Driven to Failure: An Empirical Analysis of Driver’s License Suspension in North Carolina

A person’s interest in a driver’s license is “substantial,” and as the U.S. Supreme Court has observed, the suspension of a license by the state can result in “inconvenience and economic hardship suffered,” including because a license may be “essential in the pursuit of a livelihood.” However, forty-four U.S. states currently require indefinite suspension of driver’s licenses for non-driving-related reasons, such as failure to appear in court or pay fines for traffic infractions. There are no systematic, peer-reviewed analyses of individual-level or county-level data regarding such suspensions. This study describes North Carolina’s population of suspended drivers and assesses how driver’s license suspension statutes operate relative to geography, race, and poverty level. First, it analyzes four decades of active-suspension data in North Carolina and finds over 1,225,000 active suspensions for failures to appear or pay traffic fines, amounting to one in seven adult drivers in the state. Second, it compares these data to county-population data; county-level traffic-stop data, collected as required by statute in North Carolina; and county-level data on the volume and composition of traffic court dockets. This study reveals that driver’s license suspensions are not associated with either the volume of traffic stops or the size of the traffic court docket. In contrast, we find that black and Latinx people are overrepresented relative to the population. Linear mixed-level modeling regression analyses demonstrate that the population of white people below the poverty line and black people above the poverty line are most strongly associated with more suspensions. Finally, this Article explores implications of these results for efforts to reconsider the imposition of driver’s license suspensions for non-driving-related reasons. These patterns raise constitutional concerns and practical challenges for policy efforts to undo such large-scale suspension of driving privileges

Exciton-polariton emission from organic semiconductor optical waveguides

We photo-excite slab polymer waveguides doped with J-aggregating dye molecules and measure the leaky emission from strongly coupled waveguide exciton polariton modes at room temperature. We show that the momentum of the waveguide exciton polaritons can be controlled by modifying the thickness of the excitonic waveguide. Non-resonantly pumped excitons in the slab excitonic waveguide decay into transverse electric and transverse magnetic strongly coupled exciton waveguide modes with radial symmetry. These leak to cones of light with radial and azimuthal polarizations

Preliminary report on two Triassic dicynodonts from Zambia.

Main articleThe purpose of this communication is to establish the presence of a species of Stahleckeriid, hitherto known only from India, in the Zambian Triassic N'tawere Formation and to establish the new specific name of the Kannemeyeria specimen also recorded from the same locality. The skulls and some post-cranial material of these two dicynodonts were collected by Mr. James Kitching from the Luangwa Valley, Zambia in 1961. The material comes from Locality 16, of the Lower Fossiliferous Horizon in the N'tawere Formation. One large skull has been assigned to genus and species Rechnisaurus cristarhynchus Roy Chowdhury, 1970. The other skull and the postcranial material has been named Kannemeyeria latirostris sp. nov. One other specimen has been described from this locality, Diademodon rhodesiensis (Brink 1963), which marks it as being of near Cynognathus-zone age.Non

Automatically Guilty: Associations Between Evidence and Guilt

Both real-life cases and laboratory research demonstrate that confession evidence is very convincing—even when it should not be. Could this be due to an automatic association between a confession and guilt? We tested this possibility using a Deese-Roediger-McDermott (DRM) list, which measures automatic associations by presenting participants with a list of words that are thematically related but, importantly, lack the word describing the theme (“critical lure”). When the association between the list words and the theme is sufficiently strong, participants incorrectly report seeing the critical lure. We hypothesized that participants would show more false recall for seeing “guilty” on a “guilty”-themed DRM list when the list included evidence that is automatically associated with guilt, such as “confession” and “DNA.” Although our previous research on this topic found no significant effects, we addressed limitations of that research in three studies using an Amazon MechanicalTurk sample. Our first study addressed a possible ceiling effect by decreasing the associative strength of our “guilty” list. Our second study increased external validity by presenting our DRM List as a DRM Story—a narrative format that provides context for the list words. Our third study investigated the effects of priming evidence quality on the association to guilty. Overall, we found little support for our hypotheses. Across all three studies, we did not detect any effects of the evidence type (Study 1, 2, and 3) or prime type (Study 3). We did, however, find several interesting trends in the data. We discuss explanations for the lack of significant findings and address directions for future research. Specifically, adapting this paradigm for other research applications and to increase our understanding of the memorial effects of the “guilty” DRM list

