From Swaddling to Swastikas: A Life-Course Investigation of White Supremacist Extremism

To date, most terrorism research concerned with the long-term development of extremist behavior focuses on patterns of terrorist attacks, long-term responses to extremist violence or organizational longevity of extremist groups. The current study addresses this void in the existing literature by relying on life-history interviews with 91 North American-based former white supremacists to examine the developmental conditions associated with extremist onset. My attention is primarily focused on individual-level experiences; particularly how childhood risk factors (e.g., abuse, mental illness) and racist family socialization strategies generate emotional and cognitive susceptibilities toward extremist recruitment. This type of investigation contributes to terrorism research by emphasizing some of the early childhood and adolescent experiences that may heighten a person’s vulnerabilities to certain pulls associated with ideology and group dynamics more broadly. Overall, findings from the current dissertation build upon developmental-life course criminology and studies within terrorism that address the role of childhood and adolescent risk factors. In particular, I elaborate on the work of Simi and colleagues (2016) and offer additional context as to the precursors that influence extremist onset

The Culture of Violent Talk: An Interpretive Approach

One of the defining characteristics of extremist movements is the adherence to an ideology highly antagonistic to the status quo and one that permits or explicitly promotes the use of violence to achieve stated goals and to address grievances. For members of extremist groups, talk is one of the most concrete manifestations of how adherents communicate their ideas to each other and the general public. These discussions, however, do not necessarily involve a direct correspondence between words and future behavior. To better understand the culture of violent talk, we investigate how white supremacist extremists use these discussions as a rhetorical device that provides them with a sense of doing and an opportunity to express their frustrations and anger. Our analysis is grounded primarily in the ethnographic data we collected on a variety of US white supremacists since 1997. Our investigation offers important insight regarding the interactional qualities of extremist culture as well as policy implications regarding the assessment process

White supremacy can be addictive, and leaving it behind can be like kicking a drug habit.

The 2016 election and the violence in Charlottesville, Virginia, earlier this year have focused the attention of many on to the resurgence of far-right extremism and radicalization. In new research based on interviews with former white supremacists, Pete Simi, Kathleen Blee, Matthew DeMichele and Steven Windisch find that many of those involved in such movements consider themselves as having been ..

Understanding the Micro-Situational Dynamics of White Supremacist Violence in the United States

While substantial effort has been devoted to investigating the radicalization process and developing theories to explain why this occurs, surprisingly few studies offer explanations of the micro-situational factors that characterize how extremists accomplish violence. Relying on in-depth life history interviews with 89 former white supremacists, we analyzed the situational, emotional, and moral considerations surrounding white supremacist violence. Overall, we identified a variety of strategies white supremacists utilize for overcoming emotional and cognitive obstacles required to perform violent action. Furthermore, we also identified the callous effect of habitual violence. We conclude this article with suggestions for future research and recommendations for practitioners addressing terrorism prevention initiatives

Anger from Within: The Role of Emotions in Disengagement from Violent Extremism

There is growing recognition about the similarities between generic criminality and violent extremism. Using data derived from a unique set of in-depth life history interviews with 40 former U.S. white supremacists, as well as previous studies of criminal desistance, we examine the emotional valence that characterizes actors\u27 descriptions of the disengagement process. More specifically, results suggest that negative emotions (i.e., anger and frustration) directed toward the extremist group and oneself function as a catalyst for disengagement. Negative emotions become a source of motivation in re-evaluating the relative importance of the group as it relates to the individual. Ultimately, the reevaluation of the group is essential to the decision to disengage from violent extremism

On the Permissibility of Homicidal Violence: Perspectives from Former U.S. White Supremacists

Drawing upon in-depth life-history interviews with 91 North American-based former white supremacists, we examine how participants perceive homicidal violence as either an appropriate or inappropriate political strategy. Based on the current findings, participants considered homicidal violence as largely inappropriate due to moral concerns and its politically ineffective nature but also discussed how homicidal violence could be an appropriate defensive measure in RAHOWA (Racial Holy War) or through divine mandate. Capturing how white supremacists frame the permissibility of homicidal violence is a step toward better understanding the “upper limit” or thresholds for violence among members who are trying to construct and negotiate a collective identity that involves violent and aggressive worldviews

Barriers to Family Suspicious Activity Reporting (SAR) of Mobilization Behaviors and Pre-Operational Planning: Report to the U.S. Department of Homeland Security

