The purpose of this article is to clarify current and widespread misconceptions about the properties of blockchain technologies and to describe challenges and avenues for correct and trustworthy design and implementation of distributed ledger system (DLS) or Technology (DLT).

The authors contrast the properties of a blockchain with desired, however emergent, properties of a DLS, which is a complex and distributed system. They point out and justify, with facts and analysis, current misconceptions about the blockchain and DLSs. They describe challenges that these systems will need to address and possible solution avenues for achieving trustworthiness.

Many of the statements that have appeared on the internet, news and academic articles, such as immutable ledger and exact copies, may be misleading. These are desired emergent properties of a complex system, not assured properties. It is well-known within the distributed systems and critical software community that it is extremely hard to prove that a complex system correctly and completely implements emergent properties. Further research and development for trustworthy DLS design and implementation is needed, both practical and theoretical.

This is the first known published attempt at describing current misconceptions about blockchain technologies. Further collaborative work, discussions, potential solutions, evaluations, resulting publications and verified reference implementations are needed to ensure DLTs are safe, secure, and trustworthy.

Interdisciplinary teams with members from academia, business and industry, and from disciplines such as business, entrepreneurship, theoretical and practical computer science, cybersecurity, finance, mathematics and statistics, must be formed. Such teams must collaborate with the objective of developing strategies and techniques for ensuring the correctness and security of future DLSs in which our society may become dependent.

The value and originality of this article is twofold: the disproving, through fact collection and systematic analysis, of current misconceptions about the properties of the blockchain and DLSs, and the discussion of challenges to achieving adequate trustworthiness along with the proposal of general avenues for possible solutions.

The very contextual nature of most mitigating evidence runs counter to America’s individualistic culture. Prior research has found that capital jurors are unreceptive to most mitigating circumstances, but no research has examined the capital sentencing decisions of trial judges. This study fills that gap through a content analysis of eight judicial sentencing opinions from Delaware. The findings indicate that judges typically dismiss contextualizing evidence in their sentencing opinions and instead focus predominately on the defendant’s culpability. This finding calls into question the ability of guided discretion statutes to ensure the consideration of mitigation and limit arbitrariness in the death penalty.

While the steep increases in rates of incarceration seen in the United States in the late twentieth century have begun to level out, one form of incarceration has seen more drastic reductions in rates of use in the 2010s: long-term solitary confinement. Across the United States, prisons that once isolated prisoners for decades at a time stand hauntingly empty. The solitary confinement reform movement provides an important lens for examining what happens when an entrenched punitive practice faces widespread and sustained criticism and reveals the multiple paradigms through which reform operates – through politics, litigation, or charismatic leadership.

Many jurisdictions fine illegal cartels using penalty guidelines that presume an arbitrary 10% overcharge. This article surveys more than 700 published economic studies and judicial decisions that contain 2,041 quantitative estimates of overcharges of hard-core cartels. The primary findings are: (1) the median average long-run overcharge for all types of cartels over all time periods is 23.0%; (2) the mean average is at least 49%; (3) overcharges reached their zenith in 1891–1945 and have trended downward ever since; (4) 6% of the cartel episodes are zero; (5) median overcharges of international-membership cartels are 38% higher than those of domestic cartels; (6) convicted cartels are on average 19% more effective at raising prices as unpunished cartels; (7) bid-rigging conduct displays 25% lower markups than price-fixing cartels; (8) contemporary cartels targeted by class actions have higher overcharges; and (9) when cartels operate at peak effectiveness, price changes are 60–80% higher than the whole episode. Historical penalty guidelines aimed at optimally deterring cartels are likely to be too low.

How do racial meanings structure the institution of higher education and the organizations and networks it encompasses? This chapter develops a theory of racial activation to usefully link conceptualizations of race and organizations. This theory examines how racial meanings shape organizational fields, forms or types of organizations, and the strategic use of racial meanings by actors in organizations to create a more robust understanding of the processes by which organizations are themselves made racialized. Predominant scholarship on race can largely be characterized as theorizing the mechanisms by which race is constructed or uncovering the patterns and consequences of inequality along racial lines. Much existing research hovers above at a macro level where national, state, and global powers are understood to impose racial categories, symbols, meanings, and rules onto daily life while higher education has largely been studied as a site where we see the effects of broader social disparities play out. This chapter draws on insights from inhabited institutionalism to develop a theory of racial activation that usefully links conceptualizations of race and organizations to provide an intersectional and interactional approach to the study of fields.

The aim of this article is an analysis of the links between race and psychotic illness, psychiatric diagnosis and treatment, as well as psychiatric, police and prison violence against people with mental health problems. The analysis focuses on Black men who are more frequently diagnosed with schizophrenia and other psychotic disorders and who face more brutal treatment than other people with such diagnoses. We have adopted a multidisciplinary approach which draws insights from psychiatry, psychology, and sociology and challenges the biologistic interpretation of “mental illness.” We take into account the United States and Britain – two countries with large Black minorities and an established tradition of research on these groups. Among the crucial findings of this study are the facts that racial bias and stereotypes heavily influence the way Black men with a diagnosis of psychotic illness are treated by the psychiatric system, police and prison staff, and that the dominant approach to psychosis masks the connections between racism and mental health.
