On the joint use of licensing and liability

Licensing is a widely used technique applied to impose regulations. Firms inducing harm must hold a license issued by a regulatory agency on a case-by-case basis. A firm may also be subject to liability. This paper studies the implications on social welfare of combining licensing with strict liability. Contributions include the study of a joint use and related administrative costs. The latter include costs pertaining to litigation and the issuing and enforcing of licenses. It is established when a joint use is motivated. Regulatory compliance should protect from liability in order to decrease litigation and enforcement costs and associated distortions.     

Under the Law: Legal Consciousness and Radical Environmental Activism

A growing body of sociolegal scholarship focuses the study of law away from formal texts and legal institutions and toward the experiences and perceptions of “everyday” citizens. This study introduces seventeen “radical” environmentalists who engage a repertoire of tactics that includes some actions that involve relatively severe forms of illegality. This research seeks to investigate the role of civil disobedience and lawbreaking within the radical environmental movement and the corresponding legal consciousness of movement actors. Utilizing ethnographic fieldwork and content analysis, this analysis suggests that Ewick and Silbey's (1998 ) three‐tiered model of legal consciousness is an operative starting point, but could be enhanced through theoretical expansion. This study proposes a new category of legal consciousness—Under the Law—that views the law as the protector and defender of a social order that is fundamentally illegitimate. Under the Law is qualitatively different from existing conceptualizations of legal consciousness and reaffirms the mutually constitutive nature of law and society.     

Distance,services, and citizen perceptions of the state in rural Africa

In most poor countries, basic services in rural areas are less accessible and of lower quality than those in urban settings. In this article, we investigate the subnational geography of service delivery and its relationship with citizens' perceptions of their government by analyzing the relationship between service access, satisfaction with services and government, and the distance to urban centers for more than 21,000 survey respondents across 17 African countries. We confirm that access to services and service satisfaction suffer from a spatial gradient. However, distant citizens are less likely than their urban peers to translate service dissatisfaction into discontent with their government; distant citizens have more trust in government and more positive evaluations of both local and national officials. Our findings suggest that increasing responsiveness and accountability to citizens as a means of improving remote rural services may face more limits than promoters of democratic governance and citizen‐centered accountability presume.     

What to do with all these Bayes factors: How to make Bayesian reports in deception research more informative

Bayes factors quantify the evidence in support of the null (absence of an effect) or the alternative hypothesis (presence of an effect). Based on commonly used cut‐offs, Bayes factors between 1/3 and 3 are interpreted as evidentially weak, and one typically concludes there is an absence of evidence. In this commentary on Warmelink, Subramanian, Tkacheva, and McLatchie (Legal Criminol Psychol 24, 2019, 258), we discuss how a Bayesian report can be made more informative. Firstly, this implies a departure from the labels provided by commonly used cut‐offs when reporting Bayes factors. Instead, we encourage researchers to report the value of the Bayes factors, or to convert these values into nominal support for the hypotheses. Secondly, researchers can provide recommendations to design follow‐up studies by examining the posterior distribution of the magnitude of the effect size. Lastly, we show how individual Bayes factors can be evaluated in the context of large‐scale meta‐analyses.     

Mast cell tryptase and hemolysis after trauma

BACKGROUND: We have previously found increased mast cell tryptase in accidental deaths due to trauma, indicating that mast cell degranulation had occurred. The present study was designed to confirm the previous observation and to determine if tryptase release after trauma is acute or delayed. Furthermore, the importance of hemolysis and direct trauma to the mast cells was investigated. MATERIALS AND METHODS: Mast cell tryptase was measured in post-mortem blood from the femoral vein in 27 cases of death from trauma and in 27 control cases by means of a commercially available immunoassay. The trauma cases were further classified into groups with single versus multiple trauma, and groups with short survival time (i.e. death at the scene of the accident) versus longer survival time (death in hospital). In five multi-trauma deaths, blood was sampled locally from the sites of crush injury. RESULTS: The mean value of tryptase in femoral vein blood was 35.6+/-34.6 microg/l in the entire trauma group and 14.7+/-6.5 microg/l in the controls (P<0.005). In bloody liquid sampled from crush injuries, tryptase was substantially elevated in all cases, with a mean of 227+/-146 microg/l. In cases with short survival time, tryptase was significantly higher than in those who died after several hours or days in hospital (P<0.001). No statistically significant difference was seen between multi- and single-trauma cases. A correlation between hemolysis in the samples and elevated tryptase was found only in the trauma cases (P<0.05), but experimentally induced hemolysis in vitro was not found to influence the measurements. CONCLUSION: Mast cell tryptase becomes elevated in trauma deaths and this seems to be ascribable either to direct mechanical injury to tissue mast cells and/or to cell lysis. In patients initially surviving severe injuries, the effects of massive release of histamine and other mast cell mediators might be of importance for treatment strategies and prognosis.

Proper assessment of the JFK assassination bullet lead evidence from metallurgical and statistical perspectives

The bullet evidence in the JFK assassination investigation was reexamined from metallurgical and statistical standpoints. The questioned specimens are comprised of soft lead, possibly from full-metal-jacketed Mannlicher-Carcano (MC), 6.5-mm ammunition. During lead refining, contaminant elements are removed to specified levels for a desired alloy or composition. Microsegregation of trace and minor elements during lead casting and processing can account for the experimental variabilities measured in various evidentiary and comparison samples by laboratory analysts. Thus, elevated concentrations of antimony and copper at crystallographic grain boundaries, the widely varying sizes of grains in MC bullet lead, and the 5-60 mg bullet samples analyzed for assassination intelligence effectively resulted in operational sampling error for the analyses. This deficiency was not considered in the original data interpretation and resulted in an invalid conclusion in favor of the single-bullet theory of the assassination. Alternate statistical calculations, based on the historic analytical data, incorporating weighted averaging and propagation of experimental uncertainties also considerably weaken support for the single-bullet theory. In effect, this assessment of the material composition of the lead specimens from the assassination concludes that the extant evidence is consistent with any number between two and five rounds fired in Dealey Plaza during the shooting.
