

We use business survey data collected by the People’s Bank of China for inflation forecasting. Some survey indicators lead to enhanced forecasting performance relative to the univariate benchmark model, especially for a period of moderate inflation. However, the estimated models do not do a good job of tracking the recent pickup in Chinese inflation, due to increases in food prices.     

The DNA field experiment: a randomized trial of the cost-effectiveness of using DNA to solve property crimes

We report the results of a prospective, randomized study of the impact and cost-effectiveness of DNA evidence in investigating property crimes, mainly residential burglary. Biological evidence was collected at up to 500 crime scenes in five U.S. cities between 2005 and 2007, and cases were randomly assigned to the treatment and control groups in equal numbers. DNA processing was added to traditional investigation in the treatment group. A suspect was identified in 31% of treatment cases and 13% of control cases. A suspect was arrested in 22% of treatment cases and 10% of control cases. Across the five sites, each additional arrest—an arrest that would not have occurred without DNA processing—cost slightly more than US14,000. In the most cost-effective sites, an additional arrest cost less than US14,000. In the most cost-effective sites, an additional arrest cost less than US4,000. Expanding the use of DNA as an investigative tool has profound implications. Since DNA-led investigations are more costly than business-as-usual, substantial investments will be required to expand the capacity of crime laboratories, police, and prosecutors to use this investigative tool efficiently. In time, such a change may also impact the types of crimes of cases processed in the criminal justice system.

Decentralization: Conceptualization and measurement

Decentralized government institutions are doing more of the work of government than ever before, but there is little agreement about 1) what decentralization means, or 2) how it should be measured. To overcome this confusion, this article builds on standard definitions of decentralization that include three core dimensions: fiscal, administrative, and political. The article offers an empirical test of that definition using factor analysis of data from 1996 for sixty-eight countries. Factor analysis confirms these three core dimensions and generates a score for each case in each dimension, allowing countries to be measured according to their type and degree of decentralization. In future work, these scores can be used for hypothesis testing about the causes and effects of decentralization on important social outcomes. This exercise demonstrates that conceptual confusion need not hamper research when empirical tests can help verify conceptual categories. Aaron Schneider is a political scientist at the Institute of Development Studies at the University of Sussex. His research interests include comparative politics, public finance, and methodology. His current research projects include studies of federalism, decentralization, party systems, budgeting, and taxation. He has conducted research in Brazil and India, and plans to apply the measures derived in this article to study the impact of decentralization.

Legislative genesis and judicial death of a directive: The European Court of Justice invalidated the data retention directive (2006/24/EC) thereby creating a sustained period of legal uncertainty about the validity of national laws which enacted it

The Grand Chamber has ruled that the data retention directive was invalid ex tunc since it seriously interfered with the fundamental rights to respect for private life and protection of personal data and exceeded the limits of the principle of proportionality which are provided for in the Charter. The scope and temporal effects of this ruling should be clarified, especially its legal impacts on national laws of Member States which enacted the directive. In addition, the findings of the Grand Chamber on geographical safeguards have far-reaching implications on the retention and storage of personal data in the EU.