The Nationwide Suspicious Activity Reporting (SAR) Initiative (NSI) is one of many tools used by law enforcement to help prevent terrorism and terrorism-related activity (see Figure 1). In addition to state, local, tribal, and territorial (SLTT) agencies and federal law enforcement, the Department of Homeland Security (DHS) relies on communities to report suspicious behaviors. While much is known about the actual SAR process, 1 less is known about an essential segment of the community: family members. Family members of violent extremists (VE) play an important role in countering violent extremism (CVE), whether by supporting disengagement and deradicalization or by alerting authorities when concerned for the safety of their loved one(s) and/or others. However, due to issues like mistrust and fear of law enforcement, or a general lack of understanding about SAR and the investigative process, family members may be reluctant to report suspicious behaviors. This fundamental issue reduces the effectiveness of any CVE program or policy. It thus warrants an investigation into how law enforcement agencies can better support and promote family members reporting of suspicious activity. This report seeks to determine whether the DHS and the NSI collaborative have protocols to address family engagement in CVE and report suspicious behaviors. The following two research questions will guide the remainder of this report: (1) How do SAR trainings address family engagement in suspicious reporting? (2) How do members of the NSI collaborative perceive family engagement in the SAR process (i.e., report suspicious behavior)

Family Responses to White Supremacist Extremism: Report to the U.S. Department of Homeland Security

Executive Overview: • Families often express some form of disapproval to relatives involved in white supremacist extremism (WSE); • Expressions of disapproval are often limited to “staying out of trouble” or involve limited to no clearly defined intervention; • Families fear “closing doors” will increase the likelihood they will push their relative away; • Families rarely seek out formal assistance from either governmental or non-governmental agencies; • While nearly 34% of the sample received counseling during childhood and/or adolescence, none of those counseling sessions addressed WSE; the counseling focused exclusively on non-WSE issues (e.g., academic failure, generic delinquency, etc.)

γ-Synucleinopathy: neurodegeneration associated with overexpression of the mouse protein

The role of α-synuclein in pathogenesis of familial and idiopathic forms of Parkinson’s disease, and other human disorders known as α-synucleinopathies, is well established. In contrast, the involvement of two other members of the synuclein family, β-synuclein and γ-synuclein, in the development and progression of neurodegeneration is poorly studied. However, there is a growing body of evidence that α-synuclein and β-synuclein have opposite neuropathophysiological effects. Unlike α-synuclein, overexpressed β-synuclein does not cause pathological changes in the nervous system of transgenic mice and even ameliorates the pathology caused by overexpressed α-synuclein. To assess the consequences of excess expression of the third family member, γ-synuclein, on the nervous system we generated transgenic mice expressing high levels of mouse γ-synuclein under control of Thy-1 promoter. These animals develop severe age- and transgene dose-dependent neuropathology, motor deficits and die prematurely. Histopathological changes include aggregation of γ-synuclein, accumulation of various inclusions in neuronal cell bodies and processes, and astrogliosis. These changes are seen throughout the nervous system but are most prominent in the spinal cord where they lead to loss of spinal motor neurons. Our data suggest that down-regulation of small heat shock protein HSPB1 and disintegration of neurofilament network play a role in motor neurons dysfunction and death. These findings demonstrate that γ-synuclein can be involved in neuropathophysiological changes and the death of susceptible neurons suggesting the necessity of further investigations of the potential role of this synuclein in disease

Monte Carlo Analysis of Neck Linker Extension in Kinesin Molecular Motors

Kinesin stepping is thought to involve both concerted conformational changes and diffusive movement, but the relative roles played by these two processes are not clear. The neck linker docking model is widely accepted in the field, but the remainder of the step – diffusion of the tethered head to the next binding site – is often assumed to occur rapidly with little mechanical resistance. Here, we investigate the effect of tethering by the neck linker on the diffusive movement of the kinesin head, and focus on the predicted behavior of motors with naturally or artificially extended neck linker domains. The kinesin chemomechanical cycle was modeled using a discrete-state Markov chain to describe chemical transitions. Brownian dynamics were used to model the tethered diffusion of the free head, incorporating resistive forces from the neck linker and a position-dependent microtubule binding rate. The Brownian dynamics and chemomechanical cycle were coupled to model processive runs consisting of many 8 nm steps. Three mechanical models of the neck linker were investigated: Constant Stiffness (a simple spring), Increasing Stiffness (analogous to a Worm-Like Chain), and Reflecting (negligible stiffness up to a limiting contour length). Motor velocities and run lengths from simulated paths were compared to experimental results from Kinesin-1 and a mutant containing an extended neck linker domain. When tethered by an increasingly stiff spring, the head is predicted to spend an unrealistically short amount of time within the binding zone, and extending the neck is predicted to increase both the velocity and processivity, contrary to experiments. These results suggest that the Worm-Like Chain is not an adequate model for the flexible neck linker domain. The model can be reconciled with experimental data if the neck linker is either much more compliant or much stiffer than generally assumed, or if weak kinesin-microtubule interactions stabilize the diffusing head near its binding site
