Identifying Counterfeit Cigarettes Using Environmental Pollen Analysis: An Improved Procedure*

Traditional pollen preparation techniques provide clear residues for pollen identification; however, such methods are time-consuming, requiring repeated centrifugation, heating, and digestion with high-concentration hazardous chemicals. Tobacco leaves can effectively trap environmental pollen due to hairy surface and terpene-rich exudates. A new tobacco sample processing method was developed by using different extraction chemistry with surfactant. Marlboro Gold cigarettes were employed as model samples for method development. Parameters critical for pollen extraction, which include number of cigarette sticks used, extraction solution, and extraction temperature, were optimized. By using 1% dishwashing detergent to treat three cigarettes at room temperature, the improved method was able to recover sufficient pollen for microscopic analysis in three repeated centrifuge-washing steps and omit hazardous chemicals involved in traditional methods. We focused on the pollen of common ragweed (Ambrosia artemisiifolia), a plant native to North America, as an indicator to differentiate genuine and counterfeit U.S. brand cigarettes. Results from analyzing randomly purchased genuine (authenticated by forensic examination) and known counterfeit Marlboro Gold provided by law enforcement revealed that a significant amount (39%) of Ambrosia were consistently present in all genuine samples, while counterfeit contained none or only trace count. Similar results were found in other counterfeit U.S. brand cigarettes (all seized in the U.S.) involved in this study as well. Lack of Ambrosia in cigarette strongly indicates the product was not originated in the United States.     

Procedural Change in the UK House of Commons, 1811–2015

Recent research has shown an increasing interest in the historical evolution of legislative institutions. The development of the UK Parliament has received particularly extensive attention. In this article, we contribute to this literature in three important ways. First, we introduce a complete, machine-readable data set of all the Standing Orders of the UK House of Commons between 1811 and 2015. Second, we demonstrate how this data set can be used to construct innovative measures of procedural change. Third, we illustrate a potential empirical application of the data set, offering an exploratory test of several expectations drawn from recent theories of formal rule change in parliamentary democracies. We conclude that the new data set has the potential to substantially advance our understanding of legislative reforms in the United Kingdom and beyond.

Improving the Managerial Capacity of the Federal Government: A Public Administration Agenda for the Next President

The reputation of a president can be enhanced or diminished depending on the quality of federal management. This transition memorandum draws on the insights of the fellows of the National Academy of Public Administration. It urges the next president to (1) set a tone and strengthen organizational infrastructure to promote effective management across government, (2) create an office to monitor potential major risks and ensure adequate response, and (3) pass on to his successor more capable government than he found. Only then can the incoming administration form the basis for short‐term success and longer‐term effectiveness to implement the president’s policy agenda.     

Selling favors in the lab: experiments on campaign finance reform

Campaign advertising can provide benefits to constituencies when used to fund the distribution of useful information, but voters can be harmed if candidates finance such advertising by trading policy favors to special interests in exchange for contributions. We report data from novel laboratory campaign finance experiments that shed light on this tradeoff, and that provide rigorous empirical evidence on formal campaign finance theory. Our key finding is that voters respond to advertising differently between special interest and publicly-financed campaigns, and that the nature of this difference is qualitatively consistent with formal models’ predictions.     

An effectiveness‐based evaluation of five state pre‐kindergarten programs

Since 1980, the number of state pre‐kindergarten (pre‐K) programs has more than doubled, with 38 states enrolling more than one million children in 2006 alone. This study evaluates how five state pre‐K programs affected children's receptive vocabulary, math, and print awareness skills. Taking advantage of states' strict enrollment policies determined by a child's date of birth, a regression‐discontinuity design was used to estimate effects in Michigan, New Jersey, Oklahoma, South Carolina, and West Virginia. For receptive vocabulary, only New Jersey and Oklahoma yielded significant standardized impacts, though two of the three other coefficients were in a direction indicating positive effects. For math, all the coefficients were positive but only Michigan and New Jersey yielded reliable results. The largest impacts were for print awareness, where all five coefficients were positive and four were reliable in Michigan, New Jersey, South Carolina, and West Virginia. The five states were not randomly selected and, on average, have higher quality program standards than non‐studied states, precluding formal extrapolation to the nation at large. However, our sample of states differed in many other ways, permitting the conclusion that state pre‐K programs can have positive effects on children's cognitive skills, though the magnitude of these effects varies by state and outcome. © 2008 by the Association for Public Policy Analysis and Management.

Peace and Security in Africa:Opportunities and Challenges for China-Africa Cooperation

This paper seeks to explore some of the security and conflict dimensions of the China-Africa relationship, illustrating what the challenges are, why they are important and what has been done to meet them. Section one provides a brief overview of the different manifestations of conflict and insecurity on the African continent, highlighting that Small Arms and Light Weapons (SALW) proliferation is a problem that links them all. Section two explores the reasons why China has a stake in the peace and security o...
