The purpose of this paper is to explain innocent actors in the virtual currency space (e.g. virtual currency exchanges, financial institutions, social media platforms) and how to avoid potential exposure because of the misconduct of users or customers.

Explains how pump-and-dump securities and commodities fraud schemes work, explains the Commodity Futures Trading Commission’s warning to consumers about how to avoid being victimized by schemers running pump-and-dump schemes in the virtual currency space, explains how innocent well-meaning actors may – because of misconduct by their customers or users – be at risk of exposure to victims of pump-and-dump schemes and provides practical guidance for avoiding these dangers and remediating problems.

Market participants must protect their reputations, and they cannot rely on the government to do so for them. Moreover, because investors who fall prey to fraud may be unable to recover from fraudsters, such investors may seek to recover from innocent market participants. Accordingly, market participants should take precautionary measures to avoid being used by fraudsters.

Practical guidance from experienced securities and financial services litigators.

Messner and Rosenfeld have proposed an institutional anomie theory of crime, incorporating the proposition that societal investments in programs to buffer citizens from capricious market forces (decommodification) are inversely related to rates of lethal violence among societies. They support this argument through an analysis of variations in homicide rates among nations. However, the research relevant to their theory is quite limited with numerous claims and arguments yet to be examined. This paper outlines several limitations of the theory and brings data from the World Values Surveys and other sources to bear on their characterization of American culture in comparison to other nations, their arguments about the impact of economic dominance on other institutions, and alternative explanations of the link between decommodification and homicide. Finally, the relevance of the theory to serious property crime is considered and shown to generate serious problems for institutional anomie theory when evaluated as a general theory of crime.

The purpose of this paper is the image segmentation algorithms (ISA) classification analysis, providing for advanced research and design of new computer vision algorithms.

For the development of the required algorithms a three-stage flowchart is suggested. An algorithm of quasi-optimal segmentation is discussed as a possible implementation of the suggested flowchart. A new attribute is introduced reflecting the specific hierarchical algorithm group, which the proposed algorithm belongs to. The introduced attribute refines the overall classification scheme and the requirements for the algorithms under development.

Optimal approximation generation is a computationally intensive task. The computational complexity can be reduced using a hierarchical data framework and a set of auxiliary algorithms, contributing to overall quality improvement. Because hierarchical solutions usually are distinctively suboptimal, further optimization to them was applied. A new classification attribute, proposed in this paper allows to discover previously hidden «blank spots», having decomposed the two-tier ISA classification scheme. The new classification attribute allows to aggregate algorithms, yielding multiple partitions at output and assign them to a dedicated group.

The originality of the paper consists in development of a high-level ISA classification, as well in introduction of a new classification attribute, pertinent to iterative algorithm groups and to hierarchically structured data presentation algorithms.

Purpose – This chapter uses preventive and responsive policing strategies in tandem to develop a multi-level theory that explains the relationship between the police and violence.

Design/methodology/approach – The chapter brings together classical scholarship and more recent sociological research to demonstrate that an effective response to violence is critical in upholding the state’s monopoly on violence and that police officers can reduce violence by preventing it and responding to it.

Findings – Theoretical and practical evidence support the balanced use of responsive and preventive policing strategies to reduce violence. Findings from the literature are used to argue that (1) when law enforcement officers do not effectively respond to violence and/or crime prevention strategies are nonexistent in a community, neighborhood crime is increased and (2) when citizens do not perceive law enforcement officers as legitimate and effective agents of authority, they become more likely to engage in violent offending (Tonry, 1995; Tyler, 2006).

Originality/value – Research has supported the effectiveness of “proactive” (Braga, Papachristos, & Hureau, 2014; Weisburd & Telep, 2014) and “reactive” (Nagin, 2013; Paternoster, 2010) policing strategies in reducing violence, but no research has combined strategies of prevention and response to explain the relationship between the police and violence. The theory proposed in this chapter demonstrates the utility of explaining the instrumental and legitimacy functions of the police across various levels and brings under-protection to the forefront of research on policing and violence.

W.E.B. DuBois, in his 1903 collection of writings entitled The Souls of Black Folk, describes what he calls “The Veil,” which succinctly sums up the deadly and adverse experiences of African Americans in the US. With DuBois contemplations of a Veil under which US Blacks alone live and die as context, this paper takes a look at the modern condition of African Americans in the US, whether they continue to exist within DuBois Veil in modern times (twentieth and twenty-first centuries), and if so, to what extent. As a routine examination and inspection of the condition of Blacks in the US, focus is placed on black lives lost, beginning with an appraisal of their size in the US population overtime, and in comparison with other racial and ethnic groups in the US. US census data, health data collected from the Centers for Disease Control and Prevention, and crime data collected from the Federal Bureau of Investigation are examined to construct a composite of the condition of contemporary Blacks in the US as compared to other groups in the US, focusing attention specifically on the rates at which their lives are lost compared to others through infant mortality, low fertility rates, abortion, and high rates of homicide. This analysis concludes with a look at death from homicide before, during, and after the post-1990s drop in the crime rate.

Terrorism has much in common with genocide and sometimes may even be a form of genocide. In this chapter I systematically compare these two phenomena.

Drawing mainly from Donald Black’s work on terrorism and my own work on genocide, I examine the conceptual and theoretical overlap between terrorism and genocide.

Terrorism and genocide are similar and sometimes overlapping, and they occur under similar social conditions – in response to conflicts between socially distant and unequal groups. Conceptually they differ mainly in that terrorism is covert and carried out by civilians, and genocide may not be. The main theoretical difference is that terrorism tends to be upward – against more powerful targets – while genocide tends to be downward – against less powerful targets. Terrorism tends to be less effective than extreme genocide, then, and the most extreme cases have death tolls much lower than the most extreme cases of genocide.

This analysis draws from previous theories of terrorism, genocide, and social control to better place terrorism in a broader sociological context. In doing so it highlights and explains key features of terrorism, and it even helps us to speculate about the future of terrorism. That is, technological advances might in the long run destroy the social conditions conducive to terrorism, thus leading to terrorism’s ultimate demise, but in the short run they might allow terrorists to more effectively kill, leading terrorism to resemble extreme genocide in its deadliness.
