Decoding hidden darknet networks: What we learned about the illicit fentanyl trade on AlphaBay

The opioid epidemic, impacted from the proliferation of fentanyl, has added impetus to the need to detect fentanyl, sources of fentanyl, and places where fentanyl and drugs adulterated with fentanyl are available. Many darknet marketplaces (DNMs) have rules that ban fentanyl. However, it is unclear how these affect the fentanyl market. Using the AlphaBay DNM as a case study, we conducted mixed methods qualitative research. We scraped and analyzed data from the AlphaBay I2P website using, among other methods, content and social network analysis, to uncover hidden fentanyl networks. Our research highlights the next evolution of darknet marketplaces – the migration of DNMs from Tor to I2P and the methods that can be used identify fentanyl networks, irrespective of where sites are: I2P, Tor, or multihomed on I2P and Tor. Despite its ban in the Global AlphaBay Rules, our research revealed the sale of fentanyl on the AlphaBay DNM. Unlike previous studies, our findings predominantly revealed the covert sale of fentanyl on AlphaBay and predatory vendors selling illicit drugs, which unbeknownst to buyers, contained fentanyl. To a lesser extent, our findings identified the overt sale of fentanyl patches on AlphaBay. Although we examined only one DNM, the prevalence of the covert sale of fentanyl and the presence of predatory vendors underscores the importance of research that decodes the language of vendors who surreptitiously sell fentanyl or drugs adulterated with fentanyl or other illicit substances. The results of our research can inform strategies aimed at disrupting and dismantling DNM fentanyl networks.     

Understanding State Rulemaking Processes: Developing Fracking Rules in Colorado,New York,and Ohio

Rulemaking is an integral component of environmental policy at both the federal and state level; however, rulemaking at the state level is understudied. With this research, we begin to fill that gap by focusing on rulemaking regarding the issue of hydraulic fracturing (fracking) in three states: Colorado, New York, and Ohio. This policy issue is well suited to begin exploring state‐level rulemaking processes because the federal government has left fracking regulation to the states. Through semistructured interviews with a range of actors in the rulemaking process across these states, we establish a foundation from which future research in this area may build. This exploratory research yields some valuable insights into the roles different stakeholders are playing in regulating fracking in these three states, and our findings may be useful for explaining state‐level rulemaking more generally.     

Weak Power Bargaining with China: Mongolia and North Korea in comparative perspective

This article examines Mongolia's and North Korea's bargaining with the People's Republic of China to provide insight into Northeast Asian regional dynamics and weak state bargaining behavior. The article demonstrates how both Mongolia and North Korea (which it demonstrates are weak states) employ a variety of tactics within the categories of capitulation, neutrality and confrontation when managing their respective relations with China. The article also argues the applica`bility of the two case studies to a better understanding of the diplomatic challenges China faces as it continues its development and to China's relations with the various weak states on its periphery.     

Informal Social Controls,Procedural Justice and Perceived Police Legitimacy: Do Social Bonds Influence Evaluations of Police Legitimacy?

Although procedural justice has been a key predictor of police legitimacy, recent findings illustrate that other factors influence this outcome (i.e., low self-control and ethnic identity). However, no research to date has evaluated whether individual-level informal social controls impact police legitimacy evaluations. Survey data are used to examine the influence of parental attachment, school commitment and procedural justice on perceived police legitimacy. While procedural justice significantly predicted legitimacy evaluations, no significant relationships were observed between parental attachment, school commitment and police legitimacy. The effects of procedural justice on legitimacy assessments, however, were modestly significantly moderated by parental attachment and school commitment. To maintain legitimacy, police officers should interact with citizens in procedurally fair manners. These results should also be of value concerning how parents and schools legally socialize adolescents.

Modeling the effects of changing issue salience in two-party competition

For a given distribution of voter ideal points, candidates may compete, not only by changing their policy platforms, but also by seeking to persuade voters to place more weight on one of the given dimensions. We do not examine persuasion mechanisms, per se, but, rather, investigate how change of the salience weights can lead to alternation of majorities for the candidates, even though candidate positions remain fixed. Thus, competition over the salience of issue dimensions can, under certain circumstances, be crucial for determining election outcomes. We illustrate potential non-monotonicities in priming effects in terms of the Fourier series decomposition of the distribution of voter preferences, showing that the existence of higher-level harmonics leads to greater uncertainty about election outcomes and about best heresthetic strategies. We then demonstrate the empirical relevance of our results with data on two issue dimensions of political competition in the 2000 U.S. presidential election.     

Informing the Electorate? How Party Cues and Policy Information Affect Public Opinion about Initiatives

Citizens in representative democracies receive party endorsements and policy information when choosing candidates or making policy decisions via the initiative process. What effects do these sources of information have on public opinion? We address this important question by conducting survey experiments where citizens express opinions about initiatives in a real‐world electoral context. We manipulate whether they receive party cues, policy information, both, or neither type of information. We find that citizens do not simply ignore policy information when they are also exposed to party cues. Rather, citizens respond by shifting their opinions away from their party's positions when policy information provides a compelling reason for doing so. These results challenge the prominent claim in public opinion research that citizens blindly follow their party when also exposed to policy information. They also suggest that efforts to inform the electorate can influence opinions, provided that citizens actually receive the information being disseminated.     

The Effect of Providing Breakfast in Class on Student Performance

Many schools have recently experimented with moving breakfast from the cafeteria to the classroom. We examine whether such a program increases achievement, grades, and attendance rates. We exploit quasi‐random timing of program implementation that allows for a difference‐in‐differences identification strategy. We find that providing breakfast in class relative to the cafeteria raises math and reading achievement by 0.09 and 0.06 standard deviations, respectively. These effects are most pronounced for low‐performing, free lunch‐eligible, Hispanic, and low body mass index students. A lack of differences by exposure time and effects on grades suggest that these impacts are on test‐taking performance rather than learning. At the same time, the results highlight the possibility that measured achievement may be biased downwards, and accountability penalties may be inappropriately applied, in schools where many students do not consume breakfast.     

Virtual Tool Mark Generation for Efficient Striation Analysis,

This study introduces a tool mark analysis approach based upon 3D scans of screwdriver tip and marked plate surfaces at the micrometer scale from an optical microscope. An open‐source 3D graphics software package is utilized to simulate the marking process as the projection of the tip's geometry in the direction of tool travel. The edge of this projection becomes a virtual tool mark that is compared to cross‐sections of the marked plate geometry using the statistical likelihood algorithm introduced by Chumbley et al. In a study with both sides of six screwdriver tips and 34 corresponding marks, the method distinguished known matches from known nonmatches with zero false‐positive matches and two false‐negative matches. For matches, it could predict the correct marking angle within ±5–10°. Individual comparisons could be made in seconds on a desktop computer, suggesting that the method could save time for examiners.
