The lack of a consistent theoretical framework for understanding the social context in which terrorist organizations emerge and operate stifles the systematic study of terrorism and inhibits the ability of the social sciences to influence international policy. To address this limitation, the present study begins by defining terrorism, and the related phenomena of terror, terrorist, and terrorist organization. As classification is necessary for any scientific investigation, typologies of terrorism currently found in the academic literature are reviewed next. Finally, a criminological framework is applied to the study of terrorist organizations and the environments in which they operate. The primary purpose of the present investigation is to determine whether a classic criminological theory, social disorganization theory, can be applied to the study of terrorist organizations. Drawing from several cross-national data sources, this study operationalizes Shaw and McKay's (1942; 1969) original measures of social disorganization, residential stability, ethnic heterogeneity, and socioeconomic status, at the macro-level of the nation-state. A curvilinear relationship between measures of social disorganization and the hosting of terrorist organizations in each nation-state is predicted. That is, terrorist organizations are expected to require some degree of social organization to operate but, beyond a certain point, social organization is predicted to have an inhibitive effect on the functioning of these organizations, as strong institutions emerge to control this and other forms of collective violence. / Master of Science

The neighbourhood is an essential arena for adolescents’ health development and research suggests that perceived neighbourhood insecurity (PNI) is associated with socio-economic status and self-rated health. The present study explored the distribution of adolescents’ PNI and its association with psychosomatic health complaints across districts. It also examined gender differences and whether family socio-economic position, foreign background and previous exposure to crime could explain part of the association. Data came from classroom-surveys within Stockholm municipality’s 14 districts in 2010, 2012 and 2014 (n=10,291). Linear and logistic multilevel regression models were applied. Results showed that the average level of PNI varied considerably between districts and were strongly connected to its socio-demographic composition. However, individual characteristics in terms of family background and previous exposure to crime only explained a minor part of the variation in PNI across districts. Girls reported more insecurity than boys in all districts. Gender differences in PNI decreased in absolute numbers, but increased in relative numbers, as the overall ‘neighbourhood safety’ increased. Between-district differences in health were minor, but PNI was still a strong predictor of individual-level health, especially for boys. Furthermore, the predictive power of PNI on health was stronger in districts perceived as safer.

This paper investigates whether a new conceptual framework, Neighborhood Ritual Integrity (NRI), addresses the concepts of social capital, collective efficacy, and rituals in a manner which makes it applicable to sociological research. Neighborhood Ritual Integrity (NRI) is a conceptual framework developed in response to various studies, which have established a relationship between neighborhood demographics, structural neighborhood features, crime and adolescent behaviors. Kiser et al., (2007) identified six dimensions that influence short and long term community functioning: Ritual Integrity, Daily Routines, Role Clarity, People and Organizational Resources, Deliberate Planning, and Meaning Making as aspects of NRI. Each dimension describes either a structural or cultural component of community level processes that could affect positive features of neighborhood life. Results from focus group data are examined for the existence of responses consistent with the conceptual definitions of NRI as well as social capital, collective efficacy, and rituals in hopes that this investigation will develop a more comprehensive sociological approach to the study of neighborhoods.

There is a growing recognition that to more fully understand the complex dynamics of neighborhoods and communities, we must effectively link the micro- and macro-level dimensions of community processes. As important as collective efficacy at the macro level has been shown to be, literature looking at factors shaping the individual-level experience is relatively scarce. Since the latent community attribute of collective efficacy is largely measured as a function of individual perceptions, understanding what affects the individual is vital, especially in light of within-neighborhood heterogeneity. In this study, I use insights from social disorganization theory, the systemic model to community attachment, and a life-course perspective in order to examine why age is associated with perceptions of collective efficacy. Utilizing Wave 1 L.A.FANS data (N=2,619), results show that age is positively associated with perceptions of collective efficacy, but that this relationship is indirect, with plans to move as the key mediator between age and perceptions of collective efficacy. Surprisingly, other factors linked to social disorganization theory and the systemic model of community attachment are not important for explaining the age relationship. Overall, this study takes the next step at identifying significant predictors of individual perceptions of collective efficacy both from the structural macro-level perspective and the individual micro-level perspective. Additionally, this analysis adds another urban context to the literature by analyzing Los Angeles County, a distinct area from those most looked at in previous studies.