Rethinking the Ken Through the Lens of Psychological Science

Canadian courts regularly exclude psychological expert evidence that would explain the factors that produce mistaken eyewitness identifications and false confessions (two significant sources of wrongful convictions). Courts justify these exclusions on the basis that the evidence is not beyond the ken of the trier of fact—the psychologist would simply be describing an experience shared by the judge and jury. In this article, the authors suggest this reasoning rests on two fundamental misunderstandings of psychology: unconscious neglect and dispositionism. In other words, judges mistakenly assume the trier of fact understands the unconscious situational forces that distort memories and cause innocent people to confess. Moreover, judges appear to prefer dispositional evidence of some disorder or syndrome suffered by the accused or by the witness to the crime. After demonstrating evidence of such reasoning in several decisions, the authors suggest reforms based on a more nuanced understanding of human psychology

Fat transforms ascorbic acid from inhibiting to promoting acid-catalysed N-nitrosation

<b>Background</b>: The major potential site of acid nitrosation is the proximal stomach, an anatomical site prone to a rising incidence of metaplasia and adenocarcinoma. Nitrite, a pre-carcinogen present in saliva, can be converted to nitrosating species and N-nitroso compounds by acidification at low gastric pH in the presence of thiocyanate. <b>Aims</b>: To assess the effect of lipid and ascorbic acid on the nitrosative chemistry under conditions simulating the human proximal stomach. <b>Methods</b>: The nitrosative chemistry was modelled in vitro by measuring the nitrosation of four secondary amines under conditions simulating the proximal stomach. The N-nitrosamines formed were measured by gas chromatography–ion-trap tandem mass spectrometry, while nitric oxide and oxygen levels were measured amperometrically. <b>Results</b>: In absence of lipid, nitrosative stress was inhibited by ascorbic acid through conversion of nitrosating species to nitric oxide. Addition of ascorbic acid reduced the amount of N-nitrosodimethylamine formed by fivefold, N-nitrosomorpholine by .1000-fold, and totally prevented the formation of N-nitrosodiethylamine and N-nitrosopiperidine. In contrast, when 10% lipid was present, ascorbic acid increased the amount of Nnitrosodimethylamine, N-nitrosodiethylamine and N-nitrosopiperidine formed by approximately 8-, 60- and 140-fold, respectively, compared with absence of ascorbic acid. <b>Conclusion</b>: The presence of lipid converts ascorbic acid from inhibiting to promoting acid nitrosation. This may be explained by nitric oxide, formed by ascorbic acid in the aqueous phase, being able to regenerate nitrosating species by reacting with oxygen in the lipid phase

Variations in caffeine and chlorogenic acid contents of coffees: what are we drinking?

The effect of roasting of coffee beans and the extraction of ground coffee with different volumes of hot pressurised water on the caffeine and the total caffeoylquinic acids (CQAs) content of the resultant beverages was investigated. While caffeine was stable higher roasting temperatures resulted in a loss of CQAs so that the caffeine/CQA ratio was a good marker of the degree of roasting. The caffeine and CQA content and volume was determined for 104 espresso coffees obtained from coffee shops in Scotland, Italy and Spain, limited numbers of cappuccino coffees from commercial outlets and several instant coffees. The caffeine content ranged from 48–317 mg per serving and CQAs from 6–188 mg. It is evident that the ingestion of 200 mg of caffeine per day can be readily and unwittingly exceeded by regular coffee drinkers. This is the upper limit of caffeine intake from all sources recommended by US and UK health agencies for pregnant women. In view of the variable volume of serving sizes, it is also clear that the term “one cup of coffee” is not a reproducible measurement for consumption, yet it is the prevailing unit used in epidemiology to assess coffee consumption and to link the potential effects of the beverage and its components on the outcome of diseases. More accurate measurement of the intake of coffee and its potentially bioactive components are required if epidemiological studies are to produce more reliable information
