Smoke in the Looking Glass: Effects of Discordance Between Self- and Peer Rated Crowd Affiliation on Adolescent Anxiety, Depression and Self-feelings

Peer crowds serve as an identity marker for adolescents, indicating their image and status among peers; but adolescents do not always endorse peer appraisals of crowd affiliation. We report on two studies—one with 924 adolescents in grades 7–12 and a second with a more diverse population of 2,728 students in grades 9–11, followed for 2 years—that examined how congruence between peer and self-appraisals of crowd affiliation relate to self-esteem and internalizing symptoms. Analyses indicate that high-status crowd members may suffer and low-status crowd members benefit by denying their peer crowd affiliation, but effects are modest in size and not entirely consistent across the two studies. Findings underscore the value of symbolic interactionist principles concerning reflected appraisal processes in understanding how peer crowd affiliation affects adolescent self-image.

Community Privilege and Environmental Justice: An Agent‐Based Analysis

Several theories compete to explain observed race‐ and ethnicity‐based environmental injustice in society. This paper focuses on analyzing the extent to which firms' siting decisions based on community privilege can explain this outcome. A unique feature of this analysis is that we include analysis of both unwanted land uses (disamenity firms) and desired land uses (amenity firms). The environmental justice analysis of amenities other than green spaces is rare, but amenities are crucial components of urban areas to which environmental justice studies must attend. We use an agent‐based model to explore community outcomes when environmental disamenities choose locations based on low community privilege, and compare this with scenarios in which disamenities only seek to minimize the cost of land. We also assess differences in environmental justice outcomes when amenities choose locations in areas with high community privilege. While disamenities' focus on locating in areas with low community privilege indeed affects environmental equity, the effect of amenity location is also important, and there are powerful interaction effects. The importance of privilege‐based location is found in these simulations regardless of which social group—majority or minority—is assumed to be the privileged group. This study suggests a limitation of EJ policies and models that focus on the politics of disamenity siting without considering the politics of amenity siting.

Grappling with the “real politics” of systemic corruption: Theoretical debates versus “real‐world” functions

A growing body of research argues that anticorruption efforts fail because of a flawed theoretical foundation, where collective action theory is said to be a better lens for understanding corruption than the dominant principal–agent theory. We unpack this critique and advance several new arguments. First, the application of collective action theory to the issue of corruption has been, thus far, incomplete. Second, a collective action theory‐based approach to corruption is in fact complementary to a principal–agent approach, rather than contradictory as is claimed. Third, applications of both theories have failed to recognize that corruption persists because it functions to provide solutions to problems. We conclude by arguing that anticorruption effectiveness is difficult to achieve because it requires insights from all three perspectives—principal–agent theory, collective action theory, and corruption as serving functions—which allows us to better understand how to harness the political will needed to fight corruption.     

Liberalism and the anxiety of belief

Anxiety about perceived threats to liberal freedom has played a double role in liberalism. On the one hand, such anxiety has driven the development of liberal institutions aimed at safeguarding freedoms. Yet another, problematic, side of this anxiety can also be found in the history of liberalism and in the policies and practices of contemporary liberal states. From the beginning, liberal intolerance of those perceived to be connected, through religious affiliation or beliefs, with arbitrary or absolute power and therefore deemed to pose a threat to the existing order has justified social exclusion and, in many cases, systematic violence. Rae’s article examines the theoretical and political roots of this distinctive form of liberal anxiety, tracing the connection between anxiety about Catholicism and Catholics in John Locke’s time and contemporary anxieties about the relationship between Islamism and Muslims in liberal states.     

A simple DNA extraction method for marijuana samples used in amplified fragment length polymorphism (AFLP) analysis

As a first step in developing a molecular method for the individualization of marijuana samples, we evaluated a plant DNA extraction kit. The QIAGEN plant DNeasy method uses a spin column format for recovery of DNA and is effective for obtaining high molecular weight DNA from leaf, flower (bud), and seed samples of marijuana. The average DNA yield was 125-500 ng per 100 milligrams of fresh plant tissue. The recovered DNA was of polymerase chain reaction (PCR) quality as measured by the ability to generate reproducible amplified fragment length polymorphism (AFLP) profiles. AFLP is a technique used to create a DNA profile for plant varieties and is being applied to marijuana samples by the authors to link growers and distributors of clonal material. The QIAGEN plant DNeasy method was simple, efficient, and reproducible for processing small quantities of marijuana into DNA.     

Delayed elimination in humans after ingestion of colchicine: Two fatal cases of colchicine poisoning

Colchicine has been widely used in the treatment of acute gout over the years, but it has a narrow therapeutic index, and overdose can be life threatening. A method using ultra-high-performance liquid chromatography–tandem mass spectrometry system was applied in two fatal cases of colchicine poisoning in this study to the determination of colchicine in blood. In case 1, a 19-year-old man suffered from depression and ingested 160 colchicine tablets (each 0.5 mg). The concentration of colchicine in his blood samples showed a fluctuating trend and kept above the therapeutic steady-state concentration for 5 days. In case 2, a 70-year-old female patient with a history of gout and chronic colchicine intake ingested five times the usual dose of colchicine (5 mg) and died after 12 days of medical care, with 5 ng/mL of colchicine in her blood sample. Our findings suggest that the delayed elimination and accumulation in humans after colchicine overdose could keep the concentration of colchicine maintaining above the therapeutic steady-state concentration for many days before dying, probably along with a fluctuating trend.     

Research on detection techniques for pattern modifications of playing cards used in illegal gambling operations

We investigated pattern-modified marked cards used in fraudulent gambling cases in Korea. These cards are printed with modifications to some of the repeated marks on the back, revealing the hand on the front and enabling fraudsters to deceive their victims. We proposed a method for identifying the modified part by first enhancing the card's color difference using an image processing technique and then calculating the similarity between the repeated basic patterns with a Siamese network. This method is fast and convenient, as it can determine the deformation with only 1 or 2 cards and can be implemented in mobile applications, allowing law enforcement officers to investigate quickly. The proposed method serves as a useful tool to aid document examiners in making judgments, as it does not require expensive equipment and effectively visualizes the alterations.