Numerous medical and environmental toxicology studies have established a link between lead (Pb) exposure, crime, and delinquency. In human environments, lead pollution- like crime- is unequally distributed, creating lead hot spots. In spite of this, studies of crime hotspots have routinely focused on traditional sociological predictors of crime, leaving environmental predictors of crime like lead and other neurotoxins relatively unaddressed. This study attends to this gap in the literature by asking a very straightforward research question: Is there a relationship between hotspots of lead and hotspots of crime? Furthermore, what is the nature and extent of this relationship? Lastly, is the distribution of lead across communities relative to race, class, and/or ethnicity? To explore these issues, a series of thirteen research hypotheses are derived based on findings from previous lead and crime studies. To test these research hypotheses, data was collected from the city of Chicago's Community Areas (n = 77) in Cook County, Illinois. Information from a range of secondary sources including the U.S. Census, Environmental Protection Agency, Chicago Police Department, and City of Chicago are merged and analyzed. Cross sectional and longitudinal assessments are conducted, and results from a series of negative binomial regressions, fixed effects negative binomial regressions, and correlations are presented. Findings suggest the association between lead and crime appeared particularly robust with respect to rates of violent index crime, but less so for rates of property index crime. Contrary to what prior research suggests, the association between lead and crime appears stronger for rates of arrests for adult index crimes than rates of arrests for juvenile index crime arrests. This study concludes by discussing theory and policy implications alongside recommendations for future study.

This thesis investigated the role that local environmental factors play in influencing perceptions of crime and safety across three neighbourhoods within the Region of Peel, Ontario. Semi-structured interviews were conducted with local experts to examine their perceptions of crime and safety, and elements of the built and social environment that may influence these perceptions and identified dimensions of social capital that serve as pathways through which broader environmental determinants of crime and safety can become embedded at the local neighbourhood level. Findings of this research revealed that the perceived relationships between the social and built environment and crime are complex and that dimensions of social capital such as informal social ties serve as a mediator between the environment and perceptions about crime and how perceived and actual crime may be reduced by modifying elements of the built and social environment in order to strengthen local dimensions of social capital.

Social disorganization theory proposes that neighborhood characteristics, such as residential instability, racial and ethnic heterogeneity, concentrated disadvantage, and immigrant concentration contribute to an increase in crime rates. Informal social controls act as a mediator between these neighborhood characteristics and crime and delinquency. Informal social controls are regulated by members of a community and in a disorganized community these controls are not present, therefore, crime and delinquency flourish (Sampson, 2012). Researchers have focused on these measures of social disorganization and the ability to explain a variety of crimes, specifically public crimes. Recently, researchers have focused their attention to characteristics of socially disorganized areas and the ability to predict private crimes, such as domestic violence. This study contributes to the research on social disorganization theory and domestic violence by examining domestic offenses at three different units of analysis: Chicago census tracts, Chicago neighborhoods, and Illinois counties. Demographic variables from the 2005-2009 American Community Survey were utilized to measure social disorganization within Chicago census tracts, Chicago neighborhoods, and Illinois counties. Data on domestic offenses in Chicago were from the City of Chicago Data Portal and data on domestic offenses in Illinois counties were retrieved from the Illinois Criminal Justice Information Authority (ICJIA). This study incorporated geographic information systems (GIS) mapping to examine the relationships between locations of domestic offenses and the measures of social disorganization in each unit of analysis. Results of this study indicate that different measures of social disorganization are significantly associated with domestic offenses in each unit of analysis.
